We present a fast learning-based algorithm for deformable, pairwise 3D medical image registration. [...] Key Method Given a new pair of scans, we can quickly compute a registration field by directly evaluating the function using the learned parameters. We model this function using a CNN, and use a spatial transform layer to reconstruct one image from another while imposing smoothness constraints on the registration field.Expand
