Abstract: A medical imaging assembly includes a first imaging plate and a second imaging plate for acquiring a first and a second medical image. A container is configured to receive and hold the first imaging plate and the second imaging plate in a predetermined overlapping orientation. An image reader receives the first and second medical images and produces first and second digital medical images. A processor creates a composite image of the first and second digital images. A method of acquiring a medical image includes identifying an overlapped region of a lower image and an upper image. An alignment transformation is identified by matching the overlapped regions of the upper and lower images. The upper and lower images are aligned based upon the alignment transformation. A composite medical image is created from the upper image and the lower image.

Abstract: A method, device and software for performing tomographic imaging with several offset values in such a way that the first imaging phase is performed by scanning at least a part of the object to be imaged by following the first arc of the first rotating movement to produce the first image information, —the offset of the imaging is changed between imaging phases during imaging, —at least one other imaging phase is performed with at least one changed offset to produce second image information of at least part of the object, —the said image information produced by different offsets is combined into three-dimensional image information.

Abstract: The invention relates to a method for displaying digital grey scale images at a desired tonal value on the screen of a display device. In the method, the operator pre-selects (300) manually, for example on the basis of an image visible on a display screen, a (mean) grey scale level of his/her desire, the values consistent therewith being stored (302) in a memory associated with a display device. When the operator picks up (304) a new image for examination, the memory is accessed to retrieve (306) therefrom the information regarding a target grey scale level and relevant to the present operator, said information being used for automatically calculating an individual transformation function relevant to the present new image and the image is automatically adjusted to an operator-specific target grey scale level (310).

Abstract: The invention relates to a method and system for determining a sharp panoramic image constructed from a group of projection images, especially the invention relates to defining a structure of the panoramic X-ray image of an area of a dentition and of jaws. The structure of a panoramic image to be generated from a group of projection images is determined by at least two crucial parameters, namely parameters of the central surface S of the sharp layer and thickness t(s) of the sharp layer, using penalty function F(S,t), which is at least a penalty function F3(S,t) of low-frequency changes in the computed panoramic image corresponding to the choices S and t(S). After computing F3(S,t) the best center surface and thickness function (in other words the sharpest layer of the panoramic image) is obtained by minimizing said penalty function F(S,t) over parameter space.
