Calypso GPS for the Body®

• The Calypso System accurately and precisely tracks the position of targeted tissue in real-time by using radiofrequency waves.
  
  
• Calypso is the only real-time technology for prostate radiation therapy that safeguards you against additional, unnecessary radiation.
  
  
• Because normal bodily functions such as digestion and coughing cause organs to move, during radiation therapy, a prostate tumor can move in and out of the path of the radiation beam. With other treatments, when the tumor moves out of the path, healthy tissue receives the radiation, which may lead to the development of uncomfortable side effects such as bowel or rectal problems, urinary incontinence or irritation, and sexual dysfunction. At the same time, the tumor receives less radiation which may alter the effectiveness of therapy.

How Does Calypso Work?

• Three tiny Beacon® transponders – each the size of a grain of rice – are implanted in your prostate during a quick outpatient procedure.
  
  
• The Calypso System and the implanted Beacon transponders work together during each radiation session to communicate the exact location of your prostate tumor. If the tumor moves outside of the radiation beam, the therapist is immediately alerted and can stop the beam to adjust your position.

Reduced Side Effects Proven with Calypso

• In a recent clinical study, “Assessing the Impact of Margin Reduction” (AIM), researchers compared the results from Calypso patients to a set of patients in a study previously published in the New England Journal of Medicine.
  
  
• In both groups, patients rated their quality of life before and after the completion of their prostate radiation therapy.
  
  
• The comparison demonstrated that the use of Calypso real-time tracking during high-dose external beam radiation therapy resulted in a significant reduction in serious treatment-related side effects.
