VMC++ accuracy and speed

❑ Sub-percent agreement with EGSnrc

❑ Is about 100 times faster than BEAMnrc for linac head simulations

❑ Is 50-150 times faster than EGS4/PRESTA for electron and photon beam simulations in the patient geometry for comparable accuracy.

❑ CPU times for in-patient simulations (10x10 beam, 5 mm voxels, 2% statistical uncertainty): o ~30 seconds for electrons
