Radiographic positioning guides provide comprehensive instructions. These instructions ensure accurate patient positioning. Accurate patient positioning is crucial for diagnostic image quality. Diagnostic image quality directly impacts the effectiveness of radiologic technologists in their duties. Radiologic technologists use radiographic positioning guides to produce clear and precise images. Clear and precise images are essential for doctors, they enable doctors to make accurate medical diagnoses.
Alright, folks, let’s dive into the fascinating realm of radiography! Think of it as having superpowers that allow you to peek inside the human body without any need for a scalpel. Radiography, at its heart, is the art and science of using X-rays, those magical electromagnetic rays, to create images of our internal structures. Imagine you’re a detective, and X-rays are your magnifying glass, helping you solve the mysteries hidden beneath the skin.
Now, let’s break it down. Radiography works because different tissues absorb X-rays differently. Bones, being dense, soak up more X-rays and appear white on the image. Softer tissues let more rays pass through, showing up in shades of gray. This difference in absorption is what allows us to see what’s going on inside. It is not magic but pure science and if the images are done correctly, can become an important tool for medical specialists.
A Quick History Lesson
Once upon a time, in 1895, a German physicist named Wilhelm Conrad Röntgen accidentally discovered X-rays while playing around with vacuum tubes. Talk about a eureka moment! He noticed these invisible rays could pass through objects and create shadows on a fluorescent screen. He even took an X-ray of his wife’s hand, which is now the most famous skeletal hand image. And just like that, radiography was born. Can you just imagine the reaction during the first x-ray experiment? What about the looks on the face of the first volunteer for the radiography process? Since then, X-ray technology has come a long way, from bulky glass plates to digital sensors, but the core principle remains the same.
Why Radiography Matters
So, why should you care about radiography? Well, picture this: You’ve taken a nasty fall and suspect you’ve broken a bone. Or maybe you have a persistent cough that just won’t go away. That’s where radiography swoops in to save the day. It is an invaluable tool for diagnosing a wide range of conditions, from fractures and dislocations to infections and tumors. Radiography helps doctors make informed decisions about treatment, whether it’s setting a broken bone, prescribing medication, or planning surgery. In essence, radiography is like having a roadmap of the human body, guiding healthcare professionals every step of the way.
Anatomical Atlas: Your Radiographic Roadmap
Alright, let’s dive into the fascinating world beneath our skin—as seen through the eyes of X-rays! Think of this as your personal tour guide to the skeletal and internal landscape that radiography unveils. We’re talking about the stars of the show: bones, joints, organs, and even those sneaky soft tissues.
Bones: The Skeletal Cast
First up, the bone zone! These are usually the easiest to spot because they’re dense and block X-rays like a brick wall. We’re talking about the big players:
- Femur: The thigh bone, the longest and strongest in the body. Spotting a fracture here is kind of a big deal.
- Tibia: The shin bone. Along with the fibula, it makes up the lower leg. Tibia fractures are very common in sport’s injuries.
- Radius: One of the two forearm bones, located on the thumb side. A radius fracture is commonly associated with wrist injuries.
- Ulna: The other forearm bone, located on the pinky side. It’s partners in crime with the radius and completes the forearm structure.
- Vertebrae: The building blocks of the spine. We look at these guys for everything from scoliosis to slipped discs.
- Skull: Protecting the brain, the skull’s bony plates are key to identifying head trauma.
Joints: Where the Magic Happens
Joints are where bones meet, and where movement happens. Radiography helps us see if they’re behaving themselves:
- Knee: The hinge joint connecting the thigh and lower leg, prone to injuries like ACL tears or arthritis.
- Ankle: Where the leg meets the foot. Sprains and breaks are frequent visitors here.
- Hip: A ball-and-socket joint. We’re on the lookout for dislocations or fractures, especially in older patients.
- Shoulder: Another ball-and-socket joint, super flexible but also easily dislocated.
- Elbow: Allows the arm to bend. Fractures around the elbow are common, especially in kids.
- Wrist: A complex joint with many small bones. Fractures here can be tricky to spot!
Organs: The Inner Workings
Okay, organs are a bit trickier. They’re not as dense as bone, so we often need contrast agents to see them clearly:
- Lungs: We’re checking for pneumonia, tumors, or signs of lung collapse.
- Heart: Size and shape can tell us about heart conditions.
- Abdomen (Liver, Spleen, Stomach): We’re looking for blockages, foreign objects, or signs of organ damage.
- Kidneys: Shape and size help us spot stones or other abnormalities.
Soft Tissues: The Supporting Cast
Soft tissues like muscles, ligaments, and tendons don’t show up as well on regular X-rays, but we can sometimes see swelling or displacement that hints at problems. MRI is generally better suited for detailed imaging of soft tissues.
Anatomical Landmarks: Your GPS
These are like the road signs of the body, helping us orient ourselves and ensure we’re looking at the right spot:
- Iliac Crest: The top ridge of your hip bone, a key landmark for positioning the pelvis.
- Greater Trochanter: A bony prominence on the femur, important for hip positioning.
- Mastoid Process: The bony bump behind your ear, crucial for skull positioning.
So, there you have it! A quick tour of the anatomical highlights you’ll see in radiography. Armed with this knowledge, you’re one step closer to understanding the amazing images that help doctors diagnose and treat all sorts of conditions!
Radiographic Techniques: Mastering the Art of Projection
Alright, so you’ve got your patient ready, the machine is humming, but which angle do you choose? Radiography isn’t just point-and-shoot; it’s an art! It’s about selecting the right radiographic technique and projection to get the perfect view inside. Think of it like choosing the best camera lens for a photoshoot, except instead of capturing a pretty face, you’re capturing bones, organs, and maybe a sneaky foreign object or two! Let’s dive into the world of radiographic projections and unlock the secrets to capturing those diagnostic-quality images.
Standard Projections: The Bread and Butter
These are your go-to shots, the ones you’ll use every day. They’re the foundation upon which all other radiographic techniques are built.
-
Anterior-Posterior (AP): The X-ray beam enters through the front (anterior) of the patient and exits through the back (posterior). Great for visualizing the chest, abdomen, and extremities. Think of it as the classic “straight-on” shot.
-
Posterior-Anterior (PA): The opposite of AP; the beam goes through the back first. This is typically preferred for chest X-rays as it provides a clearer image of the heart with less magnification.
-
Lateral: A side view! The X-ray beam enters one side of the body and exits the other. Super helpful for seeing depth and relationships between structures.
-
Oblique: Not quite straight on, not quite lateral – somewhere in between. An oblique view is achieved when the central ray of the x-ray beam is directed at an angle from one of the three standard x-ray projections. Excellent for showing structures that might be hidden or superimposed on standard AP or lateral views.
-
Axial: Imagine looking down on a stack of pancakes, This radiographic projection is often used in imaging the head, spine, and feet.
-
Tangential: The X-ray beam is directed to skim along the surface of a curved body part. The patella (kneecap) is a common use of this radiographic projection.
-
Decubitus: This is a horizontal beam projection with the patient lying down. Crucial for detecting air-fluid levels in the chest or abdomen. Think of it as the “laying down” view.
Specific Projections: When You Need a Closer Look
Sometimes, you need to get really specific. These projections are designed to highlight particular anatomical regions and structures.
-
Caldwell (Skull): A PA projection with a specific caudal angle to visualize the frontal and ethmoid sinuses, as well as the orbits.
-
Waters (Sinuses): Another PA projection but with the patient’s nose and chin extended, allowing for optimal visualization of the maxillary sinuses.
-
Towne (Skull): An AP projection with a caudal angulation, perfect for viewing the occipital bone and foramen magnum.
-
Scaphoid Series (Wrist): A set of angled views designed to isolate and visualize the scaphoid bone, which is prone to fractures.
Advanced Techniques: Beyond the Basics
These techniques take radiography to the next level, offering real-time imaging and cross-sectional views.
-
Fluoroscopy: A continuous X-ray beam is passed through the patient, projecting a live image onto a monitor. Think of it as an X-ray movie! Used for guiding procedures and visualizing movement.
-
Tomography: Involves moving the X-ray tube while synchronously moving the image receptor (detector). The result is a blurring of anatomy above and below the plane of interest, leaving that plane “in focus.” Tomography has largely been replaced by CT scanning, but is still applicable for specific purposes.
Essential Equipment: The Radiographer’s Toolkit
Let’s dive into the fascinating world of radiographic equipment! Think of a radiographer as a skilled artisan, and their equipment as the tools of their trade. These tools, both primary and auxiliary, are essential for creating those amazing images that help doctors diagnose and treat us. Without these finely tuned tools, we’d be back in the dark ages of medicine.
Primary Equipment: The Big Guns
These are the core components of any X-ray suite; the essential pieces without which, well, you simply can’t take an X-ray!
- X-Ray Tube: The heart and soul of radiography. This is where the magic happens! It’s a vacuum tube that produces X-rays by bombarding a target with high-speed electrons. The radiographer controls the quantity and quality of the X-ray beam, which in turn affects the image produced.
- X-Ray Table: Think of it as the patient’s stage. It’s a specialized table, often with adjustable height and positioning capabilities, that supports the patient during the examination. It needs to be radiolucent (allowing X-rays to pass through) to avoid interfering with the image. Some tables even tilt, allowing for various radiographic projections.
- Image Receptor (CR/DR Systems): This is what captures the X-ray image after it passes through the patient.
- Computed Radiography (CR) systems use cassettes containing photostimulable phosphor plates. After exposure, the cassette is processed in a CR reader, which scans the plate and converts the stored energy into a digital image.
- Digital Radiography (DR) systems have built-in detectors that convert X-rays directly into digital signals. These systems are faster and more efficient than CR, providing immediate image display.
Auxiliary Equipment: The Supporting Cast
These are the unsung heroes that help ensure the production of high-quality images, while keeping patients and staff safe.
- Grids: These are image clarity enhancers. They are placed between the patient and the image receptor to absorb scattered radiation, improving image contrast and clarity. Think of them as tiny venetian blinds for X-rays!
- Collimators: These are beam shapers. They attach to the X-ray tube and allow the radiographer to control the size and shape of the X-ray beam, reducing unnecessary radiation exposure and improving image quality. Think of them as adjustable curtains that frame only the area of interest.
- Lead Markers: These are the left and right indicators. They are placed on the image receptor to indicate the patient’s left or right side, ensuring proper anatomical orientation. It is crucial for accurate diagnosis.
- Positioning Sponges/Devices: These are the patient comfort specialists. They are used to support and position the patient, ensuring proper alignment and immobilization during the examination. They come in various shapes and sizes, like pillows for X-rays.
- Gonadal Shielding: These are the guardian angels of reproduction. They are used to protect the patient’s reproductive organs from unnecessary radiation exposure. They are made of lead and come in various shapes and sizes.
Radiographic Positioning: It’s All About That Angle (and a Few Other Things!)
Alright, let’s dive into the nitty-gritty of radiographic positioning. Think of it as the art of setting the stage for the perfect X-ray. We’re not just snapping pics here; we’re crafting diagnostic masterpieces! Seriously though, without great positioning, you could easily miss vital information, which could impact patient outcomes. So, let’s get it right.
Lights, Camera… Patient Alignment!
First up, patient alignment. This is where we make sure the body part we’re X-raying is exactly where it needs to be in relation to the X-ray beam and the image receptor (that’s the thing that captures the image). A little off-kilter and BAM! You’ve got distortion, overlap, and a whole lot of frustration.
Angle of Attack: Central Ray Angulation
Next, let’s talk angles! Central ray angulation, or the direction of the X-ray beam, can make or break an image. Imagine trying to photograph a building straight on versus from a weird, tilted perspective. Same thing here! Angling the beam helps us avoid superimposition of structures and get a clearer view of what we’re after.
Breathe In, Breathe Out (or Maybe Hold It!)
Breathing instructions are crucial. Telling a patient to hold their breath during a chest X-ray minimizes motion blur (unless they need imaging during breathing). Simple instruction, massive impact.
The Sweet Spot: Source-to-Image Receptor Distance (SID)
Source-to-Image Receptor Distance (SID): This is the distance between the X-ray tube (the source of the X-rays) and the image receptor. Messing with the SID can affect the magnification and sharpness of your image. There’s a golden spot for each exam, so follow those protocols!
Sizing Things Up: Collimation
Collimation is our spotlight control. By narrowing the X-ray beam to just the area of interest, we reduce the patient’s radiation exposure (yay, safety!) and improve image quality by decreasing scatter radiation (double yay!).
Which Side is Which?: Anatomical Side Markers
Anatomical side markers (left/right): This one’s super straightforward but absolutely critical: Clearly marking which side of the patient is being imaged. It avoids mix-ups and prevents someone from accidentally operating on the wrong side of the body.
Safety First!: Radiation Safety
Radiation Safety: Remember, we’re dealing with X-rays, so minimizing radiation exposure is paramount. Shielding patients appropriately, using the lowest necessary dose, and following all safety protocols are musts.
Staying Still: Immobilization Techniques
Immobilization techniques are like a superhero’s gadget belt for radiographers. Using sponges, sandbags, or even tape (carefully, of course!) can help patients hold still, especially those who might have trouble, like kids or patients in pain.
Keeping it Real: Minimizing Distortion and Magnification
Finally, the art of minimizing distortion and magnification. We want our images to be as accurate a representation of the patient’s anatomy as possible. Proper positioning helps keep things true to size and shape, ensuring we’re not misinterpreting anything due to funky angles or distances.
Pathologies in Focus: What Radiography Reveals
Ever wondered what secrets X-rays can unveil beyond just seeing if you swallowed that Lego piece as a kid? Radiography is like a super-powered magnifying glass for doctors, letting them peek inside your body without any slicing or dicing. It’s not just for broken bones; it can detect a surprising range of conditions, from sneaky fractures to misplaced objects. Let’s dive into some common issues radiography helps us spot!
Common Pathologies: X-Ray Vision in Action
Fractures (various types)
Think of a fracture as a crack or break in a bone – kind of like when you drop your phone (we’ve all been there!). X-rays are the champions at revealing these breaks, whether they’re clean, straight lines, jagged splinters, or even tiny hairline cracks. We’re talking everything from that classic wrist fracture after a rollerblading mishap to stress fractures that marathon runners might get. The cool thing about X-rays is that they help doctors see exactly where the break is and how bad it is, guiding them on the best way to fix it – usually with a cast, a splint, or sometimes even surgery.
Dislocations
Imagine your bones are like puzzle pieces that fit together at your joints. A dislocation happens when those pieces get knocked out of place – ouch! X-rays can clearly show if a bone has popped out of its normal position in a joint, like a shoulder after a particularly enthusiastic volleyball game or a finger after a run-in with a door. Seeing the dislocation on an X-ray helps doctors know how to gently (but firmly!) put things back where they belong.
Foreign Bodies
Okay, this one’s straight out of a cartoon! Ever heard of someone accidentally swallowing a coin or getting a splinter so deep you can’t see it? X-rays are pros at finding these foreign bodies lurking inside you. Metal objects show up really well, but even some non-metallic stuff can be spotted depending on its density. X-rays help doctors locate the exact spot of the rogue object and figure out the safest way to remove it – no more guessing games!
Image Evaluation: Ensuring Diagnostic Accuracy
So, you’ve got your image – fantastic! But wait, don’t just slap it on the patient’s file and call it a day. An image can tell a thousand stories, but only if you know how to listen. Evaluating a radiograph is like being a detective; you’re looking for clues to solve a medical mystery. It’s not just about seeing bones; it’s about ensuring that what you’re seeing is clear, accurate, and tells the whole truth. Let’s break down the essential criteria so you can spot a winning image every time.
Essential Criteria for a Radiographic Masterpiece
Demonstration of Specific Anatomical Structures
First things first: Did you get what you came for? If you’re hunting for a hairline fracture in the scaphoid, then, by golly, the scaphoid better be there, front and center! Ensure the region of interest is fully visualized, without being cropped or obscured. Every relevant anatomical landmark needs to be clearly presented, so the radiologist can confidently assess its condition. Think of it as the main character in your visual story – make sure they have enough screen time.
Optimal Image Density and Contrast
Now, let’s talk about aesthetics – because even in medicine, presentation matters! Density refers to the overall blackness of the image, while contrast is the difference in densities between adjacent structures. Too dark, and everything looks like a shadowy monster; too light, and it’s like searching for ghosts. We’re aiming for that Goldilocks zone: just right. Optimal contrast lets you distinguish between different tissues, making it easier to spot subtle abnormalities. So, tweak those settings until you’ve got a perfectly balanced exposure.
Absence of Artifacts
Artifacts are the uninvited guests at your radiographic party. These can be anything from jewelry and clothing to motion blur and processing errors. They obscure anatomical details and can mimic or hide pathology. A stray necklace might look suspiciously like a fracture, and nobody wants that confusion! Before you hit that exposure button, double-check that your patient is artifact-free and properly positioned.
Sharpness of Detail
Ever tried reading a blurry road sign while speeding down the highway? Not fun, right? Sharpness of detail, or recorded detail, is all about how clearly you can see the fine lines and edges in your image. Factors like focal spot size, patient motion, and screen-film contact can all affect sharpness. The goal is to minimize blur and maximize clarity, so you can confidently identify even the smallest anatomical structures.
Appropriate Collimation
Last but not least, let’s talk about collimation – the unsung hero of image quality and radiation safety. Collimation means restricting the X-ray beam to the area of interest. Not only does this reduce the patient’s radiation exposure, but it also improves image quality by reducing scatter radiation. It’s like putting blinders on a horse – focus on what’s important, and block out the distractions.
The Unsung Heroes Behind the Scenes: Who’s Who in the Radiography Room?
Ever wondered who’s orchestrating the magic behind those incredible X-ray images? It’s not just a machine that spits out pictures; it’s a whole team of dedicated professionals, each playing a vital role in getting you the accurate diagnosis you need. Let’s pull back the curtain and meet the stars of the radiography show!
Radiologic Technologist/Radiographer: The Image Alchemist
Think of the radiologic technologist, or radiographer, as the artist with the X-ray beam. They’re the ones who actually position you, choose the right settings on the machine, and capture the image. They’re your direct point of contact, ensuring you’re comfortable and safe throughout the process.
- Master of Positioning: These pros know anatomy inside and out! They precisely position your body to capture the perfect view of the area in question. It’s like a human puzzle, and they’re the masters of putting the pieces together.
- Dose Detectives: They’re also radiation safety gurus, using their knowledge to minimize your exposure while still getting a high-quality image. They follow strict protocols to keep you and themselves protected.
- Tech Wizards: From setting up the equipment to troubleshooting any technical glitches, they’re the go-to experts for everything related to the X-ray machine and imaging software. They know the ins and outs of the digital radiography system.
Radiologist: The Image Decoder
Now, picture a radiologist as the Sherlock Holmes of the medical world. They’re the doctors who specialize in interpreting medical images, including X-rays, CT scans, MRIs, and ultrasounds. It’s their job to analyze the images and provide a detailed report to your doctor.
- Anatomical Aces: They possess an encyclopedic knowledge of anatomy and physiology, allowing them to spot even the tiniest abnormalities. Their expertise is crucial in identifying fractures, tumors, infections, and other conditions.
- Report Writers Extraordinaire: They’re masters of medical language, crafting comprehensive reports that explain their findings clearly and concisely. These reports help your doctor make informed decisions about your care.
- Consultation Kings/Queens: They’re often consulted by other doctors for their expertise in interpreting complex images and helping to guide treatment plans. They’re the imaging advisors!
Medical Physicist: The Guardian of Radiation
Last but certainly not least, we have the medical physicist, the silent guardian of radiation safety and image quality. They make sure the machines are running smoothly and accurately, and that radiation doses are kept to a minimum.
- Quality Control Commanders: They’re responsible for ensuring that all imaging equipment meets strict performance standards. They conduct regular tests and calibrations to maintain image quality and accuracy.
- Dose Optimization Defenders: They work closely with radiologists and technologists to optimize radiation doses for each patient. They make sure that the benefits of the exam outweigh any potential risks.
- Regulation Rangers: They stay up-to-date on all the latest regulations and guidelines related to radiation safety. They ensure that the radiography department complies with all applicable laws and standards.
So, the next time you’re getting an X-ray, remember the skilled team working behind the scenes to make sure you receive the best possible care! They’re the reason why radiography is such a powerful and reliable diagnostic tool.
Safety and Regulations: Keeping Everyone Safe and Sound (and Not Glowing!)
Alright, let’s talk safety! We all want to be healthy, right? That’s why understanding the rules of the radiography road is so important. It’s not just about getting a good picture; it’s about protecting both the patients and the awesome professionals who make it all happen. Think of it as the “do no harm” pledge, but with a bit more tech involved.
ALARA: As Low As Reasonably Achievable
This isn’t some exotic dance move, but a cornerstone of radiation safety! ALARA stands for “As Low As Reasonably Achievable.” The goal is to minimize radiation exposure without compromising the quality of the image. It’s a bit like adding just enough spice to your food—enough to make it tasty, but not so much that you breathe fire!
Radiation Protection: Shield Up!
Think of it like this: we’re dealing with super-powered X-rays, so we need some safeguards! Radiation protection guidelines are the bread and butter of keeping doses low. It’s a three-pronged approach:
- Shielding: Lead aprons and barriers are like superhero capes for radiation protection. They block the radiation from reaching sensitive areas, kind of like an invisible force field.
- Time: Minimize the amount of time you’re exposed to radiation. It’s like being in the sun; a little is good, but too much can cause problems.
- Distance: The further away you are from the source, the less radiation you receive. Remember that awkward middle school dance? Suddenly, “social distancing” makes a lot of sense, doesn’t it?
Infection Control: Germ Warfare (But in a Good Way)
Hospitals can be breeding grounds for germs, so infection control is crucial. It’s all about preventing the spread of infections through things like:
- Regular handwashing.
- Sanitization of equipment between patients.
- Using disposable covers and barriers where needed.
- Adhering to strict protocols.
Think of it like this: We’re not just taking pictures; we’re also being super mindful about keeping things clean and germ-free for everyone’s sake!
Patient Communication and Consent: Talk It Out!
Patients might be nervous, especially if they don’t know what’s happening. Clear communication is essential. It’s about:
- Explaining the procedure in simple terms.
- Answering any questions they might have.
- Ensuring they understand why the X-ray is needed.
- Obtaining their consent before proceeding.
Essentially, it’s all about building trust and making sure everyone is on the same page! A well-informed patient is a comfortable, cooperative patient. And that leads to better images and a smoother process for everyone involved.
In short, it’s like being a team, working together to ensure top-notch care while keeping safety in the spotlight. That’s how radiography rolls!
Documentation: The Paper Trail of Radiography
Alright, let’s talk paperwork! I know, I know, it’s not the most glamorous part of radiography. But trust me, good documentation is what separates the pros from the, well, let’s just say “less organized.” Think of it as leaving a trail of breadcrumbs for other healthcare providers – and for your future self when you’re trying to remember that one weird case from three years ago.
Basically, if it wasn’t written down, it didn’t happen. In the world of radiography, proper documentation isn’t just a suggestion, it’s the law (okay, maybe not always the law, but you get the point!). It’s about clear, accurate, and legally defensible records.
Radiology Reports: The Grand Finale
The pièce de résistance of our documentation journey? The radiology report! This is where the radiologist, the Sherlock Holmes of medical imaging, lays out their findings. It’s not just “yep, that’s a bone,” it’s a detailed description of what they see, their interpretation, and any recommendations.
A well-crafted radiology report should include:
- Patient Information: Name, ID, date of birth – the essentials to make sure you’re talking about the right person.
- Clinical History: Why was the X-ray even ordered in the first place? Knowing the patient’s symptoms or history helps the radiologist put the images into context.
- Technique: What projections were used? This helps others understand how the images were obtained.
- Findings: This is the meat of the report – a detailed description of what the radiologist sees on the images. Any abnormalities, measurements, and comparisons to previous studies are included here.
- Impression/Diagnosis: The radiologist’s professional opinion. What do they think is going on based on the images?
- Recommendations: Does the patient need further imaging? A biopsy? The report might suggest the next steps.
Anatomical Terminology: Speaking the Same Language
Ever tried to explain to someone where your “funny bone” is, only to get a blank stare? Yeah, that’s why we need standardized anatomical terminology! It’s like a secret language that everyone in healthcare understands.
Using terms like “distal, proximal, medial, and lateral” ensures everyone is on the same page, literally. Instead of saying “the bone thingy near the elbow,” we say “the distal humerus.” Much clearer, right? Accurate anatomical terminology is important for image interpretation.
Radiographic Positioning Terminology: Lights, Camera,… Anatomy!
Just as important as knowing what you’re looking at is knowing how the image was taken. That’s where radiographic positioning terminology comes in. This is where we describe the patient’s position and the direction of the X-ray beam.
For example, saying “AP chest” tells us the X-ray beam went from the anterior (front) to the posterior (back) of the patient’s chest. Other terms like “oblique, lateral, and axial” describe different angles and positions. Knowing these terms is crucial for reproducing images and understanding the radiologist’s interpretation.
