Especially, MDCT is one of the most useful diagnosis systems because it provides a high resolution image to medical doctors. Accordingly, many related image processing techniques are proposed into medical fields for extraction of abnormal area. In the medical image processing field, segmentation is one of the most important problems for analyzing abnormalities. Many related segmentation techniques have been developed for automatic extraction of ROI. In this paper, we propose a new technique for automatic extraction of the multi organs on the breast MDCT images employing the 3D region growing and template matching technique. We apply the proposed technique for extraction of lung and heart region to six CT Cases and satisfactory results are achieved.","subitem_description_language":"ja","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.12.1_93","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.
