Near infrared sensitive CCD camera was\nsurrounded by approximately sixty light emitting diodes, which have\nalternating wavelengths of 700 nm and 810 nm. NIR-sensitive camera\ndetected the reflected NIR from superficial subcutaneous tissues.\nBy rotating the camera and LEDs, multiple near infrared projections\nof superficial vascular images were obtained at each wavelength, and\ntomo-synthesis algorithm in accordance with the optical aperture\ntheory was applied to a group of images. The depth discrimination\nwas obtained by the TACT program. Due to the difference and\nsimilarity in the absorption coefficients at 700 nm, 810 nm and\n940 nm wavelength, the venous oxygenation index (VOI) was estimated\nby signal intensities at each wavelength. The VOI was seemed\nto reflect the oxygen saturation level. Results: The superficial vascular\nimaging system using near infrared radiation and tomo-synthesis\nalgorithm created thin tomograms of superficial vascular subcutaneous\ntissues. Changes in VOL after the load test were more\nsignificantly observed on tomograms than on projection images. The\nsuperficial vascular imaging system using near infrared radiation and\ntomo-synthesis algorithm enable to carry out the non-invasive tomograms\nand provide estimates of in oxygen saturation. Also we\nconfirmed that the system is the beneficial tool for finding subcutaneous\nforeign bodies.", "subitem_description_type": "Abstract"}]}, "item_5_description_5": {"attribute_name": "\u5185\u5bb9\u8a18\u8ff0", "attribute_value_mlt": [{"subitem_description": "Proceedings of the 22nd International Congress and Exhibition, Barcelona, Spain, June 25-28, 2008", "subitem_description_type": "Other"}]}, "item_5_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "Springer"}]}, "item_5_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://doi.org/10.1007/s11548-008-0168-y", "subitem_relation_type_select": "DOI"}}]}, "item_5_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "author"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Hayakawa, Y."}], "nameIdentifiers": [{"nameIdentifier": "38582", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Miyoseta, Y."}], "nameIdentifiers": [{"nameIdentifier": "38583", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yamashita, H."}], "nameIdentifiers": [{"nameIdentifier": "38584", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Sagawa, M."}], "nameIdentifiers": [{"nameIdentifier": "38585", "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": "2016-11-22"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "Hayakawa_S26-S27_final_CARS2008.pdf", "filesize": [{"value": "179.9 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 179900.0, "url": {"label": "Hayakawa_S26-S27_final_CARS2008.pdf", "url": "https://kitami-it.repo.nii.ac.jp/record/7542/files/Hayakawa_S26-S27_final_CARS2008.pdf"}, "version_id": "d2e90f2d-5aae-44d0-8b85-588e5e1f70bd"}]}, "item_keyword": {"attribute_name": "\u30ad\u30fc\u30ef\u30fc\u30c9", "attribute_value_mlt": [{"subitem_subject": "near infrared imaging", "subitem_subject_scheme": "Other"}, {"subitem_subject": "tomo-synthesis", "subitem_subject_scheme": "Other"}, {"subitem_subject": "vascular imaging", "subitem_subject_scheme": "Other"}, {"subitem_subject": "vein pattern", "subitem_subject_scheme": "Other"}]}, "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": "conference paper", "resourceuri": "http://purl.org/coar/resource_type/c_5794"}]}, "item_title": "Superficial vascular imaging system using near infrared radiation and tomo-synthesis algorithm, Tuned-Aperture Computed Tomography", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Superficial vascular imaging system using near infrared radiation and tomo-synthesis algorithm, Tuned-Aperture Computed Tomography"}]}, "item_type_id": "5", "owner": "1", "path": ["10"], "permalink_uri": "https://kitami-it.repo.nii.ac.jp/records/7542", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2013-03-18"}, "publish_date": "2013-03-18", "publish_status": "0", "recid": "7542", "relation": {}, "relation_version_is_last": true, "title": ["Superficial vascular imaging system using near infrared radiation and tomo-synthesis algorithm, Tuned-Aperture Computed Tomography"], "weko_shared_id": 3}
