Slice-to-volume registration and super-resolution reconstruction is commonly used to generate 3D volumes of the fetal brain from 2D stacks in multiple orientations. The current pipeline requires selecting the stack with minimal motion as a reference for registration. We proposed a motion assessment method that automatically determines the reference stack based on CANDECOMP/PARAFAC decomposition. This method is sensitive to motion across slices compared to other state-of-the-art methods. Combining motion assessment with the existing fetal brain MRI processing pipeline improved the reconstruction quality and the success rate.
