A METHOD WHICH PROVIDES LOCATION INFORMATION OF THE LEKSELL FRAME BEFORE THE GAMMA KNIFE RADIOSURGERY

摘要

The present invention, is located the head of the equipped with a stereotactic assembly 40 patients in the helmet 10 of the gamma knife radiosurgery apparatus 1 and the distribution in the gamma knife radiosurgery apparatus 1, a plurality of radioactive material provided in the by irradiation of radiation emitted from the crew 24 via the collimation hole (13) of the helmet gamma knife radiosurgery for treating lesions in the brain of a person placed on the position where the radiation to focus, gamma knife radiosurgery a method for providing location information around the stereotactic apparatus, the orientation mechanism (40) inside the helmet (10) of the orientation mechanism (40) for generating a region in a two-dimensional plane and the gamma knife radiosurgery apparatus 1 is moving by being radiosurgery this step, the orientation mechanism for brain imaging of patients indicated in the image on the plane perpendicular to the key direction of the patient to generate two-dimensionally as a possibly fictitious treatment area in the region of the orientation mechanism the extent to which the step of overlapping the region and the treatment area, at least one lesion that determining that exists within the treatment area, when the lesion shown in the brain images are not present in the treatment area has all of the lesion shown in the brain imaging are for the localization mechanism region of the brain image when moving the brain imaging until the position in the treatment area in the orientation mechanism area, and all the lesions displayed on the brain images are present in the treatment area and a step of calculating the relative position information. Further, the present invention may be able to calculate the optimum orientation mechanism installed position by implementing a localization mechanism (40), a helmet (10) and brain imaging 3D graphics correlations. According to the present invention, there are actually benefits of the information about the information and procedures on the optimal availability of the installation position by a stereotactic apparatus also MRI image or a CT image without looking to the mounting mechanism to orient the head. ; Gamma knife radiation, brain imaging, stereotactic instruments, reksel frame, MRI, helmets, cobalt-60, a brain tumor, the automatic mode, manual mode
