Abstract: There is disclosed an assembly for slit radiography with image equalization, comprising a two-dimensional dosimeter for detecting the amount of X-rays transmitted through a body. During a scan different parts of the dosimeter detect the transmitted X-rays. Thereto a system of essentially parallel electrodes is present. The parallel electrodes extend in the direction of scanning and are connected to a control device for forming control signals for the adsorption device.

Abstract: There is disclosed an assembly for slit radiography with image equalization, comprising an X-ray source which can scan a body for examination via a slit of a slit diaphragm with a flat, fan-shaped X-ray beam over a scanning path in a direction transverse to the lengthwise direction of the slit for forming an X-ray shadowgraph on an X-ray detector; an absorption device which under the control of control signals can influence the fan-shaped X-ray beam per sector thereof, in order to permit control of the X-ray radiation falling in each sector on the body to be examined; and detection assembly which is designed to detect the quantity of X-ray radiation transmitted by the body instantaneously per sector during a scanning movement of the X-ray beam and to convert it into corresponding signals.

Abstract: An image pickup device comprises a matrix of rows and columns of image pickup elements. Image information is transferred in the column direction in the time-delay-and-integration mode. Two shift registers are associated with each column of image pickup elements. During a first period information from the image pickup elements of each column is transferred to a first one of each two shift registers associated with each column and during a second period information is transferred to the second one of each two shift registers associated with each column.Such an image pickup device can be used in radiography as a means for detecting x-ray radiation transmitted by a body under examination. In order to obtain a dual energy image a first or a second spectral center point is periodically imparted to the x-ray radiation synchronously with the first and second periods.

Abstract: Image pickup device comprising a matrix having horizontal rows and vertical columns of image pickup elements and having means supplying clock signals to the matrix of pickup elements in order to shift image information in the column direction in the time delay and integration mode. Along each column in image pickup elements at predetermined positions a determination is made of whether the charge at those positions exceeds a limit value. If so, the charge in such image pickup elements is removed completely and integration starts again. From the charge in the last element in a column as well as the number of times charge has been removed it can be deduced what the total charge would have been without removal.Thus images can be recorded the contrast ratio of which otherwise would exceed the maximum contrast ratio which the image pickup device is capable of recording.

Abstract: A system comprising an X-ray source (1), an elongate detector tube (3) including at least one cathode (5) extending in the longitudinal direction of the tube and at least one anode (6) located opposite to the cathode, a slit diaphragm (2), and a filter (4) mounted in the path between the X-ray source (1) and the detector tube (3). The filter (4) blocks relatively low energy X-radiation in a portion of the beam emitted by the source (1). The cathode (5) is provided with an X-ray detection layer consisting of two strips (8',8") extending in the longitudinal direction of the tube (3). One strip (8") receives the radiation passed by the filter (4) and the other strip (8') receives the unfiltered radiation. The one strip (8") is of considerably greater thickness than the other strip (8').

Abstract: Apparatus for the non-contact disintegration of concrements present in a body by means of sound shockwaves generated in one focus of at least one liquid-filled reflector formed in a reflector block wherein the reflector exhibits rotary symmetry in the form of a semi-ellipsoid (or in the focal line of a toroidal reflector having a semi-elliptical cross-section configuration) and wherein the reflector focuses the sound shockwaves to a second focus and wherein the apparatus further comprises a liquid-filled coupling member connected to the reflector block in a liquid-tight manner. The liquid-filled coupling member is relatively movable to the reflector and can be placed in contact with the skin of the body.

Abstract: An image intensifier of the proximity-focus type, comprising at least one photocathode and at least one anode screen located opposite to the photocathode, said photocathode and said anode screen being disposed in a hollow body in which a vacuum prevails, while, in use, there is an electrical field between cathode and anode. According to the invention the photocathode surface and the anode screen surface extend substantially parallel to the axis of the hollow body.

Abstract: An apparatus for tomography, comprising an X-ray or gamma-ray source, at least one detector, and an image reconstruction apparatus. The detector is a spatially two-dimensional, continuous detector large enough to form a complete picture of the projection of the object section thereon, taking into consideration the place of the object section and of the source of radiation relative to the detector. The detector is connected by optical or fibre-optical means to a luminance intensifier tube. This tube may be coupled, either optically or fibre-optically, to a television pick-up tube whose output is coupled to the image reconstruction apparatus. In one form of the invention the detector is an X-ray screen, which is preferably concave towards the source of radiation.

Abstract: An image intensifier tube of the proximity focus type has a transparent cathode window with a curved inner surface and an anode window formed by a fiber optics plate having an inner surface curved to be substantially complementary to the cathode window inner surface. The arrangement mitigates the so-called "chicken-wire" effect and other flaws inherent in intensifiers using fiber optics at both the cathode and the anode ends. It is cheaper in manufacture and may be made of smaller depth, thereby simplifying its incorporation in existing apparatus.

Abstract: The radiation spectrum from a scene is split according to two wavelength regions to provide two spaced images of the same scene, each from the radiation of a different one of said regions, on the cathode of an image intensifier tube. The images are intensified by means of a desired number of image intensifier tubes and the images thus produced on the anode of the last tube are recombined each in an added different color.
