Description
Mert Nahir shows that crooked planes bend angle readings in 3D skull scans. This 2026 paper starts from a simple worry: standard flat slices can distort true spatial angles. Five plastic skulls served as test objects, with four jaw and skull angles marked. Three readers measured each angle by hand gauge, on standard slices, and on reoriented planes.
Hand and reoriented readings matched almost exactly, with bias near zero. Standard slices strayed badly, off by over thirty-six degrees in the worst view. Readers agreed with each other far better under the reoriented method. Nahir argues that aligning the slice to the landmarks' own plane should be a firm rule for surgical planning and implant design.
