It means, fewer photons reach the image receptor and construct less image receptor exposure. That is why bones appear whiter on radiograph. Also the high kV needed to penetrate the bones. flow allWebThe higher the KvP the more penetrating the primary beam plus more photons will strike the film due to that beam plus scatter, causing the detail to diminish. You have to add at least a 30% change MAs to cause a change in perceived density on the film. flo walking progressive

"Web2 de ago. de 2024 · The air gap technique is not as effective in high kVp settings because the scattered x-rays are aimed in more forward direction. In projections where the kVp selected is below 90, the scattered x-rays are generally directed more to the side and therefore the air gap technique is more effective in removing them 2.
