摘要： The filament for the emission of the electrons in an X-ray tube inevitably evaporates gradually during operation of the tube. Depending on the location of the filament in the tube, the metal vapor thus released is deposited on the X-ray window of the tube. Consequently, the transmission of the X-ray tube window gradually decreases in the course of the service life of the tube. In order to counteract the deposition of filament material, an edge structure is provided on the inner side of the window; this structure comprises edges which extend perpendicularly to the window surface, and is preferably a honeycomb structure with hexagonal cells. The height of the edges is chosen so that, viewed from the filament, the edge structure forms a shadow zone for the entire X-ray window, so that the metal vapor is deposited on the structure instead of on the window.

摘要： An anode (16), (16') and a cathode (14), (14') are mounted in an evacuated envelope (12), (12') of an x-ray tube (10). One of the anode and cathode is rotatably mounted on bearings (20), (20') relative to the evacuated envelope. In the embodiment in which the anode is rotatably mounted relative to the evacuated housing, a rolling ring assembly (40) provides a current path from the anode through the evacuated housing to ground without the current path passing through the bearing (20). In this manner, pitting and other damage to the bearing due to arcing is eliminated. In the embodiment in which the cathode is rotatably mounted relative to the evacuated envelope, the anode and envelope rotate as the cathode is held stationary (58, 60). A plurality of rolling ring assemblies (40'.sub.1, 40'.sub.2, . . . ) provide electrical communication between electrical control circuitry disposed outside the rotating housing and the cathode assembly (14'). The electrical communication includes providing current to filaments of cathodes (30'.sub.1, 30'.sub.2) of the cathode assembly.

摘要： A toroidal x-ray tube (I) is supported and selectively positioned by a gantry (II). The x-ray tube includes a toroidal housing (A) in which a rotor (20) is rotatably mounted. One or more cathodes (C) are mounted on the rotor for generating an electron beam which strikes an anode (B) to generate a beam of x-rays which pass through a patient aperture (62) to strike a detector (60). The x-ray tube includes pre-collimators (70, 74) having slots (72, 76) for passage of the x-ray subsequent to generation thereof and prior to being collimated by the collimator (90). A ring collimator (90) collimates an x-rays formed into a fan shaped beam. The collimator (90) includes a first ring (92) and a second ring (94) which are concentric. The distance between the first and second rings (92, 94) is adjustable to adjust the slice thickness of the final image. The x-ray tube provides improved final images in that reduction of off-focal radiation occurs due to the utilization of pre-collimators and the collimation of x-rays is flexible due to adjustability of slice thickness.

摘要： Apparatus for the production of short-wave electromagnetic radiaion, especially in the x-ray and gamma-ray region, by means of the interaction between accelerated charged particles, especially electrons or positrons, and a crystal lattice, with a charged-particle source for the production of a beam of energetic charged particles and with a crystal arrangement which is so arranged in the path of the charged particle radiation beam that the charged particles traverse the crystal lattice of the crystal arrangement parallel to a predetermined lattice direction ("channeling-condition"). In order to produce an electromagnetic radiation beam with predetermined convergence or divergence, there are used a correspondingly convergent or divergent charged particle radiation beam (212) as well as a crystal arrangement (214) which is so bent that the channeling condition is at least approximately fulfilled for all charged particle paths in the crystal.
