Abstract (in Japanese) (See Japanese page) 
(in English) MR image registration (IR) has been used in brain function analysis, voxel-based-morphometry, etc. The conventional IR methods mainly use MR signal based likelihood. However, they cannot prevent miss registration of different gyri because they do not evaluate correspondence of sulci. Also, we cannot directly apply methods for adult brain to neonatal brain because there are large differences in MR signal and sulcal width. This paper introduces a new feature called sulcal-distribution index (SDI) which is calculated from MR signal around the cerebral surface. Next, we propose a non-rigid 3D IR method using flattening with SDI. The likelihood used is mutual information of SDI. The new method evaluates the correspondence of cerebral sulci in IR. And, the method will be effective for neonatal brain in which the accurate delineation of cerebral surface is difficult because the method evaluates the MR signal around the cerebral surface. Results in 3 neonates (modified age; 3-5 weeks) showed the decrease of the angle between vectors of feature point direction.
