What is the primary effect of increasing both kVp and filtration on the x-ray beam?

The primary effect of increasing both kilovolt peak (kVp) and filtration on the x-ray beam is an increase in the beam's quality. Elevating the kVp increases the energy of the x-rays produced, allowing them to penetrate through materials more effectively. Higher energy x-rays are more likely to pass through tissues with less scatter and absorption, thus improving image contrast and overall quality.

Simultaneously, adding filtration serves to remove lower-energy photons from the beam, which do not contribute effectively to image quality and only increase patient dose without enhancing the image. As a result, the x-ray beam becomes more "filtered," consisting primarily of high-energy photons that improve image sharpness and diagnostic capability without increasing radiation exposure unnecessary.

This combination of higher energy x-rays due to increased kVp and the reduction of weaker photons through filtration results in a quality improvement. It plays a crucial role in enhancing the diagnostic efficacy of fluoroscopic procedures while also promoting safety for patients.
