Therefore, research on next generation PET technologies remains a hot topic worldwide. The Biophysics Program [1] in National Institute of Radiological Sciences (NIRS) [2] carries out basic studies on instrumentation, image reconstruction and data corrections to improve image quality and quantity in nuclear medicine. A depth-of-interaction (DOI) detector will be a key device to get any significant improvement in sensitivity while maintaining high spatial resolution [3-5]. DOI measurement also has a potential to expand PET application fields because it allows for more flexible detector arrangement. As an example, we are developing the world's first, open-type PET geometry \"OpenPET\", which is expected to lead to PET imaging during treatment [6]. We have developed a small prototype to show a proof-of-concept of OpenPET imaging [7]. The DOI detector itself continues to evolve with the help of recently developed semiconductor photodetectors, often referred to as silicon photomultipliers (SiPMs). We are developing a SiPM-based DOI detector \"X'tal cube\" to achieve sub-mm spatial resolution, which is reaching the theoretical limitation of PET imaging. We have developed a prototype of 1mm isotropic detector resolution, which equals the world record [8].\n\\n2.Research topics\n Open-type PET \"OpenPET\" and its applications\n Next generation DOI detector \"X'tal cube\"\n Integrated PET/MRI system\n Feasibility study of an extendable, entire body PET\n Real-time tumor tracking by the OpenPET\n Real-time dose distribution monitoring system in interventional radiology\n PET attenuation correction methods based on MR images\n Quantification methods for PET data","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"2nd SNU-NIRS Workshop on Nuclear Medicine Imaging Science and Technology","subitem_description_type":"Other"}]},"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":"Yamaya, Taiga"}],"nameIdentifiers":[{"nameIdentifier":"640371","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ito, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"640372","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山谷 泰賀","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"640373","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"伊藤 浩","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"640374","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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Introduction of PET Physics Research in NIRS","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Introduction of PET Physics Research in NIRS"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-05-07"},"publish_date":"2013-05-07","publish_status":"0","recid":"64988","relation_version_is_last":true,"title":["Introduction of PET Physics Research in NIRS"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:05:19.416549+00:00"}
