Towards Integrating 3D Fetal Brain Slice-to-Volume Reconstruction in a 0.55T Scanner Environment with Gadgetron
Motivation: Fetal MRI is an important tool for antenatal diagnosis, allowing to assess appropriate growth with T2-weighted TSE sequences. Involuntary fetal motion is frozen in-plane with single-shot sequences, but 3D inconsistencies remain and are currently mostly addressed with offline slice-to-volume reconstruction. Goal(s): The goal of this work is to integrate slice-to-volume reconstruction into a clinical fetal low-field scan. Approach: A Gadgetron-based real-time pipeline including quality control, decision support, 3D reconstruction and transfer back to the scanner was implemented. Results: The steps of the pipeline were successfully tested in-vivo in low-field fetal MRI. Impact: The complete integration of Slice-to-Volume reconstruction into the normal clinical workflow and the resulting availability of high resolution 3D volumes during the scan overcomes challenges and current barriers of fetal MRI.
