Radiographic Terminology
Terms 'SID' and 'SOD' in radiographic imaging refer to these specific measurements
What are Source-to-Image Distance and Source-to-Object Distance?
The minimum number of projections required when imaging joints in the area of primary interest
What are three projections: AP/PA, Lateral, and Oblique?
This component of a radiographic system produces the X-rays used for imaging
What is the X-ray tube?
The acronym ALARA stands for this in radiation safety
What is As Low As Reasonably Achievable?
The correct workflow sequence for Computed Radiography (CR) imaging
What is cassette placement, patient positioning, exposure, cassette transport, image identification, plate scanning, image display, and archiving?
This radiographic term describes the device that restricts the size and shape of the X-ray beam
What is a collimator?
These are the two main types of table-tops used in radiographic positioning
What are Fixed and Floating table-tops?
The purpose of the Bucky in radiographic imaging
What is to hold the image receptor/cassette and contain a grid that reduces scatter radiation?
These are the three cardinal rules of radiation protection according to ALARA principles
What are Time, Distance, and Shielding?
These positioning markers are used to indicate patient orientation on radiographic images
What are LEFT, RIGHT, SUPINE, PRONE, ERECT, DECUB, etc.?
The abbreviations 'AP' and 'PA' stand for these terms in radiographic positioning
What are Anteroposterior (front to back) and Posteroanterior (back to front)?
The correct term for the patient position where they are lying face up on the imaging table
What is Supine position?
This type of advanced imaging equipment provides real-time X-ray imaging during proceduresWhat is a C-arm fluoroscopy unit?
What is a C-arm fluoroscopy unit?
This protective device must radiographers always wear according to ALARA principles
What is a personnel radiation monitor (dosimeter)?
The purpose of 'film centering' in the radiographic positioning sequence
What is to align the X-ray tube, anatomical area of interest, and image receptor for proper image quality?
The term 'OID' represents this in radiographic imaging
What is Object-to-Image Distance, the distance between the patient and the image receptor?
The correct sequence step that follows 'Part positioning' in the radiographic positioning routine
What is film centering (aligning the Bucky and X-ray tube/detent)?
In computed radiography (CR), this process occurs after the cassette is transported to the ID station
What is image identification with patient ID, then cassette insertion into the reader for plate scanning?
The standard thickness of a lead apron used for radiation protection during fluoroscopy
What is 0.5 mm lead equivalent?
This safety equipment is used to protect patients during fluoroscopy procedures
What are lead drape, lead apron, and Bucky slot cover?
The abbreviation 'IR' stands for this in the context of radiographic imaging
What is Image Receptor, the device that captures the X-ray image after it passes through the patient?
The term that describes the patient position where they are lying face down on the imaging table
What is Prone position?
PACS stands for this in the context of radiographic imaging
What is Picture Archiving and Communication System, where images are stored digitally?
The exposure limit during fluoroscopy procedures according to safety practices
What is 10 R (roentgen) per minute?
The typical monthly radiation dose limit for workers in a radiography setting
What is less than 20 mrem per month?
