CT scanning system and a method for receiving and transmitting raw data therein

摘要

A method of transmitting raw data by a data acquisition system in a CT scanning system, wherein the CT scanning system comprises a rotational part of a gantry with at least one raw data backup memory, and wherein the data acquisition system is configured to adopt the at least one backup memory for storing a backup of the raw data. The method comprising: generating the raw data as scanned; storing generated raw data in the at least one backup memory; transmitting the raw data to an operation console in the CT scanning system; and repeating generating, storing, and transmitting of the raw data in the case of an unfinished scan, until the unfinished scan is finished.

1. A method of transmitting raw data by a data acquisition system in a CT scanning system, wherein the CT scanning system comprises a rotational part of a gantry with at least one raw data backup memory, and wherein the data acquisition system is configured to adopt the at least one backup memory for storing a backup of the raw data, the method comprising:
generating the raw data as scanned; storing the generated raw data in the at least one backup memory; transmitting the raw data to an operation console in the CT scanning system until the scan is finished, determining whether an error in transmitting of the raw data has occurred, obtaining at least one identifier in the instruction associated with said error; reading from the at least one backup memory, the backup raw data corresponding to the at least one identifier; and transmitting the read raw data to the operation console.
