摘要： An x-ray tube assembly (16) includes a housing (40) and an insert frame (52) supported within the housing (40), such that the insert frame (52) defines a substantially evacuated envelope in which cathode (56) and anode (54) assemblies operate to produce x-rays. An x-ray transmissive window assembly (70) extends between and in a fluid-tight relationship with the housing (40) and the insert frame (52). The window assembly (70) includes an insert window (72) brazed to the insert frame (52), a top plate (76), which is connected to and substantially surrounded by a flange (78), where the flange (78) is fastened to the x-ray tube housing (40). An annular side plate (86) is connected to a fluid-tight relationship with both the insert frame/window interface (74) and the flange (78). The window assembly (70) cools the window through enhanced heat transfer while preventing housing coolant from contacting the insert window (72), thereby eliminating coolant carbonization on the window (72) and enhancing x-ray beam quality.

摘要： An x-ray tube assembly (16) includes a housing (40) and an insert frame (54) supported within the housing (40), such that the insert frame (54) defines a substantially evacuated envelope in which a cathode assembly (60) and a rotating anode assembly (58) operate to produce x-rays. The rotating anode assembly (58) includes an anode target plate (64) coupled to a rotor (66) and bearing shaft (82), which is rotatably supported within a bearing housing (84), by a plurality of ball bearings (86). A heat barrier (90) substantially surrounds the bearing housing (84) and is coupled, along with the bearing housing (84) to an anode cold plate (100). The anode cold plate (100) includes a grooved cover (102), a basin (110), and a plurality of corrugated fins (120) disposed therein. Coupling both the bearing housing (84) and the heat barrier (90) to the anode cold plate (100) provides an effective means for cooling the bearing assembly (80).

摘要： An apparatus (20) for setting a filament (22) on an electrode (24) comprises a body (52) having a central member (54) with a longitudinal axis (A—A), a first end member (56) and a second end member (58). The first and second end members (56, 58) are located at opposite ends of the central member (54) and each extends away from the longitudinal axis (A—A) thereby forming a recess (59). Each end member (56, 58) includes a surface generally facing the recess (61, 63) and an outer surface (74, 76). A bore (68) in the body is adapted to receive a retaining member (not shown) for mounting the body (52) to the electrode (24). A cavity (70) extends through the first end member (56) from its outer surface (74) to its recess facing surface (61). A cavity (80) in the second end member (58) opens toward the recess (59). The cavities (70, 80) in the first end member (56) and second end member (58) are located opposite one another across the recess (59).

摘要： An anode (A) closes one end of an evacuated envelope (C) and a cathode end plate (22) closes the other. A cathode assembly (B) is mounted on a bearing (40) in the evacuated envelope such that the envelope and cathode can undergo relative rotation. A motor (38) rotates the anode and envelope while a pair of magnets (44, 46) hold the cathode assembly stationary. Bearing (40) functions as a current path from a current source (72) to the primary windings of a transformer (58). Another bearing (94) provides a return current path from the transformer to the current source. The secondary windings of the transformer are connected with a cathode filament (52). The transformer enables a relatively low ampere current to pass through the bearings to limit cathodic damage to the bearings, yet provides sufficient amperage to the filament to cause thermionic emission. The bearings provide a direct transfer of current which does not degrade the vacuum in the envelope in such a manner that the current through the cathode filament can be measured directly from outside the envelope.

摘要： An x-ray tube includes an anode (A) and envelope (C) which are rotated (D) at a relatively high rate of speed. A cathode assembly (B) is supported in the envelope on a bearing (32). In order to hold the cathode assembly stationary, a magnetic susceptor (40) having periodic projections (44) is disposed with the projections closely adjacent an outer peripheral wall (20) of the envelope. A plurality of permanent magnets (52) are mounted on a stationary keeper (50), each magnet adjacent one of the susceptor projections. Preferably, the magnets have alternating polarity such that magnetic flux lines (54) flow between adjacent magnets through the magnetic susceptor.

摘要： A cathode assembly (18, 216) for an x-ray tube (1) includes a base (60, 220) to which a filament (66) is mounted. A pair of deflectors (82, 84) are carried by the base for deflecting a beam (A) of electrons generated by the filament. Metal tubes (130, 132) are mounted in bores (106) of insulator blocks (104, 105). Metalized ends (150) of the insulator blocks are brazed into bores (122, 222, 224) in the base. A rod (130, 132) attached to the deflector is slid into the tube and the deflector's position and alignment are gauged and accurately set. The rod and tube are crimped to set the deflector position then welded.

摘要： An evacuated envelope (C) which is connected with an anode (A), has a cathode assembly (B) rotatably mounted inside. Magnets (44, 46) hold the cathode assembly stationary as the anode and envelope rotate. A ferrite core transformer (60) includes a ferrite core primary (66) stationarily mounted exterior to the envelope. A secondary (64) is mounted to the cathode assembly interior to the envelope. The secondary winding includes a ferrite core (70), a portion of which is surrounded by a ceramic, dielectric bobbin (76). The bobbin includes walls or ridges (78) which define a spiral groove (80) therearound in which an uninsulated electric wire (82) is received. The uninsulated electric wire is connected with a cathode filament (52). The primary winding has a ferrite core (90) that has about five times the cross section as the secondary ferrite core to compensate for a low, about 20%, coupling efficiency between the primary and secondary windings. Preferably, the primary winding core tapers (94) adjacent its pole faces to focus magnetic flux toward pole faces (72, 74) of the secondary ferrite core.

摘要： An X-ray tube having two individually energizable cathode filaments. If a primary filament is shorted to a cathode cup, a switch mounted inside the tube housing is thrown to couple a second filament to a filament energization signal. This avoids the necessity in replacing the X-ray tube if the primary filament is shorted and lengthens the effective life of the X-ray tube.
