Researchers have developed a novel method for 4D medical image interpolation, a technique crucial for analyzing dynamic anatomical changes in applications like cardiac MRI and thoracic CT. The new approach, termed Phase-Aligned Finite-Fourier Periodic Deformation, utilizes a finite Fourier basis to embed near-periodic motion patterns directly into the deformation space. It also incorporates a phase-aligned temporal reparameterization to better model non-uniform motion progression, mapping normalized time to a latent motion phase based on deformation intensity. Experiments on ACDC and 4D-Lung datasets demonstrate that this method achieves state-of-the-art performance, producing anatomically plausible and coherent intermediate volumes from sparse observations.
