초록
Since MLC used in VMAT is a stepped shield, leakage dose may occur between theleaves. In this study, we compared the skin doses of VMAT treatment plan with Jaw Trackingapplied to CT image obtained using phantom and VMAT treatment technology plan withoutJaw Tracking, and confirmed the usefulness of Jaw Tracking method. We intend to present adirection that can reduce patient exposure due to leakage dose of MLC. As a result, when the JawTracking method was used, the skin dose was reduced by 2.00 cGy on average, and the skin dosewas reduced by 3% compared to the Fixed Jaw method. As a result, when using the Jaw Trackingmethod with VMAT, the leakage and transmission radiation generated between the MLCleaves are reduced, and radiation treatment with a protective effect on the skin is possible whencompared with the case using Fixed Jaw.
