Synopsis

Keywords: Motion Correction, Brain, MRI acquisitionHead motion monitoring and compensation during MRI is essential to imaging quality and success rates of acquisition. MoCAP is a novel real-time head motion monitoring and correction technique utilizing structured light to perform prospective motion correction by adjusting MR gradient. We perform effectiveness and reliability assessment on MoCAP in structural and functional MRI. MoCAP can significantly improve quality of the two modalities, reducing motion artifacts and enhancing validity and reliability of post-processing results. MoCAP is promising in the MRI field for special populations like children and patients with difficulty in keeping still during scan.
