Question

Which steps increase contrast in fluoroscopy? (Select the two that apply.)

A. Use a larger collimator field.
B. Increase milliamperes (mA).
C. Use a smaller collimator field.
D. Reduce kilovolts peak (kVp).
E. Increase kilovolts peak (kVp).

Answer 1

To increase contrast in fluoroscopy, you can use a smaller collimator field and increase the kilovolts peak (kVp).

Step-by-step explanation:

The steps that increase contrast in fluoroscopy are:

1. Use a smaller collimator field: A collimator is a device used to restrict the size of the x-ray beam. Using a smaller collimator field allows for better control and focusing of the x-ray beam, resulting in increased contrast.
2. Increase kilovolts peak (kVp): kVp is the peak voltage applied to the x-ray tube, which determines the energy of the x-rays produced. Increasing kVp increases the energy of the x-rays, leading to increased penetration and contrast.
