Abstract: Systems and methods utilizing a two-way mirror display for patient self-positioning for dental x-ray image acquisition. The system includes a camera configured to capture an image of a patient, a display, a two-way mirror positioned between a patient location and the display, and an electronic processor. The electronic processor is configured to select, based upon a user input, an operating mode for the display; and based upon the selected operating mode, displaying at least one image on the display. The method includes receiving image data from a camera, identifying at least one facial feature of the patient in the image data, determining if a face of the patient is aligned with at least one anatomical plane based upon the at least one facial feature, and displaying at least one movement guide on a display based upon the determined alignment of the face of the patient.

Abstract: A medical X-ray device arrangement for producing three-dimensional information of an object in a medical X-ray imaging, the medical X-ray device arrangement comprising an X-ray source for X-radiating the object from at least two different directions and a detector for detecting the X-radiation to form projection data of the object. The medical X-ray device arrangement comprises means for modelling X-ray attenuation coefficient of said object using a multiresolution representation, eliminating part of the coefficients in said multiresolution representation to form reduced multiresolution representation, and utilizing said projection data in a regularized reconstruction method based on minimizing the penalty F(f)=?Af?m?2/2+??f?B+?g(f) over the coefficients in the said reduced multiresolution representation to produce three-dimensional information of the object.
