Question

Scatter radiation can be controlled by:

a. Grids
b. Reducing field size
c. Reducing mAs
d. Increasing kVp

Answer 1

Scatter radiation can be controlled by using grids, reducing field size, and increasing kVp.

Step-by-step explanation:

Scatter radiation can be controlled by:

1. Grids: Grids are designed to absorb scatter radiation and improve image quality by reducing the amount of scatter that reaches the detector.
2. Reducing field size: By using collimators or adjusting the size of the X-ray beam, the field size can be reduced, which decreases the amount of scatter radiation produced.
3. Increasing kVp: Higher kilovoltage peak (kVp) settings create a stronger X-ray beam, which can penetrate the patient more effectively and produce less scatter radiation.
