We will report its structure and electrical characteristics.\nPAAC is configured by several Patch Antennasof it plate like radiation device and ground board (a screen), and radiation device is covered by ground board. Each antenna was put pm the parallel to the axis of the circular cylinder.\nThis coil was designed to an antenna either for transmission and reception, experimentally. In transmission mode, the coil elements circularly polarized.\nWe assumed the coil inside diameter 150mm, it hold enough space to monkey's head.\nAs for Q, a very high value was obtained more than 450 at no loading at 300.3MHz. Loaded by salt water, the Q value was 270.\nAbout 4 times signal-to-noise ratio signal was obtained with olive oil phantom in this 7Tesla system, compared to the 1.5Tesla MR system.\nThere are folling characteristics to this coil.\n(1)Because the outside of ground board does not havemost electricfield, it is easy to post a circuit attached to things such as an adjustment circuit and a blocking circuit in the inside of a coil.\n(2)We can choose feeding point at any place other than an element end and can coordinate feeding point impedance hereby. We make use of such a good point and want to review more characteristic improvement.","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":"The 6th Japan-France Workshop on Radiobiology and Isotopic imaging","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":"Nakajima, Manabu"}],"nameIdentifiers":[{"nameIdentifier":"611053","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakajima, Iwao"}],"nameIdentifiers":[{"nameIdentifier":"611054","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshitome, Eiji"}],"nameIdentifiers":[{"nameIdentifier":"611055","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ikehira, Hiroo"}],"nameIdentifiers":[{"nameIdentifier":"611056","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中島 学","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"611057","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中島 巌","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"611058","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉留 英二","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"611059","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"池平 博夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"611060","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":"Development of a volume coil (PAAC) for 7T/400mm/SS System(NIRS/KOBELCO/Bruker)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Development of a volume coil (PAAC) for 7T/400mm/SS System(NIRS/KOBELCO/Bruker)"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2006-08-23"},"publish_date":"2006-08-23","publish_status":"0","recid":"61726","relation_version_is_last":true,"title":["Development of a volume coil (PAAC) for 7T/400mm/SS System(NIRS/KOBELCO/Bruker)"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:39:01.851612+00:00"}
