CNERGY Check includes the independent Couch Setup Assistant (TCSA), which has been a common feature in many radiotherapy centers. In combination with the workflow manager, the couch is swiftly and smoothly adjusted for pre-treatment and remote online patient setup corrections. The high level of accuracy in patient setup increases treatment safety and patient care. Also, CNERGY Check prevents treatment until the required pre-treatment patient setup corrections have been performed, minimizing the risk of setup errors or misalignments.¹
