Abstract

Stereotactic radiosurgery is the precise application of high dose radiation to cranial lesions. A combination of isocenters or `shots' is utilized by the physician to map the contours of the target lesion. This pattern of shots results in a high dose of radiation to the lesion while delivering a lesser, non-lethal dose to healthy tissue elsewhere in the brain. In an effort to improve the efficacy and efficiency of stereotactic treatment planning, a method for the automatic correlation of the intrinsic data sets has been developed. Individual coordinate transforms for each of the data sets are calculated using a coordinate system provided by a stereotactic frame fixed to the patient's skull. Each data set is then correlated within this common coordinate system. Through the use of multiple, cascaded coordinate transforms the accuracy of the correlated display is maximized. Each data set is displayed on its own graphical layer allowing the physician to visualize any combination of the individual data sets.
