| Research Abstract |
In order to verify the accuracy of quality assurance(QA) for radiation treatment between multi-institutions, beam output and irradiation accuracy were evaluated using radiochromic films, with postal audit to associated hospitals with Osaka University. In case of the results that exceeded the range of tolerance, re-commissioning or re-measurements were proposed in the specific institution. A questionnaire was sent to multi-institutions. The correlation between irradiation methods which consisted of conventional or advanced modalities, and QA equipments was investigated. Based on these results, minimum QA equipment requirements were proposed.
