title: Beam modeling for a convolution/superposition-based treatment planning system.
abstract: The basic relationships of the convolution/superposition dose calculation technique are reviewed, and a modeling technique is described that can be used to obtain a satisfactory beam model for a commercially available convolution/superposition-based treatment planning system. The objective of beam modeling is to build a model of the primary fluence that is incident on the patient which can then be used in the calculation of the dose deposited in the patient, by using the convolution superposition method.
