摘要： In a method for positioning a catheter that has been inserted into a vessel and a device for implementing the method, the road map technique is used, wherein as a mask image, a three-dimensional mask image of the vessel which is composed of number of individual mask images is employed. From these individual mask images, that individual mask image is selected whose exposure direction corresponds optimally to the exposure direction of an instantaneously captured individual image, in order to combine this selected individual mask image with the instantaneously captured mask image and to display the resulting combined image.

摘要： An x-ray diagnostic system, particularly for cardioangiography, has an x-ray and an x-ray image intensifier/video chain or other x-ray image converters, with the x-ray and the x-ray image intensifier being cyclically moved during the production of a number of successive images. The motion of the vessel due to the heartbeat is compensated with a cardiac motion compensation unit in a small image region having an abnormality to be investigated, particularly a stenosis.

摘要： A patient support device which can be connected to patient placement devices of medical examination or treatment equipment, for example an MRI device, an X-ray machine, or of ambulances. The patient support device supports a patient during medical examination and treatment. The patient support device has a structural rigidity that is less than a minimal rigidity that enables the patient support device to be self-supporting while the patient is resting thereon. Such a patient support device can be designed in a simple manner in such a way that it can be used in MRI devices, as well as in devices of other types, and can be transferred between the devices without repositioning of the patient on different support devices.

摘要： In an exemplary embodiment, a bridge rectifier is coupled with the primary circuit of the high voltage transformer. In the d.c. current branch of the bridge rectifier, a smoothing capacitor and a thyristor are arranged. The thyristor is turned on and off with a pulse duty cycle which determines the capacitor voltage and hence the x-ray tube voltage. At the thyristor, an LC-oscillatory circuit is connected whose capacitance when the thyristor is conductive, is discharged via the latter and which effects the extinction of the thyristor via a free-running diode which is conductive in return oscillation phase and which is disposed parallel to the thyristor. In this manner, a high switching frequency of the thyristor and hence a minimal ripple of the x-ray tube voltage can be achieved.

摘要： An multi-planar radiation emission system, preferably an X-ray biplanar transillumination system, for generating planar images of a subject from different perspectives includes a first X-ray source which emits first pulses of X-ray radiation toward a subject from a first direction at a first repetition rate, a first imaging device which detects the first pulses and generates a first image of the subject from a first perspective, a second X-ray source which emits second pulses of X-ray radiation toward the subject from a second direction at a second repetition rate which is different from the first repetition rate, wherein the first and second pulses are temporally interleaved and non-overlapping, and a second imaging device which detects the second pulses and generates a second image of the subject from a second perspective. The first and second images are preferably planar images which are "moving" images in the sense that information from successive pulses is used to periodically update the planar images on a display. The relative reduction of the pulse repetition rate of the pulses used to generate one of the two planar images advantageously reduces potentially harmful X-ray emissions and reduces the image processing required to generate the planar images without significantly sacrificing useful information, since one of the two images is generally referred to only occasionally to provide the observer with a three-dimensional perspective of the planar image of greater interest.

摘要： An X-ray diagnostic apparatus has a device for controlling an X-ray source with regard to the emission of an X-ray beam and a filter positioner for the introduction or removal of at least one radiation filter into or out of the beam of radiation. A monitoring device checks whether there exists a positive difference signal between an output of a dosage power regulator and a kV controller. Given the presence of a positive difference, the monitoring device controls the filter positioner with regard to the removal of the radiation filter from the beam of radiation.

摘要： In an exemplary embodiment, a rectifier bridge is inserted in the primary circuit of the high voltage transformer and has an electronic circuit for adjusting the primary current to adjust the amplitude of the x-ray tube voltage pulse waveform. The comparator of the control loop cooperates with a storage circuit which is connected to a release circuit which releases it by means of a release pulse in a short time interval within a half wave of the x-ray tube voltage waveform for storing an instantaneous value of the error until the next release pulse. The storage circuit drives the electronic voltage adjusting circuit to adjust the pulse amplitude without distorting its waveform.
