Calypso Podcast

During radiation treatment of prostate cancer, Emory is improving patient outcomes through use of the Calypso GPS system. The Calypso GPS system provides precise, real-time tracking of the prostate during radiation treatment. The prostate can move or shift slightly at any time, even during radiation treatment, which means that a tumor might not receive the correct dose of radiation. Moreover, some radiation might hit healthy organs, causing unwanted side effects. With the Calypso GPS system, radiation can be continuously targeted at the prostate.

The system relies on 3 rice-sized beacons that are implanted in the prostate in a non-invasive, outpatient procedure. Through harmless electromagnetic waves, much like a radar signal, the Calypso GPS system communicates with these beacons to precisely calculate the position of the prostate with sub-millimeter accuracy. Now, Emory doctors can monitor the movement of the prostate during treatment and keep the radiation focused on the tumor.

The Emory Department of Radiation Oncology, part of Emory’s Winship Cancer Institute, is the only center in the state of Georgia that offers patients with prostate cancer the new Calypso GPS Medical System treatment option.

Patient Advantages:

  • It allows for more accurate prostate tumor radiation delivery; the sub-millimeter GPS allows precise delivery of radiation.
  • The system tracks the prostate in real-time during treatment. If the prostate moves, the radiation beam can be adjusted or stopped.
  • There are fewer side effects. Less radiation exposure to healthy tissue means patients experience fewer and less severe side effects from treatment.
