RTE 1401 COMPREHENSIVE EXAMINATION
TEST COMPLETE QUESTIONS WITH
ACCURATE SOLUTIONS
●● Does mAs control contrast
Answer: no
●● What primary controls contrast
Answer: kV
●● How can we reduce scatter
Answer: Grids, reduce mAs, or collimate
●● When using digital what happens to brightness if mAs is increased
Answer: It appears appropriate
●● When using digital what happens to brightness if kV is increased
Answer: It appears appropriate
●● If kV is increased what will happen to the beam penetrability
(increase or decrease)
Answer: Increase
, ●● Does kV affect distortion
Answer: No
●● What is the best way to minimize distortion with SID and OID
Answer: Increase SID decrease OID
●● How does elongation occur
Answer: when the object is parallel to the image receptor but the central
ray (CR) is angled
●● How does foreshortening occur
Answer: when the part is tilted or angled
●● How does motion affect the radiograph
Answer: It decreases detail
●● What are the advantages of increased collimation
Answer: Less scatter and less patient dose
●● How does filtration effect exposure
Answer: they have an inverse relationship, so when filtration is
increased exposure is decreased
