Abstract

Patient motion during magnetic resonance imaging (MRI) introduces artifacts that can render the image non diagnostic. A novel approach is proposed to correct for artifacts caused by translational motion. Initial simulation results show the algorithm to be effective in the presence of signi´Čücant noise. Potential applications include use in clinical MRI while similar techniques could be applied to MRI diffusion imaging.
