Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for manufacturing a cathode filament for an X-ray tube and an X-ray tube formed by the method wherein the filament has at least two legs and one body, the filament being a single-piece filament. SOLUTION: This method comprises: a process for spraying at least one kind of material on a support body by plasma spraying or by another deposition technique to obtain the filament molded on the support body; and a process for separating the obtained filament from the support body. The obtained filament has a variable thickness (d, D) and a variable composition. The thicknesses of the legs and of the body as well as the composition of the filament can be modified according to the user's request. This application relates to an X-ray tube having a cathode filament like that. COPYRIGHT: (C)2005,JPO&NCIPI
