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.

摘要： An X-ray diagnostic installation for producing a transverse layer or planigraphic image including a first X-ray measuring arrangement having X-ray source which generates an X-ray beam whose extent of cross-sectional diffusion perpendicular to the layer is equal to the layer thickness, and equal to or less than the layer thickness in parallel to the layer, and a radiation receiver which measures the radiation intensity behind the object at successive equidistantly located points, as well as a drive arrangement for the measuring arrangement adapted to generate a linearly guided scanning motion extending in perpendicular to the direction of the central beam across the total expanse of the object, in an alternating sequence with a rotational motion about small equidistant angles, whose sum comprises 180.degree., and about a center of revolution lying approximately in the central portion of the layer surface on the main radiation beam. In addition to the first measuring arrangement, a second measuring arrangement is provided which is parallel offset with respect to the former in the direction of the linear movement, whose X-ray source generates radiation having a different value of radiation energy in comparison with that of the first X-ray source; and including a calculator which determines for each image point from the measuring signals of both measuring arrangements for the two different values the radiation energy, the two adsorption coefficients or their proportional magnitudes, forms their respective quotients and from the foregoing, by means of a computed-in calibrating table provides the median ordinate value or a corresponding magnitude for each image point.

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 registration aid for medical images obtained from an examination subject respectively with different imaging modalities at separated points in time, has a carrier adapted to be reproducibly applied to an examination subject at separated points in time at a substantially identical position on the examination subject at each of the separated points in time, and at least one landmark provider carried by the carrier, the landmark provider providing a first landmark visible in a first of the imaging modalities and a second landmark, different from the first landmark, visible in a second of the imaging modalities. The landmark provider provides the first and second landmarks with a fixed spatial relation relative to each other to allow contents of an image obtained with the first of the imaging modalities to be brought into registration with contents of an image obtained with the second of the imaging modalities, with the carrier being applied to the examination subject while each of the images is obtained.

摘要： A system for infusing medicine into the body of a patient includes an implantable infusion apparatus containing a dosing unit with a reservoir for the medicine and a medicine delivery pump for pumping doses of the medicine from the reservoir into the patient. The infusion apparatus also includes a sensor for sensing a parameter of the patient for controlling the dosing of medicine according to the sensed parameter. The dosing unit and the sensor are galvanically separable and are each provided with separate telemetry communication units for communication with an external programmer/controller. The external programmer/controller includes telemetry communication units for selectable communication with the dosing unit or the sensor or both simultaneously. The telemetry communication units of the external programmer/controller, the dosing unit and the sensor are constructed for bi-directional communication between the external controller and each one of the dosing unit and the sensor.

There is provided a perforated diaphragm of radiation-absorbing material near the tube, which diaphragm can be introduced into the ray path selectively. Two image memories for an X-ray picture with a diaphragm and an X-ray picture without a diaphragm and an image processing system serve for comparing the image information of the two X-ray pictures to determine and eliminate the stray radiation component.
