Patent number: 8299448Abstract: A control parameter is determined for a system for irradiating a predetermined target volume in a body with a particle beam. The system is constructed to direct the particle beam at a multiplicity of target points in the target volume in succession in order to produce at, each of the target points a predetermined dose distribution in a region around the target point. The control parameter controls the extent of an overlap of the dose distribution of a first target point with the dose distributions of neighboring target points. For determination of the control parameter, there is first determined a movement parameter which quantitatively characterizes the movement of the body at the first target point. The control parameter is determined in dependence on the movement parameter.Type: GrantFiled: February 19, 2008Date of Patent: October 30, 2012Assignees: GSI Helmholtzzentrum fuer Schwerionenforschung GmbH, Siemens AGInventors: Christoph Bert, Eike Rietzel, Gerhard Kraft

Patent number: 8294116Abstract: Optical beam modulation is accomplished with the aid of a semiconductive nanomembrane, such as a silicon nanomembrane. A photocathode modulates a beam of charged particles that flow between the carbon nanotube emitter and the anode. A light source, or other source of electromagnetic radiation, supplies electromagnetic radiation that modulates the beam of charged particles. The beam of charged particles may be electrons, ions, or other charged particles. The electromagnetic radiation penetrates a silicon dioxide layer to reach the nanomembrane and varies the amount of available charge carriers within the nanomembrane, thereby changing the resistance of the nanomembrane. As the resistance of the nanomembrane changes, the amount of current flowing through the beam may also change.Type: GrantFiled: September 11, 2009Date of Patent: October 23, 2012Assignee: Applied Nanotech Holdings, Inc.Inventors: Nan Jiang, Richard Lee Fink

Patent number: 8148703Abstract: An apparatus is provided for determining and monitoring parameters of a radiation treatment. The apparatus produces a first image of a region of a patient body to be radiated using a medical imaging process, determines a parameter setting of a radiation system using the first image, and provides the radiation treatment to the body region to be radiated using the radiation system with the determined parameter setting. The apparatus further produces a second image of the body region radiated with the parameter setting, automatically comparing the first image and the second image, and generates a deviation signal when a difference between the first image and the second image exceeds a predetermined threshold value.Type: GrantFiled: May 17, 2010Date of Patent: April 3, 2012Assignee: Siemens AktiengesellschaftInventor: Andres Sommer
