Publication number: 20230372737Abstract: A motion-enable device includes a mechanical switch and a capacitive sensor with a sensing region that is located adjacent to the mechanical switch. The mechanical switch enables a first signal when closed or actuated that indicates that the mechanical switch is in an active state. The capacitive sensor enables a second signal when a conductive object is disposed in the sensing region, where the second signal indicates that the capacitive sensor is in an active state. Enablement of operation of an apparatus depends on receipt of both the first signal and the second signal. The mechanical switch and the capacitive sensor act as the two separate switches required by functional safety requirements for a motion enable device. Because the sensing region of the capacitive sensor is adjacent to the mechanical switch, the first and second signals are generated when an operator actuates the mechanical switch with a single digit.Type: ApplicationFiled: July 31, 2023Publication date: November 23, 2023Applicant: Varian Medical Systems, Inc.Inventors: Ross HANNIBAL, Wade CURTISS

Patent number: 11786758Abstract: A radiation dose received by a patient from a radiation therapy system can be verified by acquiring a cine stream of image frames from an electronic portal imaging device (EPID) that is arranged to detect radiation exiting the patient during irradiation. The cine stream of EPID image frames can be processed in real-time to form exit images providing absolute dose measurements at the EPID (dose-to-water values), which is representative of the characteristics of the radiation received by the patient. Compliance with predetermined characteristics for the field can be determined during treatment by periodically comparing the absolute dose measurements with the predetermined characteristics, which can include a predicted total dose in the field after full treatment and/or a complete irradiation area outline (CIAO). The system operator can be alerted or the irradiation automatically stopped when non-compliance is detected.Type: GrantFiled: May 26, 2021Date of Patent: October 17, 2023Assignees: SIEMENS HEALTHINEERS INTERNATIONAL AG, VARIAN MEDICAL SYSTEMS, INC.Inventors: Christof Baltes, Todd Holmes

Patent number: 11771388Abstract: A system can have an x-ray source that generates a series of individual x-ray pulses for multi-energy imaging. A first x-ray pulse can have a first energy level and a subsequent second x-ray pulse in the series can have a second energy level different from the first energy level. An x-ray imager can receive the x-rays from the x-ray source and can detect the received x-rays for image generation. A generator interface box (GIB) controls the x-ray source to provide the series of individual x-ray pulses and synchronizes detection by the x-ray imager with generation of the individual x-ray pulses. The GIB can control x-ray pulse generation and synchronization to optimize image generation while minimizing unnecessary x-ray irradiation.Type: GrantFiled: February 6, 2023Date of Patent: October 3, 2023Assignee: VARIAN MEDICAL SYSTEMS, INC.Inventors: Arundhuti Ganguly, Gary F.
