Turning cancer on
itself > Finally

RefleXion’s biology-guided radiotherapy (BgRT) allows us to detect and respond to signals emitted from the cancer itself, and for the first time, use them to guide immediate treatment.

Real-Time Guidance

Cancer is talking.
We’re listening.

When PET radiotracers are introduced into the body, cancer absorbs them and acts as a biological beacon, which our machine can use to track and treat cancer in real time.

Targeting Cancer

Good news for organs. Bad news for tumors.

Our technology aims to deliver high doses of radiation to tumors, even while in motion, for greater impact to the tumor with less dose to the surrounding tissue.

Learn About Targeting

Metastatic Disease

A world where stage is just a number.

Most patients with stage four cancer are not considered candidates for definitive radiotherapy due to the challenge of treating multiple tumors. Our breakthrough technology is challenging that and aims to treat multiple tumors, in parallel, during a single session. 

Discover the Potential

Combination Treatment

Come at cancer from every angle.

Treatment isn’t a one-size-fits-all situation. For many patients, the best treatment plan is a combination of multiple therapies. RefleXion will work together with chemotherapy, immunotherapy and targeted drugs for potentially better outcomes.

Stanford Treats First Patient on RefleXion X1

Physicians at Stanford Radiation Oncology have treated the first patient using the RefleXion X1 system. The RefleXion X1 combines high quality computed tomography (CT) imaging, known as fan-beam CT, with a linear accelerator to reduce motion artifacts that can inhibit accurate targeting of the radiation dose to a patient's tumor. According to the company, its design rotates up to 60 times faster than other linear accelerators and modulates dose delivery from 100 points per beam station.
