A fluid-cooled compact x-ray system includes a compact x-ray tube and a coolant channel coupled thereto. The compact x-ray tube includes a tube housing defining a longitudinal axis, and an electron source in the tube housing and coaxial with the tube housing. The electron source is configured to generate an electron beam. The compact x-ray tube also includes an anode coaxial with the tube housing, the anode defining a plane perpendicular to the longitudinal axis and including a target material, and an electron focusing mechanism in the tube housing and configured to focus and accelerate the electron beam to the anode. The target material of the anode generates a high-energy x-ray beam as a result of bremsstrahlung interaction. The anode defines an interface between the tube housing and the coolant channel. The coolant channel includes a channel housing, and a coolant configured to dissipate heat from the anode.
