❑ 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 reduction 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
