摘要： The invention relates to an X-ray device, notable a device for X-ray fluoroscopy, which includes an X-ray source and an X-ray detector for the continuous formation of X-ray images of a patient (5) from an invariable position of the X-ray source (2) and the X-ray detector (3). The invention includes indicator means for illuminating and/or monitoring essentially the radiation zone over the patient which is traversed by X-rays. This offers the advantage that for the physician it quasi visualizes or monitors the radiation zone which is traversed by X-rays during a treatment with simultaneous formation of X-ray images so that the physician can make sure that he or she, notably his or her hands, is not inadvertently exposed to a continuous X-ray dose.

摘要： The invention relates to an image processing method for improving the signal-to-noise ratio for a series of MR images or CT images which are based on the projection-reconstruction method. First the pixels which reproduce the same sub-structure in the projection images are determined in the one-dimensional projection images constituting the two-dimensional MR or CT images. The image values of these pixels are subjected to noise filtering. Two-dimensional MR images or CT images are reconstructed from the noise filtered one-dimensional projection images.

摘要： A MR method determines nuclear magnetic resonance distribution in an examination area and the position of at least one microcoil which is located in the examination area in or on an examination object. In the presence of a homogeneous stationary magnetic field acting on the examination area, sequences are carried out in which at least one high-frequency pulse acting on the examination area is generated, and after the high-frequency pulse an MR signal induced in the microcoil is detected under the influence of a gradient magnetic field that acts on the examination area. Then the position of the microcoil in the gradient direction defined by the gradient field is derived from the detected MR signal. The aforementioned sequences are repeated for another gradient direction, and MR signals are detected by a further receiving coil arrangement to determine the nuclear distribution. Without additional measuring sequences, a position is detected in a manner that the sequences are continuously repeated while the gradient direction is varied, and that the position of the microcoil and the nuclear magnetic distribution are derived from MR signals detected simultaneously by the microcoil and the receiving coil arrangement.

摘要： The invention relates to a method of forming a series of MR images in which, in the presence of a steady magnetic field, sequences comprising at least an RF pulse and a magnetic gradient field which is varied from one sequence to another are continuously applied to the examination zone, from the image signals thus generated there being reconstructed MR images, the oldest MR signals used for the reconstruction of an MR image being replaced upon reconstruction of the next MR image by the respective newly generated MR signals. Low-artefact reproduction of dynamic processes in the examination zone can be achieved by varying the direction of the magnetic gradient field active during the generation of an MR signal from one sequence to another so that the range of the magnetic gradient field directions required for the reconstruction is distributed between the respective newly generated MR signals. The invention also relates to a device for carrying out this method.
