BitsXLaMarató — Aorta
Winning project of the BitsXLaMarató 2022 hackathon. Run the aorta pipeline live: abdominal ultrasound → Mask R-CNN segmentation → 3D mesh reconstruction → aortic diameter estimation.

Simulated inference
Browser mock · real B-mode frame
Mimics the real Mask R-CNN inference on a B-mode frame from the rat aorta dataset. The red overlay is a browser mock, not model output.
Diameter explorer
Educational risk visualization
The app estimates aortic diameter from segmented contours. Drag to see how a measurement maps to educational risk buckets — not for diagnosis.
Max outer diameter28 mm
Typical range
Many adult abdominal aortic diameters fall well below 30 mm.
