GPS for the Body® Tracks Cancer in Patients During Treatment

What is GPS for the Body®?

The implanted Beacon® electromagnetic transponders work with the Calypso® 4D Localization System™ to provide guidance to the clinician on the position and movement of the prostate during radiation therapy. Clinicians use the motion data provided by the Calypso System to guide radiation therapy setup and monitor the prostate position during treatment delivery.

The implanted Beacon® transponders and the Calypso System provide the clinician continuous, real-time monitoring of the prostate and alerts the clinician when the target is outside of acceptable boundaries due to organ motion, thereby enabling corrections during treatment delivery — GPS for the Body®. The implanted Beacon® transponders and the Calypso System provide objective guidance that enables the clinician to manage organ motion and expanded treatment delivery opportunities. In addition, clinician confidence is enhanced through accurate sub-millimeter1 electromagnetic localization accuracy and additional non-ionizing radiation doses are not needed.



The Beacon® electromagnetic transponders and the Calypso® 4D Localization System™, referred to as GPS for the Body®, is a system that provides an innovative solution for target localization and monitoring during radiation therapy delivery.

The Calypso® 4D Localization System™ displays and records prostate motion—continuously in real-time—through an intuitive graphical user interface. Clinicians use the visual and audio cues to manage prostate motion when the organ moves outside of the thresholds set by the radiation department.
