Graphical abstract Highlights ► A new method for reconstruction of 3D fetal brain MRI from 2D slices is proposed. ► The super-resolution reconstruction is interleaved with motion correction. ► Corrupted or misaligned slices are automatically excluded. ► Novel intensity matching is shown to be essential for quality of reconstruction. ► Excellent results for clinical and optimized data.

CLAIMS
CONCEPTS
- 2d slices
The planar MRI slice images used as the input data for reconstruction.
- 3d fetal brain mri reconstruction
The task of building a volumetric fetal brain MRI image from a stack of 2D slices.
Aliases: reconstruction of fetal brain MRI
- clinical data
Real-world fetal brain MRI data collected in a clinical setting for evaluating the reconstruction approach.
- complete outlier removal
A filtering strategy that excludes slices judged to be corrupted or misaligned.
Aliases: outlier removal
- corrupted or misaligned slices
Input slices that are degraded by artifacts or spatial misregistration and may need to be discarded.
- intensity matching
A matching procedure that adjusts image intensities to align slices consistently before or during reconstruction.
- motion correction
A correction step that compensates for subject or slice motion during reconstruction.
- optimized data
Data prepared or tuned for favorable reconstruction conditions in the reported experiments.
- super-resolution reconstruction
A reconstruction step that increases spatial detail beyond the original slice resolution.
Aliases: SR reconstruction
