| Objective The quality assurance(QA) program was designed for gamma knife stereotactic radiosurgery to check and maintain the hospital to comply with current regulations and ensure the high precision and safety of the treatment.Methods A comprehensive quality assurance program separated into two aspects: equipment related QA and treatment procedure related QA. The items are checked on a daily, weekly, monthly or annual basis. A complete list of items with their respective timetables and tolerances was provided. ResultsThe range of deviation of the dose rate output was 0-0.3%(<3%). The mechanical isocenter accuracy was found to be 0.26-0.31 mm (<0.5 mm). It is acceptable that the experience showed very small margins of error. Conclusions Items included in this routine quality assurance program could ensure the accuracy and safety of gamma knife treatment. |
