The invention relates to a medical computed tomography apparatus which includes a support construction () supporting a substantially ring-shaped O-arm (), which in turn supports imaging means (). The cross-section of the outer cover () of the O-arm in a direction perpendicular with respect to the central axis of said ring-shaped structure () is for its prevailing portion arranged substantially of the shape of an arch of a circle but to comprise a cut, and within the sector covered by the cut the distance from the center of said arch of a circle to the edge of the outer cover () is shorter than within said portion of the outer cover () substantially of the shape of an arch of a circle. As to the examination opening (), it is arranged for its prevailing portion substantially of the shape of an arch of a circle but to comprise an extension, and within the sector covered by the extension the distance from the center of said arch of a circle to the edge of the examination opening () is longer than within said prevailing portion of the examination opening () substantially of the shape of an arch of a circle. The imaging means () are arranged to be moved within the O-arm at different distances from their center of rotation.
