An imaging system (500) includes an annular shaped rotating gantry (504) having an aperture (501) and configured to support at least a radiation source, wherein the rotating gantry rotates about a rotation axis (508) around an examination region, and wherein the rotation axis is located within the aperture in a center region (508) of the examination region. The imaging system further includes a stationary gantry (502), configured to rotatably support the rotating gantry. The stationary gantry includes a gantry base (516), an annular shaped tilt frame (518) that rotatably supports the rotating gantry, and a tilt system (520) affixed to and between the gantry base and the tilt frame, wherein the tilt system defines a tilt axis (522) of the stationary gantry, the tilt axis is located between the gantry base and the rotation axis, and the tilt frame tilts about the tilt axis. |
