WitrynaIMRT and PBT aim to deliver most of the radiation to the prostate cancer while sparing surrounding tissues. Both IMRT and PBT have been used in the treatment of prostate cancer and are thought to be equally effective at curing prostate cancer.

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. hovercam pilot 3 wireless digital podiumWitrynaVolumetric modulated arc therapy uses photons (X-rays) generated by a medical linear accelerator.
