Methods and systems for providing thermal insulation in an X-ray tube are provided. The method includes configuring a metallic foam to resist the heat flow in an X-ray tube. The method further comprises configuring the metallic foam for positioning in the X-ray tube to resist heat flow to bearings in the X-ray tube.

Method and system for thermal control in X-ray imaging tubes

A cooling assembly for an X-ray tube with a stationary body comprising a rotating body located at least around a part of the stationary body, and at least one coolant circuit with at least one coolant flowing through it. The coolant circuit is preferably interposed between the rotating body and the stationary body, with the coolant flowing between the rotating body and the stationary body.

Cooling assembly for an X-ray tube

In some embodiments, an anode cooling system for a rotating-anode type X-ray tube includes a heat pipe arrangement comprising an evaporator part coupled to an anode, a condenser part coupled to a bearing of the anode, and a plurality of heat pipes arranged in mutually opposing configuration, in-between the evaporator part and the condenser part, wherein the resultant dynamic force on the heat pipes is substantially zero. In some embodiments, an anode cooling system for an X-ray tube, comprises a first heat pipe configured for operating at a predetermined high first temperature range near an anode, a second heat pipe configured for operating at a predetermined low second temperature range coupled to the first heat pipe, and a heat sink coupled to the second heat pipe, and a liquid metal filled in-between the heat pipes and the anode to transfer heat from the anode to the heat pipe by convection.
