Calypso 4D Localization System

In treating prostate cancer with radiation therapy, it is critical that all the necessary radiation gets to the tumor site while avoiding radiation to the bladder and rectum. However, the normal motion of the prostate presents challenges in delivering precise radiation therapy to such a small target.

A new technology, the Calypso® 4D Localization System™ now allows our radiation oncology experts to precisely set up prostate radiation therapy and then monitor the prostate’s position in real time during treatment in a way never before possible.

The Calypso System works like GPS for the body:

• Tiny electromagnetic transponders are implanted into the prostate in an outpatient procedure prior to treatment.
• These beacon transponders emit radiofrequency waves which allow very accurate alignment of the prostate before each treatment session.
• Doctors are able to monitor the position of the prostate in real time during treatment delivery.
