However, it remains unclear whether the method can be used for imaging with the clinical dose levels of carbon-ion and whether the bremsstrahlung X-ray can be detected from the deeper part of the body. To clarify these points, we developed a new high resolution low-energy X-ray camera and conducted imaging of the secondary electron bremsstrahlung X-ray during the irradiation of carbon-ions of different energies and intensities. Imaging was also tried with an X-ray camera using a human-head-sized, 17-cm diameter cylindrical phantom. To develop a high resolution imaging detector for a low-energy X-ray, we used a 20 × 20 × 0.5 mm thick cerium-doped yttrium aluminum perovskite, YA1O3 (YAP(Ce)) scintillator plate, which was optically coupled to a 25mm square high quantum efficiency (HQE) type position sensitive photomultiplier tube (PSPMT). The imaging detector was encased in a 2 cm thick tungsten container and a pinhole collimator was attached to its camera head. After evaluating the camera’s performance, secondary electron bremsstrahlung X-ray imaging was tried during irradiation of the carbon-ion and compared the results with a Monte Carlo simulation. We imaged the beam tracks by the secondary electron bremsstrahlung X-ray in real-time during irradiation of the carbon-ion and imaging and range estimation were possible even with near clinical dose level of 7.5 × 108 particles of carbon-ion. Clear images of a secondary electron bremsstrahlung X-ray were also obtained for a 17-cm diameter cylindrical phantom. The measured images were good agreement with the Monte Carlo simulation. We confirmed that our developed YAP(Ce) camera is promising for imaging secondary electron bremsstrahlung X-rays during irradiation of carbon-ions even near clinical conditions.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IOP Publishing"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1088/1361-6560/ab2072","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/10.1088/1361-6560/ab2072","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_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":"Seiichi, Yamamoto (Nagoya Univ.)"}],"nameIdentifiers":[{"nameIdentifier":"791015","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamaguchi, Mitsutaka"}],"nameIdentifiers":[{"nameIdentifier":"791016","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takashi, Akagi (Hyogo Ion Beam Medical Center)"}],"nameIdentifiers":[{"nameIdentifier":"791017","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Makoto, Sasano (Mitsubishi Electric Corp.)"}],"nameIdentifiers":[{"nameIdentifier":"791018","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kawachi, Naoki"}],"nameIdentifiers":[{"nameIdentifier":"791019","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamaguchi, Mitsutaka","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"791020","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kawachi, Naoki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"791021","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":"Development of a YAP(Ce) camera for the imaging of secondary electron bremsstrahlung X-ray emitted during carbon-ion irradiation toward the use of clinical conditions","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Development of a YAP(Ce) camera for the imaging of secondary electron bremsstrahlung X-ray emitted during carbon-ion irradiation toward the use of clinical conditions"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-05-08"},"publish_date":"2019-05-08","publish_status":"0","recid":"76220","relation_version_is_last":true,"title":["Development of a YAP(Ce) camera for the imaging of secondary electron bremsstrahlung X-ray emitted during carbon-ion irradiation toward the use of clinical conditions"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:02:12.268855+00:00"}
