7236568 Miniature x-ray source with improved output stability and voltage standoff June 26, 2007
An x-ray source includes an insulating tube having a cylindrical inside surface defining a cylindrical vacuum cavity, a cathode located near a first end of the insulating tube and adapted to be optically heated for emitting electrons, an anode adapted for a voltage bias with respect to
5528652 Method for treating brain tumors June 18, 1996
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
5442678 X-ray source with improved beam steering August 15, 1995
This invention is directed to an x-ray source comprising a housing, an elongated tubular probe, a target assembly, and a beam steering assembly. The housing encloses an electron beam source, and has elements for generating an electron beam along a beam path. The elongated tubular probe
5422926 X-ray source with shaped radiation pattern June 6, 1995
The present invention is directed to an x-ray source for irradiating a volume in accordance with a predetermined dose distribution. The source comprises a housing, an elongated tubular probe, and a target assembly. The housing encloses an electron beam source and includes elements for
5369679 Low power x-ray source with implantable probe for treatment of brain tumors November 29, 1994
An apparatus for treating a brain tumor in a patient, which includes an x-ray source of preselected or preprogrammed duration and intensity assembled in combination with a reference frame. The reference frame can be, for example, a stereotactic frame. The apparatus allows accurate po
5153900 Miniaturized low power x-ray source October 6, 1992
A low-level, electron beam activated source of preselected or programmable duration and intensity x-rays. The source may be fully or partially implanted into, or surface-mounted onto a desired area to affect a preselected irradiated region. In medical applications, a method of treati
