Method and apparatus for error-tolerant data transfer for a CT system |
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.
