description The invention relates to a cathode for an X-ray tube and a corresponding method for assembly. The cathode comprises a filament (22), at least two support structures (21), a body structure comprising arecess for the filament. The filament is provided to emit electrons towards an anode in an electron emitting direction (25). The filament is held by the support structures, which are fixedly connected to the body structure. The filament is totally recrystallized before assembly and has an at least partial helical structure. The support structures comprise a reception end (24) for releasably receiving two ends of the filament by means of a locking mechanism and the complete alignment of the filament and the recess is given by the geometry of the filament, the at least two support structures and the body structure which comprises a recess for the filament. An improved and facilitated cathode assembly with increased reliability of the precision of the positioning in operation is achieved. 本发明涉及用于X射线管的阴极(10)和相应的组装方法。
