[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0045] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0046] Firstly, such as Figure 1 As shown, this application provides an electrical control system applied to a SPECT-CT device 1. The SPECT-CT device 1 includes a host computer 40, a CT detector 101, and a probe mechanism 201. A SPECT detector 204 is mounted on the probe mechanism 201. The electrical control system includes:

[0047] Power module 2 is connected to CT detector 101 and SPECT detector 204;

[0048] Signal conditioning module 3 is connected to CT detector 101 and host computer 40, and is used to condition the signals detected and acquired by CT detector 101 and send them to host computer 40.

[0049] The fault detection module 4 is used to monitor the operating parameters of the SPECT-CT device 1 to confirm whether the SPECT-CT device 1 has malfunctioned, and to issue an alarm when the SPECT-CT device 1 malfunctions.

[0050] Safety protection module 5, connected to fault detection module 4 and probe mechanism 201, is used to retract or stop probe mechanism 201 when SPECT-CT device 1 generates a fault related to probe mechanism 201.

[0051] Specifically, the CT detector 101 can be any existing detector used to detect and acquire information about the subject during CT scans based on SPECT-CT equipment, and the SPECT detector 204 can be any existing detector used to detect and acquire information about the subject during SPECT scans based on SPECT-CT equipment.

[0052] More specifically, signal conditioning can be existing signal conditioning processing methods such as amplifying, filtering, or converting analog signals into digital signals.

[0053] More specifically, the fault detection module 4 may include devices such as temperature sensors, voltmeters, and ammeters that can be used to monitor operating parameters of the SPECT-CT device 1. When the probe mechanism 201 includes a motor, the fault detection module 4 may also include an existing detection mechanism for monitoring the torque of the motor in the probe mechanism 201. The fault detection module 4 can determine that the SPECT-CT device 1 has a fault related to the probe mechanism 201 when it detects that the operating parameters of the probe mechanism 201 are not within a specific range. The devices or mechanisms included in the fault detection module 4 can be set at any location that can monitor the corresponding operating parameters of the SPECT-CT device 1.

[0054] More specifically, the safety protection module 5 may include devices such as relays that can cause the probe mechanism 201 to retract or stop operating.

[0055] More specifically, this application provides a power supply module 2 and a signal conditioning module 3, which can supply power to the CT detector 101 and the SPECT detector 204, and can condition the signals detected by the CT detector 101, thereby improving the accuracy and stability of the signals detected by the CT detector 101, and facilitating the processing of the signal-conditioned signals by the host computer 40.

[0056] More specifically, this application includes a fault detection module 4, which can issue an alarm when the SPECT-CT equipment 1 malfunctions, facilitating timely notification to staff. Furthermore, when the SPECT-CT equipment 1 malfunctions related to the probe mechanism 201, it can work with the safety protection module 5 to retract or stop the probe mechanism 201, thereby preventing the probe mechanism 201 from impacting or squeezing the patient. Therefore, this application can only retract or stop the probe mechanism 201 when a malfunction occurs, thus enabling a corresponding response based on the type of malfunction.

[0057] The electrical control system provided in this application can power the CT detector 101 and the SPECT detector 204, thereby improving the accuracy and stability of the signals detected and acquired by the CT detector 101. Furthermore, this application can automatically detect faults, with a high degree of automation and stability. Moreover, this application can respond accordingly to the type of fault generated by the SPECT-CT device 1, demonstrating high flexibility.

[0058] In some preferred embodiments, the fault detection module 4 includes:

[0059] Monitoring component 41 is used to monitor the operating parameters of various components of the SPECT-CT device 1;

[0060] The fault diagnosis component 42 is connected to the monitoring component 41 and the safety protection module 5, and is used to determine whether the corresponding SPECT-CT equipment 1 has a fault based on the operating parameters.

[0061] Alarm component 43, connected to fault diagnosis component 42, is used to issue an alarm when a component of SPECT-CT device 1 malfunctions.

[0062] Specifically, the various components of the SPECT-CT device 1 may be components in the SPECT-CT device 1 such as the CT detector 101, the probe mechanism 201, and the SPECT detector 204.

[0063] More specifically, the fault diagnosis component 42 determines that the SPECT-CT device 1 has malfunctioned when it detects that the operating parameters of each component in the SPECT-CT device 1 are not within a specific range.

[0064] In this embodiment, the electrical control system of this application is equipped with a monitoring component 41, a fault judgment component 42, and an alarm component 43, which enables the fault detection module 4 to determine the fault type and perform corresponding actions according to the fault type when the SPECT-CT equipment 1 malfunctions.

[0065] like Figure 2 As shown, in some preferred embodiments, the monitoring component 41 includes a distance sensor 411, a tactile switch 412, and a pressure sensor 413, all of which are mounted on the probe mechanism 201.

[0066] Specifically, the distance sensor 411 detects the distance between itself and the subject to detect the distance between the probe mechanism 201 and the subject. Therefore, the distance sensor 411 can trigger the safety protection module 5 when the probe mechanism 201 is too close to the subject, thereby preventing the probe mechanism 201 from impacting or squeezing the subject. The tactile switch 412 is triggered when slightly touched. Therefore, the tactile switch 412 can trigger the safety protection module 5 when it touches the subject, thereby preventing the probe mechanism 201 from impacting or squeezing the subject and causing injury to the subject if the distance sensor 411 fails. The pressure sensor 413 is used to detect pressure. Therefore, the pressure sensor 413 can trigger the safety protection module 5 when the subject exerts a certain pressure on the probe mechanism 201, thereby preventing the probe mechanism 201 from impacting or squeezing the subject and causing injury to the subject if both the distance sensor 411 and the tactile switch 412 fail. Therefore, in this embodiment, the electrical control system of this application can fully protect the subject based on multiple safety measures and can prevent injury to the subject caused by the failure of the probe mechanism 201.

[0071] Specifically, the rated voltages of CT detector 101 and SPECT detector 204 are generally high. Therefore, in this embodiment, the electrical control system of this application can provide high voltage to CT detector 101 and SPECT detector 204, thereby improving the stability and accuracy of the signals detected and acquired by CT detector 101 and SPECT detector 204.

[0072] In some preferred embodiments, the SPECT-CT device 1 further includes a collimator 102, an X-ray tube assembly 103 for emitting X-rays, and a collimator 203;

[0073] The high-voltage power supply module 21 is also used to power the beam limiter 102, the X-ray tube assembly 103 and the collimator 203.

[0074] Specifically, the collimator 102 is used to limit the radiation range of the X-rays emitted by the X-ray tube assembly 103 to protect the subject, and the collimator 203 is used to allow only rays in a specific incident direction to pass through in order to improve the clarity of the images detected and acquired by the SPECT detector 204.

[0075] More specifically, the rated voltages of the collimator 102, X-ray tube assembly 103, and collimator 203 are generally high. Therefore, in this embodiment, the electrical control system of this application can provide high voltage to the collimator 102, X-ray tube assembly 103, and collimator 203, thereby improving the working performance of the collimator 102, X-ray tube assembly 103, and collimator 203, thus better protecting the examinee and making the images detected and acquired by the SPECT detector 204 clearer.

[0076] like Figure 4 As shown, preferably, there are multiple collimators 203, and the signal conditioning module 3 is connected to the CT detector 101 and all the collimators 203 in a one-to-one correspondence.

The first voltage conversion module 212 is used to convert the voltage output by the high-voltage power supply 211 according to the rated voltage of the SPECT detector 204 and the collimator 203. The second voltage conversion module 214 is used to convert the voltage output by the high-voltage power supply 211 according to the rated voltage of the CT detector 101 and the collimator 102.

[0081] Specifically, the first voltage conversion module 212 and the second voltage conversion module 214 may include transformers or other existing devices capable of voltage conversion.

[0086] The output terminals of the first phase line L1 and the second phase line L2 are both connected to the SPECT detector 204 and the collimator 203 through the first voltage conversion module 212.

[0087] In this embodiment, the electrical control system of this application is provided with a first phase line L1, a second phase line L2 and a third phase line L3, which can provide the required voltage to each device in the SPECT-CT equipment 1 respectively.
