Abstract (in Japanese) (See Japanese page) 
(in English) We propose three methods to compensate for the damaged images due to cardiac pulsation artifact in brain to improve the accuracy of orientation distribution function in Q-ball Imaging, with their performance compared using a simulation approach. The average reduction rates in ODF errors after applying the correction methods were 85.0%, 68.1%, and 81.3% when using the neighbor interpolation, the exclusion, and the symmetrical compensation methods, respectively. The proposed neighbor interpolation method may be a useful adjunct to QBI data processing for effective QBI-based tractography.
