MIT and Boston Children's researchers build E(3)-Pose to track fetal head motion in MRI
Overview
Researchers at MIT, Boston Children's Hospital, and Inria developed E(3)-Pose, a deep learning model that tracks a fetus's head during prenatal MRI scans to produce a high-resolution 3D brain image.
The model builds the head's left-right symmetry into its architecture to determine the brain's orientation. The team says it was trained mainly on third-trimester fetuses and plans to extend it to second-trimester scans. A paper on the work was presented at the 2026 European Conference on Computer Vision.

AIMIT, Boston Children's Hospital, and Inria researchers have developed E(3)-Pose, a deep learning model that tracks a fetus's head during MRI scans to produce a high-resolution 3D brain image. The model embeds left-right symmetry of the fetal head in its architecture to identify the brain's orientation, and it was presented at the 2026 European Conference on Computer Vision. The team says the model is trained mainly on third-trimester fetuses and plans to extend it to second-trimester scans.
