Abstract: Systems and methods for obtaining multi-slice images having a total thickness of up to about 160 mm or more in a single gantry rotation in computed tomography or volume computed tomography are described. One embodiment comprises an extended, multi-spot x-ray source for computed tomography or volume computed tomography imaging, comprising: an electron gun capable of producing a plurality of electron beams, each electron beam focused at a predetermined distance and aimed in a predetermined direction; and a plurality of targets positioned to receive the electron beams and generate x-rays in response thereto, each target comprising a predetermined focal spot thereon, wherein each electron beam is synchronized to strike, at an appropriate time, a predetermined target comprising a predetermined focal spot thereon.

Abstract: An x-ray tube assembly is provided comprising a tube casing assembly including a plurality of vertical mount posts. An insulator plate is mounted to the plurality of vertical mount posts such that the insulator plate can translate vertically on the posts. A cathode assembly is mounted to the insulator plate and generates both an eccentric moment and a vertical expansion in response to a cathode power load. A semi-compressible element is positioned between at least one of the vertical mount posts and the insulator plate. The semi-compressible element becomes incompressible at a cathode power threshold such that the vertical expansion is translated into a correction moment countering the eccentric moment.
