Prostate Localization

Prostate Localization

Calypso is a prostate localization system often referred to as GPS for the body. It uses three small beacons inserted into the prostate or prostate bed by a urologist. This is done in the physician’s office, similar to the way the initial prostate biopsy was done. Insertion is a one-time procedure. The beacons are never removed from the prostate. These are inserted at least a week prior to the simulation CT. These beacons emit a radio frequency that is recognized by a localization plate that hovers over the patient during radiation treatments. The three beacons allow triangulation of the prostate and allow the radiation therapists to position the prostate directly in the radiation field. In addition to initial positioning of the prostate or prostate bed, Calypso continuously tracks motion during the treatment. This is the only system available that allows the radiation therapists to monitor movement during the treatment and adjust accordingly. The majority of patients are eligible for the Calypso system; however, the criteria to be a candidate will be determined during a consultation with a radiation oncologist.
