Publication number: 20230241415Abstract: A photon source emits a flattening filter-free photon beam. A control circuit operably couples to a multi-layer multi-leaf collimator that is disposed between the photon source and a treatment area of a patient. The control circuit automatically arranges operation of some, but not all, of the layers of the multi-layer multi-leaf collimator to serve as a virtual flattening filter with respect to the flattening filter-free photon beam emitted by the photon source. By one approach, another of the layers of the multi-layer multi-leaf collimator serves to form a treatment aperture corresponding to a shape of the treatment area of the patient. By one approach the control circuit comprises an integral part of a treatment platform (as versus a dedicated treatment planning platform) and can carry out most or even essentially all of the planning steps that lead to administration of the treatment to a patient.Type: ApplicationFiled: April 12, 2023Publication date: August 3, 2023Inventors: Mika Miettinen, Ross B. Hannibal, Mu Young Lee

Publication number: 20220280812Abstract: An apparatus includes a first multileaf collimator comprising a plurality of pairs of beam-blocking leaves each comprising an end portion. The end portions of the beam-blocking leaves of one pair are contoured to allow forming a first aperture when the beam-blocking leaves of the pair are closed. The first aperture has a closed shape such as a circle in a beam's eye view.Type: ApplicationFiled: March 8, 2021Publication date: September 8, 2022Inventors: Ross B.

Patent number: 9974494Abstract: A radiation system includes a radiation source having an accelerator, the radiation source having a magnetic field associated therewith that is resulted from an operation of the accelerator, and a magnetic field source configured to provide a compensating magnetic field to at least partially counteract against the magnetic field that is resulted from the operation of the accelerator. A radiation system includes a radiation device having a radiation source, a patient support, and a protective guard located between the radiation source and the patient support, wherein the protective guard is moveably coupled to the radiation device or the patient support. A radiation system includes a particle generator for generating a particle, an accelerator for accelerating the particle, and a magnetic source for changing a trajectory of the particle, wherein the magnetic source comprises a permanent magnet.Type: GrantFiled: June 21, 2016Date of Patent: May 22, 2018Assignee: VARIAN MEDICAL SYSTEMS, INC.Inventors: Hassan Mostafavi, Marcel R. Marc, Stanley Mansfield, Raymond D. McIntyre, Ross B. Hannibal

Patent number: 8730314Abstract: A method of monitoring radiation treatment employs a video camera directed to at least a portion of a patient and/or patient support and at least a portion of a radiation machine. The direction of movement of the radiation machine and/or clearance between at least a portion of the radiation machine and the patient are determined by a control system. Graphics indicating the direction of movement of the machine and/or the clearance between the machine and the patient are overlaid on the video images. The video images overlaid with graphics displayed on a display.Type: GrantFiled: August 25, 2010Date of Patent: May 20, 2014Assignee: Varian Medical Systems, Inc.Inventors: Ross B.
