摘要： A CT device for imaging slices that are inclined toward the system axis has an input unit for the entering the position of at least one slice that is to be imaged and that is inclined toward the system axis. A volume which completely contains the slice that is to be imaged and that is inclined toward the system axis is scanned by initially generating planar tomograms from the data acquired during the scanning of the volume, and the tomogram of a desired slice that is inclined toward the system axis is produced from these planar tomograms by multi-planar reconstruction.

摘要： An arrangement for the dynamic direct display of pulses in the nanosecond range operates without oscilloscopes or other special display apparatus. To display pulse timing or amplitude characteristics, a pulse sequence is applied to an equidistant tapped delay line, the output from each tap being connected to a bistable storage element with an indicator lamp in the output. A plurality of indicator lamps are arranged in the form of a matrix. If a pulse occurs on a tap during a sampling interval, the associated indicator lamp is turned on. The sequence and identity of the turned on indicators is indicative of the pulse spacing and the pulse width in the pulse sequence.

摘要： The invention relates to dealing with problems affecting a medical apparatus. In this method, if a problem occurs, a service center is notified of the problem by telecommunication, whereupon the service center issues problem-specific instructions by telecommunication for determining data with respect to the notified problem. Then, on the basis of the determined data, of which it has been notified by telecommunication, the service center determines a measure for dealing with the problem and gives notice of it by telecommunication, whereupon the measure for dealing with the problem is taken and a test of the medical apparatus is performed.

摘要： A computer tomography apparatus has a radiation detector formed by a row of detector elements, and a data acquisition system having a detector channel for each detector element. A multiplexer samples the signals of the detector elements. To avoid image artifacts due to differing disturbing influences in the transmission and conversion of the measured values for the individual detector channels, the multiplexer has a number of levels, and is controlled so that sampling of the individual detector channels takes place in changing sequences. A bank of analog-to-digital converters follows the multiplexer, and the allocation of the converters in the bank to groups of detector channels is also changed during data acquisition. The output signals of the analog-to-digital converters, which represent individual outputs for each channel, are entered into a memory in proper numerical sequence.
