Abstract: Disclosed is a method for reconstructing at least a first and a second independently moving body from one 3D tomography scan, comprising performing a movement of the first body relative to the second body, obtaining the movement, obtaining a 3D tomography scan of the first body and the second body during the movement, and reconstructing a first 3D model of the first body and a second 3D model of the second body by applying the recorded movement to the 3D tomography scan. This has the effect that reconstruction of several 3D tomography scanned bodies is possible during motion of the scanned bodies.

Abstract: Disclosed is a method for generating a panoramic image of a patient, the method comprising: - obtaining a digital 3D surface representation of at least a part of the patient's teeth; - using the obtained digital 3D surface representation to define a customized path following the arch form of the patient's teeth; - obtaining a plurality of x-ray images of at least a part of one of the patient's jaws and/or teeth; and - generating the panoramic image of the patient using the customized path.

Abstract: Disclosed is surface guided cropping in volume rendering of 3D volumetric data from intervening anatomical structures in the patient's body. A digital 3D representation expressing the topography of a first anatomical structure is used to define a clipping surface or a bounding volume which then is used in the volume rendering to exclude data from an intervening structure when generating a 2D projection of the first anatomical structure.

Abstract: Disclosed is an optical coherence tomography scanner and a method for recording sub-surface scans of an object, wherein a position encoder is arranged in the path of the probing beam of an interferometric system. The encoder pattern is detected in a sequence of A scans at generated for different probing beam positions on the scanned object, the probing beam position and/or inclination for at least one A scan of said sequence of A scans is deducing based on the detected encoder pattern, and the sub-surface scan of the object is generated based on the sequence of A scans taking into account the deduced probing beam position and/or inclination.

Abstract: Disclosed is a method for improving the accuracy of a digital medical model of a part of a patient, the medical model comprising at least 2 medical images recorded with a medical imaging device, the method comprising: - obtaining a set of at least 2 medical images of the patient, where an element comprising a predefined geometry and/or predefined information was attached to the patient during the recording of the medical images; - obtaining at least 2 tracking images taken with at least one camera having a known positional relationship relative to the medical imaging device, said tracking images depicting at least part of the element; - determining any movement of the element between acquisition of the at least 2 tracking images; and - generating the digital medical model from the acquired medical images, wherein the determined movement of the element is used to compensate for any movement of the patient between the acquisition of the medical images.
