TL;DR: The cerium target x-ray generator is useful in order to perform enhanced K-edge angiography using a cone beam because K-series characteristic x rays from the Cerium target are absorbed effectively by iodine-based contrast mediums.

TL;DR: The high-voltage condensers in a polarity-inversion two-stage Marx surge generator are charged from -50 to -70 kV by a power supply, and the electric charges in the condenser are discharged to an x-ray tube after closing gap switches in the surge generator with a trigger device.

TL;DR: In this paper, a plasma flash x-ray generator is used to generate a weakly ionized linear plasma, consisting of copper ions and electrons, around the fine target, and intense Ka rays are produced us- ing a 10mm-thick nickel filter.

TL;DR: In this paper, the development of a portable X-ray generator with a cerium-target tube and its application to angiography is described, where negative high voltages are applied to the cathode electrode in the Xray tube, and the tube voltage and current are regulated by the controller or the computer.

TL;DR: In this paper, a cerium target plasma flash x-ray generator is used to perform high-speed enhanced K-edge angiography using cone beams, because K-series characteristic x-rays from the cerium targets are absorbed effectively by iodine-based contrast mediums.
