Download : Download high-res … Web27 de fev. de 2016 · As a result, images with lower contrast are produced (Figure 10-6). When a low kVp is used, the x-ray beam penetration is decreased, resulting in more absorption and less transmission, which results in greater variation in the x-ray intensities exiting the patient (remnant). This produces a high-contrast radiographic image (Figure …
