WitrynaIMRT makes it relatively easy to specify different doses to each of the PTVs. The organs at risk (OARs), or critical normal structures, are tissues, which, if irradiated, could suffer significant morbidity and, thus, might influence the treatment planning and/or the dose prescription. In principle, all nontarget tissues could be OARs.
