1. A radiographer can best minimize the amount of scatter radiation reaching the image receptor by restricting the beam. 2. The principal factors that affect the amount of scatter produced are mAs and the type of irradiated material. 3. When kilovoltage is increased with no other changes in technical factors, fewer scattered photons will result. 4. Scattered photons from Compton interactions are of no use in demonstrating radiographic structures of interest. 5. Image quality is improved when scatter reaching the image receptor is reduced. 6. Bone absorbs more radiation and produces more scatter than soft tissue.
