TotalSegmentator traces airways to lung nodules in 38s, single GPU
MaziyarPanahi · x · 2026-11-10
A hands-on demo of TotalSegmentator (open-source, Apache-2.0, from University Hospital Basel): one click routes through a patient's airways to reach a lung nodule — airways, arteries and veins traced in 38 s, walking 9 branches deep down the airway tree and stopping 5 mm before the nodule, all on a single GPU.
Validation on 20 public scans (LIDC-IDRI): 8 within 10 mm of the nodule, median 14 mm — promising but not perfect. The author notes some scans are in the training data; research use only, not medical advice.
