Stereotactic body radiation therapy
SBRT is a treatment procedure similar to brain stereotactic radiosurgery and radiotherapy, except it deals with tumors outside the brain. It involves a single high dose radiation delivery or a few fractionated radiation deliveries (called hypofractionated radiation therapy). The procedure will reduce the treatment time for some early stage tumors, especially oligometastases in lung, liver, and bone from multiple weeks to single or a few days. The challenge of this process is that the high precision device used for brain immobilization is not feasible for body components because they are not only non-rigid but also associated with substantial organ motion. Duke has been actively engaged on the development of new techniques to implement best available methods to immobilize patient, localize treatment target and monitor the radiation treatment for SBRT.
