摘要： In an exemplary embodiment, a radiation detector for reception of the radiation emerging from the radiography subject delivers electric output signals corresponding to the received radiation profile, a scanner device rotates the radiographic unit about an axis which passes through the focus of the x-ray tube and approximately through the detector center, and a measured value processing and display unit determines and reproduces the x-ray shadow image corresponding to the scanning movement of the radiographic unit (1, 4). The processing and display unit is designed in the manner of a radar display apparatus in which a number of concentric image point circles are recorded, each of which, (for the case of a radiation detector consisting of a series of individual detectors), is locally associated with a specific individual detector and is modulated in its intensity corresponding to the output signals of the associated individual detector.

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 method and apparatus are disclosed for generating a high current, high-voltage pulse suitable for driving a shock wave source of the type which generates a shock wave in an acoustic transmission medium. In the apparatus, a signal generator generates a low-voltage signal having an energy content sufficient for generating the shock wave, and a pulse-shaping network, connected between the signal generator and the shock wave source, as a transfer function which shortens the signal duration of the low voltage signal from the signal generator so that the low-voltage signal is converted into a high voltage pulse suitable for driving the shock wave source. The high-voltage pulse has an energy content substantially the same as that of the low-voltage signal.

摘要： The exemplary embodiments produce successive x-ray beams with different wavelengths and may comprise a rotating anode whose anode body has x-ray generating parts of different materials. Heretofore, the x-rays arising at the parts have been conducted through filters outside the tube which, synchronously moved, are allocated to the parts of the rotating anode. Since, however, the allocation of the filters to the parts of the anode is difficult in such a subsequent synchronization, according to the disclosure a fixed allocation ensues in that the filters are incorporated into the tube and are integrated in the rotation of the anode. To that end, they are designed as walls lying at right angles in the discharge path of the x-rays and are rigidly connected to the shaft of the anode arrangement. Such x-ray tubes are particularly suitable as a radiation source for employment in medical x-ray diagnostics.

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.
