Patent Number Title Of Patent Date Issued
7209544 X-ray tube cathode assembly and interface reaction joining process April 24, 2007
An x-ray tube cathode assembly (28) includes a support arm (36) comprising a first metal. A ceramic insulator (70, 82) has a first metalized surface (72, 86) wherein the metalized surfaces comprise a desired amount of the first metal. A first member of filler material (90) is in contact
6480572 Dual filament, electrostatically controlled focal spot for x-ray tubes November 12, 2002
A dual filament x-ray tube assembly (16) includes an evacuated envelope (52) having an anode (54) disposed at a first end of the evacuated envelope (52) and a cathode assembly (62) disposed at a second end of the evacuated envelope (52). The cathode assembly includes a variable-length
5581591 Focal spot motion control for rotating housing and anode/stationary cathode X-ray tubes December 3, 1996
An x-ray tube includes an anode (A) and an envelope (C). A cathode assembly (B) which is supported in the envelope on a bearing (32) emits a beam of electrons which strike the anode forming a focal spot. The anode rotates (D) relative to the cathode such that focal spot follows a general
