Abstract:
1. A medical X-ray imaging apparatus comprising a frame part, an X-ray source for producing X-rays, radiation receiving means for detecting radiation transmitted through an object for forming image information, support means for supporting the X-ray source and the radiation receiving means in positions on opposite sides of the object, said support means being connected to the frame part so as to rotate around the axis of rotation, and actuator means for rotating said support means around the said axis of rotation, the apparatus configured for both panoramic imaging and CT imaging, wherein the apparatus comprises as receiving means for CT imaging a fixed camera which comprises a detector for CT imaging, and as receiving means for panoramic imaging a movable camera, which comprises a detector for panoramic imaging, and the movable camera is arranged to be turned about a pivoting axis, to at least one of a first position between the fixed camera and the focus of the X-ray source on the path of the X-rays, where the X-rays are directed at the detector of the movable camera for performing panoramic imaging, and away from the first position to a second position, where the X-rays are directed at the detector of the fixed camera for performing CT imaging, and where the turning movements are arranged so that a ratio of enlargement is substantially optimal for each method of imaging used.
