MOTION DETECTION AND CORRECTION METHOD FOR MAGNETIC RESONANCE DIFFUSION WEIGHTED IMAGING (DWI)
摘要
<p>A magnetic resonance imaging system (1) includes at least one processor (28) configured to receive (48) diffusion weighted imaging data based on a diffusion weighted imaging sequence with magnetic gradient fields applied in different directions and with different b-values. The at least one processor (28) is further configured to detect (50) motion corrupted data present in the received imaging data based on a comparison of data redundant in the received data, and substitute (52) alternative data for detected motion corrupted data.</p>
