An imaging system (100) includes an annular bearing (404) with an iso-center (406). The annular bearing includes a stationary side (4041) and a rotatable side (4042) with at least one alignment feature (420). The imaging system further includes a rotating gantry (410) mechanically coupled to the rotatable side. The imaging system further includes an imaging component (412, 416, 418). The imaging components includes at least one complementary alignment feature (602, 804) that is complementary to the at least one alignment feature (420, 802, 1200) of the rotatable side. The rotating gantry is between the imaging component and the rotatable side, and the imaging component is aligned with the iso-center through the at least one alignment feature and the at least one complementary alignment feature. |
