October 22, 2021 —RaySearch Laboratories ABandMevion Medical Systems日前，两家质子治疗领域领先的公司宣布了一项合作，将与MEVION S250i质子治疗系统一起开发用于FLASH传输的先进治疗计划技术。
The collaboration will exploreFLASH intensity modulated proton therapy(IMPT) delivery using a technique that supports the delivery of large-volume clinical FLASH fields through the combination of smaller fields, each delivered at FLASH dose rates which complements Mevion’s advanced Hyperscan delivery system.
Townsend Zwart, Vice President of Advanced Development, Mevion Medical Systems, says: “Mevion is pleased to continue our long partnership with RaySearch to develop ultra-high dose rate (FLASH) intensity modulated proton therapy. Optimizing FLASH delivery requires explicit consideration of the time dependent dose delivery and sequencing of proton spots. Overlapping spots or spots with multiple pulses may have complex FLASH weighting factors. Differing tissue types or tissue properties may also need to be included in an effective dose weighting model. The RaySearch development team is uniquely qualified to incorporate these features into a FLASH dose calculation module.”
Kjell Eriksson, Chief Science Officer, RaySearch, says: “RayStation already supports IMPT planning for Mevion’s Hyperscan system with Monte Carlo dose calculation for both optimization and final dose calculation. We are now excited to explore how RayStation can create optimal FLASH plans for the Hyperscan system and to further deepening our partnership.”
Since 2014, RaySearch and Mevion have collaborated to provide advanced treatment planning capabilities for Mevion’s HYPERSCAN pencil-beam scanning and Adaptive Aperture pMLC. Both companies will be exhibiting at the upcomingAmerican Society for Radiation Oncology(ASTRO) annual meeting in Chicago, October 24–26. Attendees are invited to the respective booths to learn more.
* FLASH therapy is currently under preclinical research and is not yet available for commercial sale or clinical use.
