Quantitative Analysis of the Efficacy of Gradient Table Correction on Improving the Accuracy of Fiber Tractography

摘要

Purpose: Several groups suggested that the gradient table of a DTI data set should be reoriented to compensate for head motion. Although the effects of this correction were demonstrated qualitatively, its efficacy was not demonstrated quantitatively to date. The main goal of this study was to investigate the efficacy of gradient table correction on improving the accuracy of fiber tractography.
