“…Acceptance of IMRT has been based on data from retrospective studies that showed improvement in local control while maintaining target coverage and simultaneously minimizing the side effects by means of sparing organs at risk (OARs), particularly the rectum [1,3,4].

IMRT requires increased departmental resources through increased treatment planning times and increased physics quality assurance.…”
