Abstract:
1. A method of pre-planning a stereotactic radiosurgery comprising: obtaining one or more images from a patient having a target; adding a stereotactic frame in silico to the one or more images; identifying a center slice in the image to define an intermediate slice of stereotactic space that comprises, optionally, a maximum anterior-posterior and lateral diameter; selecting three or more points from the one or more images containing the target, wherein the three or more points comprise vertices of a right triangle with sides equal to half of the distance between a plurality of fiducial markers and the center of the stereotactic frame; matching the distances between the fiducial markers and the stereotactic frame; measuring the length, width and distance to a skull vertex in the previously selected intermediate slice image and using a parametric formula to calculate a skull radii; and planning an optimal stereotactic radiosurgery using the patient's actual target using actual coordinates in 3 dimensions prior to the day of surgery by creating several virtual radiosurgical coordinates and plans, thereby allowing evaluation of several plans to optimize conformality and safety.
