Angiography ✔Correct Answer-x-ray imaging of blood vessels after injection of contrast material
Bone Densitometry (BD) ✔Correct Answer-x-ray technique for determining density of bone
Computed Tomography (CT) ✔Correct Answer-computerized system that provides axial images
(slices) of all the body parts
Fluoroscopy ✔Correct Answer-Real-time viewing of x-ray images in motion.
Magnetic resonance imaging (MRI) ✔Correct Answer-a technique that uses magnetic fields and
radio waves to produce computer-generated images of the body
Mammography ✔Correct Answer-x-ray imaging of the breast
Nuclear Medicine ✔Correct Answer-Injection or ingestion of radioactive materials and recording of
their uptake in the body using a gamma camera
Positron Emission Tomography (PET) ✔Correct Answer-highly sophisticated computerized form of
nuclear medicine imaging
Radiation therapy ✔Correct Answer-treatment of malignant diseases using radiation
Sonography ✔Correct Answer-Imaging of soft tissue structures using sound echoes
Typical duties of an x-ray tech ✔Correct Answer-paperwork; making sure the patient is properly
dressed for exam; provide explanation/answers about procedure; assisting the patient into the
proper position; taking the cassette to be processed
X-ray tube ✔Correct Answer-source of x-rays
, Tube housing ✔Correct Answer-Lead-lined covering on the x-ray tube.
Tube port ✔Correct Answer-Opening where the x-rays exit the tube
X-ray beam ✔Correct Answer-focused stream of photons directed at object in a triangular shape
Central Ray ✔Correct Answer-Imaginary line in the center of the x-ray beam
Primary radiation ✔Correct Answer-x-ray beam after it leaves the x-ray tube and before it reaches
the object
Remnant Radiation ✔Correct Answer-All radiation exiting the patient during exposure and
ultimately striking the IR
Scatter radiation ✔Correct Answer-Radiation that is deflected from its path and spreads in all
directions as it strikes matter
Attenuation ✔Correct Answer-absorption of the x-ray beam
Radiation field ✔Correct Answer-The squared area of the x-ray beam that strikes the patient
IR ✔Correct Answer-image receptor; consists of cassette and phosphor plate
Most common cassette size ✔Correct Answer-14x17
Control booth ✔Correct Answer-A separated area or room where the x-ray machine operator can
remain safe from radiation
Does scatter radiation have more or less energy than the primary beam? ✔Correct Answer-less
Who issues an order for an x-ray examination? ✔Correct Answer-the physician
Detent ✔Correct Answer-A special mechanism that tends to stop a moving part in a specific
location
Latent image ✔Correct Answer-invisible image created after exposure but before processing
Visible image ✔Correct Answer-the image present on the film after it has been processed
Device that protects the IR from being fogged by scatter ✔Correct Answer-grid or Bucky
Collimator ✔Correct Answer-Restricts the size and shape of the x-ray beam
How long does radiation linger in the x-ray room? ✔Correct Answer-It doesn't linger or make
things radioactive
Most frequent adverse event in the x-ray room ✔Correct Answer-Falling
Computed radiography ✔Correct Answer-image data are digitized and immediately displayed on a
monitor or recorded on film
