摘要:
The present invention is related to a method for deriving shape information of a person's skull and dentition, comprising the steps of : - taking an impression of the person's dentition, - taking a first scan of the person's head, while the person is wearing the impression, - taking a second scan of the impression alone, - combining the scans, - deriving the shape information from the combined scans. Advantageously the method further comprises the step of taking a third scan of the person's head alone without the impression.

The present invention is related to a method for capturing the shape of a dento-maxillofacial object out of volumetric image data of the dento-maxillofacial object. The method comprises the steps of: a) performing a segmentation of the volumetric image data with at least one calculated segmentation parameter indicative of the distinction between the dento-maxillofacial object and its background and derived from a calibration procedure, and b) capturing the shape of the dento-maxillofacial object from the segmented volumetric image data.

The present invention is related to a method for performing a cephalometric or anthropometric analysis comprising the steps of : - acquiring a 3D scan of a person's head using a 3D medical image modality, - generating a 3D surface model using data from the 3D scan, - generating from the 3D scan at least one 2D cephalogram geometrically linked to the 3D surface model, - indicating anatomical landmarks on the at least one 2D cephalogram and/or on the 3D surface model, - performing the analysis using the anatomical landmarks.
