Baymouth MLC Test

Description

This test will detect the position of each leaf (not just the pair of leaves) for accuracy.

Based on the paper "MLC quality assurance techniques for IMRT applications”, J. E. Bayouth, et al., Med. Phys 30 (5) May 2003 pp. 743-750

The leaf positions are measured from the central axis and a graphical display is created to indicate which leaves are out of their expected position and which exceed tolerances established by the user.
