• Learns voxel‑wise amplitude, phase, potential as complex wavefunction.
• Achieves stable long‑horizon 4‑D predictions, reducing drift.
• Interpretable latent fields link to physical dynamics.
• Demonstrated on synthetic benchmarks; poised for clinical use.

Pulse Analysis

Accurate spatiotemporal forecasting has long been a bottleneck for fields that rely on three‑dimensional data streams, from medical imaging to geophysics. Traditional deep‑learning predictors often treat time as another dimension, leading to cumulative errors and unrealistic deformations when extrapolating far beyond the observed window. By integrating a physics‑based prior—specifically the Schrödinger equation—researchers provide a mathematically grounded scaffold that guides the network’s evolution, ensuring that predictions respect underlying physical constraints while retaining the expressive power of convolutional architectures.

The core of the new framework is a complex‑valued wavefunction constructed from voxel‑wise amplitude, phase, and potential fields. These latent components are not black‑box embeddings; phase directly encodes transport dynamics, amplitude reflects structural intensity, and the learned potential governs interaction forces. A differentiable, unrolled Schrödinger time stepper advances this wavefunction forward, acting as a natural regularizer that suppresses drift and stabilizes long‑horizon forecasts. This interpretability offers researchers diagnostic insight and opens pathways for hybrid models that combine data‑driven learning with biomechanical simulations.

For the medical‑imaging market, the implications are immediate. Real‑time MR‑guided radiotherapy, for instance, demands predictions on the order of hundreds of milliseconds to compensate for system latency. The presented architecture delivers anatomically consistent deformation forecasts within that window, potentially improving targeting accuracy and patient outcomes. Beyond healthcare, the method could accelerate material‑science simulations and seismic modeling, where reliable four‑dimensional predictions are equally valuable. As the approach moves from synthetic benchmarks to clinical datasets, it promises to set a new standard for stability and interpretability in AI‑driven spatiotemporal forecasting.
