AngioAI Pro — Coronary Angiography Analysis

Upload a coronary X-ray angiography (XCA) video. The pipeline:

Step	Module	Notes
1	Keyframe extraction	contrast × sharpness score
2	Stenosis detection	3 × YOLOv8-seg ensemble with weighted mask fusion
3a	Binary vessel mask	ResUNet
3b	Coronary segments	25 SYNTAX segments (YOLOv8-seg)
4	QCA + FFR estimate	diameter stenosis on the measured branch; QFR = 1 − (0.33·DS + 0.60·DS²)
5	SYNTAX (anatomical)	segment weights × lesion multiplier, lesions ≥ 50 % DS

Held-out ARCADE stenosis test set (300 images): precision 0.55, recall 0.76, F1 0.64 (mask IoU ≥ 0.3), 0.80 false positives per image.

Checkpoints are loaded from the private model repo MuhammadAdil63/angio-ai-checkpoints (Space secret HF_TOKEN).

Research use only. Not a medical device and not for clinical diagnosis. Not validated on non-ARCADE data or on normal angiograms.
