AbstractA method of treating brain tumors in a patient, comprising the steps of: identifying and locating a brain tumor in vivo by affixing a stereotactic frame to the head of the patient, performing a computer tomographic (CT) scan of the skull of the patient to determine the location, size, and shape of the tumor with respect to the stereotactic frame, performing a biopsy by inserting an extraction tool along a path measured with respect to the frame to the tumor location, extracting a tissue from the location, removing the needle and the extracted tissue and analyzing the tissue; implanting at least a portion of an adjustable x-ray radiation source in the patient proximate the tumor, the adjustable radiation source including an electron beam source outside the head of the patient, and directing an electron beam produced by the source outside the head of the patient along the path to the location; and controlling the source to generate an x-ray radiation pattern characterized by a spatial and temporal distribution, to selectively irradiate the tumor.
