Detailed Description

The present application will be described in further detail with reference to the following detailed description and accompanying drawings. Wherein like elements in different embodiments are numbered with like associated elements. In the following description, numerous details are set forth in order to provide a better understanding of the present application. However, those skilled in the art will readily recognize that some of the features may be omitted or replaced with other elements, materials, methods in different instances. In some instances, certain operations related to the present application have not been shown or described in detail in order to avoid obscuring the core of the present application from excessive description, and it is not necessary for those skilled in the art to describe these operations in detail, so that they may be fully understood from the description in the specification and the general knowledge in the art.

Furthermore, the features, operations, or characteristics described in the specification may be combined in any suitable manner to form various embodiments. Also, the various steps or actions in the description of the methods may be transposed or transposed in order, as will be apparent to a person skilled in the art. Thus, the various sequences in the specification and drawings are for the purpose of describing certain embodiments only and are not intended to imply a required sequence unless otherwise indicated where such sequence must be followed.

The ordinal numbers used herein for the components, such as "first," "second," etc., are used merely to distinguish between the objects described, and do not have any sequential or technical meaning. The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings).

At present, since the mode such as Color, power, or doppler spectrum is originally information for providing blood flow, there are many disadvantages when applied to the ultrasound image mode of the interventional operation. The ultrasonic imaging in Color mode is taken as an example for explanation. As shown in fig. 1, the ultrasound imaging system alternately performs one frame of two-dimensional imaging scan and one frame of blood flow imaging scan, and then generates one frame of color doppler blood flow ultrasound image according to echo signals of the previous and subsequent one frame of two-dimensional imaging scan and one frame of blood imaging scan, for example, sequentially performs the 1 st frame of two-dimensional imaging scan, the 1 st frame of blood flow imaging scan, the 2 nd frame of two-dimensional imaging scan, the 2 nd frame of blood flow imaging scan, … …, the nth frame of two-dimensional imaging scan, the nth frame of blood flow imaging scan, … …; the 1 st frame two-dimensional imaging scan and the 1 st frame blood flow imaging scan are used for generating a color Doppler blood flow ultrasonic image of the 1 st frame, the 2 nd frame two-dimensional imaging scan and the 2 nd frame blood flow imaging scan are used for generating a color Doppler blood flow ultrasonic image of the 2 nd frame, … …, and the nth frame two-dimensional imaging scan and the nth frame blood flow imaging scan are used for generating a color Doppler blood flow ultrasonic image of the nth frame, … …. It can be seen that in the Color mode ultrasound imaging, the scanning and calculation of the blood flow imaging occupy a lot of resources, and if the blood flow imaging is applied to the ultrasound guidance image for guiding the doctor to perform the puncture intervention operation, the image frame rate is obviously reduced. Generally, in order to obtain better blood flow signals and richer blood flow information, the emission energy occupied by blood flow imaging can significantly exceed that of two-dimensional signals. The method is limited by regulations such as probe temperature rise, the energy which can be emitted in unit time has an upper limit, the blood flow imaging occupies much space, and the two-dimensional imaging needs to be reduced. Therefore, the signal-to-noise ratio of the two-dimensional signal is lost, and the direct expression is that the quality of the two-dimensional image is reduced, so that the display of tissues and puncture needles is influenced. In addition, the bleeding information is usually overlaid on the two-dimensional image in a pseudo-color form, 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, in which an ultrasound imaging system alternately performs one-frame blood flow imaging scan, continuous multi-frame two-dimensional imaging scan, for example, M-frame two-dimensional imaging scan, M being an integer greater than 1. Each frame of the blood flow imaging scan is used for determining the position of the blood vessel, and an ultrasonic image containing the position of the blood vessel is generated by each frame of the following multi-frame two-dimensional imaging scan. It can be seen that, because the time of the blood flow imaging scanning is greatly reduced, the resources occupied by the blood flow imaging scanning and calculation are also greatly reduced, so that the image frame rate is obviously increased, and the quality of the two-dimensional image is improved. Of course, the above concept can have various modifications, for example, one frame of blood flow imaging scan here can also be replaced by continuous multi-frame blood flow imaging scan, and as long as the number of frames of the continuous multi-frame blood flow imaging scan is ensured to be less than the number of continuous multi-frame two-dimensional imaging scans, the quality of the frame rate and the two-dimensional image of the ultrasound imaging in Color mode is still higher; for another example, since the blood flow imaging scan is used to determine the position of the blood vessel, the blood flow imaging scan may be replaced with other scan types that can be used to determine the position of the blood vessel; for another example, since the two-dimensional imaging scan is used to generate an ultrasound image of the internal tissue structure of the living body, the two-dimensional imaging scan may be replaced by other scan types capable of generating an ultrasound image of the internal tissue structure of the living body, and ultrasound images of other dimensions, such as three-dimensional and four-dimensional ultrasound images.

Fig. 3 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 transmit/receive control circuit 20, an echo processing unit 30, a processor 40, and a display unit 50.

The ultrasound probe 10 includes a plurality of elements for performing interconversion between electrical pulse signals and ultrasound waves, so as to transmit ultrasound waves to a biological tissue 60 to be detected (e.g., a biological tissue in a human or animal body) and receive ultrasound echoes reflected from the tissue. The plurality of array elements included in the ultrasonic probe 10 may be arranged in a row to form a linear array, or arranged in a two-dimensional matrix to form an area array, and the plurality of array elements may also form a convex array. The array element can emit ultrasonic waves according to the excitation electric signals or convert the received ultrasonic waves into electric signals. Each array element is thus operable to transmit ultrasound waves to biological tissue in the region of interest and also to receive ultrasound echoes returned through the tissue. When ultrasonic detection is carried out, which array elements are used for transmitting ultrasonic waves and which array elements are used for receiving the ultrasonic waves can be controlled through a transmitting sequence and a receiving sequence, or the time slots of the array elements are controlled to be used for transmitting the ultrasonic waves or receiving ultrasonic echoes. All array elements participating in ultrasonic wave transmission can be simultaneously excited by the electric signals, so that the ultrasonic waves are transmitted simultaneously; or the array elements participating in the ultrasonic wave transmission can be excited by a plurality of electric signals with certain time intervals, so that the ultrasonic waves with certain time intervals are continuously transmitted.

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

The echo processing unit 30 is configured to process the ultrasonic echo signal received by the ultrasonic probe 10, for example, filter, amplify, and perform beam forming 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, or may store data of the ultrasonic echo signal in a memory, and when an operation needs to be performed based on the ultrasonic echo data, the processor 40 reads the data of the ultrasonic echo signal from the memory. It will be appreciated by those skilled in the art that in some embodiments, the echo processing unit 30 may be omitted when it is not necessary to filter, amplify, beamform, etc. the ultrasound echo signals.

The processor 40 is used for acquiring the ultrasonic echo signals and obtaining the required parameters or images by adopting a relevant algorithm.

The display unit 50 may be used to display information, such as parameters and images calculated by the processor 40. It should be understood by those skilled in the art that in some embodiments, the ultrasound imaging system itself may not be integrated with the display unit, but may be connected to a computer device (e.g., a computer) to display information through the display unit (e.g., a display screen) of the computer device.

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

The transmission/reception control circuit 20 in one embodiment of the present application is configured to control the ultrasound probe 10 to execute a first scanning mode to scan a target tissue and receive an echo signal of the first scanning mode, and control the ultrasound probe 10 to execute a second scanning mode to scan the target tissue and receive an echo signal of the second scanning mode, where a number of scanning frames corresponding to the second scanning mode is greater than a number of scanning frames corresponding to the first scanning mode. In an embodiment, the number of the 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 for detecting the position of blood vessels in the target tissue, for example, the first scanning mode may be a C-scanning mode or a D-scanning mode, wherein the D-scanning mode may be a PW scanning mode, a CW scanning mode, or the like. The first scanning mode may use a conventional focusing method, a plane wave method, or the like. The second scan pattern here is an internal tissue structure for detecting the target tissue, for example the second scan pattern may be a B-scan pattern. The scanning ranges of the first scanning mode and the second scanning mode can be the same, so that the positions of blood vessels in the visible range of the ultrasonic image can be determined by a doctor, and omission is avoided.

The processor 40 determines the position of the blood vessel in the target tissue according to the echo signal of the first scanning mode, and generates a first ultrasound image corresponding to the target tissue according to the echo signal of the second scanning mode. The display unit 50 then displays the blood vessel position 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, which the transmission/reception control circuit 20 controls the ultrasound probe 10 to perform; in each scan round, the transmission/reception control circuit 20 controls the ultrasound probe 10 to perform a first scan mode to scan the target tissue and receive the echo signals of the first scan mode, and to perform the second scan mode to scan the target tissue and receive the echo signals of the second scan mode, and the processor 40 fuses the blood vessel positions determined from the echo signals of the first scan mode of the same round on the first ultrasound image generated from the echo signals of the second scan mode of the same round and displays them through the display unit 50. Specifically, for example, for each scan, the transmission/reception control circuit 20 counts the number of scan frames corresponding to the second scan pattern to determine whether the set number of frames is reached, and if the set number of frames is not reached, notifies the display unit 50 to display the blood vessel position on the first ultrasound image, and 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 the example of fig. 4, the ultrasound imaging system alternates between 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 round of the ultrasound imaging system includes a scan of the first scan pattern of N frames and a scan of the second scan pattern of M frames. As shown in fig. 5, taking the scanning of any one of the scanning rounds as an example, the blood vessel position is determined by scanning in a first scanning mode of N frames, the first ultrasound images of M frames are sequentially generated and displayed by scanning in a second scanning mode of M frames, and the blood vessel position determined by the scanning in the first scanning mode of N frames is displayed on the first ultrasound image when the first ultrasound image of each of the M frames is displayed. If the set frame number is set to M +1, the transmission/reception control circuit 20 counts the number of scanning frames corresponding to the second scanning mode to determine whether the set frame number M +1 is reached, and if the set frame number M +1 is not reached, the display unit 50 is notified to display the blood vessel position on the first ultrasound image, and 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 frame number will reach the M +1 th frame, and at this time, the transmission/reception control circuit 20 controls the ultrasound probe 10 to perform the next scanning round, instead of performing the scanning in the second scanning mode for the M +1 th frame.

According to the embodiment of the application, the position of the blood vessel is determined by the first scanning mode with relatively less scanning frame number, and the first ultrasonic image of the internal tissue structure of the target tissue is generated by the second scanning mode with relatively more scanning frame number, so that the frame rate and the quality of the finally displayed ultrasonic image can be effectively improved.

Further description of how the processor 40 determines the location of the blood vessel follows.

The processor 40 determines the position of the blood vessel in the target tissue according to the echo signals of the first scanning mode, and there may be various implementations, for example, one implementation may include: echo signals returned from the target tissue in the first scanning mode are received, blood flow signals are generated from the echo signals, and the positions of the blood vessels are determined according to the blood flow signals. The blood flow signal can be generated from the echo signal by using the current algorithm or a future algorithm, for example, taking the first scanning mode as the C scanning mode, the echo signal can be subjected to beam synthesis, orthogonal demodulation, filtering, autocorrelation calculation, velocity energy estimation and post-processing to generate the blood flow signal; the position with the blood flow signal can be judged to have a blood vessel; for example, taking the first scanning mode as the PW scanning mode, the PW signal intensity at each position may be calculated through the received echo signal, and whether there is a blood vessel is determined according to the PW signal intensity at each position, for example, a preset threshold is set, a position where the PW signal intensity is greater than the preset threshold is determined as having a blood vessel at the position, and a position where the PW signal intensity is less than the preset threshold is determined as having no blood vessel at the position.

After the processor 40 determines the blood vessel position, a target mask image may be generated according to the blood vessel position and fused on the first ultrasound image, and the display may display the blood vessel position on the first ultrasound image by displaying the fused image. For example, if there is a blood vessel position, the pixel value of the position in the mask image is set to a non-zero value, for example, 1, otherwise, if there is no blood vessel position, the pixel value of the position in the mask image is set to zero, so that the generated mask image is the target mask image described above through the whole frame of image. Since the number of frames of the first scan pattern may be one frame or multiple frames, how to specifically generate the target mask image will be described below based on these two cases.

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

In one embodiment, when the number of frames of the first scan pattern is multiple, such as N frames, where N is an integer greater than 1, the generating of the target mask image according to the blood vessel position by the processor 40 may include: generating N initial mask images according to the blood vessel positions corresponding to the N frames of scanning; and generating the target mask image according to the N initial mask images according to a preset mode, wherein the preset mode comprises at least one of a weighted addition mode and a maximum value mode.

Further explanation will be made below on how the blood vessel position is displayed on the first ultrasound image in detail.

The processor 40 may drive the display unit 50 to display the blood vessel position on the first ultrasound image. Specific modes can include various modes, and two modes are tried out below.

In a first mode, the blood vessel position is displayed on the first ultrasonic image in a pseudo-color mode, the blood vessel position can be rendered through a preset transparency in the pseudo-color mode, and a color value corresponding to the transparency is not limited. For example, referring to the example of fig. 7 (a), the position of the blood vessel is indicated by a semitransparent pseudo-color for the physician to view.

And secondly, displaying the position of the blood vessel on the first ultrasonic image in a boundary tracing mode, wherein the boundary tracing mode is used for tracing the boundary of the blood vessel through at least one line of a solid line and a broken line. For example, referring to the example of fig. 7 (b), the boundary of the blood vessel is depicted by a dashed line to illustrate the position of the blood vessel, so that the blood vessel can be viewed by the doctor.

The embodiment of the present application further provides a computer-readable storage medium, where multiple program instructions are stored, and after the multiple program instructions are called and executed by the processor 40, some or all of the steps or any combination of the steps in the method for displaying a blood vessel position in various embodiments of the present application may be executed.

In one embodiment, the computer readable storage medium may be a memory, which may be a non-volatile storage medium such as a flash memory card, solid state memory, hard disk, or the like.

In the embodiment of the present application, the processor 40 in the foregoing ultrasound imaging system may be implemented by software, hardware, firmware or a combination thereof, and may use a circuit, a single or multiple Application Specific Integrated Circuits (ASICs), a single or multiple general purpose integrated circuits, a single or multiple microprocessors, a single or multiple programmable logic devices, or a combination of the foregoing circuits or devices, or other suitable circuits or devices, so that the processor 40 may perform the corresponding steps of the blood vessel position display methods in the foregoing embodiments.

The application also provides a display method of the blood vessel position, which can be used for ultrasonic intervention guidance for a doctor to check the blood vessel position when entering intervention operations such as puncture and the like; referring to fig. 8, a method for displaying a blood vessel position according to an embodiment may include steps 110 to 150, which are described in detail below.

Step 110: a target tissue is scanned by a first scanning mode to determine a location of a blood vessel within the target tissue.

Referring to fig. 9, in an embodiment, the step 110 of scanning the target tissue through the first scanning mode to determine the position of the blood vessel in the target tissue may include steps 111 to 113.

Step 111: echo signals returned from the target tissue are received.

Step 112: a blood flow signal is generated from the echo signals.

And step 113: determining the vessel location from the blood flow signal.

Step 130: and scanning the target tissue through a second scanning mode to acquire a first ultrasonic image corresponding to the target tissue.

The number of scan frames corresponding to the second scan mode in step 130 is greater than the number of scan frames corresponding to the first scan mode in step 110.

In one embodiment the first scanning mode and the second scanning mode are different. The first scanning mode is used for detecting the position of blood vessels in the target tissue, for example, the first scanning mode may be a C-scanning mode or a D-scanning mode, wherein the D-scanning mode may be a PW scanning mode, a CW scanning mode, or the like. The first scanning mode may use a conventional focusing method, a plane wave method, or the like. The second scan pattern here is an internal tissue structure for detecting the target tissue, for example the second scan pattern may be a B-scan pattern. The scanning ranges of the first scanning mode and the second scanning mode can be the same, so that the positions of blood vessels in the visible range of the ultrasonic image can be determined by a doctor, and omission is avoided.

Step 150: displaying the vessel location on the first ultrasound image. In one embodiment, step 150 displaying the vessel location on the first ultrasound image includes at least one of:

in a second mode, the vessel position is displayed on the first ultrasound image in a manner of delineating a boundary of the vessel by at least one of a solid line and a dashed line.

Referring to fig. 10, the display method in an embodiment may further include an image fusion step 140; referring to fig. 11, the image fusion step 140 may include steps 141 and 142.

Step 141: a target mask image is generated from the determined vessel locations. The number of frames of the first scan pattern may be one frame or multiple frames, and how to generate the target mask image is described below based on these two cases. For example, when the number of scan frames corresponding to the first scan mode is 1, then generating the target mask image according to the blood vessel position may include: and obtaining an initial mask image according to the position of the blood vessel corresponding to the frame scanning, and determining the initial mask image as a target mask image. For example, when the number of scanning frames corresponding to the first scanning mode is multiple frames, for example, N frames, where N is an integer greater than 1, the generating the target mask image according to the blood vessel position may include: generating N initial mask images according to the blood vessel positions corresponding to the N frames of scanning; and generating the target mask image according to the N initial mask images according to a preset mode, wherein the preset mode comprises at least one of a weighted addition mode and a maximum value mode.

Step 142: the target mask image is fused on the first ultrasound image. Step 150 may then effect the display of the vessel location on the first ultrasound image by displaying the fused image.

The display method of an embodiment may include a plurality of scanning rounds, each scanning round including the step 110 of scanning the target tissue via a first scanning mode and the step 130 of scanning the target tissue via a second scanning mode; wherein the vessel position within the target tissue determined in the same scan round is displayed on the first ultrasound image acquired in the same scan round. In particular, when the method is implemented, the switching of each scanning round can be realized as follows: and counting the number of scanning frames corresponding to the second scanning mode to judge whether the number of the scanning frames reaches the set number of the scanning frames, if the number of the scanning frames does not reach the set number of the scanning frames, displaying the position of the blood vessel on the first ultrasonic image, and if the number of the scanning frames reaches the set number of the scanning frames, performing the next round of scanning. For example, the set frame number may be set to M +1, the scan frame number corresponding to the second scan mode is counted for each scan to determine whether the set frame number M +1 is reached, if the set frame number M +1 is not reached, the blood vessel position determined according to the current scan is displayed on the first ultrasound image generated according to the current scan, if the set frame number M +1 is reached, that is, if the next frame is to be scanned in the second scan mode, the frame number will reach the M +1 th frame, and then the next scan is performed at this time, instead of performing the scan in the second scan mode for the M +1 th frame.

This embodiment adds to the display of an interventional material, such as a puncture needle, on the basis of the above-described embodiment.

The transmission/reception control circuit 20 of an embodiment thus controls the ultrasound probe 10 to perform a third scanning mode for scanning the interventional material penetrated into the target tissue and to receive echo signals of the third scanning mode; the processor 40 generates a second ultrasound image corresponding to the interventional material according to the echo signal of the third scanning mode, and fuses the second ultrasound image and the first ultrasound image to be displayed in the display unit 50. Thus, as shown in fig. 12, the display unit 50 may display the blood vessel position and the intervention object in the ultrasound image. In an embodiment, the third scanning mode is different from the first scanning mode, and the third scanning mode may be the same as the second scanning mode.

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

Similarly, the display unit 50 displays the position of the blood vessel on the fused image of the first ultrasound image and the second ultrasound image, including at least one of the following ways:

and secondly, displaying the position of the blood vessel on the fused image of the first ultrasonic image and the second ultrasonic image in a boundary tracing mode, wherein the boundary tracing mode is used for tracing the boundary of the blood vessel through at least one line of a solid line and a broken line.

Therefore, for expansion, the display method of an embodiment, as shown in fig. 14, may include steps 210 to 270, which are described in detail below.

Step 210: a target tissue is scanned by a first scanning mode to determine a location of a blood vessel within the target tissue.

Step 230: and scanning the target tissue through a second scanning mode to acquire a first ultrasonic image corresponding to the target tissue.

The number of scan frames corresponding to the second scan mode in step 230 is greater than the number of scan frames corresponding to the first scan mode in step 210.

Step 250: and scanning the interventional object inserted into the target tissue through a third scanning mode to acquire a second ultrasonic image corresponding to the interventional object.
