Webscatter grid between the patient and detector is the technique used almost universally to reduce the image degradation effect of scatter. Anti-scatter grids are not com-pletely effective in rejecting scattered photons, so the image is still degraded, though to a lesser extent than in the absence of a grid. However, anti-scatter grids are also WebScatter radiation. X-rays that travel in different direction after exiting patient body. Scatter radiation. Primarily a product of Compton interaction. Kilovoltage. Kilovoltage has a direct relationship to scatter radiation production. As X-ray energy increases, the number of photons that undergo Compton interaction also increases. Field Size.
