Abstract: An x-ray assembly is provided comprising a target shaft and an x-ray target element mounted to the target shaft. A circumferential feature is formed in the x-ray target element. At least one weight element is adapted to be securable in a plurality of positions within the circumferential feature such that the x-ray target element can be balanced around the target shaft.

Abstract: A computed tomography assembly is providing including an x-ray gantry assembly, an x-ray source projecting a beam of x-rays, a detector assembly positioned opposite the x-ray source and receiving the beam of x-rays, and a control mechanism in communication with the x-ray source and the detector assembly. The control mechanism includes logic adapted to: execute at least one scout scan of the object to produce a first scout scan image; generate an elliptical patient model based on the first scout scan image; match the elliptical patient model to a phantom diameter approximation; generate a dose report based on the phantom diameter approximation; and display said dose report on a display in communication with the control mechanism.

Abstract: An x-ray tube window cooling assembly (11) for an x-ray tube (18) is provided. The cooling assembly (11) includes an electron collector body (110) coupled to an x-ray tube window (104) and having a first coolant circuit (112). The coolant circuit (112) includes a coolant inlet (114) and a coolant outlet (122). The coolant outlet (122) directs coolant at an x-ray tube window surface (152) to impinge upon and cool the x-ray tube window (104). The coolant is reflected off the reflection surface (146) as to impinge upon and cool the x-ray tube window (104). A method of operating the x-ray tube (18) is also provided.
