As grid ratio increases, patient dose
a. Increases
b. Decreases
c. Remains the same
d. No effect
a. Increases
As collimation increases, the radiographic density will
a. Increases
b. Decreases
c. Remains the same
d. No effect
b. Decreases
Rationale: Increasing collimation (smaller field size) decreases radiographic density; density collimation (wider) increases radiographic density
As collimation increases, the radiographic density will
a. Increases
b. Decreases
c. Remains the same
d. No effect
b. Decreases
Rationale: Increasing collimation (smaller field size) decreases radiographic density; density collimation (wider) increases radiographic density
As OID increases, size distortion will
a. Increases
b. Decreases
c. Remains the same
d. No effect
A. Increases
Rationale: As OID increases, size distortion (magnification) increases
if the collimation increases, what is its effect to the radiographic density?
a. increases
b. decreases
c. remains the same
d. no effect
- Increases
Rationale: As collomation increases, the radiographic density decreases
As SID increases, size distortion (magnification) will?
a. Increases
b. Decreases
c. Remains the same
d. No effect
B. Decreases
Rationale: As SID increases, size distortion (magnification) decreases
What happen to radiographic contrast if the kVp is increase?
a. Increases
b. Decreases
c. Remains the same
d. No effect
B. Decrease
More scatter radiation will be produced if the kvp is increased, therefore, the rad contrast will decrease.
Remember that high contrast is achieved if the kVp is low. But compensation is a must. Lower kVp increases dose of the px
What is the relationship of mA and exposure time when maintaining the same mAs.
a. direct
b. Inverse
c. No relationship
d. Unchanged
B. Inverse
Rationale: mA and exposure time have an inverse relationship when maintaining the same mAs
As the mAs increased, the quantity of radiation increased and radiographic density.
a. Increase
b. Decrease
c. Remains the same
d. varies
A. Increase
R: As the mAs increased, the quantity of radiation increased and radiographic density also increased. DIRECT RELATIONSHIP
