The invention relates to a medical computed tomography imaging apparatus which is especially designed to enable cranial imaging. The structure of the apparatus includes a gantry () comprising imaging means () and a positioning support () which positioning support () is arranged to position the patient's cranium for exposure such that, when exposed, the cranium is scanned by a radiation beam substantially parallel with a plane formed by the facial area of the cranium and substantially only in an area on the facial side of the cranium.

CT apparatus for imaging cranial anatomies

The invention relates to a medical computed tomography imaging apparatus which includes a support construction () which is arranged to support a substantially ring-shaped structure () supporting x-ray imaging means (), which x-ray imaging means () are arranged within said substantially ring-shaped structure supporting the imaging means () and movable within said substantially ring-shaped structure supporting the imaging means (), which ring-shaped structure () supporting the imaging means () includes an examination opening (), whereto the object to be imaged can be positioned for imaging. According to the invention, at least one display () is arranged to the apparatus. The display is arranged in functional connection with at least one video camera (), which at least one video camera () is arranged in connection with said ring-shaped structure () and as aimed, or so that it can be aimed inside said examination opening ().

Medical computed tomography imaging apparatus

Mammography imaging apparatus according to the invention contains e.g. an essentially vertically standing body part and an arm structure in connection with it, being turnable with respect to a horizontal rotating axis, a radiation source on one hand and image data receiving means on the other hand being located at essentially opposite ends of the arm structure. The arm structure includes at least two arm parts orientating essentially parallel and means for changing mutual orientation of at least the first and the second of the said at least two arm parts, first means for turning the said first arm part around a horizontal axis and second means arranged to the said second arm part with help of which, when turning the said first arm part, it is possible both to maintain orientation of the said second arm part with respect to the said first arm part and to turn the said second arm part in a different direction and/or at a different angular velocity with respect to the movement of the said first arm part.
