Description

Technical Field

[0001] The present invention relates to the field of computerized tomography (CT), and more particularly to an adaptive dual-source / single-source CT device. Background Art

[0002] CT technology is a commonly used detection technology in many fields such as medicine. A CT device is a complex diagnostic system mainly composed of many precision electrical units such as an X-ray tube that emits X-rays, a detector, a calibrator, and a high-voltage generator. Ordinary CT devices usually have a set of X-ray tube systems and a set of detector systems (i.e., single-source CT) to collect human body images.

[0003] However, in order to improve the temporal resolution and further improve the CT image quality, dual-source CT (DSCT) has been proposed currently. Dual-source CT is a CT device that simultaneously collects human body images through two sets of X-ray tube systems and two sets of detector systems.

[0004] However, whether it is single-source CT or dual-source CT, when components in the CT device fail, the system cannot operate normally. Therefore, customers cannot continue to use the CT device and must spend a considerable amount of time waiting for staff to replace the defective components. Summary of the Invention

[0005] In view of this, the present invention provides an X-ray scanning device, a control method of the X-ray scanning device, and a storage medium, which are directed to a dual-source CT device, can identify faults, and automatically adapt the system to a single-source scanning device (i.e., "single-tube mode") according to the fault type. Therefore, even when components fail, the CT scanning device can still operate and continue to perform patient examinations.

[0006] According to an embodiment of the present invention, an X-ray scanning device is provided, which is characterized in that it includes: a first source unit, including a first X-ray tube, a first high-voltage generator, a first collimator, and a first data measurer; a second source unit, including a second X-ray tube, a second high-voltage generator, a second collimator, and a second data measurer; a detection unit configured to perform the following operations according to whether the X-ray scanning device starts up normally when powered on: a) If the X-ray scanning device starts up normally when powered on, the detection unit detects whether both the first source unit and the second source unit are available. Wherein, when both the first source unit and the second source unit are available, the detection unit outputs a first mode instruction; when one of the first source unit and the second source unit is available, the detection unit outputs a second mode instruction; when neither the first source unit nor the second source unit is available, the detection unit outputs a third mode instruction; b) If the X-ray scanning device cannot start up normally when powered on, the detection unit detects the faulty component in the first source unit and the second source unit, and outputs one of the first mode instruction, the second mode instruction, and the third mode instruction according to the faulty component; a confirmation unit configured to, when the detection unit outputs the second mode instruction, present the second mode instruction to the user of the X-ray scanning device and receive the user's response to the second mode instruction; and a control unit configured to: when the detection unit outputs one of the first mode instruction and the third mode instruction, control the X-ray scanning device to operate according to the mode instruction output by the detection unit, and when the detection unit outputs the second mode instruction and the user's response from the confirmation unit to the second mode instruction is acceptance, control the X-ray scanning device to operate according to the second mode instruction.

[0007] The above structure can implement an automatic detection mechanism, automatically identify the system fault / error type, and configure the dual-source scanning device as a single-source scanning device (i.e., "single X-ray tube mode") according to the existing fault.

[0008] Preferably, if the X-ray scanning device fails to start properly when powered on, the detection unit detects whether the faulty component in the first source unit and the second source unit is at least one of the first X-ray tube, the first high-voltage generator, the first collimator, the first data measurer, the second X-ray tube, the second high-voltage generator, the second collimator, and the second data measurer, and outputs one of a first mode instruction, a second mode instruction, and a third mode instruction according to the type of the detected faulty component: b1) If the detected faulty component is at least one of the first collimator and the first data measurer of the first source unit, or the detected faulty component is at least one of the second collimator and the second data measurer of the second source unit, the detection unit outputs the second mode instruction; b2) If the detected faulty component is each of the first collimator, the first data measurer, the second collimator, and the second data measurer, the detection unit outputs the third mode instruction; b3) If the detected faulty component is at least one of the first X-ray tube and the first high-voltage generator of the first source unit, or the detected faulty component is at least one of the second X-ray tube and the second high-voltage generator of the second source unit, the detection unit determines whether the fault type of the faulty component belongs to a predetermined error set. If the fault type belongs to the predetermined error set, the detection unit outputs the third mode instruction. If the fault type does not belong to the predetermined error set, the detection unit outputs the second mode instruction; b4) If the detected faulty component includes at least one of the first X-ray tube and the first high-voltage generator of the first source unit, and the detected faulty component also includes at least one of the second X-ray tube and the second high-voltage generator of the second source unit, the detection unit outputs the third mode instruction.

[0012] Preferably, according to the third mode instruction, the X-ray scanning device is in a fault shutdown state.

[0013] The above structure can maximize the advantages of dual-source CT, which is equivalent to backing up a set of imaging chain components on the client side, without increasing the additional costs for the manufacturer and the customer, and greatly reducing the "system downtime". The customer does not need to wait for a long time to replace defective parts.

[0014] Preferably, the X-ray scanning device further includes: a security unit configured to store a set of predetermined errors, and a detection unit accesses the security unit to compare the fault type of the faulty component with the set of predetermined errors stored in the security unit to determine whether the fault type of the faulty component belongs to the set of predetermined errors.

If the fault type belongs to the predetermined error set, the detection step outputs the third mode instruction. If the fault type does not belong to the predetermined error set, the detection step outputs the second mode instruction; b4) If the detected faulty component includes at least one of the first tube and the first high-voltage generator of the first source unit, and the detected faulty component also includes at least one of the second tube and the second high-voltage generator of the second source unit, the detection step outputs the third mode instruction.

[0023] Preferably, according to the first mode instruction, the X-ray scanning device operates in a normal state, in which both the first source unit and the second source unit are in an operating state.

[0060] To make the objectives, technical solutions and advantages of the present invention clearer, the following examples are given to further elaborate on the present invention in detail.

[0061] It should be noted that, without conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0062] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meanings as those commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0063] In the present invention, unless otherwise stated, the orientation terms such as "upper, lower, top, bottom" are usually in relation to the directions shown in the drawings, or in relation to the vertical, perpendicular or gravitational directions of the components themselves; similarly, for ease of understanding and description, "inner, outer" refer to the inner and outer of the contours of the components themselves, but the above orientation terms do not limit the present invention.

[0064] Figure 1 Schematic block diagram of an X-ray scanning device according to an embodiment of the present invention. As Figure 1 shown, the X-ray scanning device 10 mainly includes:

[0065] 1) The first source unit 102, the first source unit includes a first tube, a first high-voltage generator, a first collimator, a first data measurement device (DMS);

[0066] 2) The second source unit 104, which includes a second X-ray tube, a second high-voltage generator, a second collimator, and a second data measurer. The first source unit 102 and the second source unit 104 can be arranged on the same turntable.

[0067] 3) The detection unit 106. When the X-ray scanning device 10 is powered on and starts up normally, the detection unit performs the following operations: If the X-ray scanning device 10 starts up normally when powered on, the detection unit 106 checks whether both the first source unit 102 and the second source unit 104 are available. When both the first source unit 102 and the second source unit 104 are available, the detection unit 106 outputs a normal state instruction, in which the dual-source mode and the single-source mode are included, and both the first source unit 102 and the second source unit 104 are in the working state. When only one of the first source unit 102 and the second source unit 104 is available, the detection unit 106 outputs a single-source mode instruction. In the single-source mode, only one of the first source unit 102 and the second source unit 104 (i.e., the available source unit of the first source unit 102 and the second source unit 104) is in the operating state. When neither the first source unit 102 nor the second source unit 104 is available, the detection unit 106 outputs a fault shutdown mode instruction, in which the X-ray scanning device 10 is in the shutdown state. Additionally, if the X-ray scanning device 10 fails to start up normally when powered on, the detection unit 106 checks the components that have failed in the first source unit 102 and the second source unit 104 (i.e., checks the first X-ray tube, the first high-voltage generator, the first collimator, the first data measurer, the second X-ray tube, the second high-voltage generator, the second collimator, and the second data measurer), and outputs one of the normal state instruction, the single-source mode instruction, and the fault shutdown mode instruction according to the failed component. This operation will be described in detail later with reference to the appendix. Figure 2 This operation will be described in detail later.

[0068] 4) The confirmation unit 108. When the detection unit 106 outputs a single-source mode instruction, it presents the single-source mode instruction to the user of the X-ray scanning device 10 and receives the user's response to the single-source mode instruction. For example, the user's response to the single-source mode instruction can include accepting or rejecting the single-source mode instruction.

[0069] 5) A safety unit 110, in which a predetermined set of errors is stored. For example, the predetermined set of errors includes an anode rotation control error of the first X-ray tube and an anode rotation control error of the second X-ray tube. And when the detection unit 106 detects a faulty component, the detection unit 106 accesses the safety unit 110. The detection unit 106 compares the fault type of the faulty component with the predetermined set of errors stored in the safety unit 110 to determine whether the fault type of the faulty component belongs to the predetermined set of errors;

[0070] 6) A notification unit 112, according to the detection result of the detection unit 106, notifies the user of the X-ray scanning device 10 of at least one of the following: the fault type of the faulty component in the first source unit 102 and the second source unit 104, the component that needs to be replaced in the first source unit 102 and the second source unit 104, the detection type currently applicable to the X-ray scanning device 10;

[0071] 7) A control unit 114, when the detection unit 106 outputs one of a normal state instruction and a fault shutdown mode instruction, controls the X-ray scanning device 10 to operate according to the mode instruction output by the detection unit 106, and when the detection unit 106 outputs a single-source mode instruction and the response of the user from the confirmation unit 108 to the single-source mode instruction is acceptance, controls the X-ray scanning device 10 to operate according to the single-source mode instruction.

[0072] Next, with reference to Figure 2 the flowchart of the control method of the X-ray scanning device according to an embodiment of the present invention shown in Figure 2 as shown, the control method includes:

[0073] Step 202: Power on the X-ray scanning device;

[0074] Step 204: The detection unit determines whether the X-ray scanning device starts up normally when powered on;

[0075] If in step 204, the detection unit determines that the X-ray scanning device starts up normally when powered on, then proceed to step 206. In step 206, the detection unit determines whether both the first source unit and the second source unit are available;

[0076] If in step 206, the detection unit determines that both the first source unit and the second source unit are available, then proceed to step 216. In step 216, the detection unit outputs a normal state instruction, and then the control unit controls the X-ray scanning device to operate in a normal state according to the normal state instruction output by the detection unit. The normal state includes a dual-source mode and a single-source mode, and both the first source unit and the second source unit are in an operating state;

[0077] If in step 206, the detection unit determines that not both the first source unit and the second source unit are available, then proceed to step 208. In step 208, the detection unit determines whether one of the first source unit and the second source unit is available;

[0078] If in step 208, the detection unit determines that one of the first source unit and the second source unit is available (for example, the first source unit is available), then proceed to step 210. In step 210, the detection unit outputs a single-source mode instruction to configure the X-ray scanning device as a single-source scanning device (for example, perform single-source scanning using the first source unit), and then proceed to step 212. In step 212, the confirmation unit presents the single-source mode instruction to the user of the X-ray scanning device and receives the user's response to the single-source mode instruction. If in step 212, the confirmation unit receives the user's response to the single-source mode instruction as accepting the single-source mode instruction, then proceed to step 214. In step 214, the control unit controls the X-ray scanning device to operate in the single-source mode (for example, perform single-source scanning using the first source unit). If in step 212, the confirmation unit receives the user's response to the single-source mode instruction as rejecting the single-source mode instruction, then proceed to step 222. In step 222, the control unit controls the X-ray scanning device to stop, and the notification unit can notify the user that a component needs to be replaced;

[0079] If in step 208, the detection unit determines that neither the first source unit nor the second source unit is available, then the detection unit outputs a fault shutdown instruction, and the method proceeds to step 222. In step 222, the control unit controls the X-ray scanning device to stop according to the fault shutdown mode instruction output by the detection unit, and the notification unit can notify the user that a component needs to be replaced;

[0080] If in step 204, the detection unit determines that the X-ray scanning device cannot start normally when powered on, then proceed to step 218. In step 218, the detection unit detects whether the faulty component in the first source unit and the second source unit is the collimator and / or the data measurer;

[0081] If in step 218, the detection unit determines that the faulty component in the first source unit and the second source unit is the collimator and / or the data measurer, then proceed to step 220. In step 220, the detection unit detects whether the faulty collimator and / or data measurer comes from both the first source unit and the second source unit;

[0082] If in step 220, the detection unit determines that the malfunctioning collimator and / or data measurer are from both the first source unit and the second source unit, that is, the detected malfunctioning components include at least one of the first collimator and the first data measurer of the first source unit, and the detected malfunctioning components also include at least one of the second collimator and the second data measurer of the second source unit, then the detection unit outputs a fault shutdown instruction, and the method proceeds to step 222. In step 222, the control unit controls the X-ray scanning device to shut down according to the fault shutdown mode instruction output by the detection unit, and the notification unit can notify the user that component replacement is required;

[0083] If in step 220, the detection unit determines that the malfunctioning collimator and / or data measurer are from one of the first source unit and the second source unit. For example, if the malfunctioning collimator and / or data measurer are from the second source unit, then it proceeds to step 224. In step 224, the detection unit outputs a single-source mode instruction to configure the X-ray scanning device as a single-source scanning device (e.g., perform single-source scanning using the first source unit). Next, it proceeds to step 226. In step 226, the confirmation unit presents the single-source mode instruction to the user of the X-ray scanning device and receives the user's response to the single-source mode instruction. If in step 226 the confirmation unit receives the user's response to the single-source mode instruction as accepting the single-source mode instruction, then it proceeds to step 228. In step 228, the control unit controls the X-ray scanning device to operate in single-source mode;

[0084] If in step 218, the detection unit determines that the malfunctioning components in the first source unit and the second source unit are not collimators and / or data measurers, then it proceeds to step 230. In step 230, the detection unit detects whether the malfunctioning components are from at least one of the first tube and the first high-voltage generator of the first source unit, and at least one of the second tube and the second high-voltage generator of the second source unit, that is, the detection unit detects whether at least one of the first tube and the first high-voltage generator of the first source unit malfunctions, and whether at least one of the second tube and the second high-voltage generator of the second source unit also malfunctions;

[0085] If in step 230, the detection unit determines that the malfunctioning components include at least one of the first tube and the first high-voltage generator of the first source unit and at least one of the second tube and the second high-voltage generator of the second source unit, then the detection unit outputs a fault shutdown mode instruction, and the method proceeds to step 234. In step 234, the control unit controls the X-ray scanning device to shut down according to the fault shutdown mode instruction output by the detection unit, and the notification unit can notify the user that component replacement is required;

[0086] If in step 230, the detection unit determines that the faulty component comes from at least one of the first X-ray tube and the first high-voltage generator of the first source unit or from at least one of the second X-ray tube and the second high-voltage generator of the second source unit. For example, if the second X-ray tube and / or the second high-voltage generator of the second source unit fails, while the first X-ray tube and the first high-voltage generator of the first source unit are fault-free, then proceed to step 232. In step 232, the detection unit determines whether the fault type of the faulty component belongs to a predetermined error set. For example, whether the fault type of the faulty second X-ray tube and / or the second high-voltage generator of the second source unit belongs to the predetermined error set;

[0087] If in step 232, the detection unit determines that the fault type belongs to the predetermined error set (for example, when the second X-ray tube of the second source unit fails, the detection unit determines that the fault type is the anode rotation control error of the second X-ray tube, and the detection unit determines that this fault type belongs to the predetermined error set by accessing the security unit), then the detection unit outputs a fault shutdown mode instruction, and the method proceeds to step 234. In step 234, the control unit controls the X-ray scanning device to shut down according to the fault shutdown mode instruction output by the detection unit, and the notification unit can notify the user that a component needs to be replaced;

[0088] If in step 232, the detection unit determines that the fault type does not belong to the predetermined error set (for example, when the second X-ray tube of the second source unit fails, the detection unit determines that the fault type is the main inverter fault of the second X-ray tube, and the detection unit determines that this fault type does not belong to the predetermined error set by accessing the security unit), then proceed to step 224. In step 224, the detection unit outputs a single-source mode instruction to configure the X-ray scanning device as a single-source scanning device (for example, using the first source unit). Next, proceed to step 226. In step 226, the confirmation unit presents the single-source mode instruction to the user of the X-ray scanning device and receives the user's response to the single-source mode instruction. If in step 226 the confirmation unit receives the user's response to the single-source mode instruction as accepting the single-source mode instruction, then proceed to step 228. In step 228, the control unit controls the X-ray scanning device to operate according to the single-source mode instruction; if in step 226 the confirmation unit receives the user's response to the single-source mode instruction as rejecting the single-source mode instruction, then proceed to step 222. In step 222, the control unit controls the X-ray scanning device to shut down, and the notification unit can notify the user that a component needs to be replaced.

[0089] By the control method shown in the appendix Figure 2 When the X-ray scanning device is powered on, through the system composed of software and / or hardware, different operation modes can be adaptively changed according to the following different scenarios:

[0090] Scenario 1: Successful startup:

[0091] 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.

[0092] 2). If only one of the first source unit and the second source unit is available, for example, only the first source unit is operable, the second source unit can be excluded through the operator's confirmation (i.e., notify the operator that "only the first source unit is operable"). After that, the X-ray scanning device will operate as a single-source scanning device.

[0093] Scenario 2: Startup failure (fault from the collimator and / or data measurer):

[0094] 1). If both the first source unit and the second source unit fail, the X-ray scanning device cannot operate and relevant components need to be replaced.

[0095] 2). If the fault occurs only in one source unit, for example, the collimator of the second source unit is defective while the first source unit is operable, the second source unit can be excluded through the operator's confirmation (i.e., notify the operator that "only the first source unit is operable"). After that, the X-ray scanning device will operate as a single-source scanning device.

[0096] Scenario 3: Startup failure (fault from the tube and / or high-voltage generator):

[0097] 1). For electrical safety reasons, the tube and the high-voltage generator must be handled in different ways.

[0098] 2). If the tube and / or high-voltage generator of the first source unit and the tube and / or high-voltage generator of the second source unit both cannot work, then the X-ray scanning device will not work and components must be replaced.

[0099] 3). If the fault comes from the tube and / or high-voltage generator of the first source unit, or the fault comes from the tube and / or high-voltage generator of the second source unit, and the fault is, for example, a defective anode rotation control of the second source unit, the X-ray scanning device is not allowed to operate to protect the second tube of the second source unit.

[0100] 4). If the fault comes from the tube and / or high-voltage generator of the first source unit, or the fault comes from the tube and / or high-voltage generator of the second source unit, for example, a main inverter fault of the second source unit, the X-ray scanning device is allowed to operate in single-source mode. Then the second source unit can be excluded through the operator's confirmation (i.e., notify the operator that "only the first source unit is operable"). After that, the X-ray scanning device will operate as a single-source scanning device.

[0101] In addition, a computer program can be created to cause the hardware (e.g., CPU, ROM, and RAM) built into the data processing device to exhibit functions equivalent to the corresponding configurations of the control method according to the above-described embodiment. In addition, a storage medium storing the computer program can be provided.

[0102] As can be seen from the above solution, through this automatic fault detection mechanism, even if a component fails, the X-ray scanning device can still operate as a single-source scanning device, which will reduce the "downtime" and extend the availability and operability of the scanning device for patient examinations.

[0103] In addition, when a component of the CT device fails, it can be switched to the single-source mode according to the type of failure, and then the CT device can still operate and patient examinations can be performed. This adaptive dual-source / single-source CT device maximizes the advantages of dual-source CT, equivalent to backing up a set of imaging chain components at the client side, without increasing the additional costs for the manufacturer and the customer, and significantly reducing the "system downtime". The customer does not need to wait for defective parts to be replaced, and the customer does not need to keep a set of critical consumable spare parts (such as CT tubes) on site in case the system stops due to tube failure.

[0104] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
