摘要： In a CT system and a method for error-tolerant data transfer between a data acquisition unit and an image reconstruction unit therein, digital data are divided into data packets and are transferred as a data stream from a transmission device to a reception device and are buffered in the reception device for further processing. The data packets are selected such that they respectively contain the data of a segment of a detector row or of a complete detector row of the CT system. Incomplete and/or missing focal paths are detected in the reception device and a storage region is reserved and marked as incorrect for these data packets. The incorrect and/or missing data packets are later interpolated from the data of adjacent detector rows and/or adjacent segments of a detector row and/or successive projections precede or follow the incorrect and/or missing data packets. Missing data packets due to transfer interferences can also be tolerated.

摘要： A device for non-contacting transmission of electrical signals between one part moving relative to another part has at least one strip conductor pair for symmetrical signal transmission attached on a first of the two parts, in which strip conductor pair the electrical signals are supplied from a transmission module for differential signal transmission. At least one reception element is attached on the other of the two parts, at a slight separation along at least one segment of the strip conductor pair, and is connected with a reception module. The strip conductor pair is provided with one or more components for reduction of a common mode signal component that arises therein due to the differential signals therein. Additionally or alternatively, compensation elements for adaptation of a time offset between signals on the output conductors are arranged in the output conductors of the transmission module that minimizes the common mode signal component. A reduced electromagnetic perturbing radiation is achieved with the device during the non-contacting signal transmission by capacitive RF coupling.

摘要： A method is disclosed for producing tomographic pictures with the aid of an X-ray CT system including at least two X-ray sources arranged on a gantry with an angular offset to scan an examination object. In at least one embodiment of the method, in order to determine the scattered radiation distribution, pre-scanning is carried out in which the X-ray sources rotate about the examination object and the dose rate is modulated as a function of the rotation angle, no radiation dose is output over the majority of the revolution, at specific pre-scan angles a dose rate is produced briefly and individually in each case by the X-ray sources of the focus/detector systems, and the received scattered radiation is measured simultaneously by the detectors of the at least one other focus/detector system. Moreover, at least one embodiment of the invention also relates to an X-ray CT system having at least two focus/detector systems and an arithmetic and control unit with a memory for program code that carries out during operation the method steps being stored.

摘要： In a device and a method for data transfer between two parts moving relative to one another while maintaining a slight distance between the parts, a transmission device with at least one transmission antenna (connected with a transmitter) and a reception device with a reception antenna (connected with a receiver are used). The transmission antenna and/or the reception antenna is/are fashioned as radio-frequency conductors and are arranged such that signals fed into the transmission antenna during at least one segment of the relative movement are received by the reception antenna by capacitive or inductive coupling. One or more compensation devices is/are arranged between the transmitter and the receiver. The compensation devices counteract signal distortion caused on the radio-frequency conductor by propagation of the signals. Higher data transfer rates can be realized in a cost-effective manner given the use of radio-frequency strip conductors as transmission and/or reception antennas.
