RTE 1401 midterm review Questions and Answers |
2026 Update | 100% Correct.
What increases the anode heel effect
1. increase i.r.
2. decrease SID
3. decrease target angle
For what purpose do we use the anode heel effect?
towards the thicker parts of the pt. body
XR photon properites
invisible light
neutral
speed of light
straight line (heterogenous)
ionize matter
cant focus only restrict
luminescence
polyenergentic
no matter
What are two types of homogenous beam?
scatter
leakage
, How do you decrease scatter?
increase collimation
decrease kVp
Mammo uses how much kVp
40kVp
Where does leakage come from?
the housing
How do you reduce pneumbra?
bottom shutters
How do you reduce off focus ghost
top shutters
What does scatter produce?
fog
What increases pneumbra
OID increase
SID decrease
What is the magnification problem formula?
(OID x 7) + SID =?
What is collimation
