Patent ID: 7519208

Claim:
In a computed tomography system having a radiation detector with a plurality of detector rows, said radiation detector supplying output signals, resulting from irradiation of a subject in the computed tomography system, to a data acquisition unit and said data acquisition unit generating digital data from the respective output signals, a method for error-tolerant data transfer between the data acquisition and an image reconstruction unit remote therefrom comprising the steps of: in said data acquisition unit, dividing said digital data into data packets each comprising multiple bits and transferring said data packets, as a data stream, from a transmission device, in communication with the data acquisition unit, to a reception device, in communication with the image reconstruction unit, and buffering said data packets in said reception device; in said data acquisition unit, formulating said data packets so that each packet comprises only data bits selected from the group consisting of data bits of a segment on one detector row and data bits of one complete detector row; in said reception device, detecting incomplete and/or missing data packets in said data stream; for each data packet detected as incomplete, storing the incomplete data packet in a storage region at the reception device and marking that storage region as a marked storage region; for each data packet detected as missing, marking a storage region at the reception device therefor, as a marked storage region; and for each of said marked storage regions, interpolating data in said reception device to complete an incomplete data packet or to replace a missing data packet, from data selected from the group consisting of data from adjacent segments of the same detector row if said data packets comprise said data bits of a segment of one detector row, and data from an adjacent detector row if said data packets comprise said data bits of one complete detector row.
