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) … Witryna(IMPT). Opened in 2006 as the first proton therapy center at a major comprehensive cancer center, it is now one of 10 proton therapy centers currently operating in the United States. The Proton Therapy Center treats over 800 patients of all ages every year. IMPT, considered the “holy grail” by many radiation oncologists, is best used to ...
