Intensity modulated radiation therapy (IMRT) in the treatment of head-and-neck cancers has the
ability to minimize dose to normal structures. The highly conformal nature of IMRT places an
increased importance on knowledge of anatomical displacement over the course of treatment.
This is the preliminary analysis of a prospective study analyzing the degree of anatomic
displacement during a course of head-and-neck radiotherapy.
