Description

Technical Field

[0001] This application relates to the field of medical device technology, such as a data processing method and apparatus for medical devices, and medical devices. Background Technology

[0002] A CT (Computed Tomography) machine uses X-ray beams to perform tomographic scanning of the human body and, with the help of a computer, generates detailed images of the body's internal structures. The image reconstruction unit is the central component of the CT machine for image reconstruction. This unit receives data from various components, including the X-ray tube control unit, rotation control unit, scanning bed control unit, and data acquisition unit. To reconstruct an image, the data acquired by each component needs to be aligned in time.

[0003] The related technology discloses an alignment method, which includes: a rotation control unit, an X-ray tube control unit, and a scanning bed control unit transmitting their respective acquisition data to a synthesis unit of a data acquisition unit; the synthesis unit merging the acquisition data of the above units with the data of the detector unit; and then sending the data to an image reconstruction unit through an output unit such as a slip ring.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] CT scanners deploy images during the rotation of the X-ray tube; each deployment point can be considered a sampling point. Different components acquire data at different times, with the interval between sampling points (views) being called the sampledelay. Each component needs to transmit its acquired data to the synthesis unit within the sampledelay. The delay time of each component's information transmission channel has a fixed time difference and is limited by hardware bottlenecks, preventing further compression. As the sampledelay decreases, it becomes increasingly difficult to send the acquired data from each component to the synthesis unit within the sampledelay, thus achieving time alignment.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

It should be understood that such data can be interchanged where appropriate for the embodiments of this disclosure described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0034] Unless otherwise stated, the term "multiple" means two or more.

[0035] In this embodiment of the disclosure, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.

[0036] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0037] The term "correspondence" can refer to an association or binding relationship. The correspondence between A and B means that there is an association or binding relationship between A and B.

[0038] Currently, the main components of a CT scanner include the main control console, X-ray tube control unit, rotation control unit, scanning bed control unit, data acquisition unit, and image reconstruction unit.

[0039] The main control console is responsible for interfacing with the operator (user) and consists of at least input devices, display devices, audio / video interaction devices, and a computer host. Specifically, the main control console translates the operator's (user's) instructions into the configuration information and operational actions required by various components within the CT scanner, and provides feedback on the status of the instructions to achieve the operator's (user's) expected results.

[0040] The X-ray tube control unit is used to control the operation of the X-ray tube. It can adjust at least the X-ray tube voltage, current, focal spot, running time, and other elements, and record information such as voltage and current.

[0041] The rotation control unit is connected to the tilt drive mechanism of the CT scanner's support device and the rotation drive mechanism of the rotation device. It is used to control the rotation of the CT scanner, including slip ring speed control, rotation angle control, gantry tilt angle control, and other elements, and records information such as rotation angle, tilt angle, and speed.

[0042] The scanning bed control unit is connected to the scanning bed's drive mechanism and its peripheral devices. It controls the scanning bed's movement, including vertical movement, translation, and speed, and records information such as the bed code. Peripheral devices include gating devices, such as ECG gating and respiratory gating.

[0043] The data acquisition unit is connected to the detector and is used to receive the data information output by the detector. The detector collects the photons of the X-ray emitted by the X-ray tube after they have been attenuated by the scanned object, and converts the photons into data information. The detector includes one of a scintillator detector and a photon counting detector.

[0044] The image reconstruction unit synthesizes an image based on the data acquired by the data acquisition unit and the scanning bed control unit.

[0045] like Figure 1 This disclosure provides a data processing method for a medical device, the medical device including multiple components, including:

[0046] S201 controls the synchronization of the time of each component.

[0047] S202, insert the collected data from each component into the synchronization flag.

[0048] S203 aligns the collected data of each component by aligning the synchronization flags.

[0049] The data processing method for medical devices provided in this disclosure establishes a synchronization mechanism between the components of a CT scanner. A synchronization flag is inserted into the data acquired by each component, precisely recording the time of data generation. By aligning the synchronization flags, data from different components are matched and integrated in chronological order. This eliminates the need to transmit data from each component to the synthesis unit for alignment within the interval between adjacent sampling points, reducing hardware limitations and thus optimizing data acquisition efficiency and accuracy during CT scanning.

[0050] Specifically, time synchronization of each component can be achieved by acquiring the clock of each component. Furthermore, synchronization markers include, but are not limited to, timestamps, which are used to characterize elements that are unique on the time track, including year, month, day, minute, and second, and can be accurate to milliseconds.

[0051] Each component is responsible for acquiring the collected data and matching synchronization flag information, such as Figure 2 The data format shown is used to send information outwards. The content sent includes, but is not limited to, component identifiers, synchronization identifiers, and data information.

[0052] Figure 3This is a schematic diagram of an implementation environment for a data processing method for a medical device according to an embodiment of this disclosure. The implementation environment may also include a time synchronization control unit 100. The time synchronization control unit 200 is connected to the component unit 200. The component unit 200 may include multiple components, including but not limited to the X-ray tube control unit 201, rotation control unit 202, scanning bed control unit 203, and data acquisition unit 204 mentioned above. The time control unit 200 controls the synchronization of the time of the multiple components.

[0053] Optionally, controlling the time synchronization of each component includes: the time synchronization control unit sending its own first time to each component; each component synchronizing its time based on its own first time; wherein the first time of each component includes: the time difference between the time of each component and the time synchronization control unit, and the current time and value of the time synchronization control unit.

[0054] In this embodiment, the time synchronization control unit sends a time signal to each component. For any component, this time signal includes the time difference between the component's time and the time synchronization control unit, as well as the current time of the time synchronization control unit. Upon receiving the time signal, each component adjusts its own time, achieving time synchronization with the time synchronization control unit. Through this synchronization mechanism, each component can insert accurate synchronization flags when acquiring data, enabling precise alignment of the acquired data from different components during subsequent data integration. This significantly improves the accuracy of medical device data processing, ensures data synchronization and consistency, and avoids limitations in hardware transmission. The time difference between a component's time and the time synchronization control unit refers to the time difference between when the time synchronization control unit sends a signal through the transmission path and when the component receives the signal. The time difference between a component's time and the time synchronization control unit is determined by factors such as hardware transmission delay and software transmission delay.

[0055] Optionally, before the time synchronization control unit sends its respective first time to each component, the method further includes: the time synchronization control unit sending a first command to each component through a transmission path at a second time; each component, after receiving the first command, feeding back confirmation information that it has received the first command through a feedback path; when the time synchronization control unit receives the confirmation information, it records a third time; and the time synchronization control unit obtaining the time difference between the time of each component and the time synchronization control unit based on the second time, the third time, and the inherent delay of the feedback path.

[0056] A schematic diagram of the synchronization flag alignment mechanism is shown below. Figure 4As shown, ACK1, ACK2, ACK3, ACK4, and ACK5 form feedback paths. These feedback paths have a fixed (or known and controllable) transmission delay, similar to that of an RS-485 bus. The transmission delay is primarily affected by cable length, circuit board trace length, transmission rate, data processing time, and network topology; other factors are secondary and can be ignored. Cable length, circuit board trace length, transmission rate, and network topology are all electronic hardware design specifications and are known values. Data processing time is defined by the parsing chip; because it involves physical layer protocol parsing similar to RS-485 buses, its value is controllable and known. In conclusion, the transmission delays of ACK1, ACK2, ACK3, ACK4, and ACK5 can be calculated using algorithms based on existing known electronic circuits.

[0057] In this embodiment, the time synchronization control unit sends a first command to each component via a transmission path at a second time point to initiate the synchronization process. Upon receiving the first command, each component sends confirmation information that it has received the command back to the time synchronization control unit via a feedback path. Upon receiving the confirmation information, the time synchronization control unit records a third time point. Based on the second and third time points and the known inherent delay of the feedback path, the time synchronization control unit calculates the communication delay time difference with each component. Finally, the time synchronization control unit sends its own first time to each component, including the communication delay time difference and the control unit's current time. Each component adjusts its own time accordingly to achieve precise time synchronization. This process accurately measures and compensates for the communication delay between each component and the time synchronization control unit, ensuring the accuracy of the synchronization flags inserted by each component when collecting data. This allows for precise alignment of data from different components during data integration based on accurate synchronization flags.

[0058] Optionally, after each component synchronizes its time based on its own first time, the process further includes: the time synchronization control unit sending a second command to each component via a transmission path to record its own time at a fourth time; each component returning the fifth time recorded after receiving the second command to the time synchronization control unit via a feedback path; if the time difference between each component and the time synchronization control unit, the sum of the fourth time and the difference between the fifth time, are within a set threshold range, the time of each component has been synchronized.

[0059] In this embodiment, after each component completes time synchronization based on its respective first time, the time synchronization control unit sends a second command to each component through a transmission channel at a fourth time point, requesting each component to record its own time. Upon receiving the second command, each component records a fifth time point and returns it to the time synchronization control unit through a feedback channel. After receiving the fifth time returned by each component, the time synchronization control unit calculates the difference between the time difference between each component and the time synchronization control unit, the sum of the fourth time and the fifth time. If this difference is within a set threshold range, the time of each component is considered to have been successfully synchronized. This not only achieves time synchronization but also ensures the accuracy of the synchronization through the aforementioned verification mechanism.

[0060] Optionally, the time difference between the time of each component and the time synchronization control unit is acquired before each scan, at the factory, or according to a preset time period.

[0061] In this embodiment, if acquisition is selected before each scan, the time synchronization control unit sends a command to each component before each scan begins, requiring each component to record the time of receiving the command and feed it back to the control unit, thereby calculating the latest communication delay time difference. If acquisition is selected at the factory, a communication delay measurement is performed when the device leaves the production line, and the result is stored in the device for subsequent use. If acquisition is performed according to a preset time period, the time synchronization control unit automatically triggers the communication delay measurement process according to the set time period and updates the stored time difference data. This adapts to different usage environments and needs, ensuring the accuracy and real-time performance of time synchronization. Whether it is dynamic adjustment during device use, static configuration at the factory, or periodic updates, it ensures that the time of each component remains synchronized with the time of the control unit, thereby ensuring the accuracy of the data acquisition synchronization flag.

[0062] Optionally, such as Figure 4 As shown, the time synchronization control unit is the main control panel of the medical device.

[0063] In this embodiment, the main control console acts as a time synchronization control unit. Before the device starts up or before each scan, the main control console sends synchronization commands to each component and uses delay information to adjust the time of each component to ensure that the time of each component is synchronized with the main control console.

[0064] Optionally, the acquired data with synchronization flags from each component can be aligned within the synthesis unit in the relevant technology, and then the cooperative unit sends it to the image reconstruction unit for image reconstruction.

[0065] Optionally, each component includes a data acquisition unit connected to the detector, an X-ray tube control unit, a rotation control unit, and a scanning bed control unit. The medical device also includes an image reconstruction unit and a main control console. The acquisition data with synchronization markers from the X-ray tube control unit, the rotation control unit, and the scanning bed control unit are transmitted to the image reconstruction unit via the main control console. The acquisition data with synchronization markers from the data acquisition unit connected to the detector are directly transmitted to the image reconstruction unit. The image reconstruction unit aligns the acquisition data of each component by aligning the synchronization markers.

[0066] In this embodiment, the main control console sends synchronization commands to each component. Each component receives the command, records and reports the reception time, and the main control console calculates the communication delay and adjusts the time of each component to ensure time synchronization. The X-ray tube control unit, rotation control unit, and scanning bed control unit insert synchronization flags when acquiring data and transmit the data with the synchronization flags to the main control console, which then transmits it to the image reconstruction unit. Simultaneously, the data acquisition unit connected to the detector directly transmits its acquired data with synchronization flags to the image reconstruction unit. After receiving all data with synchronization flags, the image reconstruction unit aligns the acquired data from each component precisely using the synchronization flags, thereby synthesizing an accurate medical image.

[0067] Combination Figure 5 As shown, Figure 5 In the medical device, the image reconstruction unit 300 and the main control unit 101 can interact with each other. After receiving and processing data with synchronization flags from various components (X-ray tube control unit 201, rotation control unit 202, scanning bed control unit 203, and data acquisition unit 204), the image reconstruction unit 300 feeds back key information to the main control unit 101, including the data reconstruction status, the accuracy verification results of the synchronization flags, potential synchronization deviations, and data integrity check results. This feedback information enables the time synchronization control unit to evaluate the effectiveness of the current synchronization mechanism, adjust the time synchronization strategy in a timely manner, and ensure the accuracy of data acquisition and image reconstruction, thereby improving the overall performance of the medical device and the accuracy of diagnosis.

[0068] Optionally, each component includes a data acquisition unit connected to the detector, an X-ray tube control unit, a rotation control unit, and a scanning bed control unit. The medical device also includes an image reconstruction unit and a main control console. The X-ray tube control unit, the rotation control unit, and the scanning bed control unit, as well as the data acquisition unit connected to the detector, with synchronization flags, directly transmit the acquired data to the image reconstruction unit. The image reconstruction unit aligns the acquired data of each component by aligning the synchronization flags.

[0069] In this embodiment, each component generates data during task execution and attaches a synchronization flag to the data. This synchronization flag is synchronized by the main control console to ensure that the synchronization flags of all components are consistent. The X-ray tube control unit, rotation control unit, scanning bed control unit, and data acquisition unit directly send this data with the synchronization flag to the image reconstruction unit. The image reconstruction unit receives all this data and aligns it according to the synchronization flag, ensuring that all data is integrated based on the same time reference. Finally, the aligned data is used to reconstruct the image and generate a medical image.

[0070] like Figure 6 As shown, taking the data generated by the CT detector and the bed code of the scanning bed during a spiral scanning process as an example, once the X-ray tube begins to lay the wire, that is, during the continuous laying time, at the same sampling point, the attenuated data generated by the detector and the bed code need to correspond one-to-one. In related technologies, this correspondence requires data format conversion, data buffering, and data transmission during the synthesis unit's data synthesis process. The delays caused by these actions will affect the synchronization accuracy of the data generated by the CT detector and the bed code of the scanning bed within the synthesized data of the synthesis unit.

[0071] Based on the embodiments of this disclosure, the acquired data is inserted with an already aligned synchronization flag, and then the acquired data with the synchronization flag is transmitted to the image reconstruction unit. The image reconstruction unit can then perform image reconstruction on the data of the unified sampling point identified by the synchronization flag. In other words, based on the method provided by the embodiments of this disclosure, the delays caused by various actions of each component to the image reconstruction unit are not a concern due to the existence of the synchronization flag.

[0072] Furthermore, in related technologies, the data format output by the synthesis unit generally has a regular bit width, such as... Figure 7a and Figure 7b As shown, the data output by the synthesis unit includes a Header section and a Data section. The space occupied by the Header section is fixed, while the Data section varies depending on the scanning protocol. For example... Figure 7a As shown, in a scanning protocol, the space occupied by the Data section is larger than that occupied by the Header section, resulting in wasted space in the Header section. Figure 7b As shown, in another scanning protocol, the space occupied by the Data section is smaller than that occupied by the Header section, resulting in wasted space in the Data section.

[0073] The embodiments disclosed above use an image reconstruction unit to align the acquired data, eliminating the space waste of the Header and Data synthesis mechanism and making more effective use of cache space.

[0074] Combination Figure 8 As shown, this disclosure provides a data processing apparatus 60 for a medical device, including a processor 600 and a memory 601. Optionally, the apparatus 60 may further include a communication interface 602 and a bus 603. The processor 600, communication interface 602, and memory 601 can communicate with each other via the bus 603. The communication interface 602 can be used for information transmission. The processor 600 can call logical instructions in the memory 601 to execute the data processing method for a medical device described in the above embodiments.

The processor 600 executes functional applications and data processing by running the program instructions / modules stored in the memory 601, thereby implementing the data processing method for medical devices described above.
