Which of the following controls the degree of contrast on a radiograph?

Question

Quizplus · Accepted Answer

kVp controls the energy of the x-ray beam and therefore affects the degree of penetration and contrast on the radiograph. A higher kVp will result in a lower contrast image with more shades of gray, while a lower kVp will result in a higher contrast image with more black and white areas. Focal spot size, focal-film distance, and mA mainly control the clarity and detail of the image, but not the degree of contrast.
