What is GPS for the Body®?
The implanted Beacon® electromagnetic transponders work with the Calypso®
4D Localization System™ to provide guidance to the clinician on the position
and movement of the prostate during radiation therapy. Clinicians use the motion
data provided by the Calypso System to guide radiation therapy setup and monitor
the prostate position during treatment delivery.
The implanted Beacon® transponders and the Calypso System provide the clinician
continuous, real-time monitoring of the prostate and alerts the clinician when the
target is outside of acceptable boundaries due to organ motion, thereby enabling
corrections during treatment delivery — GPS for the Body®. The implanted Beacon®
transponders and the Calypso System provide objective guidance that enables the
clinician to manage organ motion and expanded treatment delivery opportunities.
In addition, clinician confidence is enhanced through accurate sub-millimeter1
electromagnetic localization accuracy and additional non-ionizing radiation doses
are not needed.
The Calypso® 4D Localization System™ facilitates accurate
target localization for maximum clinical confidence.
The Beacon® electromagnetic transponders and the Calypso® 4D Localization
System™, referred to as GPS for the Body®, is a system that provides an
innovative solution for target localization and monitoring during radiation therapy
delivery.
Actual prostate motion demonstrating drifting of the prostate
during treatment up to 1cm for more than 2 minutes.
Prostate motion documented in the daily report demonstrates
motion of the prostate of greater than 1cm over 6 minutes.
The Calypso® 4D Localization System™ displays and records prostate motion—continuously
in real-time—through an intuitive graphical user interface. Clinicians use the visual
and audio cues to manage prostate motion when the organ moves outside of the thresholds
set by the radiation department.
The 4D Electromagnetic Array™ sends signals to the implanted
Beacon® electromagnetic transponders for activation.
Continuous position and motion information about the prostate
are received by the Calypso® 4D Localization System™ identifying sub-millimeter1
misalignments.
