In the field of abdominal CT images, it is very important to understand blood vessel structures of a patient before operation. On the other hand, temporal subtraction method attempt to remove normal structures in the CT images, so that abnormalities can be observed more clearly to the medical doctor. With the subtraction techniques, image warping is very important. In order to achieve a good performance, elastic matching technique is applied to temporal subtraction method. In this paper, we apply temporal subtraction method with elastic matching technique to abdominal CT images in order to detect the blood vessel region. In this method the temporal subtraction is applied between successive phases. The proposed technique is applied to three abdominal CT images. And we perform 3-D displaying of extracted blood vessels by using a SSD and can perform the usefulness of proposed technique.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_21_publisher_7":{"attribute_name":"出版社","attribute_value_mlt":[{"subitem_publisher":"バイオメディカル・ファジィ・システム学会","subitem_publisher_language":"ja"}]},"item_21_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.24466/jbfsa.10.2_65","subitem_relation_type_select":"DOI"}}]},"item_21_rights_13":{"attribute_name":"著作権関連情報","attribute_value_mlt":[{"subitem_rights":"バイオメディカル・ファジィ・システム学会.
