A gantry of a tomography apparatus has a rotary member that is rotatable around an axis. The rotary member carries at least one component attached to the outside thereto. The component is attached by primary and secondary attachment mechanisms, with only the primary attachment mechanism engaged during normal operation. The secondary attachment mechanism, a T-slot interface in one embodiment, engages for safety and other reasons when the primary attachment mechanism is not functioning properly.

1. A gantry, comprising: a stationary support structure;a rotary member, attached to the stationary support structure, comprising an inside opening for insertion of a subject;a primary attachment mechanism;a secondary attachment mechanism comprising a T-slot interface; anda component;wherein the component can be attached to an outside of the rotary member by the primary attachment mechanism; andwherein the component can be attached to the outside of the rotary member by the secondary attachment mechanism. 2. The gantry of claim 1, wherein: the primary attachment mechanism comprises one or more bolts. 3. The gantry of claim 1, wherein the T-slot interface further comprises: a socket comprising a lip and a base defining a recess bordered by the lip, the socket securable to a first member;a fastener comprising an elongate stem portion securable to a second member and a head slidably insertable into the recess of the socket where the fastener is retained by the lip of the socket; andwherein the first member is the rotary member and the second member is the component, or the first member is the component and the second member is the rotary member. 4. The gantry of claim 3, wherein: the head of the fastener is shaped in a T-shape. 5. The gantry of claim 3, wherein: the head of the fastener is shaped in a dove-tail shape. 6. The gantry of claim 3, wherein: the head of the fastener is shaped in a hook shape. 7. The gantry of claim 1, the T-slot interface further comprising: a T-slot socket integrated into the rotary member; anda T-slot fastener integrated into the component. 8. The gantry of claim 1, the T-slot interface further comprising: a T-slot fastener;a T-slot socket; anda latch for securing the T-slot fastener in place to prevent axial movement of the T-slot fastener from the T-slot socket. 9. The gantry of claim 8, wherein: the T-slot fastener includes an angled edge on an insertion side; andthe angled edge depresses the latch as the T-slot fastener is slid into the T-slot socket. 10. The gantry of claim 8, wherein the latch comprises a spring pin. 11. The gantry of claim 1, wherein: during rotation of the rotary member, the secondary attachment mechanism does not support a weight of the component if the primary attachment mechanism is engaged. 12. The gantry of claim 1, wherein: during rotation of the rotary member, if the primary attachment mechanism is not engaged, the secondary attachment mechanism supports a weight of the component. 13. The gantry of claim 12, wherein: the T-slot interface includes gaps that generate a human-audible noise during movement of the gantry. 14. The gantry of claim 1, wherein: during rotation of the rotary member, if the primary attachment mechanism is partially engaged, the secondary attachment mechanism supports a remaining weight of the component. 15. The gantry of claim 1, wherein: the component is an x-ray tube, a high voltage generator, a heat exchanger, a collimator, an image detector, a circuit board chassis, a balance weight, or a power supply. 16. An annular structure, comprising: a central opening;a primary attachment mechanism;at least one slot to accept the primary attachment mechanism;a secondary attachment mechanism comprising at least one socket;the at least one socket comprising a lip and a base defining a recess bordered by the lip; andwherein the primary attachment mechanism and the secondary attachment mechanism can be used to attach a component and the secondary attachment mechanism does not support a weight of the component if the primary attachment mechanism is engaged. 17. The annular structure of claim 16, the T-slot interface further comprising: a T-slot fastener;a T-slot socket: anda latch for securing the T-slot fastener in place to prevent axial movement of the T-slot fastener from the T-slot socket. 18. The annular structure of claim 17, wherein: the T-slot fastener includes an angled edge on an insertion side; andthe angled edge depresses the latch as the T-slot fastener is slid into the T-slot socket. 19. The annular structure of claim 17, wherein: the latch comprises a spring pin.
