The Monte Carlo method is the most accurate method available for the calculation of absorbed dose and for simulating conditions that are often experimentally difficult (if not impossible) to verify. This technique uses random numbers to simulate the transport of radiation within an object of interest. It has many applications including modeling the radiation beams produced by linear accelerators.

The EGS4 and EGSnrc Monte Carlo code is being used widely within the Division of Medical Physics to study such diverse topics as Portal Imaging Dosimetry, the effects of 3D Conformal Electron Therapy and radiation transport for 3D Breast Imaging.
