Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we describe a computerized scheme for detection the intracranial unruptured aneurysms
in MRA images. Our computerized scheme consists of 1) blood vessel segmentation, 2) computation of directional
vector field of luminance distribution, 3) aneurysm candidates detection using end-point and distribution characteristics
of the vector, and 4) false positives (FPs) reduction based on linear discriminant analysis (LDA). This method
applied to 24 cases with 32 aneurysms and 26 cases without aneurysms. The sensitivity obtained by our computerized
scheme for the detection of aneurysms was 100% with 4.5 FPs per patients using end-point and distribution
characteristics of the directional vector, and 97% with 1.5 FPs by LDA with three features.
