Title: Catheterized plasma X-ray source

Abstract

A radiation generator useful for medical applications, among others, is provided. The radiation generator includes a catheter; a plasma discharge chamber situated within a terminal portion of the catheter, a cathode and an anode positioned within the plasma discharge chamber and separated by a gap, and a high-voltage transmission line extensive through the interior of the catheter and terminating on the cathode and anode so as to deliver, in operation, one or more voltage pulses across the gap.

  • This patent describes a plasma-generated X- ray source. It comprises a laser pulse generator for making a template laser pulse, the template laser pulse having a time duration equal to a first time period; a laser amplifier medium having an excited region which is excited for a time duration equal to a second time period wherein the second time period is longer than the first time period, such that when the template pulse propagates in the excited region of the medium, energy is transferred from the laser medium to the template pulse thereby increasing the energy of the template pulsemore » producing an amplified template pulse having a time duration substantially equal to the first time period; and an optical transport system for delivering the amplified template pulse to a target material causing the target material to form a plasma from which X-rays are emitted.« less
  • A device for fabricating a target of a lasing material and a pump material for lasing at X-ray wavelengths wherein one of the materials occurs naturally as a gas. A substrate of the other material is cooled below the freezing point of the one material occuring naturally as a gas. Then a gaseous atmosphere of the latter material is supplied to the cooled substrate so that a frozen layer of the latter material condenses onto the substrate to form the target.

  • In an exemplary arrangement a rotatable scanning system comprises an x-ray tube which emits a beam of x-rays which penetrates the layer to be examined, and a radiation receiver which supplies electrical output signals corresponding to the measured radiation intensity. A computer is connected to the radiation receiver for calculating the attenuation values of specific image points of the irradiated body layer from the output signals of the radiation receiver. An inductive transformer is provided for transmitting energy to the x-ray tube , its secondary winding being arranged in a fixed position relative to the x-ray tube and rotating withmore » the scanning system and its primary winding being fixed relative to the stationary part of the unit.« less
  • A vacuum ultraviolet and x-ray light source based on spontaneous anti-stokes scattering from atomic population stored in a metastable level is described. The source has a maximum brightness, attained as the media approaches two-photon opacity, equal to that of a blackbody at a boltzmann temperature characteristic of the population of the metastable level. The source may have high resolution, picosecond time scale, and on a pulsed basis is brighter than other laboratory vacuum ultraviolet light sources. Short wavelength lasers pumped by said source are also described. The lasing atomic species can be separate from or combined in the same envelopemore » with the light source atomic species. Use of the source for spectrographic applications is also described.« less
