Overview
Robotic couches and patient positioning systems improve accuracy for stereotactic radiosurgery and stereotactic body radiotherapy by enabling submillimeter adjustments. Robotic arms integrated with imaging guidance support noncoplanar beam delivery and adaptive workflows. These systems enhance targeting while minimizing dose to adjacent normal tissues.
Adaptive Radiotherapy
Robotic positioning combined with onboard imaging enables adaptive radiotherapy where daily anatomy changes are accounted for in treatment delivery. Automated couch shifts and robotic alignment reduce setup variability and support hypofractionated regimens. Integration with treatment planning systems streamlines adaptive decision making.
Safety and Verification
Image guided verification and collision avoidance systems are critical when using robotic delivery and positioning to prevent unintended motion. End to end QA including phantom based tests validates geometric accuracy and dosimetric fidelity. Multidisciplinary protocols ensure safe implementation and monitoring.
Clinical Impact
Robotic enhancements support more precise dose delivery which can improve local control and reduce toxicity for selected tumors. Workflow efficiency gains may increase throughput for high complexity treatments. Evidence from clinical studies guides selection of patients who benefit most from robotic assisted stereotactic approaches.
