| This page provides a precompiled Matlab implementation ("p-code:) of a distortion correction method for diffusion MRI using the interlaced q-space sampling technique. This method uses interlaced phase-encoding directions (IPED) while sampling the q-space, which enables accurate distortion correction without increasing the acquisition time.
