Modeling of asymmetric compensator geometries.
Dose distributions arising from the use of near unit density retracted missing tissue compensators in symmetric geometries have been successfully modeled on the basis of primary and first-order scattered radiation. This method of analysis has been extended to both low- and high-density materials in asymmetric geometries. Good agreement is achieved between theory and experiment.
