Patent ID: 7616735

Claim:
A computer-implemented method, comprising: logically dividing a target volume into two or more treatment slices to be radiated individually by radiation delivered by co-planar beams; planning a two dimensional path for moving a shaped isocenter through a treatment slice, the two dimensional path to include a set of scan points to be visited by the isocenter, the isocenter to be produced by the intersection of the co-planar beams, and where planning a first two dimensional path through a first treatment slice can begin before a second treatment slice has been defined; planning a three dimensional path for moving the shaped isocenter through the target volume based) at least in part, on two or more of the two dimensional paths; and providing a signal to control a radiosurgery device to deliver radiation using the coplanar beams to the target volume based, at least in part, on the three dimensional path.
