Calypso® 4D Localization System™ for prostate cancer

What is the Calypso® 4D Localization System™?

The Calypso® 4D Localization System™ helps our doctors deliver focused doses of radiation with greater precision to prostate cancer patients receiving external beam radiation therapy (EBRT).

Also known as GPS for the Body®, this technology allows our prostate cancer radiation therapy team to continuously track movement of the prostate in real time and concentrate radiation to the tumor.

The Calypso system features a 4D Console™ that allows our radiation oncologists to see exactly where the tumor is during radiation treatment. Before treatment, patients undergo a simple outpatient procedure, where Beacon® transponders are implanted into the skin using ultrasound guidance. Each transponder is as small as a grain of rice. The Beacon transponders then communicate with Calypso during radiation treatment using safe, radiofrequency waves.

Calypso is currently FDA approved for use in the treatment of prostate cancer, as well as all soft-tissue tumors, except those in the lung.

Calypso® 4D Localization System™ for prostate cancer

The prostate can move during radiation treatment as a result of breathing and normal movement in the intestines. Typically, radiation oncologists expand the treatment area to ensure the moving target is irradiated. In the process, healthy tissue near the prostate may also be affected, leading to a high rate of urinary, bowel and sexual side effects.

In this recent generation of the Calypso system, the Beacons are able to show the position of the patient’s tumor 25 times a second, and automatically shut the beam off in the event of a cough, sneeze, stomach bubble or other internal change of position that moves the tumor out of the X-ray beam. By targeting cancer cells and avoiding nearby healthy tissues, Calypso spares the bladder, colon and other critical structures. Common side effects of prostate cancer radiation therapy, such as urinary and bowel frequency and erectile dysfunction, may be greatly minimized through the use of Calypso technology.
