摘要： An x-ray computed tomography apparatus has one anode ring in a vacuum housing surrounding an examination volume, wherein a focus of an x-ray source revolves on the anode ring to expose the examination volume with an x-ray beam from different directions, and a detector system arranged on a rotating frame that can rotate around a system axis. The detector system serves to detect the x-ray radiation exiting from the examination volume, wherein the detector system and the focus can rotate around the system axis synchronously and in the same rotation direction with a rotation angle offset by 180°. The apparatus also includes a computer to process the measurement values acquired by the detector system. The anode ring can be driven such that it rotates around the system axis, and the rotation direction of the anode ring and the rotation direction of the focus around the system axis are opposite while a rotation of the focus around the system axis ensues.

摘要： An x-ray tube has a cathode that generates free electrons; an anode on which the free and accelerated electrons strikes so that x-ray radiation is generated; a cooling channel with coolant flowing therethrough to cool the anode; a vacuum region between the cathode and the anode; and an exit window through which the x-ray radiation exits from the x-ray tube. The anode is fashioned as a transmission anode; with the transmission anode arranged between the vacuum region and the cooling channel, with the cooling channel arranged between the transmission anode and the exit window; so the useful x-ray radiation passes through the coolant.
