Publication number: 20230271031Abstract: A radiation therapy system includes an X-ray imaging system that is configured with a combined and simplified filter and collimator positioning mechanism. In addition, an X-ray imager of the RT system is only positioned at a few discrete locations within a plane that is a fixed distance from the imaging X-ray source when generating X-ray images. As a result, for each of these discrete imaging positions, the simplified filter and collimator positioning mechanism positions a specific collimator-filter combination in a specific location between the X-ray source and the imager.Type: ApplicationFiled: May 5, 2023Publication date: August 31, 2023Applicant: SIEMENS HEALTHINEERS INTERNATIONAL AGInventor: Reto FILIBERTI

Patent number: 10973488Abstract: In an x-ray imaging method, the acquisition of a signal image is split off into acquisition of two or more subimages or frames. The first subimage may be acquired with an exposure of a low dose followed by a readout cycle. The dose of the exposure for acquiring the first subimage can be chosen such that it is below the default dose for a particular anatomy. The first subimage may be used to calculate or estimate the parameters of exposure for acquiring a second or subsequent images subimage. The estimation may be such that the total dose received by the imager, in acquiring the first and second subimages, achieves an expected target value to provide an image of good quality. The first and second subimages can be combined to form the final image. A detector array supporting automatic exposure control (AEC) includes AEC pixels providing AEC signals. The AEC pixels are independently or individually addressable and/or readable.Type: GrantFiled: April 24, 2019Date of Patent: April 13, 2021Assignee: Varian Medical Systems International AGInventors: Daniel Morf, Reto Filiberti

Patent number: 10646730Abstract: Collision free regions are predetermined for one or more class solutions. Each class solution has defined limits for allowed field geometry variations. Collision free regions in planning can be defined as a set of allowed isocenter positions relative to a fixation device. The collision free regions may be visualized by a user to plan for field geometry and isocenter position tradeoffs. Collision free regions in delivery can be defined as a set of allowed couch support coordinates. The treatment fields in a radiation treatment plan can be checked against the collision free regions in delivery to determine whether they will pose any collision risks.Type: GrantFiled: November 13, 2018Date of Patent: May 12, 2020Assignees: Varian Medical Systems International AG, Varian Medical Systems, Inc.Inventors: Janne Nord, Joakim Pyyry, Adam Harrington, Sean Herries, Joseph Schumm, Reto Filiberti, Kari Jyrkkälä, Sylvie Spiessens, Roland Meier, Dominique Gasser

Patent number: 10272265Abstract: An outline of at least a patient on a patient support is determined. Based on at least one image of the patient, a plurality of orientations of the patient support and of at least one device are determined. The at least one device is capable of delivering a radiation treatment to the patient or of performing imaging associated with the radiation treatment. Based on the outline and the plurality of orientations of the patient support and of the at least one device, a clearance zone that no portion of the at least one device will occupy when the at least one device or the patient supported by the patient support is in motion is calculated.Type: GrantFiled: April 1, 2016Date of Patent: April 30, 2019Assignee: VARIAN MEDICAL SYSTEMS INTERNATIONAL AGInventors: Reto Filiberti, Dominique Gasser
