DOSIMETRY ERROR REDUCTION FOR OPTIMIZED STATIC INTENSITY MODULATION

摘要

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