Abstract: A method for improving the accuracy of a digital medical model of a part of a patient, the method includes obtaining a set of at least 2 medical images of the patient, where an element including 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, the 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.

Abstract: A method for generating a panoramic image of a patient includes 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 a computer-implemented method of denoising dental images, comprising: obtaining a training set of images of a first type, comprising noisy images and true images, where the noisy image is the true image with generated noise; training at least one neural network on the training set; and denoising a dental image of the second type through the trained neural network.

Abstract: A method for reconstructing at least a first and a second independently moving body from one 3D tomography scan includes 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: A method for determining the position and/or orientation of at least one sensor system relative to the base structure of a scanning system during scanning of an object, the method includes obtaining one or more tracking images using one or more cameras, where the cameras are in a fixed position with respect to the sensor system; and determining from the one or more tracking images the position and/or orientation of the sensor system relative to the base structure at a given time.
