Problems solved by technology

[0006] Some recently designed CT devices are multi-purpose devices supporting more than one imaging modality, on the other hand this tends to increase the Complexity
Furthermore, the weight of the device may then increase, and some modifications may, for example, create new challenges related to positioning the patient for exposure
[0007] For example, in U.S. Patent No. 7,945,012, various imaging modes of a CT imaging system have been conceived, but no specific and detailed structural embodiments are taught to achieve the motions required for the imaging modes

Abstract

The invention relates CT imaging apparatus comprising a longitudinally extending frame part, a support construction for an X-ray source and an image detector extending from the longitudinally extending frame part and a driving mechanism arranged to move the X-ray source and the image detector about a rotation axis 13. The support construction includes a guiding construction configured to enable laterally moving at least either of the X-ray source and the image detector in relation to the support construction wherein the range of the lateral movement of the at least either of the X-ray source and the image detector comprising a base position and a first and a second extreme position.

Description

technical field [0001] The invention relates to a computed tomography device. In particular, the structure of the device according to the invention is suitable for use in the context of dental and medical cone beam computed tomography (CBCT) imaging devices. Background technique [0002] Computed tomography (CT) is a type of X-ray imaging in which a volume to be imaged is irradiated from different directions, and based on the image information thus acquired, a desired two-dimensional or three-dimensional image can be reconstructed. [0003] Conventional CT devices are large and heavy and they are usually floor mounted. A patient is positioned for imaging within an examination opening of the device and is typically imaged on a horizontally extending and laterally movable examination platform. [0004] Since the development of cone beam computed tomography (CBCT), which uses the slower rotational speed of the imaging device, devices have been developed that weigh less than m...
