Real-time surgical segmentation on edge hardware
Intraoperative AI that delineates vascular structures live during surgery, running on an Nvidia Jetson inside the operating theatre.
The challenge
Surgeons operating near major vessels need precise, low-latency visualisation of veins and arteries from ultrasound — imagery that is inherently noisy, low-contrast, and highly variable across patients. Any perceptible delay or cloud-connectivity failure renders the tool unusable in a live procedural context.
Technical scope
- Deep learning segmentation trained on annotated intraoperative ultrasound datasets.
- Architecture balanced for sub-100ms inference on edge hardware without sacrificing segmentation fidelity.
- Advanced preprocessing: speckle reduction, signal normalisation, contrast enhancement tuned for intraoperative noise.
- Full deployment pipeline from training through quantisation and TensorRT optimisation on Nvidia Jetson.
- Robust fallback behaviour engineered for the thermal, power, and reliability constraints of a theatre.
Impact
- Deployed and used in live surgical procedures at a US hospital.
- Demonstrated that edge-deployed deep learning can meet the latency and reliability bar of live surgery.
- Extensible architecture ready for additional intraoperative imaging applications.
