What is GPS for the Body Technology?

The implanted Beacon® electromagnetic transponders work with the Calypso® 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 technology. 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-millimeter* electromagnetic localization accuracy and additional non-ionizing radiation doses are not needed.

The Calypso System facilitates accurate target localization for maximum clinical confidence.

Actual prostate motion demonstrating drifting of the prostate during treatment up to 1cm for more than 2 minutes.

Prostate motion documented in the daily report demonstrates motion of the prostate of greater than 1cm over 6 minutes.

The 4D Electromagnetic Array contains an energy source that excites the Beacon transponders and receivers that detect each transponder's frequency to determine its location coordinates.

At the heart of Calypso's technology are three implantable Beacon transponders - each transmits a unique non-ionizing radiofrequency signal to the array, generating position and motion information about the target.
