    摘要: An x-ray tube includes an anode comprising a focal track and a cathode assembly configured to emit an electron beam toward a focal spot on the focal track. The x-ray tube also includes a controller configured to wobble the electron beam among a plurality of focal points in a direction tangent to the focal track. The plurality of focal points includes at least one focal point that is bounded by a pair of boundary focal points. The controller is further configured to delay a wobble of the electron beam away from the at least one focal point for a pre-determined amount of time.

    摘要: A slotted window collector assembly for an x-ray tube having an anode and a cathode includes a collector having an anode side and a cathode side, which opposes the anode side. The anode side and the cathode side define an internal bore there between for receiving x-rays from the anode. The slotted collector further includes a window side common to both the anode side and the cathode side and having a window coupled thereto, wherein a window aperture is defined extending from the window to the internal bore. Within the collector assembly, a slot is defined intersecting the window aperture and extending trans-axially thereto and beyond a set length. The slot also extends circumferentially with the window such that plastic strain on the window and heat transferred to the window are reduced.
