    摘要： Method and apparatus for making a tomogram according to this invention include one elongated support member supporting an X-ray tube and a film device in an opposed relation with each other at both ends thereof and one vertical shaft supporting the elongated support member thereon. Movement of the axis of the shaft along a desired curve results in the movement of an X-ray beam in the state of the X-ray beam intersecting the curve. In the meantime, an angle of rotation around the axis of the shaft is adjusted so as to maintain an angle of intersection of the X-ray beam with the curve at a predetermined angle. A film surface is moved relatively with respect to the X-ray beam so as to allow the beam to scan the film surface. The velocity of movement of the film surface is synchronized with the movement of the shaft. In the invention, the aforementioned movement of the shaft along the curve, the aforementioned angle of rotation of the shaft and the aforementioned movement of the film surface are respectively controlled or adjusted by digital signals.

    摘要： An installation for producing radiological angiographic exposures, consisting of a particularly longitudinally displaceable patient support, at least one exposure apparatus, as well as setting means for adjusting the exposure apparatus prior to commencing a series of exposures, and a program control arrangement including program cards for the control of the installation in conformance with a currently desired dynamic exposure program during the period of a series of exposures. Each program card further includes an additional region for the recording of the static exposure program, which determines the setting of the installation preceding commencement of the exposure, and wherein the program control arrangement, moreover, is constructed for effecting the sorting of the static exposure program and the corresponding setting up of the installation.

    摘要： An X-ray diagnostic installation having a patient support arrangement, an X-ray tube for transilluminating a patient, a high-voltage generator for the X-ray tube, a control installation for the high-voltage generator and for a heating filament voltage generator, a plurality of exposure systems for X-ray images which are selectively employable in conjunction with the X-ray tube, and an organ selecting arrangement for the organ-programmed setting of the exposure values for each exposure system, which possesses a switch position for each organ whose exposure volume is programmed, in which switch means for the exposure values associated with the particular switch position is actuated for the setting of the programmed exposure value. The X-ray diagnostic installation has a single organ selector which is common to all exposure systems, and that there is provided a selector arrangement by means of which the switch means associated with the one switch position of the organ selector is connectable to the setting means for the exposure values corresponding to the exposure program for the currently selected exposure system and the organ which is associated with the switch position.
