ACTUAL Exam Questions and CORRECT
Answers
which anatomical part requires the lowest KVP setting to produce quality radiographic image -
CORRECT ANSWER - skull
penetrating power of X-ray beam is controlled by the KVP setting.
thinner parts require less kVp to adequately penetrate the P
an abdominal radiograph is obtained with a traditional film screen imaging system with a
technique of 12 mAs at 68 kVp. the image appears too dark and a repeat image is requested at
one-half the density of the original image. which technique will produce this outcome? -
CORRECT ANSWER - 6 mAs and 68 kVp
it will produce a repeat image with half the density of the original
during which step of automatic film processing are the unexposed silver halide crystals removed
from the film base? - CORRECT ANSWER - fixeing
what is the main purpose of the fixer - CORRECT ANSWER - to remove the unexposed
silver halide from the base and ensure that the image remains intact and permanent.
what does the developer do - CORRECT ANSWER - converts the silver halide into
metallic silver.
what does washing do - CORRECT ANSWER - removes the remaining fixer and
preserves its archival quality.
