Question

Why should a radiographer routinely use a small focal spot when imaging extremities?

A. Increase the life of the x-ray tube.
B. Decrease in patient dose.
C. Increase in spatial resolution.
D. Decrease in contrast.

Answer 1

A radiographer should routinely use a small focal spot when imaging extremities because it increases spatial resolution.

Step-by-step explanation:

When imaging extremities, a radiographer should routinely use a small focal spot because it increases spatial resolution. A small focal spot produces a sharper image with greater detail, making it easier to visualize small structures in the extremities, such as bones or soft tissues. This can help with diagnosing fractures, tumors, or other abnormalities.
