detailed description

The present application will be further described in detail below through specific embodiments in combination with the accompanying drawings. In the different embodiments, similar elements are labeled with associated similar elements. In the following embodiments, many details are described so that the present application can be better understood. However, those skilled in the art can effortlessly realize that some of these features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to this application are not shown or described in the description. This is to prevent the core part of this application from being overwhelmed by excessive descriptions. For those skilled in the art, these are described in detail. The related operations are not necessary, they can fully understand the related operations according to the description in the description and the general technical knowledge in the field.

In addition, the features, operations, or features described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can also be sequentially swapped or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the description and drawings are only for clearly describing a certain embodiment, and are not meant to be a necessary order, unless otherwise stated that a certain order must be followed.

The serial numbers of components in this article, such as "first", "second", etc., are only used to distinguish the described objects and do not have any order or technical meaning. The terms “connection” and “connection” in this application include direct and indirect connections (connections) unless otherwise specified.

At present, since the modes such as Color, Power, or Doppler spectrum are originally used to provide information on blood flow, there are many disadvantages when applied to ultrasound image modes for interventional operations. Take the ultrasound imaging in Color mode as an example. As shown in Figure 1, the ultrasound imaging system alternately performs one frame of two-dimensional imaging scans and one frame of blood flow imaging scans, and then generates one frame of color based on the echo signals of one frame of two-dimensional imaging scans and one frame of blood imaging scans before and after. Doppler blood flow ultrasound images, for example, sequentially perform the first two-dimensional imaging scan, the first frame blood imaging scan, the second frame two-dimensional imaging scan, the second frame blood imaging scan, ..., the n frame two -Dimensional imaging scan, n-th frame blood flow imaging scan, ...; the first two-dimensional imaging scan and the first frame blood flow imaging scan are used to generate a color Doppler blood flow ultrasound image of the first frame, the second frame of the second The two-dimensional imaging scan and the second frame blood flow imaging scan are used to generate the color Doppler blood flow ultrasound image of the second frame, ..., the nth two-dimensional imaging scan and the nth frame blood flow imaging scan are used to generate the nth frame. Frame color Doppler ultrasound images, ... It can be seen that in the ultrasound imaging in Color mode, the scanning and calculation of blood flow imaging will occupy a lot of resources. If it is used in the ultrasound guided image used to guide the doctor to perform the puncture intervention operation, the image frame rate will be significantly reduced. Generally, in order to obtain better blood flow signals and richer blood flow information, the emission energy occupied by blood flow imaging will obviously exceed the two-dimensional signal. Subject to regulations such as probe temperature rise, there is an upper limit to the amount of energy that can be emitted per unit time. Blood flow imaging takes up more, and two-dimensional imaging must be reduced. Therefore, the signal-to-noise ratio of the two-dimensional signal will be lost, and the direct expression is that the quality of the two-dimensional image is reduced, which affects the display of the tissue and the puncture needle. In addition, the bleeding information is usually overlaid on the two-dimensional image in the form of false colors, so that the doctor cannot view the two-dimensional image of the current position.

To solve the above problem, the present application provides an exemplary concept as shown in FIG. 2. The ultrasound imaging system alternately performs one frame of blood flow imaging scan and continuous multi-frame two-dimensional imaging scan, such as M-frame two-dimensional imaging scan, where M is greater than An integer of 1. Each frame of the blood flow imaging scan is used to determine the position of the blood vessel, and an ultrasound image containing the position of the blood vessel is generated in sequence with each frame of the subsequent multi-frame two-dimensional imaging scan. It can be seen that because the time of the blood flow imaging scan is greatly reduced, the resources occupied by the blood flow imaging scan and calculation are also greatly reduced, which significantly increases the image frame rate and improves the quality of the two-dimensional image. Of course, the above concept can be modified in various ways. For example, one frame of blood flow imaging scan can be replaced by a continuous multi-frame blood flow imaging scan, as long as the number of frames of this continuous multi-frame blood flow imaging scan is less than continuous The number of multi-frame 2D imaging scans is still higher than the image frame rate and 2D image quality of Color mode ultrasound imaging; for example, because blood flow imaging scans are used to determine the position of blood vessels, blood flow imaging here Scans can be replaced with other scan types that can be used to determine the location of blood vessels; for example, since the two-dimensional imaging scan here is used to generate ultrasound images of the internal tissue structure of a living body, the two-dimensional imaging scan here can also be replaced with another Scan types that can generate ultrasound images of the internal tissue structure of a living body, as well as ultrasound images of other dimensions, such as three-dimensional, four-dimensional ultrasound images.

Please refer to FIG. 3, which is a schematic structural diagram of an ultrasound imaging system according to an embodiment. The ultrasound imaging system may include an ultrasound probe 10, a transmission / reception control circuit 20, an echo processing unit 30, a processor 40, and a display unit 50.

The ultrasound probe 10 includes a plurality of array elements, which are used to realize the mutual conversion of electric pulse signals and ultrasound waves, thereby realizing the transmission of ultrasound waves to the detected biological tissue 60 (such as biological tissue in a human body or an animal body) and receiving ultrasonic waves reflected by the tissue. wave. The plurality of array elements included in the ultrasound probe 10 may be arranged in a row to form a linear array, or arranged in a two-dimensional matrix to form a surface array, and the plurality of array elements may also constitute a convex array. The array element can transmit ultrasonic waves according to the excitation electric signal, or transform the received ultrasonic waves into electric signals. Therefore, each array element can be used to transmit ultrasonic waves to biological tissues in the region of interest, and can also be used to receive ultrasonic echoes returned by the tissue. When performing ultrasonic detection, it is possible to control which array elements are used to transmit ultrasonic waves, which array elements are used to receive ultrasonic waves, or to control the array elements to be used to transmit ultrasonic waves or receive ultrasonic echoes by transmitting and receiving sequences. All array elements participating in ultrasonic emission can be simultaneously excited by electrical signals, thereby transmitting ultrasonic waves simultaneously; or the array elements participating in ultrasonic emission can also be excited by several electrical signals with a certain time interval, thereby continuously transmitting ultrasonic waves with a certain time interval.

The transmitting / receiving control circuit 20 is used to control the ultrasonic probe 10 to transmit an ultrasonic beam to the biological tissue 60 on the one hand, and to control the ultrasonic probe 10 to receive the ultrasonic echo reflected by the ultrasonic beam through the tissue. In a specific embodiment, the transmitting / receiving control circuit 20 is configured to generate a transmitting sequence and a receiving sequence, and output them to an ultrasound probe. The transmission sequence is used to control some or all of the plurality of array elements in the ultrasound probe 10 to transmit ultrasonic waves to the target of interest in the biological tissue 60. The parameters of the transmission sequence include the number of array elements for transmission and ultrasonic transmission parameters (e.g., amplitude, frequency, Number of waves, transmission interval, transmission angle, wave pattern and / or focus position, etc.). The receiving sequence is used to control some or all of the plurality of array elements to receive the echoes after the ultrasound is organized. The parameters of the receiving sequence include the number of array elements for receiving and the receiving parameters of the echo (such as the receiving angle, depth, etc.). Depending on the application of the ultrasound echo or the images generated based on the ultrasound echo, the ultrasound parameters in the transmitting sequence and the echo parameters in the receiving sequence are different.

The echo processing unit 30 is configured to process an ultrasonic echo signal received by the ultrasound probe 10, for example, perform processing such as filtering, amplification, beam synthesis, and the like on the ultrasonic echo signal to obtain a processed ultrasonic echo signal. In a specific embodiment, the echo processing unit 30 may output the processed ultrasonic echo signal to the processor 40, and may also store the data of the ultrasonic echo signal in a memory first, and perform the processing based on the ultrasonic echo data. During the calculation, the processor 40 reads the data of the ultrasonic echo signal from the memory. Those skilled in the art should understand that in some embodiments, the echo processing unit 30 may be omitted when it is not necessary to perform processing such as filtering, amplifying, and beam combining the ultrasonic echo signals.

The processor 40 is configured to obtain an ultrasonic echo signal, and obtain a required parameter or image by using a related algorithm.

The display unit 50 may be used for displaying information, such as displaying parameters and images calculated by the processor 40. Those skilled in the art should understand that in some embodiments, the ultrasound imaging system itself may not integrate a display unit, but may be connected to a computer device (for example, a computer) and display information through the display unit (for example, a display screen) of the computer device.

The above is a basic structure of an ultrasound imaging system.

In an embodiment of the present application, the transmitting / receiving control circuit 20 is configured to control the ultrasound probe 10 to perform a first scanning mode to scan a target tissue and receive an echo signal in the first scanning mode, and to control the ultrasound probe 10 to perform a second scanning mode. The target tissue performs scanning and receives echo signals in a second scanning mode, where the number of scanning frames corresponding to the second scanning mode is greater than the number of scanning frames corresponding to the first scanning mode. In one embodiment, the number of scanning frames corresponding to the first scanning mode may be one frame or multiple frames. In one embodiment, the first scanning mode and the second scanning mode are different. The first scanning mode is used to detect the position of a blood vessel in the target tissue. For example, the first scanning mode may be a C scanning mode or a D scanning mode, and the D scanning mode may be a PW scanning mode or a CW scanning mode. The first scanning mode may use a conventional focusing method, a plane wave method, or the like. The second scanning mode is used to detect the internal tissue structure of the target tissue. For example, the second scanning mode may be a B-scan mode. The scanning ranges of the first scanning mode and the second scanning mode can be the same, so that the position of the blood vessels in the visible range of the doctor on the ultrasound image can be determined sufficiently, and no omission will occur.

The processor 40 determines the position of the blood vessel in the target tissue according to the echo signal in the first scanning mode, and generates a first ultrasound image corresponding to the target tissue according to the echo signal in the second scanning mode. The display unit 50 displays the position of the blood vessel on the first ultrasound image.

As shown in FIG. 4, the ultrasound imaging system of an embodiment may include one or more rounds of scanning. The transmitting / receiving control circuit 20 controls the ultrasound probe 10 to perform the multiple rounds of scanning. In each round of scanning, the transmitting / receiving control circuit Both control the ultrasound probe 10 to execute the first scanning mode to scan the target tissue and receive the echo signal of the first scanning mode, and execute the second scanning mode to scan the target tissue and receive the echo signal of the second scanning mode The processor 40 fuses the blood vessel position determined according to the echo signal of the first scan mode in the same round to the first ultrasound image generated according to the echo signal of the second scan mode in the same round, and passes the display unit 50 To show. Specifically, for example, for each round of scanning, the transmitting / receiving control circuit 20 counts the number of scanning frames corresponding to the second scanning mode to determine whether the set number of frames is reached. If the set number of frames is not reached, the display unit 50 is notified to The blood vessel position is displayed on the first ultrasound image. If the set number of frames is reached, the transmission / reception control circuit 20 controls the ultrasound probe 10 to perform the next scan. Taking FIG. 4 as an example, the ultrasound imaging system alternately performs scanning in a first scanning mode of N frames and scanning in a second mode of M frames, where N and M are both positive integers and M is greater than N. In other words, each scan of the ultrasound imaging system includes a scan in a first scan mode of N frames and a scan in a second scan mode of M frames. As shown in FIG. 5, taking any one of the scans as an example, the position of a blood vessel is determined by scanning in the first scanning mode of N frames, and the scanning of the second scanning mode in M frames is used to sequentially generate and display the first An ultrasound image displays the position of the blood vessel determined by the scanning in the first scanning mode of the N frames on the first ultrasound image when the first ultrasound image in each of the M frames is displayed. The above-mentioned set frame number can be set to M + 1, then the transmission / reception control circuit 20 counts the number of scan frames corresponding to the second scan mode to determine whether the set frame number M + 1 is reached, and if the set frame number is not reached If the number is M + 1, the display unit 50 is notified to display the position of the blood vessel on the first ultrasound image. If the set frame number M + 1 is reached, that is, if the next frame is to be scanned in the second scanning mode, the number of frames will be The M + 1 frame will be reached, then the transmit / receive control circuit 20 controls the ultrasound probe 10 to perform the next scan instead of the second scan mode scan of the M + 1 frame.

In the embodiment of the present application, the position of a blood vessel is determined by a first scan mode with a relatively small number of scanning frames, and a first ultrasound image of the internal tissue structure of the target tissue is generated by a second scan mode with a relatively large number of scanned frames, which can effectively Improve the frame rate and quality of the final ultrasound image displayed.

How the processor 40 determines the position of the blood vessel is further described below.

The processor 40 determines the position of the blood vessel in the target tissue according to the echo signal in the first scanning mode. There may be multiple implementations. For example, one of the implementations may include receiving an echo returned from the target tissue in the first scanning mode. A signal, and a blood flow signal is generated from the echo signal, and the blood vessel position is determined according to the blood flow signal. The blood flow signal can be generated from the echo signal using the current algorithm or the algorithm that will appear in the future. For example, taking the first scanning mode as the C scanning mode, the echo signal can be beam-synthesized, orthogonally demodulated, Filtering, autocorrelation calculation, velocity energy estimation, and post-processing to generate blood flow signals; where there is a blood flow signal, it can be determined that there is a blood vessel at that position; for example, if the first scan mode is the PW scan mode, you can Calculate the PW signal strength of each location based on the received echo signals, and determine whether there is a blood vessel based on the PW signal strength of each location. For example, a preset threshold is set. A location with a PW signal strength greater than a preset threshold is determined as There is a blood vessel at this position, and a position where the PW signal strength is less than a preset threshold determines that there is no blood vessel at the position.

After the processor 40 determines the position of the blood vessel, it can generate a target mask image according to the position of the blood vessel, and fuse the target mask image on the first ultrasound image. The display can display the position of the blood vessel by displaying the fused image. First ultrasound image. For example, if there is a blood vessel, set the pixel value at that position in the mask image to a non-zero value, such as 1, otherwise, if there is no blood vessel position, set the pixel value at that position in the mask image to zero, and traverse For the entire frame image, the generated mask image is the aforementioned target mask image. Since the number of frames in the first scanning mode can be one frame or multiple frames, the following describes how to specifically generate a target mask image according to these two situations.

In an embodiment, when the number of scanning frames corresponding to the first scanning mode is 1, the processor 40 generating the target mask image according to the blood vessel position may include: obtaining an initial mask image according to the blood vessel position corresponding to this frame scanning, This initial mask image is determined as the target mask image.

In an embodiment, when the number of scanning frames corresponding to the first scanning mode is multiple frames, for example, N frames, and N is an integer greater than 1, the processor 40 generating the target mask image according to the position of the blood vessel may include: scanning according to the N frames N initial mask images are generated at corresponding blood vessel positions; the N initial mask images are used to generate the target mask image in a preset manner, where the preset manner includes a weighted addition method and a maximum value At least one of the ways. Please refer to FIG. 6. It may be possible to take two frames as an example. Two initial mask images are generated at the corresponding blood vessel positions in the two scans of the first scan mode.
