3D vascular reconstruction from 2D ultrasound

A pilot on synthetic data. Parametric vessels were cut into simulated ultrasound frames, a segmentation network was trained on those frames, and each test vessel was rebuilt in 3D from the network's output and scored against the vessel it came from.

Build a vessel, then scan it.

The pilot's generator and frame simulator, running in your browser. Shape a vessel within the ranges the training set was drawn from, turn it, and move the probe along it.

Drawn to scale. The teal square is the probe's 20 mm field of view.
