Imrt photon radiation
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. Witrynawith IMRT and conventional external-beam approaches for prostate cancer and calculated a maximum risk of fatal sec-ond malignancy of 1.7% for conventional …

WitrynaWhile proton radiation therapy offers substantially better dose distribution characteristics than photon radiation therapy in certain clinical applications, data demonstrating a quantifiable clinical advantage is still needed for many treatment sites. Unfortunately, the number of patients treated with proton radiation therapy is still comparatively small, in … Witryna11 lis 2024 · Key Points. Question Compared with intensity-modulated radiation therapy (IMRT), is intensity-modulated proton therapy (IMPT) associated with fewer toxic effects and comparable oncologic outcomes among patients with oropharyngeal carcinoma (OPC)?.
