The idea in plain language.
Combine a learned image prior with the measurement process available at reconstruction time.
How it works
A score model first learns the distribution of medical images. At reconstruction time, its sampling procedure is guided both by that learned prior and by consistency with observed measurements. Because the measurement model is introduced at this stage, the method can be applied to different measurement processes without learning a separate direct mapping for each one.
What to keep in mind
This is a research reconstruction method, not evidence of clinical readiness. A plausible reconstructed image may contain errors and requires task-specific validation.
