Abstract

Detailed modeling of photon and electron transport is advantageous in radiotherapy and dosimetry. MultiTrans radiation transport code is based on tree multigrid technique and SP₃ approximation. The standard SP₃ approximation has been extended into a form that takes into account anisotropic group-to-group scattering. A first collision source method has been implemented. Applicability range of standard and extended SP₃ approximations in coupled photon-electron transport problems is examined by comparing calculated doses with deterministic MultiTrans and stochastic EGS4 radiation transport codes.
