CT devices are complex diagnostic systems consisting primarily of many delicate electrical units that emit X-rays, such as bulbs, detectors, calibrators, high voltage generators, and the like. Conventional CT devices are typically equipped with an X-ray tube system and a detector system (i.e., single source CT) to acquire images of the body.

if, in step 204, the detection unit determines that the X-ray scanning device cannot be started normally when powered on, then the process proceeds to step 218, and in step 218, the detection unit detects whether the failed component of the first source unit and the second source unit is a collimator and/or a data measurer;
if in step 218 the detection unit determines that the malfunctioning component of the first and second source units is a collimator and/or a data measurer, proceeding to step 220, in step 220 the detection unit detects whether the malfunctioning collimator and/or data measurer comes from both the first and second source units;
if in step 220 the detection unit determines that the malfunctioning collimator and/or the data measurer is from both the first source unit and the second source unit, i.e. the detected malfunctioning component comprises at least one of the first collimator and the first data measurer of the first source unit and the detected malfunctioning component further comprises at least one of the second collimator and the second data measurer of the second source unit, the detection unit outputs a malfunction shutdown instruction and the method proceeds to step 222, in step 222 the control unit controls the X-ray scanning device to shutdown according to the malfunction shutdown mode instruction output by the detection unit and the notification unit may notify the user that the component needs to be replaced;

By the control method shown in fig. 2, when the X-ray scanning device is powered on, different operation mode adaptive changes can be realized through a system formed by software and/or hardware according to the following different scenes:
scene one: the start is successful:
1) if both the first source unit and the second source unit are available, the X-ray scanning device will operate as a normal dual source scanning device.
2) If only one of the first source unit and the second source unit is available, e.g. only the first source unit is operational, the second source unit may be excluded by confirmation of the operator (i.e. the operator is informed that "only the first source unit is operational"). The X-ray scanning device will then operate as a single source scanning device.
Scene two: failed start-up (failure from collimator and/or data measurer):
1) if both the first source unit and the second source unit fail, the X-ray scanning device fails to operate and the associated components need to be replaced.
2) If a failure occurs in only one source unit, for example, the collimator of the second source unit is defective while the first source unit is operational, the second source unit can be excluded by confirmation of the operator (i.e., the operator is notified that "only the first source unit is operational"). The X-ray scanning device will then operate as a single source scanning device.
Scene three: failed start-up (failure from bulb and/or high voltage generator):
1) for electrical safety reasons, the bulb and the high voltage generator have to be handled in different ways.
2) If neither the bulb and/or the high voltage generator of the first source unit nor the bulb and/or the high voltage generator of the second source unit is operational, the X-ray scanning device will be inoperable and the components must be replaced.
3) In case a failure comes from the bulb and/or the high voltage generator of the first source unit or a failure comes from the bulb and/or the high voltage generator of the second source unit and the failure is for example a defect in the anode rotation control of the second source unit, the operation of the X-ray scanning device is not allowed in order to protect the second bulb of the second source unit.
4) Allowing the X-ray scanning device to operate in single source mode if the failure is from the bulb and/or high voltage generator of the first source unit, or the failure is from the bulb and/or high voltage generator of the second source unit, e.g. the main inverter of the second source unit. The second source unit may then be excluded by confirmation by the operator (i.e. the operator is informed that "only the first source unit is operational"). The X-ray scanning device will then operate as a single source scanning device.
Further, it is also possible to create a computer program for causing hardware (for example, CPU, ROM, and RAM) built in the data processing apparatus to exhibit functions equivalent to the respective configurations of the control method according to the present embodiment described above. Further, a storage medium storing the computer program may also be provided.
As can be seen from the above-described solution, with such an automatic failure detection mechanism, even if a component fails, the X-ray scanning device can still operate as a single-source scanning device, which will reduce "down time" and prolong the usability and operability of the scanning device for patient examination.
Furthermore, when a component of the CT apparatus fails, it can be switched to the single-source mode according to the type of the failure, and then the CT apparatus can still operate and a patient examination can be performed. The self-adaptive dual-source/single-source CT equipment plays the advantages of dual-source CT to the utmost extent, namely, a set of imaging chain components are backed up at a client, the extra cost of a manufacturer and a client is not increased, and the system downtime is greatly reduced. The customer need not wait for the replacement of a defective part and need not backup a set of critical consumable spare parts (e.g., CT bulbs) on site to prevent system downtime due to bulb failure.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
