Absorption - ANS-When all of the x-ray strength is absorbed through the ejected electron
acute radiation syndrome - ANS-Radiation sickness that happens in human beings after
whole-frame doses of 1 Gy (a hundred rad) or extra of ionizing radiation added over a quick
time now not visible in diagnostic imaging
ALARA - ANS-(radiation publicity)As Low As Reasonably Achievable
American Registry of Radiologic Technologists (ARRT) - ANS-The world's largest

enterprise that promotes studies, persevering with schooling and recommendations for
radiography practise
Anatomic Position - ANS-The role wherein the affected person is standing erect; with the
face directed forward, fingers prolonged by the edges with the palms facing ahead, and the
feet pointing anteriorly
Anatomically Programmed Radiography (APR) - ANS-Technique with the aid of which
photos at the console manual the operator in choice of a desired kVp and mAs
Angiography - ANS-The fluoroscopic imaging of blood vessels
Anode - ANS-Positively charged facet of an x-ray tube that incorporates the goal
Anterior-Posterior - ANS-from the front to back
Artifact - ANS-Unintended optical density on a radiograph or every other movie-type picture
receptor
Atom - ANS-Smallest particle of an detail that can't be divided or broken through chemical
means
Atomic Number (Z) - ANS-number of protons inside the nucleus
Attenuation - ANS-absorption of the x-ray beam in depend, normally the human body
Automatic Exposure Control (AEC) - ANS-function/device that determines radiation
exposure all through radiography in most x-ray imaging systems
, Back-up time - ANS-while the publicity timer is manually set with the aid of the operator to a
time greater than the expected publicity time
Bergonie-Tribondeau law - ANS-principle that states that the radiosensitivity of cells is
immediately proportional to their reproductive interest and inversely proportional to their
degree of differentiation
Binding strength - ANS-the power required to split a unmarried particle or institution of
particles from a molecule, atom, or nucleus
Biological Damage - ANS-the damage comprised of exposure to radiation
Bremsstrahlung x-ray - ANS-x-ray that effects from interplay of the projectile electron with a
goal nucleus, additionally called breaking radiation
Bucky Tray - ANS-a device that incorporates a transferring grid
Caliper - ANS-a device used for frame component size
Cardinal Principles of Radiation Protection - ANS-The methods used to guard operators from
unnecessary radiation exposure; time, distance and protecting
Cassette - ANS-A rigid holder that consists of the movie and displays
Cathode - ANS-negative side of the x-ray tube, incorporates the filament and the focusing
cup
Central Ray - ANS-Center of the number one x-ray beam that interacts with the photo
receptor
Characteristic Radiation - ANS-One of forms of x-ray productions. Created while an electron
enters the tungsten anode of the x-ray tube and knocks out a K-shell electron. This
interaction produces an x-ray photon
Coherent Scattering - ANS-Scattering of x-rays with no lack of electricity; additionally
referred to as classical scattering
Collimation - ANS-Restriction of the beneficial x-ray beam to lessen affected person dose
and improve photo contrast
Collimator - ANS-boxlike device attached under the tube housing which lets in the x-ray
operator to vary the beam size and shape
Compensating Filter - ANS-Material Inserted among an x-ray source and a affected person
to form the depth of the x-ray beam
Compton Scattering - ANS-Interaction between an x-ray and a loosely sure outer-shell
electron that outcomes in ionization and x-ray scattering
