S11, acquiring a target blood vessel and a plurality of longitudinal section images corresponding to the target blood vessel.

As mentioned above, the ultrasound probe of the ultrasound equipment is connected to the ultrasound probe through the ultrasound probe interface, and the medical personnel place the ultrasound probe on the target object to emit ultrasound and receive the ultrasound returned from the target object to obtain the ultrasound echo signal. Then the host computer processes the ultrasound echo signal into a Doppler ultrasound image containing the target object.

The medical staff can mark the target blood vessel from the ultrasound image according to the diagnosis requirement, and accordingly, the ultrasound equipment can obtain the target blood vessel.

After the target blood vessel is determined, the ultrasonic device can control the ultrasonic probe to rotate to image the target blood vessel in longitudinal section. The received ultrasonic echoes are sent to the host, and the host processes the ultrasonic echoes to obtain longitudinal section data of the target vessel, and then generate multiple longitudinal section images corresponding to the target vessel based on the longitudinal section data.

S12, identifying an optimal longitudinal section image from the plurality of longitudinal section images, and determining a probe position corresponding to the optimal longitudinal section image.

The optimal longitudinal section image is the longitudinal section image corresponding to the maximum vessel diameter of the target vessel. During the process of longitudinal section imaging, the ultrasonic equipment can compare the vessel diameter of the target vessel detected by it to obtain the maximum vessel diameter. Furthermore, the longitudinal section image corresponding to the maximum vessel diameter is saved as the optimal longitudinal section image.

After the optimal longitudinal section image is obtained, the ultrasound equipment identifies the optimal longitudinal section image to obtain the array element position data that generates the optimal longitudinal section image, and thus the probe position corresponding to the optimal longitudinal section image can be obtained .

S13, performing longitudinal section imaging on the target blood vessel based on the position of the probe.

The probe position is the optimal probe position for generating the optimal longitudinal section image. The ultrasound equipment can transmit ultrasound to the target blood vessel at this probe position for longitudinal section imaging. At the same time, the ultrasound equipment can receive the ultrasonic echo signal returned by the target blood vessel. In order to collect the optimal longitudinal section image in real time.

The blood vessel longitudinal section imaging method provided in this embodiment obtains multiple longitudinal section images corresponding to the target blood vessel, and identifies the optimal longitudinal section image corresponding to the target blood vessel from the multiple longitudinal section images, so as to determine the optimal longitudinal section image The position of the probe corresponding to the image, and then perform longitudinal section imaging of the target vessel based on the position of the probe, so as to realize real-time tracking and acquisition of the optimal longitudinal section of the target vessel. The medical staff can quickly obtain the optimal longitudinal section, which reduces the workload of the medical staff, improves the detection accuracy and detection efficiency of the optimal longitudinal section image, and effectively improves the diagnostic efficiency of the medical staff.

In this embodiment, a method for imaging a longitudinal section of a blood vessel is provided, which can be used in the above-mentioned ultrasonic equipment, such as a host computer. FIG. 4 is a flowchart of a method for imaging a longitudinal section of a blood vessel according to an embodiment of the present invention. As shown in FIG. The process includes the following steps:

S21. Acquire a target blood vessel and multiple longitudinal section images corresponding to the target blood vessel.

Specifically, the above step S21 may include:

S211. Acquire a cross-sectional image including at least one blood vessel.

The cross-sectional image is a two-dimensional ultrasound image obtained by emitting ultrasound from a single array of ultrasound probes. When the host computer of the ultrasound device does not receive an externally input longitudinal-section imaging command, the ultrasound device can send ultrasonic waves to the target object through a single array element to obtain a transverse-section ultrasound image of the blood vessel.

For example, the operation object places the ultrasonic probe according to the position of the blood vessel, the host controls the 0-array element of the ultrasonic probe to emit ultrasonic waves to the target object, and receives the ultrasonic waves returned from the target object to obtain ultrasonic echo signals, and the host computer controls the ultrasonic echo signals Process cross-sectional images of generated vessels.

S212, in response to the selection operation of the blood vessel by the operation object, determine a target blood vessel corresponding to the selection operation from at least one blood vessel.

The ultrasound equipment provides a blood vessel selection operation, and when the host computer obtains a cross-sectional image containing the target blood vessel, it can be displayed on the display interface of the host computer. The operation object (that is, the medical personnel) selects the target blood vessel from the blood vessels according to the diagnosis requirement thereof, and accordingly, the ultrasonic device can determine the target blood vessel in response to the selection operation of the operation object.

Specifically, the ultrasonic device can determine the target blood vessel according to the selection instruction input by the medical staff. For example, medical staff can move the cursor of the mouse to a blood vessel according to the prompt information in the display interface, and click to confirm that the selected blood vessel is the target blood vessel.

Optionally, the above step S212 may include:

(1) In response to a trigger operation of the target object for imaging the longitudinal section, at least one blood vessel corresponding to the trigger operation is acquired.

The triggering operation is triggered by the medical staff through an external input signal, and the medical staff can start the longitudinal section imaging operation of the blood vessel based on the external input signal. For example, a virtual button is preset on an interactive interface of the host display interface of the ultrasound equipment, or a virtual button is preset at a fixed position on the host display interface, or a physical button on the corresponding operation panel of the ultrasound equipment, or an external device (such as a foot switch, etc.), when the user clicks or presses the button, an external input signal is generated to start the longitudinal section imaging operation.

When starting the longitudinal section imaging operation, the ultrasound equipment controls the rotation of the ultrasound probe, and then obtains a longitudinal section image containing at least one blood vessel.

(2) In response to the selection operation of the blood vessel by the operation object, the target blood vessel corresponding to the selection operation is determined.

The operating object (that is, the medical staff) selects a certain blood vessel from the longitudinal section image as the target blood vessel. Correspondingly, the host of the ultrasound equipment can respond to the operating object's selection operation on the blood vessels contained in the longitudinal section image, and select a vessel from the longitudinal section image. A target blood vessel is determined from at least one blood vessel.

Optionally, the above method further includes: when only one blood vessel is included, determining the blood vessel as the target blood vessel.

The display interface of the main unit displays a longitudinal section image containing blood vessels. If the longitudinal section image contains only one blood vessel, the main unit of the ultrasonic equipment automatically recognizes the blood vessel and determines it as the target blood vessel.

S213. Obtain multiple longitudinal section images of the target blood vessel corresponding to the imaging operation in response to the imaging operation of the target blood vessel by the operating object.

After the target blood vessel is determined, the operating subject can perform an imaging operation on the target blood vessel. Correspondingly, the ultrasound device can respond to the imaging operation of the operating subject, perform corresponding imaging steps to obtain the imaging data of the target blood vessel, and obtain the longitudinal sliced image.

Here, the three imaging modes of matrix probe surface imaging, multi-array probe surface imaging and matrix probe volumetric imaging are taken as examples to illustrate as follows:

For surface imaging of the matrix probe, after receiving the imaging command input by the operating object, the ultrasonic device controls the ultrasonic probe to perform surface imaging of the target blood vessel, and multiple array elements of the ultrasonic probe emit ultrasonic waves to the target object at the same time, as shown in Figure 6 and receive the ultrasonic echo signal, as shown in Figure 7, and then obtain the three-dimensional data of the target blood vessel, so that the host can generate a longitudinal section image according to the three-dimensional data.

For surface imaging of multi-array probes, after receiving the imaging command input by the operating object, the ultrasonic device controls the ultrasonic probe to perform surface imaging of the target blood vessel, and multiple array elements of the ultrasonic probe emit ultrasonic waves to the target object at the same time, as shown in Figure 6 As shown in FIG. 9 , the ultrasonic echo signals are received, as shown in FIG. 9 , and image information corresponding to multiple arrays of target blood vessels is obtained.

For matrix probe volume imaging, after receiving the imaging command input by the operating object, the ultrasonic device controls the ultrasonic probe to scan the volume of the target blood vessel, and the motor drives the array to rotate according to the pre-configured speed and displacement to obtain the target blood vessel. 3D data, so that the host computer can generate longitudinal section images according to the 3D data, as shown in Figs. 6 and 10 .

S22, identifying an optimal longitudinal section image from the plurality of longitudinal section images, and determining a probe position corresponding to the optimal longitudinal section image. For details, refer to relevant descriptions corresponding to the foregoing embodiments, and details are not repeated here.

S23, performing longitudinal section imaging on the target blood vessel based on the position of the probe.

Specifically, the above step S23 may include:

S231. Obtain the target probe element corresponding to the probe position.

The target probe array element is the optimal probe array element that generates the optimal longitudinal section image. For different imaging modes, the determination methods of the target probe array elements are different.

Specifically, for matrix probe surface imaging, the ultrasound equipment can trace the boundary of the target blood vessel from the optimal longitudinal section image, and obtain the upper and lower walls of the target blood vessel, so that the position of each point on the upper wall of the target blood vessel can be obtained Information (A(a,b)), and then obtain the probe array element position (M(X,Y)) of each point, and then determine the probe position information combination corresponding to the optimal longitudinal section image. As shown in Figure 8, the ultrasonic equipment can determine that the combination of probe array elements corresponding to the optimal longitudinal section image is ((X2,Y1), (X3,Y2), (X4,Y3), (X5,Y4), (X6 ,Y5)). Optionally, after obtaining the upper and lower walls of the target blood vessel, select P points on the length of the target blood vessel, obtain the position information of the upper wall of each point, and then obtain the position of the probe element at each point, and finally obtain the most The combination of probe position information corresponding to the optimal longitudinal section.

For multi-array probe surface imaging, after the ultrasound equipment acquires the optimal longitudinal section image, it can directly acquire the position information corresponding to the optimal longitudinal section image. For example, m=7, a=4, it means that the ultrasonic probe contains 7 arrays, and the longitudinal section corresponding to the fourth array is the optimal longitudinal section, as shown in Figure 9, from which the probe corresponding to the optimal longitudinal section can be determined The position is in the fourth array.

For matrix probe volume imaging, the ultrasound equipment can trace the boundary of the target blood vessel from the optimal longitudinal section image, obtain the upper and lower walls of the target blood vessel, and then obtain the position information of each point on the upper wall of the blood vessel, and then obtain each The probe position information Xn of a point, where n is the displacement of the motor. As shown in FIG. 10, if n=2mm, the ultrasonic probe is moved and displaced by 2mm, and the probe position for generating the optimal longitudinal section image can be obtained.

S232, controlling the target probe array element to perform longitudinal section imaging of the target blood vessel.

Ultrasound equipment transmits ultrasonic waves to target blood vessels by controlling the acquired target probe array elements, so as to collect and track the optimal longitudinal section images in real time.

Specifically, for matrix probe surface imaging, after the ultrasonic equipment acquires the target probe array elements, for example, the target probe array elements are ((X2,Y1), (X3,Y2), (X4,Y3), (X5, Y4), (X6, Y5)), at this time, the ultrasound device can control the target probe array element to emit ultrasound to the target blood vessel, and then obtain the real-time optimal longitudinal section image.

Specifically, for multi-array probe surface imaging, after the ultrasound equipment acquires the array Xa composed of the target probe array elements, the ultrasound equipment can control the target probe array elements, and only use the probe array elements of the Xa array to transmit ultrasound to the target blood vessel. , and then obtain the real-time optimal longitudinal section image.

Specifically, for matrix probe volumetric imaging, after the ultrasound equipment obtains the displacement n of the target probe array element, the host computer of the ultrasound equipment can control the target probe array element, and after moving the target probe array element by n, the target blood vessel Ultrasound emission is performed to obtain real-time optimal longitudinal section images.

The blood vessel longitudinal section imaging method provided in this embodiment identifies at least one blood vessel included in the transverse section image, and selects the target blood vessel from it through the blood vessel selection function to perform longitudinal section images of multiple angles, thereby facilitating subsequent determination of the optimal blood vessel. Longitudinal section improves the efficiency of vascular imaging, thereby improving the diagnostic efficiency of medical staff. Based on the target probe array element corresponding to the probe position, only the target probe array element can be controlled to emit ultrasound to the target blood vessel, reducing the interference of longitudinal section imaging caused by unrelated probe array elements emitting ultrasound, and improving the accuracy of blood vessel longitudinal section imaging.

In this embodiment, a blood vessel longitudinal section imaging method is provided, which can be used in the above-mentioned ultrasonic equipment, such as a host computer. FIG. 5 is a flowchart of a blood vessel longitudinal section imaging method according to an embodiment of the present invention. As shown in FIG. 5 , the The process includes the following steps:

S31. Acquire a target blood vessel and multiple longitudinal section images corresponding to the target blood vessel. For details, refer to relevant descriptions corresponding to the foregoing embodiments, and details are not repeated here.

S32, identifying an optimal longitudinal section image from the plurality of longitudinal section images, and determining a probe position corresponding to the optimal longitudinal section image.

Specifically, the above step S32 may include:

S321. Generate guidance information of an optimal longitudinal section image.

The guidance information is used to represent the prompt information for generating the optimal longitudinal section image. During the process of performing the longitudinal section imaging of the target vessel by the ultrasound equipment, the guidance information of the optimal longitudinal section image can be generated and displayed on the display interface of the host computer. .

S322. In response to the scanning operation of the operating object on the guidance information, determine an optimal longitudinal section image corresponding to the scanning operation.

The operator can perform scanning operations according to the guidance information until the optimal longitudinal section image is found. Correspondingly, the ultrasound equipment can respond to the scanning operation corresponding to the operation to determine the maximum vessel diameter corresponding to the target vessel, and then obtain the maximum vessel diameter of the target vessel. Excellent longitudinal section images.

Specifically, the above step S322 may include:

(1) In response to the scanning operation of the operation object, determine a plurality of vessel diameters corresponding to the scanning operation.

The operation object sends scan instructions to the host to scan the target blood vessel in the target object. Correspondingly, the ultrasound equipment host can respond to the scan operation of the operation object to scan the target blood vessel in multiple directions, and obtain the target blood vessel corresponding to the target. Multiple vessel diameters of blood vessels.

Optionally, the above step (1) may include:

(11) Detecting the imaging mode corresponding to the scanning operation.

The imaging mode is the mode selected by the ultrasound equipment to perform longitudinal section imaging. Before performing longitudinal section imaging, the operation object can choose the ultrasound probe it is used to or the ultrasound probe supported by the ultrasound equipment, so that when performing longitudinal section imaging , the ultrasonic device can identify the ultrasonic probe used by the operating object, and then determine the imaging mode.

(12) Identify multiple boundaries of the target vessel corresponding to the imaging mode.

Different imaging modes correspond to different analysis methods, and the ultrasound equipment can sequentially extract the boundary corresponding to the target blood vessel from multiple longitudinal section images according to the imaging principle corresponding to the imaging mode.

(13) Based on multiple boundaries of the target blood vessel, calculate multiple vessel diameters corresponding to the target vessel.

According to the boundary of the target blood vessel extracted from the longitudinal section image, the blood vessel diameter of the target blood vessel can be calculated, that is, the distance between the upper boundary and the lower boundary of the target blood vessel. Thus, the ultrasonic device can obtain the vessel diameter of the target vessel in each longitudinal section image according to the vessel boundary extracted from each longitudinal section image.

(2) Determine the largest blood vessel diameter from the plurality of blood vessel diameters.

The ultrasound device compares the calculated multiple vessel diameters to determine the largest vessel diameter therefrom.

(3) Determine the longitudinal section image corresponding to the largest vessel diameter as the optimal longitudinal section image.

After determining the largest vessel diameter, the ultrasound equipment can determine the longitudinal section image corresponding to the largest vessel diameter, and the longitudinal section image is the optimal longitudinal section image.

Here, the three imaging modes of matrix probe surface imaging, multi-array probe surface imaging and matrix probe volumetric imaging are described.

For matrix probe imaging, the ultrasound equipment can directly obtain the maximum slice of the target blood vessel according to the imaging principle of matrix probe imaging. Similarly, the ultrasonic equipment can also analyze the acquired three-dimensional data to find the optimal longitudinal section image, that is, the ultrasonic equipment can extract the boundary of the target blood vessel through the three-dimensional data, and then obtain the optimal longitudinal section of the target blood vessel according to the principle of the largest diameter image.

Specifically, the ultrasound equipment can first trace the boundary of the target blood vessel, and obtain the upper and lower walls of the target blood vessel, so that the position information of each point on the upper wall of the target blood vessel can be obtained, and then the probe array element of each point can be obtained position(M(X,Y)). As shown in Figure 8, if the probe element combination corresponding to the largest vessel diameter is ((X2,Y1), (X3,Y2), (X4,Y3), (X5,Y4), (X6,Y5)), Then the longitudinal section image generated by the probe array element combination is the optimal longitudinal section image.

For multi-array probe surface imaging, the ultrasound equipment recognizes the acquired longitudinal section images of multiple arrays, obtains the average vessel diameter D of each longitudinal section image, and then compares the m vessel diameters to obtain the vessel diameter The largest longitudinal section image is taken as the optimal longitudinal section image, where m is the number of image arrays.

Specifically, after the ultrasound equipment acquires multiple array images, it processes each pair of images, such as processing the X1 image, taking the center point of the blood vessel as the center, M cm in a certain area as the blood vessel wall, and taking N points to calculate the blood vessel diameter, to obtain the average vessel diameter D. If the center point 1cm of the target blood vessel is taken in the longitudinal section image area, and 5 points are taken to calculate the average diameter, then D=(D1+D2+D3+D4+D5)/5, as shown in FIG. 8 . The values of M and N can be configured by medical personnel according to actual conditions. For example, if the medical personnel set M=2, N=3, it means that the area 2cm away from the centerline of the target blood vessel is taken as the vessel wall, and three points (the midpoint, one point at 2cm left and right) are taken to calculate the vessel diameter. Correspondingly, on the X2 image, the diameter of the blood vessel obtained by the same method is D2, and the diameter obtained on the m images is Dm. Compare the sizes of the m diameters, find the longitudinal section image with the largest diameter of the blood vessel, and use it as the optimal longitudinal section image. For example, when m=7 and a=4, it means that the ultrasonic probe has 7 arrays, and the longitudinal section image corresponding to the fourth array is the optimal longitudinal section image.

For matrix probe volume imaging, the ultrasound equipment analyzes the acquired three-dimensional data, extracts the boundary of the target blood vessel, and then obtains the optimal longitudinal section image of the target blood vessel according to the principle of maximum diameter. Specifically, the ultrasonic device can first trace the boundary of the target blood vessel, obtain the upper and lower walls of the target blood vessel, and then obtain the position information of each point on the upper wall of the target blood vessel, and then obtain the probe position information Xn, where n is the displacement of the motor . As shown in FIG. 10, if n=2mm, it means that when the displacement of the probe is 2mm, the longitudinal section image obtained is the optimal longitudinal section image.

S323. Based on the position information of the optimal longitudinal section image, determine the position of the probe for generating the optimal longitudinal section image.

The position information of the optimal longitudinal section image is the position of the boundary of the blood vessel in the optimal longitudinal section image, that is, the upper wall of the blood vessel and the lower wall of the blood vessel. When the ultrasound equipment obtains the position information of the optimal longitudinal section image, it can determine the position of the probe array element corresponding to the position information, thereby determining the combination of probe array elements for generating the optimal longitudinal section image, that is, the position of the probe.
