A multi-modal imaging system (1) includes a fixed gantry (2), and a swivel gantry (8). The fixed gantry (2) supports a first imaging modality. The swivel gantry (8) connects to the fixed gantry (2) by at least three mounting points (10) and supports a second imaging modality. Selectively the swivel gantry (8) includes a swivel frame (16) and at least three mounting points (10) for mounting the fixed and swivel gantries together in an imaging configuration. The at least three mounting points (10) include at least one hinge (14) which permits the swivel gantry to swivel about the fixed gantry into a service configuration.
