To present a comprehensive method for correcting motion artifacts and distortion in diffusion-weighted MRI images.
Implemented a mutual information-based registration technique for image alignment.
Developed a spatial transformation model correcting for eddy current-induced distortion and rigid body motion in three dimensions.
Optimized all parameters simultaneously to improve registration speed and accuracy.
Achieved significant improvements in the accuracy of diffusion tensor imaging data.
Registered images showed enhanced quality with reduced artifacts from motion and distortion.
Signal amplitude corrections accounted for object size variations due to distortion.
