Abstract: A system for remotely venting an expansion bladder employed in a liquid-filled container, such as an outer housing of an x-ray tube. The remote venting configuration provides the expansion bladder with access to atmospheric pressure existing about the x-ray tube so as to enable it to compensate for pressure changes within the liquid-filled container that occur as a result of liquid heating. Further, the remote nature of the bladder venting system enables the expansion bladder to be positioned within a portion of the outer housing that is radiation shielded, while the remote venting portion of the system is positioned in an unshielded portion of the housing. This eliminates the need to perforate the radiation shielding of the outer housing in order to provide atmospheric pressure to the bladder. Further, the remote vent is semi-permeable so as to prevent liquid escape from the system in the event of bladder rupture.

Abstract: A cathode assembly including certain features designed to protect the integrity of a filament contained therein is disclosed. In particular, the cathode assembly is configured to prevent damage to the filament should it inadvertently contact another portion of the cathode assembly. In an example embodiment, an x-ray tube incorporating features of the present invention is disclosed. The x-ray tube includes an evacuated enclosure containing a cathode assembly and an anode. The cathode assembly includes a head portion having a head surface. A slot is defined on the head surface and an electron-emitting filament is included in the slot. A protective surface is defined on the head surface proximate to a central portion of the filament. The protective surface in one embodiment is composed of tungsten and is configure to prevent fusing of the filament to the protective surface should the filament inadvertently contact the protective surface.

Abstract: A cable terminal and clamp system particularly suited for use in an x-ray tube environment. The cable terminal and clamp system includes a cable socket having cable and terminal ports, each of which defines an axis. The cable terminal and clamp system includes a cable clamp that receives at least a portion of the cable socket. The cable clamp and cable socket are configured so that motion of the cable socket, relative to the cable clamp, along the axis defined by the terminal port is unimpaired, while motion of the cable socket, relative to the cable clamp, along the axis defined by the cable port is precluded. A spring interposed between the cable socket and cable clamp biases the cable socket away from the cable clamp along the axis defined by the terminal port. The cable terminal and clamp system thus accommodates thermal expansion of the terminal, while retaining the terminal in an associated receptacle and maintaining alignment of the cable clamp and cable socket.

Abstract: A cathode head is provide that is suitable for use in an x-ray device that includes an anode having a target surface configured and arranged to receive electrons emitted by the cathode head. The cathode head may be constructed of magnetic or non-magnetic material and includes an emitter block carrying a filament that defines a longitudinal axis about which is disposed one or more magnetic coils. The filament is configured and arranged to emit an electron beam that defines a focal spot on the target surface of the anode. The magnetic coil, or coils, disposed about the longitudinal axis defined by the filament generate a magnetic field that enables control of the location of the focal spot on the target surface of the anode.
