When a beam-restricting device is used to limit field size, technical factors may need to ____ to compensate for the change in image receptor exposure.
A)be increased
B)be decreased
C)remain unchanged
D)none of the above

Question

Quizplus · Accepted Answer

When a beam-restricting device is used to limit field size, the total amount of radiation reaching the image receptor is reduced. Therefore, technical factors, such as mAs or kVp, may need to be increased to compensate for the reduction in exposure. This will ensure that the image is still of diagnostic quality.
