WitrynaIntensity-modulated radiation therapy, or IMRT, is a type of cancer treatment that uses advanced computer programs to calculate and deliver radiation directly to cancer cells from different angles. It allows people with cancer to receive higher, more effective doses of radiation while limiting damage to the healthy tissues and organs around it. Witryna2 dni temu · However, radiotherapy is also associated with a wide spectrum of radiation-induced toxicities which reduces quality of life. 1 Technological advances, such as intensity modulated radiotherapy (IMRT), volumetric modulated arc therapy (VMAT), image guided radio therapy (IGRT) and intensity modulated proton therapy (IMPT) …

WitrynaThe treatment plans for IMRT and IMPT were both generated using the Treatment Planning System (TPS) of Eclipse (Varian Medical System, Inc., California, USA). The IMPT plans used two en-face beam angles and the IMPT with pencil beam weights was obtained through robust single-field optimization (SFO) technique. Witryna24 sty 2008 · In radiotherapy of NPC patients, three-field IMPT has greater potential than nine-field IMRT with respect to tumor coverage and reduction of the integral dose to OARs and non-specific normal tissues. The practicality of IMPT in NPC deserves further exploration when this technique becomes available on wider clinical scale. Background
