Artifacts - ANS-an erroneous portion of an photo or tracing that does not as it should be
represent the situation of the picture or dimension being recorded
atomic structure - ANS-represents the variety of protons within the nucleus of an atom
attenuation - ANS-absorption of the x-ray beam in be counted, generally the human frame
computerized publicity manage (AEC) - ANS-an electronic circuit within the x-ray machine that
robotically terminates the exposure time when a predetermined quantity of x-rays has been
detected.
Basic biologic results of radiation exposure - ANS-1. (acute) excessive dose radiation over a
short time frame 2. (chronic) low doses over an extended period of time 3. DNA harm ensuing in
cellular loss of life; tissue death; four. DNA damage resulting in genetic mutation; 5. DNA
damage ensuing in formation of most cancers cells
beam first-rate - ANS-manipulated by kVp
-refers to photon power
-impacts penetrating ability of beam
beam restrictors - ANS-function to restriction the size of the irradiated area. In doing so, they
restriction the quantity of tissue irradiated (thereby decreasing the share of scattered radiation
generated within the part) and help lessen affected person dose.
Beam restrictors assessment - ANS-An growth in beam restriction effects in much less
radiographic noise (fog) ensuing in multiplied comparison resolution (evaluation); Increasing
beam limit refers to creating the field size smaller - i.E. Changing from 14x17 to 10x12
collimation.
Chemical protection - ANS-Film processing chemistry is poisonous and hazardous to naked
skin; Safe managing requirements need to be honestly marked at the label; Developer is
alkaline in nature; Fixer is acidic
assessment - ANS-the distinction in density among any two adjacent quantities of the
photograph
contrast decision - ANS-the ability of an imaging machine to differentiate anatomical systems of
comparable concern assessment inclusive of liver-spleen and grey depend-white be counted
CR - ANS-computed radiography
definition of x-ray beam depth - ANS-refers to the amount and nice of photons inside the x-ray
beam measured the usage of one of the following: Gray in air (Gy); Air KERMA;
Coulombs/kilogram of air (C/kg); Roentgens (R); Beam depth proportional to kVp squared; mA;
and inversely proportional to distance from the source squared
density - ANS-In film-display screen imaging, optical density refers back to the degree of black
steel silver formed inside the movie emulsion - for this reason forming darker areas of the
picture. For example, lung tissue might be represented as better optical density than bone. In
