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.
