AI-Powered CT Stroke Analysis
Automated perfusion parameter maps, threshold-based volumetrics and a 10-region ASPECTS summary from CT Perfusion — quantitative measurements presented for interpretation by qualified healthcare professionals.
Processing Pipeline
Fully automated from DICOM ingest to clinical report.
Pipeline
- 1Automated DICOM ingestion and preprocessing
- 2Brain extraction, CSF removal and motion correction
- 3Arterial and venous reference detection
- 4Perfusion map computation
- 5Core/Penumbra volumetrics and ASPECTS scoring
- 6Structured clinical report generation
Perfusion Maps Generated
- CBF (ml/100g/min, 0-150)
- CBV (ml/100g, 0-12)
- MTT (seconds, 0-30)
- Tmax (seconds, 0-20)
- Relative CBF (% contralateral)
- Core mask (rCBF<30%) & Penumbra (Tmax>6s)
Clinical Metrics
Low-rCBF Volume (mL)
Tissue volume below the configured rCBF threshold (default 30%)
Elevated-Tmax Volume (mL)
Tissue volume above the configured Tmax threshold (default 6s)
Volumetric Ratio
Ratio of the two volumes above
CT-ASPECTS
10-point regional summary, 10 MCA regions
Hypoperfusion Intensity Ratio
Volume(Tmax>10s) / Volume(Tmax>6s)
CBV Index
rCBV within the Tmax>6s region
Clinical Applications
