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 medical system such as a diagnostic or a therapeutic system includes a fixed base unit with a control unit and a mobile assembly mounted rotatably on the fixed base unit. The fixed base unit and the mobile assembly are set up to exchange data. Transmission of first control data from the control unit to the mobile assembly takes place via a first transmission path. Transmission of second control data to the control unit and transmission of measured data from the mobile assembly takes place via a second transmission path.
