Keywords: Motion Correction, Motion Correction, PROPELLER
Motivation: PROPELLER MRI has been widely used to mitigate patient motion; however, conventional approach is not very robust, and does not address inter-slice misalignment that tends to occur on few moving patients.
Goal(s): Develop new robust inter-blade and inter-slice motion correction technique.
Approach: We propose a novel inter-blade and inter-slice motion correction reconstruction technique for PROPELLER MRI using volumetric calibration scan as reference.
Results: The results show large improvement brought by the proposed method compared to convention Motion Correction on both in-plane motion artifact mitigation and inter-slice alignment.
Impact: Reducing repeat scans due to patient motion, hence, increase patient throughput.
Enable scanning patient who cannot keep still in the scanner, such as pediatric patients.
