Abstract
A computer-implemented method of segmenting computed tomography images of teeth comprising obtaining a first 3D digital model representing crowns of erupted teeth of a first jaw and a 2D CT image sequence of the first jaw; using a local image classification model to select from the sequence, for each erupted tooth, a 2D CT image from which segmentation of the erupted tooth starts, the local image classification model being a trained deep neural network for classifying a local 2D CT image as crown or root; obtaining position and coverage information of each erupted tooth based on the first 3D digital model; and using the position and coverage information and a local image segmentation model to segment local images of the erupted tooth starting from the selected 2D CT image towards the crown and the root of the erupted tooth to obtain a binary mask image sequence of the tooth.
