Abstract
A radiation therapy delivery and dosimetry error correction system. Rather than iteratively creating more segments to correct for dosimetry errors, the present invention receives the outputs from a segment optimization algorithm (i.e., a set of segments and an initial set of monitor units) and varies the number of monitor units associated with each segment to correct for dosimetry errors. Only if an extreme case exists will additional segments be added.
