Abstract: Systems, methods, and other embodiments associated with Tomosurgery are described. One method embodiment includes logically dividing a target volume into treatment slices to be radiated individually by co-planar beams. The method embodiment also includes planning a two dimensional path for moving a shaped isocenter through a treatment slice where the isocenter is produced by the intersection of the co-planar beams. The method embodiment also includes planning a three dimensional path for moving the shaped isocenter through the target volume based, at least in part, on two dimensional paths. The method provides a signal to control a radio surgery device to deliver radiation using the coplanar beams to the target volume based, at least in part, on the three dimensional path.

Abstract: A surgeon can select an entry point and a target point in a preoperative image volume of the patient. The target point and entry point form a trajectory line along which the surgeon wishes to perform a surgical procedure such as a biopsy and line up a surgical instrument. Once a surgical platform is moved along a guide arm arc close to a point on the trajectory line, the surgical platform is locked to the guiding arm. A pivot point position at the center of a ball joint in the middle of a metal plate is then arranged to be exactly at a point on the trajectory line. The metal plate is locked down and the ball joint is rotated to ensure that the surgical sleeve extends exactly along the trajectory line. This allows a decoupling between the position and orientation movements required to line the surgical sleeve up with the trajectory line to perform a surgical procedure. An interoperative localization device (ILD) is used to track the position of the surgical guide relative to the image space.
