Varian, a Siemens Healthineers company, said it received 510(k) clearance from the FDA for TrueBeam and Edge radiotherapy systems featuring HyperSight imaging solution.
HyperSight imaging allows clinicians to acquire images during a patient's daily course of radiation treatments. The image quality is designed to improve the ability to target tumor volumes more precisely and spare healthy tissue for patients receiving radiation therapy treatments. With the addition of HyperSight, linear accelerators across the Varian portfolio can now produce images that deliver the Hounsfield Unit (HU) accuracy necessary for treatment planning directly on the acquired conebeam CT (CBCT) images. As a result, this technology can be used for offline adaptive planning to adjust for anatomical changes to the tumor and surrounding organs over the course of treatment without the need for an additional trip to a separate CT scanner.
HyperSight on TrueBeam and Edge acquires images for all anatomical sites with a 50% faster gantry rotation, significantly reducing acquisition time. In contrast, traditional CBCT scans can take up to 60 seconds, depending on the anatomical site being scanned. A reduction in CBCT acquisition time reduces motion-related artifacts due to patient movement. A shorter image acquisition time may minimize patient discomfort and anxiety due to less time on the treatment table.
Initially launched in 2022 on Varian's Ethos and Halcyon therapy systems, HyperSight has been gaining popularity among clinicians and researchers alike. With nine studies either conducted, in progress, or to be initiated across eight institutions, Varian is committed to better understanding the role HyperSight may play in advancing care and enhancing the patient experience. The customer-led Intelligent Imaging Consortium, created by Varian, offers HyperSight users a forum to collaborate and innovate on trials and studies.
