[0023] Below, the exemplary embodiments according to the present invention will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments of the present invention, and it should be understood that the present invention is not limited to the exemplary embodiments described here.

[0024] Figure 1 FIG. 2 is a schematic diagram of the structure of an ultrasound system provided by an exemplary embodiment of the present invention. Figure 1 As shown, the ultrasound system 10 provided in the embodiment of the present invention includes a front-end device 11 and a cloud imaging device 12 connected to the front-end device 11 by signal. Specifically, the front-end device 11 is used to determine ultrasound control information capable of controlling the ultrasound signal emitted by the ultrasound probe, and to generate an ultrasound imaging signal that meets a preset condition based on an ultrasound echo signal corresponding to the ultrasound signal emitted by the ultrasound probe. The cloud imaging device 12 is used to generate ultrasound image information based on the ultrasound imaging signal generated by the front-end device 11.

[0025] Exemplarily, the preset condition refers to the signal being in a digital signal form. For example, the front-end device 11 converts the ultrasonic echo signal in the form of an analog signal recovered by the ultrasonic probe into an ultrasonic imaging signal in the form of a digital signal.

[0026] Exemplarily, the ultrasound control information refers to control sequence information capable of controlling an ultrasound beam emitted by an ultrasound probe.

[0027] In one embodiment of the present invention, the front-end device 11 is a local device placed together with an ultrasonic probe and other devices in a preset ultrasonic detection space, so that the user can use the front-end device 11 to achieve the purpose of ultrasonic detection. The cloud imaging device 12 is a non-local device (such as a remote server or a cloud server) that places relevant functional modules in the "cloud". That is, the front-end device 11 and the cloud imaging device 12 are separated in physical space.

[0028] It should be understood that the ultrasonic probe mentioned above refers to a device that can be used to transmit an ultrasonic signal based on the ultrasonic control information determined by the front-end device 11 and receive an ultrasonic echo signal corresponding to the transmitted ultrasonic signal. In addition, there is a signal connection relationship between the ultrasonic probe and the front-end device 11.

[0029] In actual application, the front-end device 11 is first used to determine ultrasonic control information that can control the ultrasonic signal emitted by the ultrasonic probe. Then, the ultrasonic probe emits an ultrasonic signal to the target to be ultrasonically detected or the area to be ultrasonically detected based on the ultrasonic control information determined by the front-end device 11, and receives an ultrasonic echo signal corresponding to the emitted ultrasonic signal. The front-end device 11 generates an ultrasonic imaging signal that meets preset conditions based on the ultrasonic echo signal received by the ultrasonic probe, and sends the generated ultrasonic echo signal to the cloud imaging device 12. The cloud imaging device 12 generates ultrasonic image information based on the received ultrasonic imaging signal.

[0030] The ultrasound system provided by the embodiment of the present invention simplifies the structure of the front-end device by separating the front-end device and the cloud imaging device, and integrates the function of generating ultrasound image information based on ultrasound imaging signals into the cloud imaging device, thereby providing a prerequisite for miniaturization of the front-end device. In addition, the ultrasound system provided by the embodiment of the present invention facilitates the rapid upgrade and update of ultrasound imaging technology by integrating the function of generating ultrasound image information based on ultrasound imaging signals into the cloud imaging device.

[0031] It should be noted that the ultrasonic probe mentioned in the above embodiment may also be replaced by an ultrasonic emission and recovery module (not shown in the figure) provided in the front-end device 11, and the embodiment of the present invention does not make a unified limitation on this.

[0032] In one embodiment of the present invention, the signal connection between the front-end device 11 and the cloud imaging device 12 is implemented based on a network with a preset transmission speed, such as a network with a transmission speed greater than 125-128MB / s, so as to fully guarantee the real-time imaging function of the cloud imaging device 12.

[0033] In another embodiment of the present invention, the signal connection between the front-end device 11 and the cloud imaging device 12 is implemented based on the fifth generation mobile communication technology (5th Generation wireless systems, 5G) network. Since the 5G network has a high data transmission rate and can greatly reduce the transmission delay, the embodiment of the present invention can achieve the purpose of real-time imaging based on the cloud imaging device 12 by limiting the signal connection between the front-end device 11 and the cloud imaging device 12 to be implemented based on the 5G network. In addition, since the 5G network can support the communication connection of large-scale equipment (such as an ultrasound system including multiple front-end devices 11), the embodiment of the present invention can provide communication support for the subsequent expansion of the functional modules of the ultrasound system.

[0034] Figure 2 FIG. 1 is a schematic diagram of the structure of a cloud imaging device in an ultrasound system provided by an exemplary embodiment of the present invention. Figure 1 The present invention is extended based on the embodiment shown Figure 2 The embodiment shown is described below in detail. Figure 2 The embodiment shown and Figure 1 The differences and similarities of the illustrated embodiments are not described in detail.

[0035] In the ultrasound system provided in the embodiment of the present invention, the ultrasound probe includes a plurality of ultrasound channels. Figure 2 As shown, the cloud imaging device 12 includes a scheduling module 121, a data pre-processing module 122, an image reconstruction module 123 connected to the data pre-processing module 122 by signal, and an image post-processing module 124 connected to the image reconstruction module 123 by signal. In addition, the scheduling module 121 is connected to the data pre-processing module 122, the image reconstruction module 123, and the image post-processing module 124 by signal.

[0036] Specifically, the data pre-processing module 122 is used to perform a parallel demodulation processing operation on the ultrasonic imaging signal generated by the front-end device to generate demodulation information. The image reconstruction module 123 is used to perform a parallel image reconstruction operation based on the demodulation information to generate first ultrasonic image information. The image post-processing module 124 is used to perform an image post-processing operation on the first ultrasonic image information generated by the image reconstruction module 123 to generate second ultrasonic image information; the scheduling module 121 is used to manage the computing nodes in the cloud imaging device 12.

[0037] Exemplarily, the above-mentioned image post-processing operation includes at least one of a denoising operation, a registration operation and a recognition operation. Preferably, the denoising operation is implemented by a non-local means filtering algorithm; the registration operation is implemented by a piecewise rigid motion correction algorithm; and the recognition operation is implemented by a singular value decomposition algorithm.

[0038] Exemplarily, the data pre-processing module 122, the image reconstruction module 123 and the image post-processing module 124 are all implemented using a parallel computing algorithm designed based on a graphics processing unit (GPU).

[0039] It should be understood that in the embodiment of the present invention, since the ultrasound probe includes multiple ultrasound channels, the ultrasound imaging signal generated by the front-end device based on the ultrasound echo signal of the ultrasound probe is also multi-channel data.

[0040] Based on this, the embodiment of the present invention realizes the purpose of parallel processing of data to improve the data processing speed of the cloud imaging device 12 by means of the above-mentioned data pre-processing module 122 , image reconstruction module 123 and image post-processing module 124 .

[0041] In one embodiment of the present invention, the data pre-processing module 122, the image reconstruction module 123 and the image post-processing module 124 are all implemented using a modular design to provide extended embedded interfaces for different algorithms, thereby providing a guarantee for the rapid update operation of image reconstruction operations and image post-processing operations.

[0042] In one embodiment of the present invention, the scheduling module 121 adopts a database architecture to give full play to the cluster efficiency of the cloud imaging device 12, thereby improving the computational efficiency of image reconstruction and data processing. Preferably, the scheduling module 121 adopts a job scheduling framework based on Quartz.

[0043] It should be noted that in the above Figure 2 In the cloud imaging device 12 mentioned in the illustrated embodiment, not all modules are necessary. For example, the image post-processing module 124 may be deleted according to actual conditions, and the embodiment of the present invention does not impose a unified limitation on this.

[0044] Figure 3 FIG. 1 is a schematic diagram of the structure of a front-end device in an ultrasound system provided by an exemplary embodiment of the present invention. Figure 1 The present invention is extended based on the embodiment shown Figure 3 The embodiment shown is described below in detail. Figure 3 The embodiment shown and Figure 1 The differences and similarities of the illustrated embodiments are not described in detail.

[0045] like Figure 3 As shown, in the ultrasound system provided in the embodiment of the present invention, the front-end device 11 includes a beamforming module 111, an ultrasound radio frequency data acquisition module 112 signal-connected to the beamforming module 111, and a data compression module 113 signal-connected to the ultrasound radio frequency data acquisition module 112. In addition, the beamforming module 111 and the ultrasound radio frequency data acquisition module 112 are both signal-connected to the ultrasound probe.

[0046] Specifically, the beamforming module 111 is used to determine the ultrasound control information based on the cloud imaging device, and control the ultrasound signal emitted by the ultrasound probe based on the ultrasound control information. Exemplarily, the ultrasound control information is used to control the array element output of the ultrasound probe. For example, by applying an excitation signal with different time delays to each array element, the focusing and deflection of the ultrasound beam output by the probe array are controlled.

[0047] Since the ultrasound control information is determined based on the cloud imaging device, such as downloaded from the cloud imaging device, the embodiment of the present invention can greatly facilitate the upgrade and iteration operation of the ultrasound control information. In addition, when a cloud imaging device is connected to multiple front-end devices by signal, the unified upgrade and iteration operation of the ultrasound control information determined by the multiple front-end devices can also be implemented based on the cloud imaging device, thereby quickly realizing the standardized control of ultrasound imaging, breaking the situation where ultrasound equipment from different manufacturers cannot be managed uniformly, and facilitating the communication and sharing operation of clinical diagnosis.

[0048] In addition, the ultrasonic radio frequency data acquisition module 112 is used to convert the ultrasonic echo signal recovered by the ultrasonic probe into an ultrasonic imaging signal that meets the preset conditions. The data compression module 113 is used to perform parallel data compression operations on the ultrasonic imaging signal to better achieve the purpose of real-time imaging. It should be noted that the data compression module 113 in the embodiment of the present invention can reduce the pressure of data transmission, thereby ensuring the real-time imaging function of the ultrasonic system.

[0049] The ultrasound system mentioned in the embodiment of the present invention utilizes a beamforming module, an ultrasound radio frequency data acquisition module, and a data compression module, as well as the signal connection relationship between the modules, to form a front-end device for determining ultrasound control information that can control the ultrasound signal emitted by the ultrasound probe, and generating an ultrasound imaging signal that meets preset conditions based on the ultrasound echo signal corresponding to the ultrasound signal. The front-end device mentioned in the embodiment of the present invention realizes the above functions based on the above layout structure, and has many advantages such as reasonable layout, low cost, and strong practicality.

[0050] In one embodiment of the present invention, the ultrasonic probe includes a plurality of array elements, and the beamforming module 111 includes a dual-port random access memory (RAM), which is used to control the output information of the plurality of array elements so as to form the spatial directivity of the beam, thereby enabling the ultrasonic probe to emit a plane wave with a preset deflection angle. Specifically, the beamforming module 111 calculates the delay time of each array element based on the RAM and according to the preset deflection angle and records it in the RAM. According to the delay time of each array element, the pulse generator in the beamforming module 111 applies an excitation signal to the corresponding array element at different times, and the delay time of all array elements is linearly arranged with a preset deflection angle, thereby driving the array of array elements to emit a plane wave including a preset deflection angle.

[0051] Unlike existing focused beam imaging, which requires linear focusing scanning and then superimposing multiple scanning results to obtain a two-dimensional image, the embodiment of the present invention only needs to emit a plane wave once to excite the full-field signal to obtain a frame of two-dimensional image. Therefore, the embodiment of the present invention greatly improves the imaging speed and achieves the purpose of ultra-fast imaging.

[0052] It should be noted that in the above Figure 3 In the front-end device 11 mentioned in the illustrated embodiment, not all modules are necessary. For example, the data compression module 113 may be deleted according to actual conditions, and the embodiment of the present invention does not impose a unified limitation on this.

[0053] Figure 4 FIG. 1 is a schematic diagram of the structure of an ultrasound system provided by another exemplary embodiment of the present invention. Figures 1 to 3 The present invention is extended based on the embodiment shown Figure 4 The embodiment shown is described below in detail. Figure 4 The embodiment shown and Figures 1 to 3 The differences and similarities of the illustrated embodiments are not described in detail.

[0054] like Figure 4 As shown, the ultrasound system 10 provided in the embodiment of the present invention further includes an ultrasound display device 14 connected to the cloud imaging device 12 by signal. The ultrasound display device 14 includes a communication module 141 and an image display module 142 connected to the communication module 141 by signal.

[0055] Specifically, the communication module 141 is connected to the image post-processing module 124 of the cloud imaging device 12 by signal so as to transmit the second ultrasound image information generated by the image post-processing module 124 to the image display module 142. The image display module 142 is used to display the ultrasound image based on the received second ultrasound image information for the user to view.

[0056] Furthermore, in the embodiment of the present invention, the front-end device 11 further includes a data communication module 114, which is signal-connected to the data compression module 113 and the scheduling module 121 in the cloud imaging device 12. It should be understood that the data communication module 114 is used to establish a signal connection relationship between the front-end device 11 and the cloud imaging device 12, so as to transmit the ultrasound imaging signal generated by the front-end device 11 to the cloud imaging device 12.

[0057] Preferably, the signal connection between the ultrasonic probe 13 and the beamforming module 111 and the ultrasonic radio frequency data acquisition module 112 in the front-end device 11 is implemented based on a cable. That is, the signal connection between the ultrasonic probe 13 and the front-end device 11 is implemented based on a cable. When the ultrasonic probe 13 and the front-end device 11 are local devices placed together in a preset ultrasonic detection space, the signal connection between the two is limited to being implemented based on a cable, which can not only fully ensure the real-time and stability of data transmission, but also effectively reduce costs.

[0058] Preferably, the signal connection between the front-end device 11 and the cloud imaging device 12 is implemented based on a network with a preset transmission speed, and the signal connection between the cloud imaging device 12 and the ultrasound display device 14 is implemented based on a network with a preset transmission speed, so as to achieve the purpose of real-time ultrasound imaging display, for example, a 5G network implemented in a wireless manner.

[0059] It should be noted that the image display module 142 in the ultrasonic display device 14 can be a display device with a network connection function alone, or can be a display module of an existing ultrasonic diagnostic apparatus, and the embodiment of the present invention does not make a unified limitation on this.

[0060] The ultrasound system provided in the embodiment of the present invention utilizes an ultrasound probe, a front-end device, a cloud imaging device, and an ultrasound display device, as well as the signal connection relationship between the devices, to form an ultrasound system capable of realizing real-time ultrasound imaging with the aid of a cloud imaging device. The ultrasound system mentioned in the embodiment of the present invention not only realizes the lightweight of the front-end equipment (such as the ultrasound probe and the front-end device), which is convenient for users to use, but also provides conditions for the rapid upgrade and update of the post-processing equipment (such as the cloud imaging device).

[0061] In one embodiment of the present invention, the ultrasound probe includes a plurality of ultrasound channels, the data compression module 113 includes a plurality of compression units, and there is a one-to-one correspondence between the plurality of ultrasound channels and the plurality of compression units. Specifically, the ultrasound radio frequency data acquisition module 112 is connected to each of the plurality of ultrasound channels, and uses a multi-channel analog-to-digital conversion (A / D) to convert the original radio frequency analog signals corresponding to the plurality of ultrasound channels into parallel digital signals, and then transmits the converted parallel digital signals to the corresponding compression units respectively, and performs parallel data compression operations to reduce the amount of transmitted data.

[0062] Preferably, the ultrasonic radio frequency data acquisition module 112 is implemented based on a dual-input 7-13 bit incremental analog-to-digital converter from Cypress Semiconductor.

[0063] Preferably, the data compression module 113 is implemented using a Huffman coding compression algorithm.

[0064] Preferably, the data communication module 114 is implemented based on a wireless parallel gateway module. The parallel gateway module performs parallel data transmission and reception processing, and the data entering the gateway is divided into multiple channels according to the channels of the radio frequency data, so as to be wirelessly transmitted to the cloud imaging device 12.

[0065] In one embodiment of the present invention, the image reconstruction method adopted by the image reconstruction module 123 is a parallel delay and sum (DAS) method or a parallel frequency-wavenumber migration fK method.

[0066] Preferably, the image reconstruction module 123 uses the parallel frequency-wavenumber migration fk method to reconstruct the image. The specific calculation process is: let the x direction be the parallel direction of the ultrasonic transducer array, and the z direction be the depth direction of the imaging medium, so that ψ(x,z,t) is a scalar field that satisfies the linear wave equation. In fact, the signal collected by the ultrasonic probe is the surface wave field at z=0, that is, ψ(x,z=0,t). First, perform Fourier transform on ψ(x,z=0,t) in the (x,t) direction to obtain φ(k x ,ω). Then, using the dispersion relation Realized frequency ω and wave number k z The conversion of φ(k x ,k z Finally, for φ(k x ,k z ) is transformed by inverse Fourier transform to obtain ψ(x,z,t=0), which is the spatial intensity distribution of the imaging target at the initial moment, i.e., the reconstruction result.

[0067] In one embodiment of the present invention, in order to improve the image reconstruction quality and image reconstruction speed, a coherent superposition operation is performed on image results obtained at different deflection angles.

[0068] Specifically, for a point (x, z) in the imaging medium, a frame of image obtained by a single plane wave (deflection angle is α) is s(α, x, z). A series of different emission deflection angles α are selected. i (i=1,2,3…,N), for each specific deflection angle, an output image s(α i ,x,z), and then superimpose the N output images to get the final plane wave composite image:

[0069]

[0070] At this time, only one plane wave composite image I(x,z) can be obtained after N transmissions. In order to improve the reconstruction speed, the time sliding window mode is used to perform coherent plane wave composite at N angles, that is, the current frame obtained by each reconstruction is coherently composited with the previous N-1 frames at multiple angles, and the coherent composite of N angles is performed in sequence to obtain each frame of ultrasound image. With the time sequence, the deflection angle sequence of the transmission is {α1, α2, …α N ,α1,α2,…α N ,α1,α2,…α N ,…}, the corresponding output image is s j (α i ,x,z), and the time sliding window mode is adopted, then the plane wave composite image obtained at time t is the multi-angle coherent composite of the current output image and the previous N-1 frames, and the sliding window is performed, that is,

[0071]

[0072] The value of N is 4 to 32, and the selection of N depends on the requirements for image reconstruction quality and image reconstruction speed. It should be understood that the larger N is, the better the image reconstruction quality is, but the slower the image reconstruction speed is. Preferably, N is 9 to achieve a balance between image reconstruction quality and image reconstruction speed.

[0073] It should be noted that the algorithms embedded in the cloud imaging device 12 (such as image reconstruction algorithms, etc.) can be flexibly changed and set according to actual conditions to enrich image post-processing methods and thus form the above-mentioned distributed ultrasound imaging system.
