Motion detection system with three USB cameras and an active search algorithm for stereotactic radi may cause side effects to normal organs. This paper describes our motion detection system with three USB cameras. The motion detection of a patient was performed by tracking his/her ears and nose with three USB cameras, where a pattern matching between a predefined template image for each view and

Treatment Planning for Volumetric Modulated Arc Therapy (VMAT),ator (MLC) leaf position and dose rate vary continuously during delivery. A treatment planning system for VMAT is presented..Arc control points are created uniformly throughout one or more arcs. An iterative least-squares algorithm is used to generate a fluence profile at every control point. The co

The 21st Birthday Party for intensity-modulated radiation therapy (IMRT); 21 years from 1988-2009; atches the volumetric shape of the intended target region and simultaneously spares the nearby organs at risk. It is particularly competent for treating head-and-neck cancers, prostate, lung, breast and other targets where adjacent organs at risk are present. The development of IMRT is firmly rooted
