The present invention includes a method of pre-planning a spherical fixed point stereotactic radiosurgery by obtaining an image from a patient having a target, the image comprising coordinates of the actual patient target in 3 dimensions on a first day planning an optimal stereotactic radiosurgery using the patients actual target using actual coordinates in 3 dimensions prior to the day of surgery by creating virtual radiosurgical coordinates and plans to maximize target exposure and minimize the patients waiting time in radiosurgery, thereby allowing evaluation of several plans to maximize plan conformality and safety and treating the patient based on the virtual stereotactic radiosurgery plans on a second day.
