ABSTRACT:
An X-ray apparatus includes an X-ray source with an X-ray tube (2) arranged in a protective tube housing (1) and a filament converter which is connected to the cathode (3) of the X-ray tube (2) and accommodated in the protective tube housing (1). Because of its volume, the filament converter usually cannot be accommodated in the protective tube housing (1) of conventional X-ray apparatus unless major structural modifications are made. However, the use of attenuated high-voltage cables at the cathode side is then impossible still. The invention utilizes a filament converter in the form of a coreless filament transformer (14, 15, 16, 17) and the primary coil (14, 16) of the filament transformer is arranged so as to be coaxial with the secondary coil (15, 17) of the filament transformer. Moreover, the two coils are arranged around a carrier (5, 10), which is preferably the high-voltage connection socket (10) or the tube neck (5). This is an inexpensive and structurally simple solution which enables integration of the filament converter in the protective tube housing (1) in conventional X-ray apparatus.
