Abstract

Small amount of iodine contrast material in the small vessels can be efficiently detected by monochromatic synchrotron radiation (x-ray) tuned at just above k-edge of iodine (33 KeV). However, the serious disadvantage of the system is a high cost for the facility to obtain synchrotron radiation (x- ray). We are trying to apply a plasma x-ray source for this purpose. In this system, the high voltage main condenser is charged up to 60 KeV by a power supply. The electric charges in the condenser are discharged to the tube after triggering the cathode electrode. For a cerium plasma target, a highly intensified K(alpha) and K(beta) characteristic x-ray of cerium (34.6 KeV and 38.3 KeV) was produced, as bremsstrahlung x-ray was absorbed and converted into fluorescent x-ray. Plasma x- ray source might be an alternative of monochromatic synchrotron radiation for small vessel radiography.
