A high-dose concentration of proton beam\nreduces damage to normal tissues. However, it also requires a high accuracy of irradiation. PET is generally\nused to verify the proton range after irradiation, but, the distributions of positrons and the energy deposited by\nprotons are not similar to each other. Recently, prompt gamma-ray imaging has attracted attention as a new,\nonline imaging technique. In particular, 4.4 MeV gamma rays emitted from 12C* is one of the best probes to\nmonitor the proton dose, however imaging techniques are far from established. We have developed a novel,\n3-D position sensitive Compton camera based on Ce:GAGG scintillators coupled with multi-pixel photon counter\n(MPPC) arrays, thus making it optimized for imaging in the 1–10 MeV range. The angular resolution is 5 degrees\n(FWHM) at 4.4 MeV. We have established various methods to discriminate multiple-Compton and escape events,\nboth of which can be critical backgrounds for precise imaging of prompt gamma rays. By irradiating a 70 MeV\nproton beam on the PMMA phantom, we demonstrated that 4.4 MeV gamma ray image is sharply concentrated\non the Bragg peak, as was expected from the PHITS simulation.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.nima.2018.11.032","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://doi.org/10.1016/j.nima.2018.11.032","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0168-9002","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":"Mochizuki, S."}],"nameIdentifiers":[{"nameIdentifier":"782083","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kataoka, J."}],"nameIdentifiers":[{"nameIdentifier":"782084","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koide, A."}],"nameIdentifiers":[{"nameIdentifier":"782085","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fujieda, K."}],"nameIdentifiers":[{"nameIdentifier":"782086","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Maruhashi, T."}],"nameIdentifiers":[{"nameIdentifier":"782087","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kurihara, T."}],"nameIdentifiers":[{"nameIdentifier":"782088","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sueoka, K."}],"nameIdentifiers":[{"nameIdentifier":"782089","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tagawa, L."}],"nameIdentifiers":[{"nameIdentifier":"782090","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoneyama, M."}],"nameIdentifiers":[{"nameIdentifier":"782091","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Inaniwa, Taku"}],"nameIdentifiers":[{"nameIdentifier":"782092","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Inaniwa, Taku","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"782093","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":"High-precision Compton imaging of 4.4 MeV prompt gamma-ray toward an on-line monitor for proton therapy","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"High-precision Compton imaging of 4.4 MeV prompt gamma-ray toward an on-line monitor for proton therapy"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-09-05"},"publish_date":"2019-09-05","publish_status":"0","recid":"76671","relation_version_is_last":true,"title":["High-precision Compton imaging of 4.4 MeV prompt gamma-ray toward an on-line monitor for proton therapy"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:14:42.979690+00:00"}
