| Abstract: | Objective To emphasize the special requirement and measure of quality control in the static physical compensator intensity-modulated radiotherapy by verifying the dose error.Methods The absolute dose between static physical compensator IMRT plan and polymethyl phantoms was compared in 17 cases.Results The absolute dose error is controlled within 5%,and the mean error is 3.8%.Conclusion The strict and detailed measure of quality control and quality assurance may be the foundation that IMRT could satisfy the clinical requirements. |
