Abstract

The relationship between the tissue–phantom ratio and central axis percentage depth dose data is derived. Relationships between the tissue–phantom ratio, tissue maximum ratio, and tissue–air ratio are given. A simple model is developed which suggests that the degree to which the TPR and TMR are independent of distance from the source depends largely on the collimator/flattening filter scatter.
