If you have prostate cancer and your doctor has prescribed radiation therapy, there are some important things you should know. Your organs naturally move during radiation treatment and your doctor cannot predict which way or how much your organs will move. When your organs move during radiation therapy delivery the tumor may not get the right amount of radiation. Other nearby organs may receive radiation that is not meant for them during the radiation treatment.

Fortunately, the Calypso® System and implanted Beacon® electromagnetic transponders can help your doctor know when the prostate is not aligned with the radiation beam during your treatment.

The Calypso System is different from other methods to prepare you for radiation treatment. The Calypso System uses radiofrequency waves which allow very accurate alignment of your prostate before each treatment session. It can also be used to monitor the position of the prostate at all times during your radiation treatment delivery.
