RADT 1010- TEST 1 STUDY GUIDE
Bone Densitometry - Answer -the measurement of bone density using dual energy X-
ray absorptometry to detect osteoporosis
Cardiovascular Interventional Technology - Answer -radiologic procedures for the
diagnosis and treatment of the cardiovascular system
Computed Tomography - Answer -recording of a predetermined plane in the body
using an xray beam that uses a computer for display on a monitor. "Slices" of the
human body.
Diagnostic Medical Sonography - Answer -visualization of deep structures of the body
by recording the reflections of pulses of ultrasonic waves directed into the tissue
Energy - Answer -the capacity to do work.
Ionization - Answer -the process of adding or removing electrons from an atom or
molecule, which gives the atom or molecule a net charge.
Magnetic Resonance Imaging - Answer -uses magnetic fields and radio waves to
create sectional images of the body
Mammography - Answer -radiography of the breast
Nuclear Medicine Technology - Answer -branch of radiology that involves the
introduction of radioactive substances into the body for both diagnostic and therapeutic
purposes
Radiation - Answer -energy transmitted by waves through space or a medium
Radiation Therapy - Answer -the treatment of disease (especially cancer) by means of
x-rays or a radioactive substance
Radiography - Answer -making records of internal structures of the body by passing
xrays through the body which acts on film, imaging plate or system
Radiologic Technologist - Answer -General term applied to an individual who performs
radiography, radiation therapy, or nuclear medicine technology
Radiologist - Answer -physician who specializes in the use of xrays and other forms of
radiation in the diagnosis & treatment of disease
, Radiologist Assistant - Answer -an advanced-level radiographer who extends the
capacity of the radiologist in the diagnostic imaging environment, thereby enhancing
patient care
Radiology - Answer -deals with radioactive substances & radiant energy to diagnose
and treat disease by means of ionizing and non-ionizing radiation.
Roentgen Ray - Answer -synonym for x-ray
X-ray - Answer -electromagnetic radiation of short wavelength that is produced when
electrons moving at high velocity are suddenly stopped.
Attenuation - Answer -process by which a beam of radiation is reduced in energy when
passing through tissue or other materials
Automatic Re-scaling - Answer -process by which images are produced with uniform
brightness and contrast, regardless of the amount of exposure
Brightness - Answer -the amt of light emitted from a flat screen monitor
Computed Radiography - Answer -Cassette or cassette based digital radiography is the
digital acquisition modality that uses storage phosphor plates to produce projection
images.
Contrast - Answer -difference between adjacent densities on a radiograph image
Density - Answer -degree of darkening or blackness of exposed & processed
photographic or radiographic film
Digital Radiography - Answer -cassette or casette-less image receptor systems that
convert x-ray energy into a digital electronic signal for manipulation and display
Direct Capture DR - Answer -devices that convert incident x-ray energy directly into an
electrical signal, typically using a photoconductor as the x-ray absorber and a thin-film
transistor as the signal collection area, which then sends the electrical signal to the
computer for processing and viewing
Distortion - Answer -misrepresentation of the true size or shape of an object
Exposure Index - Answer -a numeric representation of the quantity of exposure
received by a digital image receptor
Exposure Latitude - Answer -the range of exposures that can be used and still result in
the capture of a diagnostic-quality image
Fog - Answer -undesirable exposure of the IR

ray absorptometry to detect osteoporosis
