Abstract:
1. A device to support and tilt a gantry of a computed tomography apparatus relative to a pedestal, said device comprising: a first gantry part and a second gantry part, said first gantry part being rotationally mounted in said second gantry part so as to rotate in a plane in said second gantry part, around a system axis that proceeds perpendicularly through said plane; a tilt axle comprising a first tilt axle part attached at opposite ends thereof to opposite sides of said second gantry part, said tilt axle further comprising a second tilt axle part that annularly surrounds said first tilt axle part with a separation therebetween, and that is attached to said pedestal; a magnetic bearing configured to magnetically support said second tilt axle part relative to said first tilt axle part, and thereby also support said second gantry part relative to said pedestal; and an electromagnetic drive configured to electromagnetically tilt said second gantry part, and thus also said first gantry part and said plane, relative to said pedestal of said gantry around a tilt axis that proceeds through said tilt axle and that proceeds perpendicularly to said system axis.
