Abstract
A method of treating brain tumors in a patient, comprising the steps of: identifying and locating a brain tumor in vivo; implanting at least a portion of an adjustable x-ray source in the patient proximate to the tumor, where the x-ray source generates an electron beam along a path on or slightly offset from a central axis to an x-ray emitting target element; and controlling the x-ray source to generate an x-ray pattern to selectively irradiate the tumor. Also disclosed is a method and apparatus for detecting certain x-ray photons generated by the x-ray source and propagating back on a path which is along or slightly off-set from the central axis of the implanted radiation source.
