1. A method for quality assurance testing of a linear accelerator (LINAC), said method comprising:
utilizing a reference machine with standardized parameters, said reference machine comprising said LINAC and an electronic portal image device (EPID);
adjusting parameters of said LINAC of said reference machine and performing radiation operations with said LINAC of said reference machine;
collecting, based on said radiation operations, radiation measurement data from said EPID of said reference machine;
collecting reference data of said reference machine, said reference data representing differences in radiation measurements at said EPID of said reference machine relative to any changes to said parameters of said LINAC of said reference machine;
storing said reference data in a memory associated with at least one processor associated with said reference machine; and
analyzing said reference data via a software analysis program associated with said processor, said processor being configured to execute said software analysis program.
