Quality Control and Quality Assurance of Body Gamma Knife Treatment

Objective To investigate the quality control and quality assurance in the process of body gamma knife treatment. Methods The vacuum pad was used to fix the patients＂ position, CT scanning was utilized to make sure the position, then the position information was transmitted to treatment planning system through HIS network. The outline of the target was drawn, and the program design and verification were performed before taking body gamma knife treatment. Results The control rate of local tumor was significantly improved and the radiation complications of surrounding normal tissues and organs were reduced. Conclusion By improving quality control and quality assurance standards, the control rate of local tumor is increased and complications of normal tissue are decreased.
