Research Summary: Clinical diagnosis of craniofacial syndromes normally requires expert knowledge, and most AI-based analysis tools work from 2D photographs, analyzing texture and color rather than shape, which limits their use with medical imaging modalities like ultrasound, MRI, or CT. Researchers from Great Ormond Street Hospital, Imperial College London, Alder Hey Children’s Hospital, and Necker Hospital in Paris built a research framework using Convolutional Mesh Autoencoders (CMAs), a shape-based successor to 3D morphable models (3DMMs) that works directly from surface topography rather than texture, making it usable across both photography and medical imaging. A single model was trained on a combined pool of real-world 3dMD facial and head scans, drawn from the datasets underlying the LSFM and LYHM shape models, alongside CT-derived meshes of infants and children with three genetically distinct craniofacial syndromes, Apert, Crouzon, and Muenke.
