About RiSAT
Rapid ischemic Stroke Assessment Tool
What this tool does
RiSAT takes structured clinical findings as input — symptoms, exam findings, imaging features — and returns a ranked list of candidate vascular territories and stroke syndromes. Results are displayed alongside an interactive 3D cerebrovascular model that highlights the most likely affected vessels.
Who it is for
This is a clinician-facing research and demonstration prototype developed for early research workflows.
Clinical model
The current active clinical model is version 1.2.0. It uses hierarchical vascular grouping with MCA depth-ladder pruning to rank candidate territories by supporting evidence count.
A Bayesian probability model is planned for a future version pending finalization.
