Multiple scattering of electrons as a compound Poisson process
Abstract
Electron beam therapy has the distinct advantage in the treatment for certain cancers. But the calculations of dose distribution for electron beams are difficult because of electron's redistribution caused by multiple scattering of the electron penetrating tissue. In this study a method is developed for the calculation of angular probability density distribution of multiply scattered electrons. The method (CPP method) has been developed based on a compound Poisson process model of multiple angular scattering for charged particles. The CPP method provides an accurate algorithm that can be incorporated into electron beam dose calculation.
