摘要：
Systems and methods for providing radiosurgery treatment to a patient by combining methods from both traditional radiosurgery and radiotherapy are disclosed. A dose sufficient to kill tissue is applied to a target area while a steep drop off, or gradient, is provided at the border between the target area and adjacent areas so that other portions of the brain or nearby structures or organs are not damaged. The treatment plan is optimized by using both measures known in the art along with a new gradient index or curve that indicates the amount of the drop off at the border between the target area and the surrounding tissues.
