Fuzzy IG is to derive fuzzy granules from information. In the case of medical image segmentation, information and fuzzy granules correspond to an image taken from a medical scanner, and anatomical parts, namely region of interests (ROIs), respectively. The proposed method to granulate information is composed of volume quantization and fuzzy merging. Volume quantization is to gather similar neighboring voxels. The generated quanta are selectively merged according to degrees for pre-defined fuzzy models that represent anatomical knowledge of medical images. The proposed method was applied to blood vessel extraction from three-dimensional time-of-flight (TOF) magnetic resonance angiography (MRA) images of the brain. The volume data studied in this work is composed of about 100 contiguous and volumetric MRA images. According to the fuzzy IG concept, information correspond to the volume data, fuzzy granules corresponds to the blood vessels and fat. The qualitative evaluation by a physician was done for two- and three-dimensional images generated from the obtained blood vessels. The evaluation shows that the method can segment MRA volume data, and that fuzzy IG is applicable to, and suitable for medical image segmentation.<\/jats:p>","DOI":"10.1142\/s0218001400000271","type":"journal-article","created":{"date-parts":[[2003,4,22]],"date-time":"2003-04-22T07:42:39Z","timestamp":1050997359000},"page":"409-425","source":"Crossref","is-referenced-by-count":10,"title":["FUZZY INFORMATION GRANULATION ON BLOOD VESSEL EXTRACTION FROM 3D TOF MRA IMAGE"],"prefix":"10.1142","volume":"14","author":[{"given":"SYOJI","family":"KOBASHI","sequence":"first","affiliation":[{"name":"Department of Computer Engineering,  Himeji Institute of Technology, 2167, Shosha, Himeji, 671-2201, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"NAOTAKE","family":"KAMIURA","sequence":"additional","affiliation":[{"name":"Department of Computer Engineering,  Himeji Institute of Technology, 2167, Shosha, Himeji, 671-2201, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"YUTAKA","family":"HATA","sequence":"additional","affiliation":[{"name":"Department of Computer Engineering,  Himeji Institute of Technology, 2167, Shosha, Himeji, 671-2201, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"FUJIO","family":"MIYAWAKI","sequence":"additional","affiliation":[{"name":"Department of Computer Engineering,  Himeji Institute of Technology, 2167, Shosha, Himeji, 671-2201, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2011,11,21]]},"reference":[{"key":"p_1","first-page":"2","volume":"4","author":"Bortolan G.","year":"1997","journal-title":"IEEE Trans.
