[0051] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0052] In a multi-source CT system or a dual-source CT system, the amount of data generated is larger than that of a single-source CT system. The larger amount of data means that multiple slip ring antennas are needed to transmit the data generated by different detectors. The fixed transmission method between different slip ring antennas and different detectors has the problem of low transmission efficiency in some scenarios. For example, only one detector generates data, and these data are only transmitted through a fixed slip ring antenna, while the other slip ring antennas are idle. This method has low transmission efficiency. Or, for example, if a slip ring antenna fails, the data transmission link corresponding to the antenna will not be able to support scanning. To solve the above problems, the present application proposes a data transmission method, device, computer equipment and storage medium for a CT system.

[0053] The data transmission method of the CT system provided in the embodiment of the present application can be applied in the application environment as shown in FIG1. ​​The application environment includes a CT system, the CT system includes multiple data transmission links, each data transmission link includes a one-to-one corresponding detector 11, a data collection board 12 and a slip ring antenna 13; as shown in FIG1, data transmission link A includes detector A, data collection board A and slip ring antenna A, and data transmission link B includes detector B, data collection board B and slip ring antenna B. The communication connection between data collection board A and data collection board B can be, for example, a wireless communication connection or an optical fiber wired connection. The CT system also includes a data acquisition board 14 and a computer device 15. The data generated by the detector 11 is sent to the slip ring antenna 13 via the data collection board 12, and then stored in the computer device 15 for permanent storage by the data acquisition board 14. Among them, the data generated by different detectors 11 can be transmitted to each other through the data collection board 12.

[0054] In an exemplary embodiment, as shown in FIG2 , a data transmission method of a CT system is provided, which is described by taking the method applied to the computer device in FIG1 as an example, and includes S201 and S202. Wherein:

[0055] S201, determining at least one target slip ring antenna according to scanning transmission information of a CT system.

[0056] The scanning transmission information may include the current transmission mode of the CT system and the scanning type of the CT system.

[0057] In the embodiment of the present application, the current transmission mode of the CT system can be determined first, and when the current transmission mode is a single slip ring transmission mode, the scanning type of the CT system is obtained, and when the scanning type indicates that the CT system has at least one detector that does not generate data, the target slip ring antenna is determined. When the current transmission mode is a multi-slip ring transmission mode, the current transmission mode of the CT system is first switched to a single slip ring transmission mode, and then the step of obtaining the scanning type of the CT system is performed.

[0058] In a possible implementation, after the CT system starts the transmission mode, the transmission mode of the CT system may be directly initialized, that is, the current transmission mode may be directly controlled to be the single slip ring transmission mode. When the current transmission mode is the single slip ring transmission mode, the scanning type of the CT system is obtained, and when the scanning type indicates that the CT system has at least one detector that does not generate data, the target slip ring antenna is determined.

[0059] S202, controlling the first data collection board to transmit data to the second data collection board, so as to transmit data to the computer device through the slip ring antenna corresponding to the first data collection board and the target slip ring antenna; or transmitting data to the computer device through the target slip ring antenna;

[0060] The first data collection board is a data collection board of a transmission link where a detector generating data is located, and the second data collection board is a data collection board of a transmission link where a target slip ring antenna is located.

[0061] In an embodiment of the present application, as shown in FIG. 1 above, taking a dual-source CT system as an example, assuming that there is an idle target slip ring antenna (i.e., slip ring antenna B) in the dual-source CT system, the detector generating data is detector A, and the data m1+m2 generated by detector A is collected by data collection board A, and part of the data m2 is sent to data collection board B through data collection board A, data m1 is transmitted through slip ring antenna A, and data m2 is transmitted through slip ring antenna B, so that the data m1+m2 generated by detector A is sent to a computer device.

[0062] In a possible implementation, continuing with the above embodiment as an example, if the slip ring antenna A fails, the data collection board A will send all the data m1+m2 generated by the detector A to the data collection board B, and transmit the data m1+m2 to the computer device through the slip ring antenna B. That is, if the slip ring antenna A fails, the CT system will use the detector A, the data collection board A and the slip ring antenna B as backup data transmission links, and automatically enable the backup data transmission link. Optionally, the CT system will preset a backup data transmission link for each slip ring antenna, and once a failure of a slip ring antenna is detected, it will immediately switch to the backup data transmission link of the slip ring antenna to ensure the normal operation of the CT system.

[0063] In another possible implementation, it is assumed that the CT system is a three-source CT system, and it is assumed that there is a target slip ring antenna (i.e., slip ring antenna B) in an idle state in the three-source CT system, and the detectors that generate data are detectors A and detectors C. When data is transmitted, the data generated by detector A or part of the data generated by detector C can be transmitted to the computer device through the slip ring antenna B. For example, the data generated by detector C is transmitted to the computer device through the slip ring antenna B and the slip ring antenna C, and the data generated by detector A is transmitted to the computer device through the slip ring antenna A.

[0064] In another possible implementation, it is assumed that there are two target slip ring antennas (i.e., slip ring antenna B and slip ring antenna C) in an idle state in the CT system, and the detector that generates data is detector A. The data m1+m2+m3 generated by detector A can be sent to data collection board B through data collection board A, data m2 is transmitted through slip ring antenna B, data m3 is sent to data collection board C through data collection board C, and data m3 is transmitted through slip ring antenna C, so that the data m1+m2+m3 generated by detector A is transmitted to the computer device through slip ring antenna A, slip ring antenna B and slip ring antenna C. Alternatively, the data m1+m2+m3 generated by detector A is transmitted only through slip ring antenna A and one of the target slip ring antennas. For example, data m2 is sent to data collection board B or data collection board C through data collection board A, and data m1+m2+m3 generated by detector A is sent to the computer device through slip ring antenna A, slip ring antenna B / slip ring antenna C.

[0065] In the data transmission method of the above-mentioned CT system, at least one target slip ring antenna is determined according to the scanning transmission information of the CT system, and the first data collection board is controlled to transmit data to the second data collection board, so as to transmit data to the computer device through the slip ring antenna corresponding to the first data collection board and the target slip ring antenna; or, data is transmitted to the computer device through the target slip ring antenna; wherein the first data collection board is the data collection board of the transmission link where the detector generating the data is located, and the second data collection board is the data collection board of the transmission link where the target slip ring antenna is located. In the CT system of the embodiment of the present application, the data collection boards of the data transmission link are connected in communication. When it is determined according to the scanning transmission information of the CT system that the CT system has at least one target slip ring antenna in an idle state, multiple slip ring antennas can be used for data generated by the same detector for transmission, which can effectively improve the efficiency of data transmission. When the slip ring antenna corresponding to the detector fails, the target slip ring antenna can also be used to transmit the data generated by the detector, so that the CT system can scan normally, ensuring the accuracy and timeliness of data transmission, improving the quality of data transmission of the CT system, and the stability and reliability of the operation of the CT system.

[0066] FIG3 is a flow chart of a method for determining a target slip ring antenna in an embodiment, as shown in FIG3 , comprising the following steps:

[0067] S301, determining a current transmission mode of a CT system.

[0068] In the embodiment of the present application, the user can pre-set the transmission mode of the CT system. If it is the first scan, the current transmission mode of the CT system can be determined based on the operation instruction input by the user. Alternatively, the log file of each data transmission link in the CT system during the current data transmission is obtained, and the current transmission mode of the CT system is determined based on the log file.

[0069] S302: When the current transmission mode is the single slip ring transmission mode, obtain a scanning type of the CT system.

[0070] The single slip ring transmission mode is a mode in which the data generated by each detector is transmitted through a corresponding data transmission link.

[0071] Since doctors or technicians select appropriate scanning protocols based on the specific conditions of patients (such as weight, age, examination site, etc.), the scanning parameters in the scanning protocol include tube voltage, tube current, layer thickness, pitch, etc. These scanning parameters jointly determine the output intensity and quality of X-rays. Taking the dual-source CT system as an example, in the dual-source CT system, the two X-ray sources can be set with different tube voltages to produce X-ray beams of different energies. For example, one X-ray source may be set to 80kV and the other may be set to 140kV. This dual energy setting helps to distinguish between materials of different densities and improve image contrast and diagnostic accuracy.

[0072] In the embodiment of the present application, as shown in FIG4 , when the current transmission mode is the single slip ring transmission mode, the computer device can obtain the scanning type of the CT system according to the scanning protocol. Assuming that the CT system is a dual-source CT system, if the scanning protocol only includes the tube voltage and tube current of one tube, the scanning type of the CT system is single-source scanning.

[0073] Furthermore, when the transmission mode is a multi-slip ring transmission mode, the current transmission mode is controlled to switch to a single slip ring transmission mode, and a step of acquiring a scanning type of the CT system is performed.

[0074] The multi-slip ring transmission mode is a transmission mode in which the number of detectors generating data is less than the number of slip ring antennas.

[0075] In the embodiment of the present application, since the multi-slip ring transmission mode is not a common transmission mode for the CT system, after each scan is completed, the transmission mode needs to be switched back to the common single-slip ring transmission mode, and the next scan is triggered in the single-slip ring transmission mode. Therefore, when the current transmission mode is the multi-slip ring transmission mode, that is, the transmission mode has not been switched to the single-slip ring transmission mode after the last scan, the current transmission mode is first switched to the single-slip ring transmission mode, and then the above-mentioned step of obtaining the scan type of the CT system is performed.

[0076] S303: When the scan type indicates that the CT system has at least one detector that does not generate data, determine a target slip ring antenna.

[0077] In the embodiment of the present application, when the scanning type indicates that the CT system has at least one detector that does not generate data, that is, there is at least one X-ray source that does not perform scanning.

[0078] In a possible implementation, if there are multiple detectors that do not generate data, the transmission status information of the candidate slip ring antennas in the transmission link where all the detectors that do not generate data are located can be obtained, and the transmission status information of each candidate slip ring antenna is judged to obtain the target slip ring antenna.

[0079] In another possible implementation, the transmission state information of the candidate slip ring antenna in the transmission link where one of the detectors that did not generate data is located can be first obtained, and whether the candidate slip ring antenna is the target slip ring antenna is determined based on the transmission state information of the candidate slip ring antenna. If the candidate slip ring antenna is the target slip ring antenna, the transmission state information of the candidate slip ring antenna in the data transmission link corresponding to other subsequent detectors that did not generate data is not obtained and determined. If the candidate slip ring antenna is not the target slip ring antenna, the transmission state information of the candidate slip ring antenna in the transmission link where one of the detectors that did not generate data is located is obtained again until a target slip ring antenna is found.

[0080] When the scan type indicates that there is no detector that does not generate data in the CT system, each data transmission link transmits the data of the corresponding detector in a single slip ring transmission mode.

[0081] In an embodiment of the present application, a current transmission mode of a CT system is determined. When the current transmission mode is a single slip-ring transmission mode, a scanning type of the CT system is acquired. When the scanning type indicates that the CT system has at least one detector that does not generate data, a target slip-ring antenna is determined. In an embodiment of the present application, the target slip-ring antenna is determined based on the current transmission mode and the scanning type, thereby improving the efficiency and accuracy of determining the target slip-ring antenna.

[0082] FIG5 is a flow chart of a method for determining a target slip ring antenna in another embodiment. As shown in FIG5 , the embodiment of the present application relates to a possible implementation method of how to determine a target slip ring antenna, including the following steps:

[0083] S501, obtaining transmission status information of at least one candidate slip ring antenna; the candidate slip ring antenna is a slip ring antenna in a transmission link where a detector that has not generated data is located.

[0084] S502: For each candidate slip ring antenna, if the transmission state information indicates that the candidate slip ring antenna is in an idle state, determine the candidate slip ring antenna as a target slip ring antenna.

[0085] Since the data from the last scan may still be being transmitted, it is necessary to judge the transmission status information of the candidate slip ring antennas of each data transmission link. In an embodiment of the present application, various network monitoring tools can be used to obtain information such as network traffic and number of data packets of each data transmission link, and the transmission status information of the candidate slip ring antennas of the data transmission link can be judged based on information such as network traffic and number of data packets. If the transmission status information indicates that the candidate slip ring antenna is in an idle state, the candidate slip ring antenna is determined to be the target slip ring antenna; if the transmission status information of the candidate slip ring antenna indicates that the candidate slip ring antenna is in a non-idle state, the transmission status information of the candidate slip ring antenna can be obtained according to a preset period until the transmission status information indicates that the candidate slip ring antenna is in an idle state, and the candidate slip ring antenna is determined to be the target slip ring antenna.

[0086] In an embodiment of the present application, transmission status information of at least one candidate slip ring antenna is obtained; the candidate slip ring antenna is a slip ring antenna in a transmission link where a detector that has not generated data is located. For each candidate slip ring antenna, if the transmission status information indicates that the candidate slip ring antenna is in an idle state, the candidate slip ring antenna is determined to be a target slip ring antenna. In order to avoid the situation where the candidate slip ring antenna is transmitting data, when the detector does not generate data, the target slip ring antenna is further determined based on the transmission status information of the candidate slip ring antenna, thereby improving the accuracy of determining the target slip ring antenna and ensuring the stable operation of the CT system.

[0087] In one embodiment, the method further includes: determining test status information of the CT system; and when the test status information indicates that the CT system is in a non-test state, performing the step of determining a current transmission mode of the CT system.

[0088] In the embodiment of the present application, as shown in FIG6 , before the CT system performs a scan, the CT system needs to be tested. The step of performing the test before the scan includes: simultaneously detecting whether each data transmission link has no data being transmitted (i.e., check No. 1), if there is no data being transmitted, then starting the collection of test data for each data transmission link, if the test data can be collected normally, then stopping check No. 1, and the test is completed.

[0089] Therefore, before determining the current transmission mode of the CT system, it is necessary to determine that the CT system is not in a test state. As shown in FIG4 , it is determined whether the CT system currently has a No. 1 inspection in progress, or whether a data transmission link is transmitting data (i.e., No. 2 inspection). If there is No. 1 inspection or No. 2 inspection, then stop No. 1 inspection or No. 2 inspection. In the case that each transmission link in the CT system does not perform data transmission detection (i.e., there is no No. 1 inspection or No. 2 inspection), it is determined whether each transmission link collects test data. If no test data is collected, it is determined that the test state information of the CT system indicates that the CT system is in a non-test state; if test data is collected, it is determined that the test state information of the CT system indicates that the CT system is in a test state, and the computer device controls the CT system to stop collecting test data.

[0090] In an embodiment of the present application, test status information of the CT system is determined; when the test status information indicates that the CT system is in a non-test state, the step of determining the current transmission mode of the CT system is performed to ensure stable operation of the CT system.

[0091] In one embodiment, determining the test status information of the CT system includes: determining whether each transmission link collects test data when each transmission link in the CT system does not perform data transmission detection; and determining that the test status information indicates that the CT system is in a non-test state when each transmission link does not collect test data.

[0092] In the embodiment of the present application, as shown in FIG4, when each transmission link in the CT system does not perform data transmission detection, the data collection board will generate a log file in the process of collecting data, recording the collection status, error information, etc. The computer device can obtain the log file from the data collection board, and determine whether the test data is being collected by checking the log file. If the test data is not collected, the test status information indicates that the CT system is in a non-test state.

[0093] In the embodiment of the present application, when each transmission link in the CT system has not performed data transmission detection, it is determined whether each transmission link has collected test data; when each transmission link has not collected test data, it is determined that the test status information represents that the CT system is in a non-test state. Since the CT system needs to detect whether each data transmission link is transmitting test data before scanning, and collect test data to test the CT system, before the CT system is ready to start scanning, it is necessary to ensure that each transmission link has not performed a data transmission detection task and has not collected test data, thereby improving the accuracy of determining the non-test state.

[0094] FIG. 7 is a flow chart of a data transmission method of a CT system in another embodiment. As shown in FIG. 7 , the method includes the following steps:

[0095] S701, in the case where each transmission link in the CT system has not performed data transmission detection, determining whether each transmission link collects test data;

[0096] S702, when no test data is collected on each transmission link, determining that the test status information indicates that the CT system is in a non-testing state;

[0097] S703, determining the current transmission mode of the CT system;

[0098] S704, when the current transmission mode is the single slip ring transmission mode, obtaining a scanning type of the CT system;

[0099] S705, when the scan type indicates that the CT system has at least one detector that does not generate data, obtaining transmission state information of at least one candidate slip ring antenna; the candidate slip ring antenna is a slip ring antenna in a transmission link where the detector that does not generate data is located;

[0100] S706, for each candidate slip ring antenna, if the transmission state information indicates that the candidate slip ring antenna is in an idle state, determining the candidate slip ring antenna as a target slip ring antenna;

[0101] S707, controlling the first data collection board to transmit data to the second data collection board, so as to transmit data to the computer device through the slip ring antenna corresponding to the first data collection board and the target slip ring antenna; or transmitting data to the computer device through the target slip ring antenna;

[0102] The first data collection board is a data collection board of a transmission link where the detector generating the data is located, and the second data collection board is a data collection board of a transmission link where the target slip ring antenna is located;

[0103] S708, when the transmission mode is the multi-slip ring transmission mode, control the current transmission mode to switch to the single slip ring transmission mode, and execute the step of acquiring the scanning type of the source CT system.

[0104] In the embodiment of the present application, the data collection boards of the data transmission link in the CT system are connected in communication. When it is determined that the CT system has at least one target slip ring antenna in an idle state according to the scanning transmission information of the CT system, multiple slip ring antennas can be used to transmit the data generated by the same detector, which can effectively improve the efficiency of data transmission.
