The controlling factors for magnification are:
A) density and contrast.
B) object-to-image receptor distance (OID) and source-to-image receptor distance (SID).
C) central ray angle and central ray alignment.
D) part/image receptor alignment and SID.

Question

Quizplus · Accepted Answer

Magnification is primarily controlled by the object-to-image receptor distance (OID) and source-to-image receptor distance (SID). When the OID is increased, the object appears larger on the image, resulting in magnification. However, if the SID is increased, the object appears smaller on the image, resulting in less magnification. The other factors listed may affect image quality, but they do not directly control magnification.
