Abstract: An electron generating assembly for an x-ray tube has a thermionic cathode and an electrode system for accelerating electrons emitted by the thermionic cathode, and an electron multiplier disposed in the electron path. In order to achieve a given electron beam density, the electron beam current emitted by the cathode can be reduced dependent on the multiplication factor of the electron multiplier, thereby extending the service life of the overall assembly. The electron multiplier can be controllable.

Abstract: A miniature flat panel image intensifier display tube having an array of ctrically isolated parallel photocathode array stripes adjacent and orthogonal to a microchannel plate input electrode array comprising electrically isolated parallel metallic stripes. A video picture signal generator modulates a radiation source that causes a generally uniform flow of photons to impinge on the photocathode array. The photoelectrons that are emitted from the photocathode array are selectively accelerated into a charge pattern according to differential voltages scanned across both arrays by array switching electronic means wherein the charge pattern is converted to a visible image for viewing by an observer.

The housing encloses an electron beam source (22), and has elements for generating an electron beam along a beam path. The power supply (12A) is programmable to control the voltage, current and timing of an electron beam. The elongated tubular probe (14) extends along a central axis from the housing (12) about the beam path. The target assembly (26) extends along the central axis and is adapted for coupling to end of the probe (14) distal from the housing (12). The target assembly (26) includes target element (26A) positioned along the beam path, wherein the target element (26A) is adapted to emit x-rays in a predetermined spectral range in response to incident electrons. The beam steering assembly (29) includes a deflection element (30), a feedback network (31) and a deflection controller (144). The deflection element (30) deflects the beam from a nominal axis to a selected surface region on the target element (26) in response to a deflection control signal. The feedback network (31) includes deflection sensing elements for sensing the deflection of the beam and elements for generating a feedback signal representative thereof.

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.
