Computer Vision News Computer Vision News 30 What is TUS-REC Challenge: Held at MICCAI in 2024 and 2025, the TUS-REC Challenge is the world’s first publicly available international benchmark for reconstructing 3D ultrasound volumes without any tracking hardware — no bulky, expensive optical or electromagnetic trackers. Instead, participants must reconstruct a full 3D ultrasound volume by “stitching together” a stream of 2D ultrasound slices, inferring how the probe moved in space based solely on what each ultrasound frame shows. It’s a bit like navigating a plane without radar — relying only on what you can see to work out how you’re moving. Why it matters: Imagine trying to take a panoramic photo with your phone, but the phone doesn’t record how you moved it. You’d end up with lots of separate pictures, but no way to stitch them together into a smooth, full scene. MICCAI Challenge Qi Li is a final-year PhD student in Medical Imaging at the Hawkes Institute, University College London, supervised by Yipeng Hu and Tom Vercauteren. Over the years, Qi has made a long journey through the world of trackerless 3D freehand ultrasound reconstruction. More recently, she has ventured into uncertainty quantification in image segmentation. If you share the same interest and ambition, talk to her now while she is still in the postdoc market, especially if your opportunity is near London! As the lead organizer of the TUS-REC Challenge series, Qi accepted our invitation and is very excited to share how this initiative has advanced the field by providing high-quality benchmarks, fostering collaboration, and accelerating progress in trackerless freehand ultrasound reconstruction.
