Patent number: 10406382Abstract: A radiation system includes a radiation source providing therapeutic radiation, a first gantry supporting a second gantry carrying the radiation source. The first gantry is rotatable about a first axis passing through an isocenter, thereby allowing the radiation source to aim therapeutic radiation at a target volume from a plurality of locations in a first plane. The second gantry carrying the radiation source is rotatable about a second axis passing through the isocenter non-parallel with the first axis, thereby allowing the radiation source to aim therapeutic radiation at the target volume from a plurality of locations in a second plane non-coplanar with the first plane.Type: GrantFiled: April 21, 2017Date of Patent: September 10, 2019Assignee: Varian Medical Systems, Inc.Inventors: David Humber, Josh Star-Lack, Stanley Mansfield, Ross Hannibal

Patent number: 7817774Abstract: The present invention provides a system 10 for irradiating a breast 20 of a patient 22. The system 10 comprises a gantry 12 rotatable about a horizontal axis 14 and comprising a radiation source 16 for generating a radiation beam 18 and a detector 24 spaced from the radiation source 16, and a barrier 26 disposed between the patient 22 and the gantry 12. The barrier 26 is provided with an opening 30 adapted to allow a breast 20 passing therethrough to be exposed to the radiation beam 18. In some embodiments, the barrier 26 is provided with an opening 30 adapted to allow both the breast 20 and the tissue leading from the breast to axilla and the muscle tissue of the adjacent chest wall passing therethrough to be exposed to the radiation beam 18.Type: GrantFiled: September 9, 2008Date of Patent: October 19, 2010Assignee: Varian Medical Systems, Inc.Inventors: Larry D. Partain, David Humber

Patent number: 7539286Abstract: A filament assembly for use in an x-ray emitting device or other filament-containing device is disclosed. In one embodiment, an x-ray tube is disclosed, including a vacuum enclosure that houses both an anode having a target surface, and a cathode positioned with respect to the anode. The cathode includes a filament assembly for emitting a beam of electrons during tube operation. The filament assembly comprises a heat sink and a plurality of filament segments. The filament segments are configured for simultaneous emission of an electron beam for impingement on the target surface of the anode, and are electrically connected in series. Each filament segment includes first and second end portions that are thermally connected to the heat sink, and a central portion that can be configured with a modified work function for preferential electron emission.Type: GrantFiled: November 19, 2007Date of Patent: May 26, 2009Assignee: Varian Medical Systems, Inc.Inventors: Steve Bandy, Gary F Virshup, Michael Curzon Green, James Russell Boye, Dennis Runnoe, Robert Clark Treseder, David Humber
