Intensity-modulated radiation therapy (IMRT), one of the most important developments in radiation oncology in the past 25 years, involves technology to deliver radiation to tumors in the right location, quantity and time. Unavoidable irradiation of surrounding normal tissues is distributed so as to preserve their function. The achievements and future directions in the field are grouped in the three sections of the book, each suitable for supporting a teaching course. Part 1 contains topical reviews of the basic principles of IMRT, part 2 describes advanced techniques such as image-guided and biologically based approaches, and part 3 focuses on investigation of IMRT to improve outcome at various cancer sites.... quality assurance showing an average accuracy within 1mmon phantom studies, however, proper clinical confirmation is still required. ... to ac- quire the ultrasound images in the treatment room prior to treatment and the manual alignment of CT and ultrasound structures. ... and variability in the geometric relationship between the kV focal spot and the flat-panel detector attributed to flex in the detectoranbsp;...
