Alongside the Atlas C1 cabinet, where the two computers responsible for image acquisition, processing, storage, transmission, and display live, every GE Innova cath/angio lab has a second cabinet called the Atlas C2.
While the Atlas C2 doesn't handle any images itself, it's still home to some vital functions that make the work physicians do with their cath/angio labs possible. Below we're going to break down which components are stored inside the Atlas C2 cabinet and what they do.
At the top of the cabinet is a module called the positioner (pictured right, item 1). This is made up of a series of boards and cables that send the signals for all the motions of the lab's gantry and detector and monitor the position of the patient table. There are several vertical boards that are labeled A1-A6. Each board controls a different aspect of the lab's movement. On a fun note – if you hear your service engineer refer to the “roadrunner”, they mean the CPU board in slot A1, not the cartoon character. The name is a colloquialism among field service personnel.
Given its nuts-and-bolts, utilitarian function, the bottom compartment of the Atlas C2 cabinet isn't as exciting to talk about as its more high-tech counterparts up top or in the Atlas C1, but nothing gets done without it. This portion is often called the "bulkhead" (pictured right, item 2). The bulkhead is a bundle of DC power supplies and cables that power the boards in the positioner. This is also where the ports are for the interconnect cables that link the cabinet to the rest of the lab.
If you experience trouble with your cath lab's movement, there's a good chance the problem originated somewhere in your Atlas C2 cabinet. Fortunately, the Innova line's immense popularity has made replacements for these parts relatively easy to find.
