Varian, a Siemens Healthineers company, has gained U.S. Food and Drug Administration (FDA) 510(k) clearance for new functionality to its Ethos radiotherapy system.

西门子Healthineers公司瓦里安（Varian）已获得美国食品和药物管理局（FDA）510（k）批准，为其Ethos放射治疗系统提供新功能。

Enhanced algorithms now drive the Ethos Intelligence Optimization Engine (IOE) to further optimize treatment planning and dose delivery. Images acquired on Ethos’ HyperSight imaging option are also now integrated into software to enable direct dose calculation and adapt treatments.

增强的算法现在推动Ethos智能优化引擎（IOE）进一步优化治疗计划和剂量输送。在Ethos的HyperSight成像选项上采集的图像现在也被集成到软件中，以实现直接剂量计算和适应治疗。

Ethos was first launched in 2019. Varian’s data demonstrates that providers treating with Ethos selected the adapted treatment plan 88% of time to be more beneficial for patients. Using Ethos, clinicians can select online or offline adaptation—or conventional image-guided radiotherapy.

Ethos于2019年首次推出。瓦里安的数据表明，使用Ethos治疗的提供者在88%的时间内选择了适应的治疗计划，以对患者更有益。使用Ethos，临床医生可以选择在线或离线适应或常规图像引导放疗。

The latest version expanded to in 70+ AI-segmented anatomical structures in the head & neck, thorax, abdomen, pelvis, and bowel regions when using HyperSight images. Ethos also now has seamless data sharing and exchange with the ARIA CORE oncology management solution.

当使用HyperSight图像时，最新版本扩展到头颈部，胸部，腹部，骨盆和肠道区域的70+AI分割解剖结构。Ethos现在还可以与ARIA CORE肿瘤学管理解决方案无缝共享和交换数据。

Varian said that Ethos 2.0 gives clinical teams a versatile, comprehensive solution, as well as optimizes clinical and operational efficiencies.

瓦里安说，Ethos 2.0为临床团队提供了一个多功能、全面的解决方案，并优化了临床和运营效率。

'Our latest Ethos system reflects our ongoing commitment to develop innovative solutions that make real-time, adaptive radiotherapy treatment easier to accomplish in any setting,' said Arthur Kaindl, Head of Varian. 'By reducing workflow complexity, leveraging advanced, AI-powered technology, and enabling greater connectivity to patient data across our ecosystem, we continue to invest in comprehensive tools to help clinicians integrate precision throughout the patient journey.'.

瓦里安公司负责人亚瑟·坎德尔（ArthurKaindl）说：“我们最新的Ethos系统反映了我们不断致力于开发创新解决方案，使实时、适应性放射治疗在任何情况下都更容易完成。”通过降低工作流程的复杂性，利用先进的人工智能技术，并在我们的生态系统中实现与患者数据的更大连接，我们继续投资于综合工具，以帮助临床医生在整个患者旅程中整合精确度。”。
