China's State Food and Drug Administration (SFDA) has granted clearance for Varian Medical Systems' Unique medical linear accelerator, a single-energy machine for treating cancer with advanced forms of image-guided radiotherapy. The system can be used to deliver the company's intensity-modulated radiotherapy (IMRT) and RapidArc treatments, which precisely target tumours while minimising exposure of surrounding healthy tissues.
The Unique radiotherapy system is described as the first low-energy (6MV) radiotherapy system that can be outfitted with high-tech image-guidance, beam shaping and RapidArc technology for rapid treatment delivery. It also includes the latest release of Varian's Eclipse treatment planning software, offering clinicians seamless workflow for planning and delivering advanced radiotherapy treatments.
Additionally, Unique can be used to deliver RapidArc radiotherapy, an arc-based approach that makes it possible to complete an image-guided IMRT treatment in a matter of minutes. Varian says the process is up to four times faster than is possible with conventional IMRT. The Unique system is equipped for treating cancer of the head and neck, breast, cervix, lung, prostate, and other tumours, and are available in two configurations: Unique Performance Edition, which incorporates the tools needed for image-guided RapidArc radiotherapy, and Unique Power Edition, a more basic platform that can be upgraded at a later time. Either package is ideal for treatment centres aiming to switch from older cobalt units to modern radiotherapy technology.
