The gradiometer, which is based on a low-Tc superconducting quantum interference device, detects the gradient of a magnetic field in two orthogonal directions. Gradiometer position is easy to adjust by operating the gantry to drive the cryostat in both the swinging and axial directions. As a result, a fMCG waveform for 25  weeks\u0027 gestation was measured under an unshielded environment in real time. Moreover, the P and T waves for 25 and 34  weeks\u0027 gestation, respectively, were obtained by averaging. These results indicate that this two-dimensional gradiometer is one of the most promising techniques for measuring fetal heart rate and diagnosing fetal arrhythmia.", "subitem_description_type": "Abstract"}]}, "item_5_identifier_34": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2241/98664"}]}, "item_5_publisher_27": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "American Institute of Physics"}]}, "item_5_relation_10": {"attribute_name": "PubMed\u756a\u53f7", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "18377051", "subitem_relation_type_select": "PMID"}}]}, "item_5_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1063/1.2897588", "subitem_relation_type_select": "DOI"}}]}, "item_5_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u00a9 2008 American Institute of Physics"}]}, "item_5_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0034-6748", "subitem_source_identifier_type": "ISSN"}]}, "item_5_source_id_9": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "attribute_value_mlt": [{"subitem_source_identifier": "AA00817730", "subitem_source_identifier_type": "NCID"}]}, "item_5_subject_20": {"attribute_name": "NII\u30b5\u30d6\u30b8\u30a7\u30af\u30c8", "attribute_value_mlt": [{"subitem_subject": "\u533b\u5b66", "subitem_subject_scheme": "Other"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Seki, Yusuke"}], "nameIdentifiers": [{"nameIdentifier": "56016", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kandori, Akihiko"}], "nameIdentifiers": [{"nameIdentifier": "56017", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kumagai, Yukio"}], "nameIdentifiers": [{"nameIdentifier": "56018", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ohnuma, Mitsuru"}], "nameIdentifiers": [{"nameIdentifier": "56019", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ishiyama, Akihiko"}], "nameIdentifiers": [{"nameIdentifier": "56020", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ishii, Tetsuko"}], "nameIdentifiers": [{"nameIdentifier": "56021", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nakamura, Yoshiyuki"}], "nameIdentifiers": [{"nameIdentifier": "56022", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Horigome, Hitoshi"}], "nameIdentifiers": [{"nameIdentifier": "56023", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Chiba, Toshio"}], "nameIdentifiers": [{"nameIdentifier": "56024", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2013-12-19"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "RSI_79-3.pdf", "filesize": [{"value": "267.9 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 267900.0, "url": {"label": "RSI_79-3.pdf", "url": "https://tsukuba.repo.nii.ac.jp/record/15623/files/RSI_79-3.pdf"}, "version_id": "b9aa4c85-5993-499e-b21a-7fd52a81fe1f"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Unshielded fetal magnetocardiography system using two-dimensional gradiometers", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Unshielded fetal magnetocardiography system using two-dimensional gradiometers"}]}, "item_type_id": "5", "owner": "1", "path": ["2780/556", "3/62/5600/89"], "permalink_uri": "http://hdl.handle.net/2241/98664", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2008-04-25"}, "publish_date": "2008-04-25", "publish_status": "0", "recid": "15623", "relation": {}, "relation_version_is_last": true, "title": ["Unshielded fetal magnetocardiography system using two-dimensional gradiometers"], "weko_shared_id": 5}
