It is however difficult for conventional pencil-beam algorithms to deal with fine structures of these devices due to beam-size growth during transport. This study aims to avoid the difficulty with a novel computational model. The pencil beams are initially defined at the range-compensating filter with angular-acceptance correction for upstream collimation followed by stopping and scattering. They are individually transported with possible splitting near the aperture edge of a downstream collimator to form a sharp field edge. The dose distribution for a carbon-ion beam was calculated and compared with existing experimental data. The penumbra sizes of various collimator edges agreed between them to a submillimeter level. This beam-customization model will be used in the greater framework of the pencil-beam-splitting algorithm for accurate and efficient patient dose calculation.","subitem_description_type":"Abstract"}]},"item_8_relation_13":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"21297242","subitem_relation_type_select":"PMID"}}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1088/0031-9155/56/5/009","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0031-9155","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kanematsu, Nobuyuki"}],"nameIdentifiers":[{"nameIdentifier":"476911","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"兼松 伸幸","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"476912","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-02-14"}],"displaytype":"detail","filename":"6c7e3118090aee5c9830c5f7bf978176.pdf","filesize":[{"value":"246.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"text.pdf","url":"https://repo.qst.go.jp/record/47580/files/6c7e3118090aee5c9830c5f7bf978176.pdf"},"version_id":"250cfe0f-97bf-4c68-842b-ee767eac9349"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Modeling of beam customization devices in the pencil-beam splitting algorithm for heavy charged particle radiotherapy","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Modeling of beam customization devices in the pencil-beam splitting algorithm for heavy charged particle radiotherapy"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-10-18"},"publish_date":"2016-10-18","publish_status":"0","recid":"47580","relation_version_is_last":true,"title":["Modeling of beam customization devices in the pencil-beam splitting algorithm for heavy charged particle radiotherapy"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:38:04.200626+00:00"}
