Airway Branch-Angle Reports

Automated measurement of right/left main-bronchus take-off angles from CT airway segmentations (TotalSegmentator trachea label → skeleton → bifurcation-aware direction fit). Each report renders the raw segmentation mesh with no smoothing or decimation, so a bad scan or a bad mask is visible at a glance. Built as an aid for single-lung-intubation planning.

RIGHT 34° @ 236° LEFT 22° @ 131° subcarinal 54° main bronchus R 19 mm / L 22 mm

Bifurcation detected by perpendicular-plane lumen counting; the direction fit stops at the first downstream branch. Arrows and call-outs are placed by deterministic world→pixel projection, not vision.

Cohort — TotalSegmentator example subjects & phantom

Not for clinical decision-making. Research / engineering use only. Subjects shown are TotalSegmentator public example data and a synthetic phantom — no patient data. The raw mesh is shown without smoothing so segmentation defects remain visible; angle epidemiology from this small set should not be generalized.
