uniGradICON introduces a foundation model for medical image registration, aiming to provide high performance across multiple datasets, zero-shot capabilities for new tasks, and strong initialization for out-of-distribution tasks. The model unifies the advantages of learning-based and conventional registration methods. Trained on twelve public datasets, uniGradICON demonstrates excellent registration accuracy. It uses GradICON regularization to achieve universal applicability while maintaining speed and accuracy. The study evaluates in-distribution, out-of-distribution, and finetuning performance of uniGradICON.
