VMC++

VMC was developed by I. Kawrakow, M. Fippel and K. Friedrich

with K. Ulm at the U of Leipzig, 1996

o

VMC originally only for electrons

o

Extended later by M.Fippel to photons - xVMC

o

Re-implemented in C++ by I. Kawrakow at NRC - VMC++

Recent work implements a series of additional variance reduaction

techniques for photons to gain in calculation time

o

Exact MS theory developed at NRC

o

Boundary crossing algorithm (BCA) allowing multi-voxel CH steps

o

Optimization of sampling algorithms

Generated with emphasis on filling the multidimensional space of

interest in as uniform a way as possible

Used in Elekta Monaco
