    摘要: To reproducibly position a patient in an imaging device, with regard to the coordinate system thereof, so that such a reproducible positioning of the same patient is additionally possible in another imaging device, so that the images generated with both modalities can be congruently overlaid for an image fusion, a body shell is adapted to the patient, the shell supporting the patient for positioning on the patient table. By shaping of the shell contour to conform to the shape of the contour of the table, the position of the shell on the table is defined. Both imaging devices are equipped with a table of the same shape. The desired adaptation of the respective geometries of the image generation systems is achieved by using shell as a test body, equipped with suitable landmarks that are delectable in the images of both modalities.

    摘要: An x-ray diagnostics installation has a solid-state image transducer with a layer whose electrical resistance is dependent on the intensity of incident radiation from an x-ray source, and an electro-luminescent layer in contact therewith which converts the resistance into a corresponding brightness value. Due to the decay time of the electro-luminescent layer, an image will be temporarily stored in the solid-state image transducer after the x-ray source has been deactivated. This temporarily stored image is read-out, after deactivation of the x-ray source, by a scanner for converting the brightness of the picture elements of the electro-luminescent layer into corresponding electrical signals. These signals are supplied to a data acquisition and processing system, which generates an image for display.

    摘要: The organ-related keys for selecting radiographic exposure parameters according to a predetermined programming may include special correction keys to be actuated according to an estimate of patient transparency, or in any event the keys representing respective organs imply a range of expected attenuations of the incident radiation due to the presence of the patient. The disclosed system senses the implied patient transparency range from the setting of the control keys, and compares the same with an actual value signal due to the specific patient and takes suitable control action in the event that patient bulk does not fall within the predetermined range. For example, the control action may comprise a shut off of the radiation source, or a change of X-ray tube high voltage setting or of anode current. It is also possible for the system to automatically store data on the parameters selected such as the geometry of the camera and/or the X-ray film in service, and to utilize such data to improve the accuracy of the transparency actual value signal, or to aid in determining the response to be made by the system to detected discrepancies.

    摘要: A radiography apparatus with which x-ray shadowgraphs are produced has a detector array in the form of a line or strip, and an x-ray radiator which is moved in a direction perpendicular to the line direction of the detector array for scanning a measuring field from different directions. The detector array accordingly receives x-radiation proceeding through the measuring field from different directions. A screen or slotted diaphragm having diaphragm shafts directed onto the detector array is disposed between the x-ray radiator and the measuring field, and blanks out x-radiation which is not useful for generating the shadowgraph image.

    摘要: A medical installation for examining a patient irradiates at least a portion of the patient with an examination field, and detects the attenuated field and generates an image therefrom. During exposure of the patient to the examination field, a contrast agent injector is operated to intermittently inject contrast agent into the patient at a selected frequency. The image is generated of the patient at an image pick-up frequency, and the frequency of injection of the contrast agent may be matched to, or differ from, the image pick-up frequency. The liquid injected into the patient will have alternating sections with and without contrast agent following in succession.

    摘要: An x-ray diagnostics installation for subtraction angiography has an image memory connected to an output of an x-ray image intensifier video chain which has a number of addresses for storing individual x-ray video signals obtained during a dynamic body cycle of a patient under observation. A differencing unit receives stored signals from the image memory as well as current video signals and substracts those signals to form a superimposed image. Entry and readout of signals to and from the image memory is under the command of a control unit which is connected to the patient through, for example, an EKG circuit for identifying selected occurrences in the body cycle under observation. Entry and readout of data from the image memory is thereby controlled in synchronization with the selected occurrences in the cycle.

    摘要: In an exemplary embodiment, a radiation measuring arrangement has two x-ray tubes of different radiation energy which generate radiation beams penetrating the radiography subject, and also has a radiation receiver which determines the radiation intensity behind the subject. The radiography subject is irradiated from different directions. A computer determines, for every image point, the attenuation coefficient for every radiation energy and determines therefrom the mean ordinal number and the density. The radiation receiver is designed as a stationary detector ring. For scanning only the x-ray tubes are rotated about the radiography subject. They are maintained at such a distance from one another that no detector element is simultaneously impinged upon by both radiation beams.

    摘要: In an exemplary embodiment, the measuring arrangement including the x-ray tube and radiation receiver, is capable of being locked against rotation, and the patient support is capable of being locked against longitudinal movement. The x-ray beam is selectively limited in extent by means of an adjustable diaphragm. In the case of a locked measuring arrangement and patient support and a limited x-ray beam, the measured values of the radiation receiver are detected by a computer which, from them and from information regarding the cross section of a vessel to be examined, determines the concentration and/or quantity of an x-ray contrast agent therein. The information regarding the cross section is obtained with a normal computer tomographic scanning operation.
