What is one of the effects of increasing tube potential on image receptor exposure?

Increasing the tube potential, often referred to as kVp (kilovoltage peak), directly influences the energy and penetrating ability of the x-ray photons produced in the tube. With a higher tube potential, a larger number of high-energy photons are generated and emitted toward the image receptor. These higher-energy photons can penetrate tissues more effectively than lower-energy photons, which enhances the overall exposure of the image receptor.

The increase in the number of photons results in a greater intensity of radiation reaching the receptor, thereby improving the image quality and reducing the exposure time that may be needed to achieve a diagnostically acceptable image. Additionally, higher tube potential affects the nature of the x-ray beam by increasing both the quantity and quality of the radiation produced.

While increasing kVp can influence factors such as contrast and patient dose, the primary effect on the image receptor exposure is indeed the increase in the number of photons, which is why this answer is correct.
