Calypso System Overview

The Calypso® System delivers precision and accuracy—continuously and in real time—enabling radiation oncology clinicians to keep the target in the path of the radiation beam at all times. By detecting the slightest tumor movement—and enabling the patient to be repositioned if necessary—the Calypso System helps clinicians deliver maximum radiation directly to the tumor while avoiding healthy surrounding tissues and organs.
