What would be the expected outcome if the kVp is reduced during a radiographic procedure?

Reducing the kilovolt peak (kVp) during a radiographic procedure primarily affects the x-ray beam's penetration ability. A lower kVp results in a less penetrating beam, which means that fewer photons can pass through the patient and reach the imaging receptor. This leads to an increase in the overall contrast of the image, typically making it harder to differentiate between tissues with similar densities. As a result, there is a potential for decreased image quality because the radiograph may appear too light, lacking detail, or excessive contrast that can obscure important anatomical structures.

Additionally, a lower kVp may necessitate an increase in exposure time or the use of additional dose to maintain image quality, which could inadvertently lead to increased patient exposure. However, the direct effect of reducing kVp is most evident in the degradation of image quality. This is why the answer underscores the importance of maintaining appropriate kVp settings in order to achieve optimal imaging results while minimizing dose and maintaining radiation safety for both patients and staff.
