The Calypso System is intended for use as an adjunct in treatment planning and radiation the our poor ijo align and/or the patient's position relative to the isocenter of a radiation therapy system. The Calypso System provides accurate, precise and continuous localization of a treatment isocenter by using two or more Beacon transponders. The optional Dynamic Edge™ Gating component may signal a radiation therapy system to impose a beam-hold when the treatment target position has moved outside the defined tracking limits and to signal the radiation therapy system to remove the beam-hold upon the target's return to a position inside the defined tracking limits. The Dynamic Edge Gating feature has been shown to be compatible with Varian and Siemens radiation therapy treatment systems with external gating interfaces. Implanted Beacon® transponders are indicated for use to radiographically and electromagnetically mark soft tissue for future therapeutic procedures. Permanent Beacon transponders are indicated for implantation in the prostate and the peri-prostatic tissue (i.e., prostatic bed) to align and monitor the treatment isocenter in real time during radiation therapy. Surface Beacon® transponders are indicated for temporary external placement on the skin, to monitor respiratory motion and other patient motion in real time during radiation therapy.

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 non-ionizing electromagnetic signals from passive markers, called Beacon® transponders which are implanted in or near the treatment target or placed externally on the surface of a patient. Implanted Beacon transponders when used with the Calypso System enable objective measurement of the location of the target in 3 dimensions. The system operator uses this information to align the patient's treatment target to the isocenter of the therapy system prior to treatment. This information can also be used to monitor (track) the position of the treatment target during radiation therapy treatment. When using Surface Beacon transponders this information can be used to monitor respiratory motion and other patient motion in real time during radiotherapy. When correlated to the patient's treatment target motion the system provides objective measurement of the location of the target in 3 dimensions. The Dynamic Edge™ Gating feature enables the Calypso System to interface with radiation therapy systems configured with gating capabilities via an interface to external systems. With this optional feature added to the Calypso System, a beam hold is signaled to the radiation therapy system when the treatment target position has moved outside the defined tracking limits. The radiation therapy system is signaled to remove the beam-hold upon the target's return to a position inside the defined tracking limits.

The Calypso® System is intended for use as an adjunct in treatment planning and radiation therapy, to align and monitor the patient's position relative to the isocenter of a radiation therapy system.

Use of the Calypso System for target localization is based on the system's detection of non-ionizing electromagnetic signals from passive markers, called Beacon® transponders. The Beacon Transponders are implanted in either the prostatic tissue (i.e., prostatic bed). When used with the Calypso System, the Beacon transponder signals enable objective measurement of the location of the treatment target in 3 dimensions.

The Calypso 4D Localization System is intended for use as an adjunct in treatment planning and radiation therapy, to align and monitor the patient's position relative to the isocenter of a linear accelerator. The Calypso System provides accurate, precise and continuous localization of a treatment isocenter by using two or more Beacon transponders. Beacon transponders are indicated for use to radiographically and electromagnetically mark soft tissue for future therapeutic procedures. Permanent Beacon transponders are indicated for permanent implantation in the prostate and the peri-prostatic tissue (i.e., prostatic bed).

The Calypso System with the Dynamic Edge™ Gating modification enables the Calypso System to interface with radiation therapy systems configured with gating capabilities via an interface to external systems. This modification includes updated computer software and hardware. All other features of the Calypso System remain as cleared by K060906 and K080726.
