Patent number: 9696437Abstract: Improved X-ray detectors are provided in a cross-strip geometry with better resolution than the electrode spacing. The basic idea is analog charge cloud reconstruction. An important practical aspect of this work is rotating the electrode pattern by about 45 degrees relative to the detector slab, which provides several performance benefits (equal length for all electrodes and greater ease of integration into vertical stacks etc.) that are expected to be especially relevant to achieve high performance from analog charge cloud reconstruction.Type: GrantFiled: October 30, 2015Date of Patent: July 4, 2017Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Gabriella Carini, Sven Herrmann, Rebecca Fahrig

Patent number: 8331531Abstract: The present invention provides a radiotherapy treatment apparatus that includes a treatment beam, a magnetic field disposed parallel collinear to the treatment beam, and a target that is disposed along the treatment beam. The treatment beam can be a charged particle beam, a proton beam, an electron beam, or a linear accelerator (Linac) beam. The magnetic field is from a magnetic resonance imager (MRI), a megavolt x-ray imager, or a kilovolt x-ray imager and is disposed to operate in coordination with operation of the treatment beam and to narrow the beam. The tumor is disposed to rotate with respect to the treatment beam and the magnetic field, or the treatment beam and the magnetic field are disposed to rotate up to 360° with respect to the target when mounted to a ring gantry. The apparatus can include a rotation angle dependent shim disposed to account for Earth's magnetic field.Type: GrantFiled: March 15, 2010Date of Patent: December 11, 2012Assignees: The Board of Trustees of the Leland Stanford Junior University, The Regents of the University of CaliforniaInventors: Rebecca Fahrig, Norbert J.
