Description

Technical Field

[0001] The present invention relates to the field of Doppler imaging technology, and in particular to a method and device for realizing a multi-modal holographic spectrum of medical ultrasonic equipment. Background Art

[0002] In medical color Doppler ultrasound equipment systems, pulse Doppler technology is a relatively common imaging technology. As described in patent 202010225632.3, a general method for realizing Doppler spectrum D images is to emit ultrasound to a sampling window at a certain position and then detect the phase or frequency changes in the echo, so that the blood flow distribution and hemodynamic characteristics of the organs at the sampling window can be observed in real time, thereby providing great convenience for doctors' diagnosis.

[0003] The current general Doppler imaging method can provide a sampling window or multiple windows in any specific one-dimensional, two-dimensional section or three-dimensional volume data in real time, which is relatively convenient for measuring the velocity or direction of blood flow, tissue, or measuring the velocity or direction of multiple tissues or blood flow at the same time. Patent CN201510574474.1 describes that by generating a wide beam through multiple transmissions and receiving different signals at different positions at the same time, Doppler spectra at different positions can be obtained. Patent 202011287567.3 mainly describes a vector blood flow Doppler imaging method, which not only detects the magnitude of the velocity, but also detects the direction of blood flow movement; Patent CN201910916443.8 describes the problem of precise positioning of the regurgitation spectrum in the cardiac mode of the phased array probe, using the emission of ultrasonic waves, receiving multiple multi-angle receiving lines, and synthesizing the Doppler information at the sampling gate through multiple multi-angle lines; Patent CN202010609264.2 describes the use of sampling gates with different deflection angles for spectral imaging, pre-setting multiple sampling gates, emitting ultrasonic waves at different angles multiple times, and receiving ultrasonic waves at different angles multiple times.

[0004] The above-mentioned domestic manufacturers have preliminarily solved the problem of measuring blood flow velocity at multiple points at the same time, but there are several defects. First, the beam width cannot cover all areas covered by the probe, the emitted ultrasonic signal is weak, and the signal-to-noise ratio of the spectrum will be reduced; second, it is impossible to display multiple feature images at the same time, such as real-time display of conventional B, C, and multi-point D three-modal images. It is not easy to locate when tissue and blood flow move at the same time, and it is easy to misjudge; third, generally, multi-sampling gates are basically implemented under linear array probes, that is, multi-sampling gate spectrum images are realized at high PRF (pulse repetition frequency). Because the PRF is low, it is basically unusable on low-frequency probes.

[0005] Therefore, the present invention provides a method and device for realizing a multi-modal holographic spectrum of a medical ultrasound device. Summary of the invention

[0061] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0062] Example 1

[0063] This embodiment provides a method and device for realizing multi-modal holographic spectrum of medical ultrasound equipment, such as Figure 1 As shown, including:

[0064] Step 1: transmitting a short pulse waveform to an examination part of a patient to obtain a first image of the patient, transmitting N groups of long pulse waveforms with preset deflection angles to the examination part to obtain N frames of plane wave images of the patient;

[0065] Step 2: Divide each of the plane wave images into a plurality of sub-image frames, and perform weighted processing on each sub-image frame according to the preset deflection angle to obtain the key information area of ​​the patient;

[0066] Step 3: Acquire spectrum data of the key information area, draw a corresponding spectrum image according to the spectrum data, and use the first image to fill the spectrum image with data to obtain a second image of the patient;

[0067] Step 4: Perform foreground extraction on the second image to obtain a blood flow signal of the patient, generate a third image of the patient based on the blood flow signal, and display the third image.

[0068] In this example, a short pulse waveform is emitted first, and then N groups of long pulse waveforms with different angles are emitted simultaneously;

[0069] In this example, the key information area indicates the area where the inspection part is located;

[0070] In this example, the third image is a three-dimensional color image;

[0071] In this example, the patent adopts a plane wave transmission and reception method, which can set the number of sampling windows without limit and can display them in real time. In addition, due to the high frame rate full-area scanning coverage, the speed, direction, and frequency spectrum of each point of blood flow can be accurately obtained.

[0072] The working principle and beneficial effects of the above technical solution: In the medical color ultrasound system, the most commonly used method for doctors to diagnose is through the speed of blood flow or tissue. The key to calculating the speed of blood flow or tissue movement is that the user can arbitrarily select sampling windows at different positions and can accurately display the blood flow, tissue speed and direction information of multiple sampling windows in real time. In order to facilitate doctors to diagnose patients, first a group of short pulse waveforms are emitted to the examination part of the patient to collect the first image, and then N groups of long pulse waveforms with different angles are emitted to obtain N frames of plane wave images of the patient. By performing a series of processing on the first image and the plane wave image, the patient's blood flow signal can be determined, thereby generating a three-dimensional, colorful three-dimensional image for doctors to diagnose. Multiple examination parts can be scanned at one time, and the patient's tissue and blood flow can be quickly located, thereby improving the doctor's judgment ability, enhancing the doctor's diagnosis and treatment effect, and providing better medical services for patients.

[0073] Example 2

[0074] On the basis of Example 1, the method for realizing a multi-modal holographic spectrum of a medical ultrasound device, wherein step 1 comprises:

[0075] Step 11: transmitting a short pulse waveform to the examination part of the patient to obtain a first echo signal of the patient, and drawing a first image according to the first echo signal;

[0076] Step 12: Analyze the integrity of the first image. When the first image meets the specified integrity standard, transmit N groups of long pulse waveforms with preset deflection angles to the examination part, obtain the second echo signal of the patient for each group of the long pulse waveforms, and draw the plane wave image of the patient according to the second echo signal.

[0077] In this example, the integrity standard is specified as follows: the blank rate in the image is no higher than 2%.

[0078] The working principle and beneficial effects of the above technical solution are as follows: when examining a patient, a short pulse waveform is first emitted to the examination part to obtain a first image. When the first image is qualified, a second scan is performed to obtain a plane wave image of the patient. In this way, the examination part of the patient can be examined multiple times and at multiple angles in a short period of time to obtain more effective and clearer images, which is convenient for doctors to diagnose.

[0079] Example 3

[0080] On the basis of Example 1, the method for realizing a multi-modal holographic spectrum of a medical ultrasound device, the step 2 comprises:

[0081] Step 21: Divide each of the plane wave images into a plurality of frame sub-images of a specified specification, and according to the distribution structure of the sub-images in the plane wave image, the sub-images having the same description content are regarded as the same image class according to the distribution structure and the preset deflection angle;

[0082] Step 22: spatially arranging each of the image classes according to the preset deflection angle to generate a first sub-image set, identifying the deflection angle corresponding to each of the sub-images in the first sub-image set, and weighting the overlapping areas contained in each of the sub-images according to the deflection angle to obtain a plurality of frames of second sub-images;

[0083] Step 23: extracting corresponding key areas in each of the second sub-images according to the area of ​​interest selected by the user, identifying associated areas corresponding to the key areas in each of the second sub-images, determining and displaying the key information areas corresponding to the patient.

[0084] In this example, the specified size is 9*9 pixels;

[0085] In this example, the distribution structure refers to the structure formed by arranging the sub-images in the plane wave image;

[0086] In this example, having the same description content means that: a feature of the same inspection part is expressed in multiple frame sub-images from different plane wave images;

[0087] In this example, the process of spatial arrangement is: arrange the images in three-dimensional space according to the angle corresponding to each sub-image. For example, sub-image A captures the front of an organ, and sub-image B captures the right side of an organ. Since the shooting angle between sub-image A and sub-image B is 90°, sub-image A and sub-image B are arranged at corresponding angles during spatial arrangement.

[0088] In this example, the user is a doctor.

[0089] The working principle and beneficial effects of the above technical solution: In order to further analyze the patient's examination situation, each plane wave image is first divided into several sub-images, and the sub-images are classified according to the preset deflection angle and sub-image distribution structure. Then, the sub-images of the same type are spatially arranged to generate a first sub-image set. The overlapping areas in the sub-images are further weighted according to the deflection angle to achieve the purpose of image enhancement and obtain the second sub-image. Finally, according to the instructions issued by the doctor, the area of ​​interest is expanded and identified, and the patient's key information area is determined. In this way, the patient's examination area can be scanned in detail, and all the detailed morphology of the identified area can be displayed with the help of multiple angles, which is convenient for doctors to diagnose and treat.

[0090] Example 4

[0091] On the basis of Example 1, the method for realizing a multi-modal holographic spectrum of a medical ultrasound device, the step 3 comprises:

[0092] Step 31: Accumulate and sum the key information areas corresponding to the patient to obtain the first spectrum data of the patient, identify the signal of the first spectrum data, and determine the several interference signals contained in the first spectrum data;

[0093] Step 32: Eliminate interference signals contained in the first spectrum data, perform truncation processing and Fourier transformation on the first spectrum data after the interference elimination, generate a plurality of segments of second spectrum data, and use the second spectrum data to draw a plurality of frames of spectrum images of the patient;

[0094] Step 33: obtaining a time interval T between the transmitted short pulse waveform and the N groups of long pulse waveforms, generating a data filling frequency according to the time interval T, and performing data sampling in the first image according to the data filling frequency to obtain a plurality of data to be filled;

[0095] Step 34: filling the corresponding data to be filled into the image area corresponding to each of the spectrum images according to the data filling frequency, to obtain several frames of second images of the patient.

[0096] In this example, the interference signal represents noise or other unwanted signals generated by tissue activity of the patient;

[0097] In this example, the data filling frequency is related to the time interval, and the larger the time interval, the higher the data filling frequency;

[0098] In this example, the data to be filled represents data from the first image. The sampling times are determined according to the data filling frequency. The first image is divided into a number of areas to be sampled. Then, each area to be sampled is sampled to obtain a data to be filled.

[0099] The working principle and beneficial effects of the above technical solution are as follows: first, cumulative summation is performed on the patient's key information areas to determine the patient's first spectrum data, and the second spectrum data is generated by anti-interference processing and Fourier transformation of the first spectrum data to draw a spectrum image, thereby drawing a corresponding spectrum image, and further using the first image to fill the spectrum image to obtain a second image. The doctor can diagnose the overall profile of the patient's examination area based on the second image, realizing the concept of overall inspection first and regional inspection later, and improving the doctor's inspection efficiency.

[0100] Example 5

[0101] On the basis of Example 1, the method for realizing a multi-modal holographic spectrum of a medical ultrasound device, the step 4 comprises:

[0102] Step 41: performing brightness segmentation on each of the second images respectively to obtain a plurality of image contours contained in each of the second images, and fusing and training the image contours at the same position corresponding to different second images according to the preset deflection angle to obtain foreground information corresponding to each of the second images;

[0103] Step 42: sorting the foreground information based on the arrangement order of the second image to generate a foreground information stream, establishing a virtual blood flow model of the patient according to the foreground information stream, and generating a blood flow signal of the examination site of the patient;

[0104] Step 43: Input the blood flow signal into the first image for dynamic color rendering to generate a color image of the examination site of the patient, which is regarded as the third image of the patient and displayed.

[0105] In this example, brightness segmentation refers to a process of regarding a region with the same brightness as an image contour.

[0106] The working principle and beneficial effects of the above technical solution are as follows: by performing brightness segmentation on the second image to obtain several image contours, and then fusing and training similar image contours, the foreground information of the second image is determined, and the corresponding foreground information stream is generated to establish a simulated blood flow model, thereby generating a blood flow signal, and finally using the blood flow signal to dynamically render the first image in color, generating a three-dimensional color image for doctors to view. Doctors can diagnose the patient's condition based on the image, and with the help of color dynamics, the doctor's judgment ability is improved.

[0108] Based on Example 2, the method for realizing a multi-modal holographic spectrum of a medical ultrasound device further includes:

[0109] Pre-collecting the examination part of the patient to obtain pre-collected data of the patient;

[0110] When the first image is incomplete, establishing a non-real-time state of the patient based on the pre-acquired data;

[0111] A backup image of the patient is constructed according to the non-real-time state and is regarded as a first image.

[0112] In this example, the method of pre-collecting the examination part of the patient includes: CT, MRI scanning, specific waveform scanning and other medical image collection methods.

[0113] The working principle and beneficial effects of the above technical solution: Since some older patients may experience muscle tremors, resulting in incomplete first images collected, data is collected from the patient in advance and then converted into a first image to facilitate subsequent examinations.

[0114] Example 7

[0115] Based on Example 1, the method for realizing a multi-modal holographic spectrum of a medical ultrasound device further includes:

[0116] According to the parameter extraction instruction issued by the user, the corresponding relevant parameters are extracted from the third image and displayed.

[0117] The working principle and beneficial effects of the above technical solution: the doctor can measure various parameters in the first, second and third images, including but not limited to conventional grayscale, area, shape, slope, speed, acceleration, time and various parameters derived therefrom.
