摘要： An X-ray source has an emitter for the production of an electron beam and an anode on which the electron beam strikes in an X-ray focal spot, and a magnet system that produces a dipole field and a quadrupole field that is superimposed on this dipole field, for deflecting and focusing the electron beam onto the anode. In addition, an arrangement is provided that operates together with the magnet system for the adjustment of the size of the X-ray focal spot. This arrangement, in order to set a desired size of the X-ray focal spot, adjusts the quadrupole field in so that the X-ray focal spot has a width corresponding to the desired size of the X-ray focal spot, and supplies to the magnet system a wobble signal that influences the dipole field, this wobble signal effecting a periodic displacement of the electron beam in a direction transverse to the extension of the width of the X-ray focal spot. This gives the focal spot an effect length, resulting from the deflection and measured in the direction of the deflection, to achieve a particular ratio of the effective length to the width of the X-ray focal spot.

摘要： X-ray examination installation, particularly for computed tomography for mammography, has a rotating bulb x-ray tube with a cathode-side drive as its x-ray source, with the tube being oriented so that its anode faces toward the exposure side or actuation side of the system. The distance between the x-ray beam exit window of the tube, and the exposure side or actuation side of the system, thus is made small.

摘要： In an X-ray diagnostic apparatus, for acquiring the cross-section, position and/or alignment, relative to a target, of an electron beam generated by an electron generating system, at least one conductor is provided in the region of the target so that a signal can be derived by the conductor under the influence of the electron beam and supplied to an evaluation stage. The conductor is composed of a material having an atomic number lower than that of tungsten, so that no undesirable radiation arises due to the interaction of the electrons with this conductor.

摘要： An x-ray tube has an annular vacuum housing through which an electron beam passes in an annular path, an annular target from which x-radiation emanates during operation of the x-ray tube when the electron beam strikes it at a point of incidence, and a beam deflector which is movable along the circumference of the vacuum housing and which deflects the electron beam such that it is incident onto the target at a point of incidence that is dependent on the position of the deflector along the circumference of the vacuum housing. An x-ray beam emanating from the target is thus caused to move around the interior of the vacuum housing in the manner necessary for producing computed tomograms of a subject disposed in the interior of the vacuum housing.

摘要： In an electronic x-ray computed tomography apparatus that enables a scanning of approximately 360.degree., the electron beam is guided in an annularly fashioned magnet arrangement that has a U-shaped cross section. The U enables the guidance of the electron beam to the annular anode and enables the emergence of the x-radiation. The magnet arrangement is composed of a number of side-by-side U-shaped magnet elements arranged to form an annulus with a coil for excitation of the magnet element respectively arranged on the cross bar of each U. A single magnetic arrangement is thus used to generate both the electron beam guidance field and, by means of a sudden polarity reversal of a magnet element disposed at a desired deflection location, the deflection field.
