What is the advantage of shaped beam radiosurgery?
Traditionally, circular beams are used for radiosurgery. The resulting dose of such an approach is a spherical dose volume. As most lesions are very irregular in shape, several of those spherical dose volumes have to be composed together to cover the complex tumor shape. Other systems try to move the circular beam to “paint” the dose into the tumor volume over a time. Both approaches are time consuming and do not ideally tailor the dose to the exact shape of the tumor. This can result in lower than desired irradiation to parts of the tumor and higher than desired irradiation to healthy tissue. Novalis Tx has set a new standard with the most precise beam shaping technology available, shaping each treatment beam to contour the exact shape of the tumor and avoiding normal tissue with highly accurate and homogeneous doses.
