Abstract

A method for automatic recognition of at least one anatomical landmark in a hollow organ of a patient is provided. The method includes providing an image dataset of the hollow organ, establishing or providing a three-dimensional mesh of a surface of the hollow organ from the image dataset, and determining a centerline of the mesh by skeletization. At least one feature is determined for each of a plurality of points on the centerline. A classifier pre-trained on the at least one feature is used for detecting candidates for the at least one anatomical landmark from the plurality of points. The candidates are grouped together with a distance from one another below a threshold. At least one specification determined from the anatomy of the hollow organ is used for confirming or rejecting the candidates for the at least one anatomical landmark. One or more candidates are defined as an anatomical landmark.
