  • Patent number: 11672491
    Abstract: Validation of a therapeutic radiation treatment involves using an applicator balloon surrounding an X-ray radiation source to support a plurality of X-ray sensor elements (XRSE). The XRSE are supported on the applicator balloon at distributed locations to sense applied radiation from the radiation source. At least one parameter of the applied radiation which has been sensed by the XRSE is compared to a corresponding parameter of a predetermined radiation treatment plan. Based on the comparing, a determination is made as to whether one or more requirements of the predetermined radiation treatment plan have been satisfied.

  • Publication number: 20230178324
    Abstract: X-ray target element is comprised of a planar wafer. The planar wafer element includes a target layer and a substrate layer. The target layer is comprised of an element having a relatively high atomic number and the substrate layer is comprised of diamond. The substrate layer is configured to support the target layer and facilitate transfer of thermal energy away from the target layer.

  • Patent number: 10607802
    Abstract: Three dimensional beam forming X-ray source includes an electron beam generator (EBG) to generate an electron beam. A target element is disposed a predetermined distance from the EBG and positioned to intercept the electron beam. The target element is responsive to the electron beam to generate X-ray radiation. A beam former is disposed proximate to the target element and comprised of a material which interacts with the X-ray radiation to form an X-ray beam. An EBG control system controls at least one of a beam pattern and a direction of the X-ray beam by selectively varying a location where the electron beam intersects the target element to control an interaction of the X-ray radiation with the beam-former.

  • Patent number: 7005664
    Abstract: Methods and device are provided for improved storage screen readout. In one embodiment, a storage screen readout device comprises a first wavelength source and a second wavelength source, means of collecting phosphorescence stimulated by the sources, and means of effecting relative motion between the sources and the screen in order to obtain image information. The first wavelength may be selected to pump signal on the screen to be more easily readout by said second wavelength source. The sources may direct energy sequentially onto the screen, simultaneously onto the screen, any combination of the two, or combinations with other sources.

  • Publication number: 20030042445
    Abstract: An apparatus is provided for reading a latent image stored on a storage layer radiation screen, the apparatus comprising: a light source adapted to provide excitation light across a width of a storage layer radiation screen; and an excitation and image acquisition station comprising a mechanism for shaping the excitation light as an elongated region of excitation light across the width of the screen, optics for collecting a region of light emitted by a lateral strip of the screen excited by the elongated region of excitation light, and an elongated pixelated sensor array positioned to capture from the optics the region of light emitted by the screen; wherein the latent image stored on the screen is read by collecting and capturing light emitted from the screen as the screen moves past the excitation and image acquisition station.

  • Patent number: 6510197
    Abstract: A method and apparatus for forming and reading a radiation image of an object is provided. The method is performed by placing an object of which a radiation image is to be taken adjacent a platform that is positioned between a storage layer radiation screen and an electromagnetic wave radiation source such that radiation from the electromagnetic wave radiation source which traverses the object is absorbed by the storage layer radiation screen; forming a latent radiation image of the object on the storage layer radiation screen by causing the electromagnetic wave radiation source to emit radiation, a portion of the emitted radiation traversing the object and being absorbed by the storage layer radiation screen; and reading the latent radiation image of the object from the storage layer radiation screen.
