A diagnostic imaging system ( 10 ) includes an x-ray source ( 16 ), which is rotated around an examination region ( 20 ) on a rotating gantry ( 14 ). A subject, disposed on a couch ( 30 ), is translated longitudinally through the examination region ( 20 ). The imaging system is standardized such that a common subassembly is adapted to receive a bore ( 24 ) of any selectable diameter. The common subassembly includes a stationary gantry ( 12 ) and a bearing race ( 52 ) supported by bearing members ( 50 ). Standard motor modules ( 28 ), standard power slip ring modules ( 56 ), and standard information transmission modules ( 58 ) are disposed about the race ( 52 ). The number of the standard modules ( 28, 56, 58 ) is specified by a user.
