Abstract: An x-ray source includes an optical communications link to provide a galvanically isolated communication between a system controller and a gun controller. In specific examples, the link is provided through one or more fibers. In addition, the gun controller is preferably remote programmed by the system controller during startup. This addresses the problem of reprogramming a processor in a hard to access location/environment. A watchdog timer is also useful for the gun digital processor of the gun controller.

Abstract: A bearing structure for an X-ray tube is provided that includes a journal bearing shaft with a radially protruding thrust bearing encased within a bearing sleeve, one of which rotates relative to the other. The stationary component, e.g., the journal bearing and/or the thrust bearing includes at least one vent groove formed therein that improves the ability of the journal bearing structure to enable gases trapped by the liquid metal within the bearing assembly to escape through the vent groove to the exterior of the X-ray tube. By adding a strategically located channel or vent groove of sufficient size in at least one of the journal bearing or the thrust bearing, the pressures resisted by the seal created between the liquid metal and the vent groove(s) in the bearing components is significantly reduced, allowing escape of the gases to avoid detrimental effects to the operation of the X-ray tube, while maintaining the load carrying capacity of the bearing assembly.
