Patent ID: 8654923

Claim:
A system for developing a dynamic radiosurgery plan to eradicate a tumor volume located in any anatomical site other than the breast area using dose volume painting and an optimal path of travel, such that each point of the tumor volume is covered by the dose volume during the path of travel, the system comprising a Gamma Knife radiation delivery system, a microprocessor, a memory and a program, said program residing in said memory and said microprocessor being configured to execute the program, said program comprising a planning algorithm, wherein said planning algorithm comprises the steps of: (a) imposing a 3D grid structure underlying the tumor volume to obtain an underlying grid structure; (b) determining a set of intersections on the underlying grid structure that must be traversed by dose shots to cover the tumor volume; (c) shifting the underlying grid structure to minimize the set of intersections to improve quality and duration of a final route of the dynamic radiosurgery plan; (d) generating an initial set of potential dose shots; (e) optimizing the initial set of potential dose shots and selecting a subset of dose shots; (f) calculating a path for the locations of the subset of dose shots; (g) producing the dynamic radiosurgery plan based on the path for the locations of the subset of dose shots; and (h) performing a final dose calculation on the path using fine interpolations.
