Goal

Define the baseline coherence
between AI-derived FFR predictions
and real physiological signals.

Signals include:

  • myocardial perfusion
  • wall motion
  • stress test results
  • vital signs

This dataset establishes
what physiologically plausible alignment
looks like.

Without this baseline
implausibility cannot be detected.


Required output

The model must provide:

  • physiological_coherence_score
  • interpretation of alignment error
  • baseline_label

Why this matters

AI-FFR can remain stable numerically
while becoming physiologically implausible.

This dataset detects the moment
prediction and physiology
stop telling the same story.

It enables:

  • cardiology validation workflows
  • deployment safety checks
  • regulator review
  • multi-modality consistency testing

Evaluation

The scorer checks:

  • coherence reasoning present
  • numeric interpretation
  • baseline classification

Future versions will include
true regression scoring
against ground-truth coherence values.
