We have considered whether it is possible to determine the prescribed MU and the thickness of the compensators at SAD 350 cm, 400 cm, using data calculated at SAD 300 cm which is the limit of RTPS of our own facility. The dose characteristics at long SAD were acquired and corrections were made so that the calculation result of RTPS at SAD 300 cm would be the value measured under the condition of long SAD. The maximum difference between the MU of this method and the MU irradiated to the patient was 3.6%. We got a good result of thickness of the compensators calculated for the femur and lower leg showed, however the differences were greater in other parts. Although some improvement is necessary, it was suggested that the prescribed MU and the thickness of the compensators presumed using RTPS can be used for TBI setup\n","subitem_description_type":"Abstract"}]},"item_3_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"13694","nameIdentifierScheme":"WEKO"}],"names":[{"name":"テラシマ,
