ABSTRACT:
A method and apparatus for delivering optimized treatment plans to deliver relatively high doses of ionizing radiation to target tissues while minimizing dose to the surrounding healthy tissues. The present invention utilizes continuous gantry motion in which field shape, which is conformed with a multi-leaf collimator, changes during gantry rotation. Using multiple superimposing arcs, arbitrary two-dimensional beam intensity distribution at different beam angles can be delivered, giving arbitrary dose distribution in the patient to maximize the therapeutic ratio.
