Strong artifacts caused by patient motion during MR
scans affect image quality and clinical evaluation. In
this work, we propose a novel motion correction
framework for free-breathing cardiac MRI with multiple
single-shot Late Gadolinium Enhancement data
acquisition. The resulting motion-corrected image is
recovered through an advanced reconstruction scheme
which incorporates a non-rigid registration. The
performance and effectiveness of our model was tested
off-line through simulation studies. Results achieved by
the present technique show significant reduction in
blurring artifacts while exhibiting sharper geometric
features. This technique holds potential for achieving
higher quality LGE images in challenging patient
populations compared to conventional methods.
