    SYNCHRONY RESPIRATORY TRACKING SYSTEM

    Intended Use

    The Synchrony Respiratory Tracking System provides an option to the CyberKnife Robotic Radiosurgery System and CyberKnife VSI Robotic Radiosurgery System that enables dynamic image-guided stereotactic radiosurgery and precision radiotherapy of lesions, tumors and conditions that move under the influence of respiration.

    Device Description

    Irradiation of lesions that move during breathing, such as those located in the lung or near the diaphragm, are typically performed during patient breath-holds. The Synchrony Tracking System option to the CyberKnife System is designed to treat lesions while they are moving during the respiratory cycle. This offers the ability to reduce normal tissue exposure by using smaller irradiation margins, shorten treatment times, increase accuracy and provide more comfort for the patient.

    During respiratory tracking, a correspondence between surface (e.g., thorax/abdomen) movement and movement of the target lesion is developed prior to the start of treatment and is regularly updated during treatment each time the CyberKnife System acquires a new pair of x-ray images. This correspondence is then used to estimate lesion position in real time by monitoring surface movement during treatment.

    The Synchrony Tracking System provides the CyberKnife System with the capability to monitor the patient's respiration and command the robot manipulator to compensate for the treatment target motion within the body, in real-time, while the radiation is being delivered.

    The Synchrony Respiratory Tracking System includes a sensor assembly, tracking targets, electronics to translate signals, and a controller.
