C‑RAD Overview

C‑RAD is a global medical device company with headquarter in central Uppsala, Sweden. We develop, produce, and sell innovative solutions to healthcare customers. The focus is on patient positioning and monitoring within radiation therapy. We are a market leader in the field of optical patient positioning.

Groundbreaking technology for better cancer care

C‑RAD develops surface‑guided solutions for radiation therapy to allow highly accurate dose delivery to the tumor, and at the same time, to protect healthy tissue from unwanted exposure. Using high‑speed 3D cameras, C‑RAD supports the initial patient setup process and monitors the patient’s motion during treatment to ensure correct positioning and efficient workflow. The mission with the C‑RAD products is to help cure more cancer patients and improve their quality of life.

C‑RAD was founded in 2004 by researchers from Karolinska Institute and Karolinska Hospital in Solna, researchers from the Royal Institute of Technology in Stockholm and people with long industrial experience of radiation therapy. The first product was launched in 2006 and was the C‑RAD Sentinel™ system. Since then, the technology has been under constant development. C‑RAD AB is listed on Nasdaq Stockholm Small Cap since 2014.
