Cerium target X-ray generator enhances K-edge angiography

"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," according to scientists in Japan.

"The X-ray generator consists of a main controller, a unit with a Cockcroft-Walton circuit and a fixed anode X-ray tube, and a personal computer," explained E. Sato and colleagues at Iwate Medical University. "The tube is a glass-enclosed diode with a cerium target and a 0.5 mm-thick beryllium window."
