VARIAN MEDICAL SYSTEMS, INC. ASM0341 Calypso Beacon Care Package-Lung

The Beacon transponder is a wireless device composed of an internal circuit and encapsulation materials. The internal circuit resonates in response to an external AC magnetic field. The resonance signal is used to measure the location of the transponders by the Calypso System. The Surface Beacon transponder is comprised of two Beacon transponders. The Surface Beacon transponder in its final packaged state is known as the Beacon Care Package - Surface.

The Calypso System utilizes non-ionizing electromagnetic and optical technology to provide accurate, objective, and continuous localization of a treatment target for patient alignment and target position monitoring during radiation therapy. Use of the Calypso System for target localization is based on the system’s detection of electromagnetic signals from passive implanted markers, called Beacon transponders. The Beacon transponders are placed on the patient’s skin surface or implanted in or near the treatment target. When used with the Calypso System, the Beacon transponder signals enable objective, continuous measurement of the localization of the treatment target in 3 dimensions. The system operator uses this information for patient alignment and continuous target positioning (i.e., tracking) during radiation therapy treatment.
