Quality Control Test of Transcranial MRI-guided Focused Ultrasound Treatment System before Surgery

Objective To investigate the pre-treatment preventive maintenance and quality control procedure of MRI system and transcranial MRI-guided focused ultrasound (TcMRgFUS) treatment system by monitoring quality control of these two systems. Methods The general performance index and image quality control index of MRI system, as well as the quality assurance program of TcMRgFUS EXABLATE 4000 system were tested and recorded. Results The general performance index and image quality control index of MRI system met requirements. Conclusion Through system detection, the system performance could be monitored, ensuring the accuracy and safety of surgery.
