WitrynaWhen compared to the tangential plans, SIB-IMRT maintained coverage (V95%) to the left breast and lumpectomy bed without significantly increasing the left breast maximum dose. SIB-IMRT was able to reduce the lung mean dose, maximum dose, and the V20 by 55–104 cGy, 983–1298 cGy (p < 0.001), and 3.7–4.4%, respectively. IMRT is a type of 3-D conformal radiation therapy. How it works. Like 3-D conformal radiation, radiation beams are aimed at the tumor from several directions. IMRT uses many more smaller beams than 3-D conformal and the strength of the beams in some areas can be changed to give higher doses to … Zobacz więcej Radiation beams used in external radiation therapy come from three types of particles: 1. photons 2. protons 3. electrons Zobacz więcej There are many types of external beam radiation therapy, all of which share the goal of delivering the highest prescribed dose of radiation to the tumor while sparing the normal tissue around it. Each type relies on a … Zobacz więcej

We hypothesized that PSPT exposes less lung tissue to radiation than IMRT and thereby …

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.
