Hayward, Calif.-based Reflexion Medical Inc. has received the green light from the U.S. FDA to market its Reflexion X1 system for standard radiation therapy treatments. The company, which also is breaking new ground with the development of biology-guided radiotherapy (BgRT), aims to eventually bring multi-tumor precision radiotherapy to all stages of cancer treatment. The FDA cleared the Reflexion X1 for stereotactic body radiotherapy, stereotactic radiosurgery and intensity modulated radiotherapy. The clearance allows physicians to treat a single tumor with precise beam shaping and radiation dose delivery.
