Both the radiation dose to the patient and the quality of the image are influenced by the equipment selected and the technique used to obtain an x-ray image. This session will deal with the effect on patient dose, while the next session, Factors Affecting Image Quality (300-0701), will deal with the effect on image quality.


By the end of this session you will be able to:
• Distinguish between entrance surface dose (ESD) and effective dose in x-ray imaging
• Describe how the choice of x-ray receptor will affect dose
• Describe how the exposure factors selected will influence dose
