[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.

In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0054] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0055] With the rapid development of medical systems and various types of medical imaging equipment, medical systems need to process more and more raw data of medical images. Among them, the raw data of medical images is acquired by medical imaging equipment in the medical system, and the raw data is transmitted to the data processing equipment in the medical system for data analysis, statistics, imaging and other processing.

[0056] However, the existing medical system first transmits and caches the raw data in the memory of the data processing device, and then transmits the raw data from the memory to the hard disk, so that when data processing is required, the raw data to be processed can be obtained from the hard disk. The above process is relatively time-consuming. In addition, since the raw data is stored in the memory of the CPU, and data processing mainly depends on the parallel processing of the GPU, before data processing, the data in the CPU memory needs to be transmitted or copied to the video memory of the GPU. The above data copying process is also very time-consuming. Therefore, the transmission efficiency of the raw data transmitted to the data processing device in the existing medical system is low.

[0057] After introducing the background technology of the image data processing method provided by the embodiment of the present application, the following briefly describes the implementation environment involved in the image data processing method provided by the embodiment of the present application. The image data processing method provided by the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the medical image acquisition device 101 communicates with the processing device 102 through the network. The data storage system can store the data that the processing device 102 needs to process. The data storage system can be integrated on the processing device 102, or it can be placed on the cloud or other network servers. Among them, the processing device 102 can be, but is not limited to, various personal computers, laptops, smart phones, tablets, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car devices, projection devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The head-mounted device can be a virtual reality (VR) device, an augmented reality (AR) device, smart glasses, etc. The processing device 102 can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services.

[0058] In one embodiment, Figure 2 As shown, a method for processing image data is provided, which is applied to Figure 1 The application to the processing device is taken as an example to illustrate, including the following steps:

[0059] S201, receiving a data stream sent by a medical image acquisition device.

[0060] Among them, the medical image acquisition device is used to collect the data stream of the medical system. The data stream refers to the raw data directly collected by the medical image acquisition device and not processed. The medical system may include but is not limited to any medical equipment system such as SPECT (Single-Photon Emission Computed Tomography), CT (Computed Tomography), PET (Positron Emission Computed Tomography), MR (Magnetic Resonance), PET-MR, PET-CT, XR (X-ray imaging system, X-ray), etc.

[0061] In an embodiment of the present application, a medical image acquisition device can acquire a data stream of a medical system, and then, optionally, the medical image acquisition device can directly send the data stream of the medical system to a processing device, so that the processing device can receive the data stream sent by the medical image acquisition device; or, the medical image acquisition device can also carry the data stream in a storage request and send a storage request to the processing device, so that the processing device can receive the storage request sent by the medical image acquisition device and parse the data stream from the storage request. Of course, the embodiment of the present application does not limit the specific implementation method of sending and / or receiving the data stream.

[0062] S202, performing data processing on the data stream while storing the data stream.

[0063] Among them, the data processing method may include but is not limited to at least one of raw data reconstruction, data analysis, data statistics, imaging, etc. In the embodiment of the present application, after receiving the data stream, the processing device may store the data stream, and / or the processing device may also perform data processing on the data stream. It should be noted that in the embodiment of the present application, when it is necessary to store and process the data stream, the storage and processing of the data stream may be performed in parallel. Exemplarily, the processing device may copy the received data stream to obtain two identical data streams, so that the processing device may store one data stream and perform data processing on all or part of the raw data in the other data stream.

[0064] In one embodiment, the “method for storing data stream” in S202 is as follows: Figure 3 As shown, including:

[0065] S301, receiving a storage request sent by a medical image acquisition device; the storage request includes a data stream and a logical storage address.

[0066] Among them, the storage request includes the data stream collected by the medical image acquisition device and the logical storage address. The storage request is used to instruct the data stream to be written into the processing device, and the logical storage address refers to the storage address of the data stream in the memory.

[0067] In the embodiment of the present application, the medical image acquisition device can acquire the data stream and determine the logical storage address where the data stream needs to be stored. After that, the medical image acquisition device can carry the data stream and the logical storage address corresponding to the data stream in the storage request and send the storage request to the processing device. Thus, the processing device can receive the storage request sent by the medical image acquisition device and parse the data stream and the logical storage address corresponding to the data stream from the storage request.

[0068] S302: Determine the physical storage address of the data stream according to the logical storage address and the preset mapping relationship.

[0069] The preset mapping relationship refers to the corresponding relationship between the logical storage address and the physical storage address, and the physical storage address refers to the storage address of the data stream in the hard disk.

[0070] In the embodiment of the present application, the processing device can predetermine a preset mapping relationship between the logical storage address and the physical storage address, so that the processing device can determine the physical storage address of the data stream corresponding to the logical storage address based on the logical storage address and the preset mapping relationship.

[0071] S303, storing the data stream to a physical storage address.

[0072] In an embodiment of the present application, the processing device can directly store the data stream to the physical storage address corresponding to the data stream through the DMA (Direct Memory Access) engine in the Field-Programmable Gate Array (FPGA) integrated inside the processing device. In this way, the storage capacity of raw data can be improved, the length of the entire storage link can be shortened, and abnormal problems existing in the raw data during the memory transfer process can be avoided, thereby improving the stability of machine storage.

[0073] In the above-mentioned image data processing method, a data stream sent by a medical image acquisition device is received; while storing the data stream, data processing is performed on the data stream; the way of storing the data stream includes: receiving a storage request sent by the medical image acquisition device; the storage request includes a data stream and a logical storage address; determining the physical storage address of the data stream according to the logical storage address and a preset mapping relationship; and storing the data stream to the physical storage address. Since the embodiment of the present application can perform data processing on the data stream while storing the data stream, there is no need to wait for the data stream to be stored before performing data processing, which can improve the efficiency of data processing. In addition, the embodiment of the present application can also predetermine the preset mapping relationship between the logical storage address and the physical storage address, so that when the processing device receives the data stream and the logical storage address sent by the medical image acquisition device, it can directly determine the physical storage address of the data stream according to the logical storage address and the preset mapping relationship, and directly store the data stream to the physical storage address corresponding to the data stream, without first caching the data stream to the memory and then storing it to the hard disk, so it can improve the efficiency of transmitting and storing the raw data in the medical image acquisition device to the processing device in the medical system.

[0074] In one embodiment, Figure 4 As shown, there is also provided a method for implementing data processing on the data stream, that is, the “data processing on the data stream” in the above S202, including:

[0075] S401, determine the type of data stream. If the type of data stream is a large data volume type, execute S402; if the type of data stream is a small data volume type, execute S403;

[0076] S402, transmitting the data stream to a graphics processor GPU for data processing; the data stream of large data volume type includes three-dimensional medical data.

[0077] S403, transmitting the data stream to the application layer of the processing device for data processing; the data stream of small data volume type includes myocardial perfusion curve data and electrocardiorespiration curve data.

[0078] Among them, the large data volume type refers to the type of data flow whose data volume is greater than the preset data volume threshold, and the data flow of the large data volume type may include but is not limited to three-dimensional medical data, etc. The small data volume type refers to the type of data flow whose data volume is less than or equal to the preset data volume threshold, for example, the data flow of the small data volume type may include but is not limited to at least one of the curve data such as myocardial perfusion curve data and electrocardiorespiration curve data. Of course, the specific value of the preset data volume threshold can be set according to actual conditions, and the embodiment of the present application does not limit this.

[0079] In an embodiment of the present application, the processing device can determine the type of the data stream according to the data volume or computational complexity of the data stream. If it is determined that the type of the data stream is a large data volume type, it means that the data volume of the data stream is large and / or the processing complexity is large. At this time, since the GPU has a good performance in parallel processing of raw data, the processing device can transmit the data stream to a graphics processing unit (GPU), thereby performing data processing on the data stream through the GPU. If it is determined that the type of the data stream is a small data volume type, it means that the data volume of the data stream is small and / or the processing complexity is small. At this time, transmitting the data stream to the GPU for data processing will waste the computing resources of the GPU, so the processing device can transmit the data stream to the application layer of the processing device, thereby performing data processing on the data stream through the application layer of the processing device.

[0080] In this embodiment, the type of data stream can be determined. If the type of data stream is a large data volume type, the data stream is transmitted to the graphics processor GPU for data processing; if the type of data stream is a small data volume type, the data stream is transmitted to the application layer of the processing device for data processing. In this way, the corresponding data processing method can be used for data processing according to the data volume and / or processing complexity of the data stream, so the efficiency of data processing on the data stream can be improved.

[0081] In one embodiment, a method for implementing data processing by a GPU is provided, namely, “transmitting the data stream to a graphics processor GPU for data processing” in the above S402, including:

[0082] The data stream is copied through an optical device to obtain a backup data stream corresponding to the data stream.

[0083] The backup data stream is transmitted to the GPU for data processing.

[0084] Since the data stream is stored in the hard disk in the CPU (Central Processing Unit) domain, and the video memory in the CPU domain and the GPU domain are not in the same address space, before the data stream of large data volume type is processed in parallel by the GPU, the data stream needs to be converted first. The relevant technology is to copy the data in the CPU domain memory to the GPU video memory. However, the data copy process is time-consuming and consumes machine performance. Based on this, in the embodiment of the present application, the processing device can use an optical device to copy and process the data stream in the process of receiving the data stream sent by the medical image acquisition device to obtain a backup data stream corresponding to the data stream. Afterwards, the processing device can use the Data Plane Development Kit (DPDK) to transfer the backup data stream corresponding to the data stream to the GPU's video memory, and process the data stream in parallel through the GPU to obtain the three-dimensional imaging result corresponding to the data stream. Among them, the optical device may include but is not limited to any one of the data splitters such as splitters, network cables, and optical fibers.

[0085] In this embodiment, since optical devices such as optical devices can copy data without loss, simply and quickly, and can achieve multiplexing, the embodiment of the present application uses optical devices to copy and process the data stream, avoiding the copying of raw data in the memory, and can improve the capacity and efficiency of raw data replication and transmission.

[0086] In one embodiment, a method for implementing data processing through an application layer is provided, that is, "transmitting the data stream to the application layer of a processing device for data processing" in the above S403, including:

[0087] A target data stream of a small data volume type is extracted from the data stream, and the target data stream is transmitted to the application layer for data processing through the storage space and registers of the logic controller in the processing device.

[0088] For data streams with small data volumes, when the activity is high, the data volume of the data stream accounts for a very small proportion of the total data volume, and the data content is simple and the computational complexity is low. Therefore, when processing data streams with small data volumes, high real-time requirements are required. At this time, if data processing is performed in the CPU, the real-time requirements cannot be met. If the data stream is transmitted to the GPU for data processing, the GPU's computing resources will be wasted.

[0089] Based on this, the embodiment of the present application can transfer a data stream of a small data volume type to the FPGA for data processing, that is, it can be understood that the processing device can divert the data stream through the logic controller (i.e., FPGA) in the processing device, and can extract the target data stream of a small data volume type from the data stream. Since the data volume of the data stream of the small data volume type is small, the present application does not need to occupy the PCIE (Peripheral Component Interconnect Express, a high-speed serial computer expansion bus standard) bus resources through the DMA method. The embodiment of the present application can store the target data stream of the small data volume type in the storage space in the FPGA, and then transfer and store the target data stream in the storage space to the register in the FPGA, thereby transmitting the target data stream to the application layer of the processing device through the register, and then, the application layer of the processing device can receive the target data stream according to the preset frequency, and can process the data stream through the application layer of the processing device. For example, the storage space can be a BAR space.

[0090] In this embodiment, a target data stream of a small data volume type can be extracted from the data stream through the FPGA, and the target data stream can be transmitted to the application layer for data processing through the storage space and registers of the logic controller in the processing device. Therefore, the target data stream of a small data volume type can be efficiently transmitted and processed through the FPGA.

[0091] In one embodiment, a method for implementing data processing through an application layer is also provided, that is, the above-mentioned image data processing method further includes:

[0092] An accelerator is used to accelerate the configuration of the register to obtain the configured register.

[0093] The above-mentioned “transmitting the target data stream to the application layer for data processing through the storage space and registers of the logic controller in the processing device” includes:

[0094] The target data stream is transferred to the application layer for data processing through the storage space and configured registers.

[0095] In an embodiment of the present application, the processing device may install an accelerator into the FPGA. For example, the accelerator may be inserted into the interface of the FPGA, and the accelerator may be used to accelerate the configuration of the register to obtain the configured register. Among them, the accelerator may include but is not limited to at least one of the hardware resources such as MiniPCIe and an accelerator stick, and the processing rate corresponding to the configured register is higher than the processing rate corresponding to the register (Register) before configuration. Afterwards, the processing device may transmit and store the target data stream of the small data type in the storage space to the configured register in the FPGA, and transmit the target data stream to the application layer of the processing device by means of the register, using the processing rate corresponding to the configured register. Then, the application layer of the processing device may receive the target data stream at a preset frequency, and may perform data processing on the data stream through the application layer of the processing device. Exemplarily, the data processing method may be: parallel processing of floating-point numbers in the target data stream, and Fourier transform processing of the target data stream to obtain a two-dimensional curve corresponding to the target data stream. In addition, if another curve needs to be drawn or a third-party curve needs to be accessed later, a register may be added to the FPGA. For example, another curve may be a VSM (Vibrating Sample Magnetometer) curve.

[0096] In this embodiment, an accelerator can be used to accelerate the configuration of registers to obtain configured registers, so that the target data stream is transmitted to the application layer through the storage space and the configured registers for data processing. In this way, the data processing process can be accelerated through FPGA and accelerator.

[0097] In an optional embodiment, if Figure 5 As shown, a method for processing image data is provided, which is applied to a processing device and includes:

In addition, the embodiment of the present application can also predetermine the preset mapping relationship between the logical storage address and the physical storage address, so that when the processing device receives the data stream and the logical storage address sent by the medical image acquisition device, it can directly determine the physical storage address of the data stream according to the logical storage address and the preset mapping relationship, and directly store the data stream to the physical storage address corresponding to the data stream, without first caching the data stream to the memory and then storing it to the hard disk, reducing the transmission module unit of the data link, so it can improve the efficiency of transmitting and storing the raw data in the medical image acquisition device to the processing device in the medical system, and improve the system stability.
