Thus, range verification techniques, such as online positron-emission-tomography (PET) imaging, hold great potential in clinical practice,\nproviding information on the in vivo beam range and consequent tumor targeting. Furthermore,B+ emitting radioactive ions can be an asset in online PET imaging, depending on their half-life, compared to their stable counterparts. It is expected that using these radioactive ions the signal obtained by a PET apparatus during beam delivery will be greatly increased, and exhibit a better correlation to the Bragg Peak. To this end, FLUKA Monte Carlo particle transport and interaction\ncode was used to evaluate, in terms of annihilation events at rest and dose, the figure of merit in using B+ emitter, radioactive ion beams (RIB+). For this purpose, the simulation results were compared with experimental data obtained with an openPET prototype in various online PET acquisitions at the Heavy Ion Medical Accelerator in Chiba (HIMAC), in collaboration with colleagues from the\nNational Institute of Radiological Sciences’ (NIRS) Imaging Physics Team. The dosimetry performance evaluation with FLUKA benefits from its recent developments in fragmentation production models. The present work estimated that irradiations with RI B+, produced via projectile fragmentation and their signal acquisition with state-of-the-art PET scanner, lead to nearly a factor of two more accurate definition of the signals’ peak position. In addition to its more advantageous distribution shape, it was observed at least an order magnitude higher signal acquired from 11C and 15O irradiations, with respect to their stable counterparts.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IOP Publishing"}]},"item_8_relation_13":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"30252649","subitem_relation_type_select":"PMID"}}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1088/1361-6560/aae431","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://iopscience.iop.org/article/10.1088/1361-6560/aae431","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0031-9155","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Dos Santos Augusto, Ricardo"}],"nameIdentifiers":[{"nameIdentifier":"801947","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Akram, Mohammadi"}],"nameIdentifiers":[{"nameIdentifier":"801948","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田島, 英朗"}],"nameIdentifiers":[{"nameIdentifier":"801949","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉田, 英治"}],"nameIdentifiers":[{"nameIdentifier":"801950","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山谷, 泰賀"}],"nameIdentifiers":[{"nameIdentifier":"801951","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ferrari, Alfredo"}],"nameIdentifiers":[{"nameIdentifier":"801952","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"parodi, Katia"}],"nameIdentifiers":[{"nameIdentifier":"801953","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Dos Santos Augusto, Ricardo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"801954","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mohammadi, Akram","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"801955","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tashima, Hideaki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"801956","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshida, Eiji","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"801957","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamaya, Taiga","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"801958","nameIdentifierScheme":"WEKO"}]}]},"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":"Experimental validation of the FLUKA Monte Carlo code for dose and B+ emitter predictions of radioactive ion beams","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Experimental validation of the FLUKA Monte Carlo code for dose and B+ emitter predictions of radioactive ion beams"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-11-30"},"publish_date":"2018-11-30","publish_status":"0","recid":"49289","relation_version_is_last":true,"title":["Experimental validation of the FLUKA Monte Carlo code for dose and B+ emitter predictions of radioactive ion beams"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:45:38.833360+00:00"}
