Description

Background Art

[0002] Breast tumors are one of the common tumors among female malignancies. They mainly develop from breast nodules. Therefore, early screening and diagnosis of breast nodules are beneficial for early artificial intervention to prevent the later development into tumors. With the improvement of people's living standards and the popularization of medical knowledge, the public pays more and more attention to physical health. Breast examination has become an important item in women's health check-ups, and the number of people who voluntarily undergo breast examinations is increasing day by day.

[0003] Ultrasound is currently a widely recognized imaging diagnostic method for breast diseases, with significant advantages such as economy, safety, and convenience, and has been widely used in breast examinations. People not only hope to determine whether there are nodules and their locations through ultrasound, but also hope to accurately know the types of nodules through this technology, whether they are solid nodules or false nodules. Therefore, quickly and accurately detecting the true breast tissue lesions has become the common expectation of ultrasound doctors and the public.

[0004] Currently, for ultrasound doctors during the physical examination process, there may be many pseudo-nodules shown in the collected ultrasound images, which cause great interference to the determination of solid nodules, resulting in time-consuming and laborious efforts to find and determine breast solid nodules. Doctors need to spend more time to exclude false nodules, resulting in low efficiency and prone to a high error rate. And medical diagnostic errors are very serious accidents, which makes doctors more cautious in determining solid nodules. Summary of the Invention

[0020] If it is determined that there is a solid nodule imaging in the third color Doppler ultrasound image, stabilize the vibration frequency of the vibration generator to the current vibration frequency;

[0021] If there is still no solid nodule imaging in the third color Doppler ultrasound image, continue to increase the vibration frequency of the vibration generator according to the first increment.

[0022] Optionally, if there is still no solid nodule imaging in the third color Doppler ultrasound image, continue to increase the vibration frequency of the vibration generator according to the first increment, which specifically includes:

[0023] If there is no solid nodule imaging in the third color Doppler ultrasound image and the dynamic clutter density in the third color Doppler ultrasound image does not exceed the clutter density upper limit, continue to increase the vibration frequency of the vibration generator according to the first increment;

[0024] If there is no solid nodule imaging in the third color Doppler ultrasound image and the dynamic clutter density in the third color Doppler ultrasound image exceeds the clutter density upper limit, send a prompt that there is no solid nodule in the target human body to the ultrasonic detector;

[0025] After a second preset time duration, turn off the vibration generator and switch to the standby state.

[0026] Optionally, the dynamic clutter density is the ratio of the clutter imaging area to the area of the region of interest in the third color Doppler ultrasound image.

[0053] In order to enable those of ordinary skill in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0054] It should be noted that the terms "first", "second", etc. in the description and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such data used can be interchanged under appropriate circumstances so that the embodiments of the present application described here can be implemented in an order other than those illustrated or described here. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0055] Ultrasound is a currently widely recognized imaging diagnostic method for breast diseases, with significant advantages such as economy, safety, and convenience, and has been widely used in breast examinations.

[0056] The ordinary mode of ultrasonic detection is B-ultrasound, which mainly utilizes the echo characteristics of ultrasonic waves. By emitting a group of ultrasonic waves into the human body and scanning in a certain direction, according to the detected delay time and intensity of the echoes, through electronic circuits and computer processing, a two-dimensional or three-dimensional graph of internal organs is displayed, and then the distance and nature of the organs can be judged. It is an imaging technology.

[0057] The ultrasonic color mode is color Doppler ultrasound. Simply put, it is a high-definition black-and-white B-ultrasound plus color Doppler. The key component of color Doppler ultrasound is the ultrasonic probe, which has a group of special crystals with piezoelectric effects inside. Through the special properties of the piezoelectric crystals, the conversion between electrical signals and ultrasonic waves is realized. Color Doppler ultrasound does not see the true color of human tissues, but is formed by adding false colors on the basis of black-and-white B-ultrasound images. And the false colors are mainly based on the Doppler effect. Modern medical ultrasound combines the Doppler principle. When ultrasonic waves encounter a liquid flowing away from the probe, the echo frequency will decrease, and a liquid flowing towards the probe will cause the echo frequency received by the probe to increase. Using computer false color technology for data processing enables us to determine the direction, velocity magnitude, and nature of the flowing liquid in the ultrasonic image, and superimpose this on the two-dimensional black-and-white ultrasonic image, thus forming a color Doppler ultrasound image.

[0058] At present, for ultrasound doctors during the physical examination process, the nodules in the collected ultrasound images mainly include solid nodules and non-solid nodules (pseudo-nodules). In the ordinary mode of ultrasonic detection, the two have similar imaging characteristics and cannot be clearly distinguished. In the color Doppler mode, some nodules also cannot be clearly distinguished, such as Figure 2 shown in the nodule imaging in the color Doppler mode of the ultrasound detector.

[0059] Solid nodules are mainly formed by abnormal hyperplasia of tissues in the human body's tissues and organs. That is to say, there are fillers inside the nodules, no blood flow, hard texture, uneven surface, unclear boundaries, and uneven echo shown by ultrasound, and may be accompanied by calcification and other characteristics. Non-solid nodules mainly refer to cystic-solid nodules, which are also smooth on the surface, flexible in texture, good in mobility, clear in boundary, and have uniform echo and clear boundary shown by ultrasound. There are also some pseudo-nodules that are actually normal tissues with blood still flowing inside.

[0060] In an embodiment of the present application, a nodule auxiliary detection device is provided, which is mainly used in cooperation with an ultrasound detector. For example, when an ultrasound doctor examines the breast and sees a hypoechoic area and cannot determine whether this area is a breast solid nodule, they can switch to the color Doppler mode and then place this device at the manubrium sterni. If this hypoechoic area and the surrounding tissues are covered by color signals together, it can be considered that this area has the same composition as the surrounding tissues, and it is considered normal breast tissue; if the hypoechoic area is covered by Doppler clutter signals and shows an encircling shape, it can be considered that this area has a different composition from the surrounding tissues, and it is considered a breast solid nodule. This device effectively assists doctors in detecting breast solid nodules faster and more accurately.

[0061] Such as Figure 1 shown, the present application provides an auxiliary detection method for breast solid nodules based on ultrasound Doppler. Through the ultrasound detector and the above-mentioned nodule auxiliary detection device, they act together on the target human body to improve the diagnostic accuracy of solid nodules. The specific steps are as follows:

[0062] S1: After the ultrasound detector detects at least one hypoechoic area in the B-mode ultrasound, it switches to the color Doppler mode, adds color Doppler information to the black-and-white B-mode ultrasound image to generate an initial color Doppler ultrasound image, and sends a power-on instruction to the nodule auxiliary detection device.

[0063] In some embodiments, the nodule auxiliary detection device does not need to be powered on all the time. Considering that the number of patients with solid nodules in the general population is relatively small after all. If no nodules are detected in the B-ultrasound images of some users' chests, or the doctor can clearly determine that the nodules in the users' chests are not solid nodules, then there is no need to use this nodule auxiliary detection device. Therefore, only when the ultrasonic detector switches from the ordinary B-ultrasound mode to the color Doppler mode and sends a power-on instruction to the nodule auxiliary detection device.

[0064] S2: In response to the power-on instruction, the nodule auxiliary detection device sends a Bluetooth connection request to the ultrasonic detector.

[0065] S3: After the Bluetooth connection is successful, the nodule auxiliary detection device acquires the initial color Doppler ultrasound image generated by the ultrasonic detector, starts and controls the vibration generator in the nodule auxiliary detection device to vibrate, so as to interfere with the Doppler false color of the ultrasonic detector, wherein the nodule auxiliary detection device acts on the manubrium sterni of the target human body.

[0066] A vibration generator is arranged in the nodule auxiliary detection device, and its main function is to superimpose an additional vibration wave on the ultrasonic detector in the color Doppler mode to interfere with the Doppler false color. The Doppler on the breast solid nodules will not be affected by our interference wave, so no clutter can be seen, but the Doppler on normal tissues will be affected by the interference wave, so a lot of clutter can be seen.

[0067] In some embodiments, the nodule auxiliary detection device communicates with the ultrasonic detector through an internally provided Bluetooth module. After the power-on initialization is completed and the Bluetooth pairing is completed, the nodule auxiliary detection device acquires the initial color Doppler ultrasound image generated by the ultrasonic detector.

[0068] S4: The ultrasonic detector continuously detects the target human body vibrated by the nodule auxiliary detection device, generates and sends a second color Doppler ultrasound image to the nodule auxiliary detection device.

[0069] S5: After receiving the second color Doppler ultrasound image, the nodule auxiliary detection device performs image analysis on the second color Doppler ultrasound image. When it detects the presence of a solid nodule image in the second color Doppler ultrasound image, it sends a prompt message to the ultrasonic detector.

[0070] In some embodiments, the vibration generator is a motor with a vibration frequency ranging from 30 to 2000 Hz. When initially started, the vibration frequency is the lowest frequency set by the vibration generator. After a period of time, the vibration generator can gradually increase the vibration frequency according to a certain step or increment.

[0071] In some embodiments, since the vibration frequency of the vibration generator is within a range, while the vibration frequency range that can actually help the ultrasonic detector detect solid nodules is relatively small. Therefore, the doctor can set the initial vibration frequency of the vibration generator according to the empirical value, and then increase or decrease the vibration frequency near this empirical value.

[0072] In other embodiments, since the clutter generated by the vibration generator has a greater impact on the image of the ultrasonic detector. If there is less clutter imaging, the solid nodule imaging cannot be surrounded. If there is more clutter imaging, it will cover the imaging of the solid nodule. Therefore, it is necessary to determine the vibration frequency according to the proportion of the clutter imaging area in the region of interest in the color Doppler ultrasound image, that is, the dynamic clutter density.

[0073] According to a large number of test results, if the dynamic clutter density < 30%, the clutter is too little, resulting in the inability to surround the solid nodule imaging, as Figure 3 shown. If the dynamic clutter density > 70%, the clutter is too much, and the clutter imaging will also cover the upper layer of the solid nodule imaging, as Figure 4 shown. Therefore, the vibration frequency value when the dynamic clutter density is 30% can be used as the initial minimum vibration frequency of the vibration generator, and then starting from this minimum vibration frequency, the vibration frequency is gradually increased according to certain rules.

[0074] In some embodiments, start the vibration generator and control the vibration generator to vibrate starting from the lowest vibration frequency gear; obtain the second color Doppler ultrasound image generated by the ultrasonic detector through the Bluetooth protocol, and perform image analysis on the second color Doppler ultrasound image to determine the solid nodule imaging; if the solid nodule imaging is not determined at the current vibration frequency, then increase the vibration frequency of the vibration generator by the first increment every first preset time interval until the solid nodule imaging is determined, and then stabilize the vibration frequency of the vibration generator at the current vibration frequency. Figure 5 Exemplarily shows the imaging of solid nodules assisted by the nodule auxiliary detection device in some embodiments.

[0075] S6: After the ultrasonic detector receives the prompt information, perform contour calibration on the solid nodule imaging in the second color Doppler ultrasound information. After this detection is received, send a standby instruction to the nodule auxiliary detection device.

[0076] According to the present application, a method for assisting in the detection of solid breast nodules based on ultrasound Doppler is provided. When a doctor performs an ultrasound examination on a patient, a nodule-assisted detection device is used. When the ultrasound detector detects at least one hypoechoic area in the B-mode, after switching to the color Doppler mode, the nodule-assisted detection device is applied to the manubrium sterni of the target human body, the nodule-assisted detection device is activated, the initial color Doppler ultrasound image generated by the ultrasound detector is obtained, and the vibration generator in the nodule-assisted detection device is controlled to vibrate to interfere with the Doppler false color of the ultrasound detector; after the nodule-assisted detection device receives the second color Doppler ultrasound image, the second color Doppler ultrasound image is analyzed. When a solid nodule imaging is detected in the second color Doppler ultrasound image, a prompt message is sent to the ultrasound detector, which improves the efficiency of determining solid nodules and effectively excludes the influence of false nodules on the diagnosis result. In addition, the nodule-assisted detection device is only turned on after the ultrasound detector switches to the color Doppler mode. After this detection is received, a standby command is sent to the nodule-assisted detection device, effectively extending the service life of the nodule-assisted detection device.

[0077] In some embodiments, as Figure 6 shown, if no solid nodule imaging is determined at the current vibration frequency, the vibration frequency of the vibration generator is increased by a first increment every first preset time interval, specifically including:

[0078] S51: Obtain the third color Doppler ultrasound image of the ultrasound detector through the Bluetooth protocol within the first preset time interval, and analyze the third color Doppler ultrasound image to determine solid nodule imaging;

[0079] S52: If it is determined that there is solid nodule imaging in the third color Doppler ultrasound image, the vibration frequency of the vibration generator is stabilized to the current vibration frequency.

[0080] S53: If there is still no solid nodule imaging in the third color Doppler ultrasound image, continue to increase the vibration frequency of the vibration generator by the first increment.

[0081] In some embodiments, if there is still no solid nodule imaging in the third color Doppler ultrasound image, the vibration frequency of the vibration generator is continuously increased, and it may reach the upper limit of the clutter density. Therefore, if there is no solid nodule imaging in the third color Doppler ultrasound image and the dynamic clutter density in the third color Doppler ultrasound image does not exceed the clutter density upper limit, continue to increase the vibration frequency of the vibration generator by the first increment; if there is no solid nodule imaging in the third color Doppler ultrasound image and the dynamic clutter density in the third color Doppler ultrasound image exceeds the clutter density upper limit, a prompt that there is no solid nodule in the target human body is sent to the ultrasound detector; after a second preset time interval, the vibration generator is turned off and switched to the standby state.

[0082] Since the dynamic clutter density needs to be below the upper limit and above the lower limit of the clutter density, the working duration of the nodule-assisted detection device at the ineffective vibration frequency can be greatly shortened. When the device is powered on, the dynamic clutter density corresponding to the minimum frequency is around 30%. While the vibration frequency is increased, the third color Doppler ultrasound image is synchronously acquired and the dynamic density is analyzed. If the solid nodule imaging that already exists is determined before reaching the upper limit of the clutter density, there is no need to further increase the vibration frequency. If the solid nodule imaging has not been detected yet when reaching the upper limit of the clutter density, the vibration frequency is not increased either. This method also extends the service life of the instrument.

[0083] As Figure 7 shown, the present application exemplarily shows a nodule-assisted detection device 30, which mainly acts on the manubrium sterni of the target human body. It includes an acting head 01, a vibrating rod 02, a Bluetooth module 03, a DSP processor (Digital Signal Processing) 04, a motor 05, a power supply 06, a display 07, a power adjustment button 08, a power-on button 09, an adjustment knob 10, and a bedside clip 11.

[0084] Among them, the acting head 01 is connected to the motor 03 through the vibrating rod 02. The acting head 01 acts on the surface of the target human body, and the external part includes a disposable sterilized sponge.

[0085] The Bluetooth module 03 is electrically connected to the DSP processor 04, and the DSP processor 04 is electrically connected to the motor 05. When the DSP processor 04 responds to a power-on instruction, it controls the Bluetooth module 03 to send a Bluetooth connection request to the ultrasonic detector. The ultrasonic detector and the nodule-assisted detection device 30 perform data transmission through the Bluetooth module. For example, after the Bluetooth connection is successful, the initial color Doppler ultrasound image generated by the ultrasonic detector is obtained. And, after the Bluetooth connection is successful, the DSP processor 04 starts and controls the motor to vibrate to interfere with the Doppler false color of the ultrasonic detector.

[0086] The DSP processor 04 serves as the main processor of the nodule-assisted detection device, and is used to control the connection with the ultrasonic detector through Bluetooth and obtain the color Doppler ultrasound image through the Bluetooth protocol; after receiving the color Doppler ultrasound image, it controls the motor to vibrate while performing image analysis.

[0087] The display 07 is used to display the current power magnitude. The power adjustment button 08 is used for doctors to manually adjust the vibration frequency. The power-on button 09 is used for doctors to manually power off in some special situations.

[0088] The adjustment knob 10 and the bedside clamp 11 are connected by a support rod, which is used to stabilize the nodule auxiliary detection device. The bedside clamp 11 can fix the device to the bedside, and the adjustment knob 10 can adjust the height and direction of the support rod according to the body shape and position of the target person.

[0089] It should be noted that for the specific image analysis method, object detection algorithms such as YOLOv5, R-CNN, or Fast-CNN can be used. Of course, in this embodiment, as long as the same effect can be achieved.

[0090] In some embodiments, the vibration frequency of the motor is between 30 and 2000 Hz, and the vibration frequency at the initial start is the lowest frequency set by the vibration generator. After a period of time, the vibration generator can gradually increase the vibration frequency according to a certain step or increment.

[0091] In other embodiments, since the clutter generated by the vibration generator has a greater impact on the image of the ultrasonic detector, if there is less clutter imaging, the solid nodule imaging cannot be surrounded. If there is more clutter imaging, it will cover the imaging of the solid nodule. Therefore, it is necessary to determine the vibration frequency according to the proportion of the clutter imaging area in the region of interest in the color Doppler ultrasound image, that is, the dynamic clutter density.

[0092] According to a large number of test results, if the dynamic clutter density < 30%, the clutter is too little, resulting in the inability to surround the solid nodule imaging. If the dynamic clutter density > 70%, the clutter is too much, and the clutter imaging will also cover the upper layer of the solid nodule imaging. Therefore, the vibration frequency value when the dynamic clutter density is 30% can be used as the initial minimum vibration frequency of the vibration generator, and then starting from this minimum vibration frequency, the vibration frequency can be gradually increased according to a certain rule.

[0093] The nodule auxiliary detection device provided by this application adds a clutter during the color Doppler ultrasound detection to interfere with the false color in the image, making the image of the solid nodule more obvious.
