| Abstract: | CT simulator can provide patients' anatomical information for the design of radiotherapy plan. It is the basis for 3D plan design, dose calculation and plan evaluation of radiation therapy. The purpose of the quality control of CT simulator is to ensure the safety of CT simulated positioning process and accurate delineation of the radiotherapy target area and its surrounding vital organs, as well as to provide accurate data required for the dose calculation of radiotherapy plan. This guideline mainly covers four aspects of quality control: mechanical properties, image quality, positioning process and radiation protection. |
