DEVICE FOR REDUCING AN ARTIFACT OF A HIGH LEVEL DIFFUSION MAGNETIC RESONANCE IMAGE AND A METHOD THEREOF CAPABLE OF REDUCING A FLUCTUATION PHENOMENON IN A GRADIENT DIRECTION

摘要

PURPOSE: A device for reducing an artifact of a high level diffusion magnetic resonance image and a method thereof are provided to correct image shift in a phase encoding direction by considering factors in the phase encoding direction of a motion matrix.;CONSTITUTION: A composing unit(310) composes a diffusion q-space matrix and a correcting unit(320) corrects image shift in a phase encoding direction on the diffusion q-space matrix. A recomposition processing unit(330) applies the image shift to recompose a q-space of DSI(Diffusion Spectrum Imaging). A tracking processing unit(340) processes DSI fiber tracking by using the q-space. The correcting unit inserts a non-diffusion component into a b-matrix related to the q-space matrix and processes motion calculation and registration by using a non-diffusion image.;COPYRIGHT KIPO 2013;[Reference numerals] (300) Device for reducing an artifact of a high level diffusion magnetic resonance image; (310) Composing unit; (320) Correcting unit; (330) Recomposition processing unit; (340) Tracking processing unit
