A method is provided for compensating the settings of a pulsed X-ray system. A current, voltage and intended pulse width settings are selected for the X-ray pulses to be provided. Then, the selected pulse width setting for the set voltage and tube current is compensated, in accordance with stored normalized value or values at a predetermined temperature, taking into account the environmental temperature of the electric circuitry of the X-ray tank. The normalized values are obtained in a calibration step from the actual or effective pulse width and the difference thereof with the intended width, normalizing said value with the temperature of the circuitry providing pulsed voltage and current to the source.

According to one embodiment, an X-ray tube includes a vacuum envelope, a cathode, an anode, and an X-ray transmission assembly. The X-ray transmission assembly includes an X-ray transmission window and an X-ray tube attachment portion. The X-ray tube attachment portion includes a passage port to allow an available X-ray flux to pass therethrough and is opposed to an opening of the vacuum envelope. The passage port has a first shape of a rectangle, an ovally rounded rectangle or a corner-rounded rectangle. The first shape has a longer axis orthogonal to an X-ray tube axis.

An x-ray tube casing is provided which includes a housing having a heat exchanger integrally formed thereon in an additive manufacturing process. The additive manufacturing process allows for tight tolerances with regard to the structure for the casing and the internal passages of the heat exchanger to significantly reduce the size and weight of the casing. The casing additionally includes a fluid distribution manifold that effectively distributes the cooling fluid within the casing to more efficiently provide cooling to the x-ray tube insert disposed within the casing.
