The invention relates to a controller () for dental imaging of an object. The controller comprises: at least one processor (), and at least one memory () including computer program code (). The at least one memory () and the computer program code () is configured to, with the at least one processor (), cause the controller () at least to: obtain first image data from an optical scanner unit (); obtain second image data from a dental X-ray imaging unit (); produce a first surface model () from the obtained first image data, wherein the first surface model () represents an optical three-dimensional shape of a surface of a first part of the object; and use the first surface model () to process the obtained second image data. The invention relates also to an imaging system (), a method, a computer program (), and a computer-readable medium for dental imaging of an object.

Controller, a dental imaging system, and a method for dental imaging of an object

A system and method of X-ray imaging includes an X-ray emitter that projects X-rays. An X-ray receiver receives X-rays from the X-ray emitter to produce a plurality of projection images. A filter with at least one filter leaf absorbs at least a portion of the X-rays from the X-ray emitter to define a limited field of view within a full field of view, wherein the X-rays are attenuated in at least one attenuated portion of the full field of view. A processor reconstructs a three dimensional image based upon the projection images of the full field of view. The limited field view is located within the reconstructed three dimensional image. At least one corrective parameter is determined from the reconstructed three dimensional image. A three dimensional image is reconstructed based upon the limited field of view and the at least one corrective parameter.

System and method of small field of view x-ray imaging

X-ray imaging systems and methods for exposure control in three-dimensional X-ray imaging include acquiring at least one image with an X-ray emitter and an X-ray receiver. At least one physical characteristic of the object to be imaged is determined from the at least one image. At least one exposure parameter value based is determined based upon the at least one physical characteristic of the object to be imaged. The X-ray emitter and X-ray receiver acquire a plurality of projection images about the object to be imaged using at least one exposure parameter value. A three-dimensional X-ray image is reconstructed from the plurality of projection images.

System and method of small field of view X-ray imaging

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 () 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 () in a memory associated with a display device. When the operator picks up () a new image for examination, the memory is accessed to retrieve () 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 ().
