(Fierce Medical Devices) – Reflexion Medical has raised $46 million to develop the first biology-guided radiotherapy system that offers targeted cancer treatment. Last fall, the Hayward, CA-based startup said it had created a prototype device that was ready to go into the clinic. This Series B infusion is earmarked for expanding the company’s engineering, regulatory and commercial groups.

Reflexion’s biology-guided radiotherapy (BgRT) system uses both anatomic (computed tomography) and functional (positron emission tomography) imaging data to create personalized radiotherapy. Targeted cancer treatment can be delivered based on the patient’s particular biology; that could enable delivery of a higher dose of radiation to cancerous lesions as well as more effectively spare the healthy tissue surrounding it.
