Image magnification can be decreased by
A) increasing the target-object distance.
B) increasing the object-image receptor distance.
C) decreasing the target-surface distance.
D) increasing the focal spot size.
A
Explanation: A) The target-object distance is determined by the length of the PID. When a long PID is used, the x-rays in the center of the beam are more parallel, resulting in less image magnification.
B) The target-object distance is determined by the length of the PID. When a long PID is used, the x-rays in the center of the beam are more parallel, resulting in less image magnification.
