[0065] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0066] It should be noted that the application scenarios described in the following embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. A person of ordinary skill in the art can know that with the emergence of new application scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0067] At present, since the use of ultrasound equipment for ultrasound detection has great advantages, it has become the development trend of current medical imaging technology. However, in the process of using ultrasound equipment for ultrasound detection, the operation is relatively cumbersome, which reduces the doctor's operating efficiency.

[0068] Based on this, an embodiment of the present application provides an ultrasound device and an ultrasound probe parameter setting method. The ultrasound host can determine the ultrasound probe that has been taken out based on the gyroscope and the pressure sensor, and then configure default parameters for the ultrasound probe based on the probe information of the ultrasound probe that has been taken out. The ultrasound probe under the default parameters is used to transmit and receive ultrasound signals. The ultrasound host processes the received ultrasound signals to obtain an initial image, and can perform part recognition through the image to determine the target detection part. Parameters that can perform accurate detection are configured for the ultrasound probe based on the target detection part without the doctor manually configuring parameters for the ultrasound probe. This can alleviate the problem of cumbersome operations of doctors during ultrasound detection, simplify the manual operation process during ultrasound detection, improve the doctor's operating efficiency during ultrasound detection, and reduce the possibility of doctor's operating errors.

[0069] Figure 1 A schematic diagram of an application scenario of an ultrasound probe parameter setting method provided in an embodiment of the present application is shown. Figure 1 As shown, the ultrasound device 100 may include an ultrasound host 200, a plurality of ultrasound probes 300, and a display screen 400. Among them, any of the plurality of ultrasound probes 300 is connected to the ultrasound host 200, and can be used to transmit and receive ultrasound signals, and transmit the received ultrasound signals to the ultrasound host. At the same time, the ultrasound host 200 is also connected to the display screen 400, and the display screen 400 can be used to display an ultrasound image obtained after the ultrasound host processes the ultrasound signal received by any ultrasound probe.

[0070] It is understandable that the method provided in the embodiments of the present application is not limited to Figure 1 The application scenario shown can also be used in other possible application scenarios, which are not limited in the embodiments of the present application.

[0071] Figure 2 A schematic diagram of the structure of an ultrasonic device provided in an embodiment of the present application is shown. Figure 2 As shown, the ultrasound host 200 may include a memory 210 and a processor 220, the ultrasound probe 300 may include a sensor assembly 310, and the sensor assembly 310 may include a gyroscope 311 and a pressure sensor 312, so as to collect the doctor's operation on the removed ultrasound probe in real time, and the display screen 400 and the ultrasound probe 300 are respectively connected to the ultrasound host 200. Exemplarily, the ultrasound image may be stored in the memory 210 in the ultrasound host 200, the processor 220 may perform part recognition on the ultrasound image stored in the memory 210, and the display screen 400 may display both the ultrasound image stored in the memory 210 and the recognition result after the processor 220 performs part recognition on the ultrasound image stored in the memory 210.

[0072] The memory 210 may be a volatile memory, such as a random access memory; the memory may also be a non-volatile memory, such as a read-only memory, a flash memory, a hard disk drive (HDD) or a solid-state drive (SSD), or the memory 210 may be any other medium that can be used to carry or store the desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited thereto. The memory 210 may be a combination of the above memories. The memory 210 may be used to store software programs and modules. The memory 210 may also store ultrasound images and processing results of the ultrasound images.

[0073] The processor 220 may include one or more processors. The processor 220 executes the ultrasound probe parameter setting method provided in the embodiment of the present application by running the software programs and modules stored in the memory 210 .

[0074] It is to be understood that the structure illustrated in the embodiments of the present application does not constitute a specific limitation on the node device. In other embodiments of the present application, the node device may include more or fewer components than shown in the figure, or combine certain components, or split certain components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware.

[0075] Figure 3 FIG. 1 shows a schematic diagram of the external structure of an ultrasonic probe provided in an embodiment of the present application. Figure 3 As shown, the ultrasound probe can be divided into three units, namely a holding unit, a sensor unit and a scanning unit. In the process of using the ultrasound probe, the doctor needs to hold the holding unit, operate the sensor unit, and perform ultrasound detection on the patient with the scanning unit at the same time.

[0076] Figure 4 A flow chart of a method for setting ultrasound probe parameters provided in an embodiment of the present application is shown. Figure 4 As shown, the method may include the following steps:

[0077] Step S401 : determining a target ultrasonic probe according to the distance the ultrasonic probe moves and the pressure exerted on the pressure sensor in the ultrasonic probe.

[0078] In a possible embodiment, each ultrasound probe is suitable for detecting different parts, so the doctor needs to determine the most suitable ultrasound probe for the detection part among multiple ultrasound probes according to the part that the patient needs to examine. For example, a convex array probe can be used to perform ultrasound detection on the kidney, and a linear array probe can be used to detect the carotid artery. After the doctor determines the most suitable ultrasound probe, the doctor can remove the ultrasound probe.

[0079] In a possible embodiment, any ultrasonic probe includes a sensor assembly, and the sensor assembly may include a gyroscope and a pressure sensor, wherein the pressure sensor can detect the pressure applied to any ultrasonic probe, and the gyroscope can detect the distance any ultrasonic probe moves. If it is detected that the distance moved by any ultrasonic probe among multiple ultrasonic probes reaches a first threshold, and the pressure applied to the pressure sensor in the ultrasonic probe reaches a second threshold, it can be determined that the ultrasonic probe is taken out by the doctor, that is, the ultrasonic probe can be determined as a target ultrasonic probe. For example, if the first threshold is 5 cm and the second threshold is 1 Newton, that is, if the gyroscope in ultrasonic probe A detects that the distance moved by ultrasonic probe A reaches 5 cm, and the pressure applied to the pressure sensor in ultrasonic probe A reaches 1 Newton, then it can be considered that ultrasonic probe A is taken out by the doctor, that is, ultrasonic probe A can be determined as a target ultrasonic probe. Among them, the first threshold can also be 3 cm or 7 cm, etc.; the second threshold can also be 0.7 Newton or 1.3 Newton, etc., which is not limited in this application.

[0080] Step S402: configuring first parameters for the target ultrasound probe according to the probe information of the target ultrasound probe and the correspondence between the pre-stored probe information and the probe parameters.

[0081] In a possible embodiment, after determining the target ultrasonic probe, the ultrasound host may obtain the probe information of the target ultrasonic probe, and configure the first parameter for the target ultrasonic probe according to the probe information and the correspondence between the pre-stored probe information and the probe parameters. The probe information may include the serial number of the ultrasonic probe taken out; the correspondence between the pre-stored probe information and the probe parameters may include the maximum threshold and the minimum threshold of each probe parameter corresponding to the serial number of the ultrasonic probe taken out. The probe parameters may include data such as the detection depth of the ultrasonic probe, the detection focus of the ultrasonic probe, and the detection gain of the ultrasonic probe. Different parameters have different effects on detection. For example, different detection depth parameters can detect parts of different depths, and different detection gains can correspond to different transmission powers, so that after the ultrasonic host processes the ultrasonic signal received by the ultrasonic probe, the clarity of the ultrasonic image obtained changes.

[0082] Exemplarily, the detection mode of the target ultrasonic probe can be set to B mode, and most of the parameters in the first parameter can be configured as the middle value between the maximum threshold and the minimum threshold. That is to say, if there is a probe B, the detection mode of probe B can be set to B mode by default. If the maximum depth that probe B can detect is 7 cm and the minimum is 3 cm, then in the first parameter, the detection depth parameter of probe B can be set to 5 cm. In addition to the detection depth parameter, the detection gain parameter, detection corner point parameter, etc. can all be set using the same method. It is worth noting that the detection mode of the target ultrasonic probe can be set to other modes such as C mode or CW mode by default, and the values ​​of most of the parameters in the first parameter can also be set to a value higher than the middle value or to a value lower than the middle value. This application does not limit this.

[0083] In another possible embodiment, if the gyroscope of the target ultrasonic probe detects that the duration of the target ultrasonic probe being in the set direction reaches the first time threshold, and the pressure sensor of the target ultrasonic probe has no induction, then it is determined that the target ultrasonic probe is placed in the probe cup. The set direction is consistent with the orientation of the probe cup. If the direction of the probe cup is vertically upward, then the set direction is also vertically upward. For example, if the first time threshold is 3 seconds, the direction of the probe cup is vertically upward, if it is detected that the target ultrasonic probe C is vertically upward for 3 seconds, and within these 3 seconds, the pressure sensor of the target ultrasonic probe C has no induction, then it can be determined that the target ultrasonic probe C is placed in the probe cup.

[0084] After configuring the first parameters for the target ultrasound probe according to the probe information of the target ultrasound probe and the correspondence between the pre-stored probe information and the probe parameters, the target ultrasound probe can be used to transmit and receive ultrasound signals to the patient's part to be detected, and then step S403 is executed.

[0085] Step S403: performing part recognition on the initial ultrasonic image to determine the target detection part corresponding to the initial ultrasonic image.

[0086] In a possible embodiment, the initial image is an ultrasound image obtained by processing the ultrasound signal received by the target ultrasound probe configured with the first parameter. The initial ultrasound image is input into the image recognition model, and the detection part corresponding to the initial ultrasound image output by the image recognition model can be obtained, wherein the image recognition model can be a machine learning model stored in the processor of the ultrasound host. Before the ultrasound detection starts, the machine learning model can be trained using a plurality of ultrasound images of different parts collected in advance, so that the machine learning model can be classified according to the pictures of different parts. For example, the specific training process can be repeatedly executing the following steps: extracting sample images from a plurality of ultrasound images; inputting the sample images into the image recognition model to be trained, and obtaining the predicted detection part output by the image recognition model to be trained; determining the loss value according to the predicted detection part and the detection part label of the sample image; adjusting the network parameters in the image recognition model to be trained according to the loss value; until the determined loss value converges, the trained image recognition model is obtained. After the ultrasound detection starts, when the doctor aims the scanning unit of the ultrasound probe at the patient's part to be detected, the machine learning model can perform part recognition according to the initial ultrasound image transmitted by the ultrasound probe to the ultrasound host. For example, if the doctor aims the scanning unit of the ultrasound probe at the patient's stomach, the machine learning model stored in the processor of the ultrasound host can identify the initial ultrasound image of the patient transmitted by the ultrasound probe to the ultrasound host, and can identify that the initial ultrasound image is an initial ultrasound image of the stomach.

[0087] In a possible embodiment, after the processor of the ultrasound host performs site recognition based on the initial ultrasound image, the predicted detection site corresponding to the initial ultrasound image may be displayed on a display screen. For example, if the predicted detection site recognized for the initial ultrasound image is the kidney, then Figure 5 As shown, the following prompt may be displayed on the display screen: The identification result is kidney, please click the handle to confirm, or double-click the handle to exit. The doctor's single-click operation according to the prompt displayed on the display screen may be the first operation. If the ultrasound host receives the first operation, it is determined that the doctor's confirmation operation for the predicted detection site is received. Figure 6 As shown, if the first trigger operation performed by the doctor according to the prompt displayed on the display screen is a single-click confirmation operation, the predicted detection part can be confirmed as the target detection part, and step S404 is continued; Figure 7 As shown, if the doctor double-clicks to exit according to the prompt on the display screen, the sensor component on the ultrasound probe and the machine learning model in the ultrasound host will be turned off. At the same time, the doctor will manually intervene to perform ultrasound detection based on the ultrasound image on the display screen.

[0088] Step S404: configuring second parameters for the target ultrasound probe according to the target detection part and the pre-stored correspondence between the detection part and the probe parameters.

[0089] In a possible embodiment, the first parameter configured for the target ultrasound probe is a parameter that allows the target ultrasound probe to perform ultrasound detection normally in most detection environments, but it is not necessarily the optimal parameter for detecting the patient's to-be-detected part. For example, if probe D is used as the target probe, the depth that can be detected is 7 cm to 13 cm. In the first parameter configured for the target ultrasound probe, the detection depth of probe D can be configured to 10 cm. However, in the actual detection process, the detection depth of probe D can be configured to 12 cm as needed to better detect deeper organs, or the detection depth of probe D can be configured to 8 cm to better detect shallower parts.

[0090] Therefore, after completing the part recognition of the initial ultrasound image and determining the target detection part corresponding to the initial ultrasound image, the second parameter can be configured for the target ultrasound probe according to the determined target detection part and the correspondence between the pre-stored detection part and the ultrasound probe parameters. Among them, the second parameter configured for the target ultrasound probe is more suitable for detecting the patient's to-be-detected part than the first parameter configured for the target ultrasound probe. Exemplarily, the correspondence between the pre-stored detection part and the probe parameters may include: when the detection part is the stomach, the probe parameters include that the detection depth of the ultrasound probe can be set to 6 cm, the detection focus of the ultrasound probe can be set to 7 cm, etc. The pre-stored detection parts are different, and the probe parameters corresponding to the pre-stored detection parts are also different.

[0091] In a possible embodiment, after configuring the second parameter for the target ultrasound probe, the target ultrasound probe may be used to continue ultrasound detection, such as Figure 8 As shown, the following prompt may be displayed on the display screen: Parameter configuration is successful, please continue the test. The doctor can click the handle to confirm and then perform the ultrasound test.

[0092] In a possible embodiment, the ultrasound host may freeze the ultrasound image displayed on the display screen according to the received second operation of the doctor on the target ultrasound probe, wherein the second operation may be Figure 6The single-click operation is the same as shown, and it can also be to continuously trigger the sensor at the handle of the ultrasound probe, or it can be to change the strength of holding the probe handle, which is not limited in this application. That is to say, during the ultrasound detection process, if the doctor believes that the ultrasound image obtained at a certain moment is valuable, then a second operation can be performed on the handle of the target ultrasound probe at that moment, and then the ultrasound image at that moment can be frozen. For example, if at a certain moment, the target ultrasound probe scans the patient's liver, and the doctor freezes the ultrasound image at that moment, the frozen ultrasound image can be as follows: Fig. 9 Compared with the current situation where doctors need to find a freeze button on the ultrasound host to perform a freeze operation, the method provided by the embodiment of the present application is simpler and more convenient, and improves the doctor's operating efficiency.

[0093] In a possible embodiment, after the ultrasound image is frozen, the ultrasound host can measure the detection part in the frozen ultrasound image and mark the measurement result in the ultrasound image. Fig. 9 FIG. 4 shows a frozen ultrasound image of the liver. At this time, the ultrasound host can identify the lesion in the ultrasound image and mark the lesion and the size of the lesion next to the frozen ultrasound image, such as Fig.10 Shown, labeled as: tumor, approximately 4 cm in diameter.

[0094] In a possible embodiment, the ultrasound host may save the frozen ultrasound image according to the received third trigger operation of the user on the target ultrasound probe, wherein the third operation may be Figure 7 The double-click operation shown in the figure can also be to continuously trigger the sensor at the handle of the ultrasound probe, or to change the strength of holding the handle of the probe, which is not limited in this application. After the doctor saves the frozen ultrasound image, the display screen can show the following: Fig.11 The picture shown is saved successfully.

[0095] It should be noted that after the doctor saves the ultrasound image, the doctor can also choose to switch the ultrasound probe mode to re-perform ultrasound detection. Even if it is the same ultrasound probe, different modes will correspond to different applications. For example, the B mode of the ultrasound probe can provide a two-dimensional black-and-white ultrasound image, which can clearly display the morphological structure of organs and tissues, and has a better effect on observing static structures, such as detecting the size, shape, and contour of the stomach; the C mode of the ultrasound probe can measure blood flow velocity by continuously sending and receiving ultrasonic signals, for example, detecting the blood flow of the heart, arteries, and veins.

[0096] Therefore, different ultrasound probe modes can be switched in different ways. Fig.12As shown in the figure, the doctor can switch to C mode by drawing a semicircle while holding the ultrasound probe; Fig.13 As shown in FIG. 1 , the doctor can switch to the CW mode by moving the ultrasound probe up and down and back and forth once while holding the ultrasound probe; Fig.14 As shown, the doctor can switch to the PW mode by moving the ultrasound probe back and forth once while holding the ultrasound probe. It should be noted that the mode switching can be performed in a manner including but not limited to the above operations, and the switching mode also includes but is not limited to the above modes, which is not limited in this application.

[0097] In a specific embodiment, a process of an ultrasound probe parameter setting method executed by an ultrasound host of an ultrasound device can be as follows: Fig.15 As shown, the following steps are included:

[0098] Step S1501 : determining a target ultrasonic probe according to the distance the ultrasonic probe moves and the pressure exerted on the pressure sensor in the ultrasonic probe.

[0099] Step S1502: configuring first parameters for the target ultrasound probe according to the probe information of the target ultrasound probe and the correspondence between the pre-stored probe information and the probe parameters.

[0100] In a possible embodiment, the target ultrasound probe is a probe that a doctor takes out from a probe cup when performing ultrasound testing. After configuring the first parameter for the target ultrasound probe, the target ultrasound probe can be used to transmit and receive ultrasound signals, and the received ultrasound signals can be transmitted to an ultrasound host, and the ultrasound host processes the received ultrasound signals to obtain an initial ultrasound image.

[0101] Step S1503: perform site recognition on the initial ultrasonic image, and display the predicted detection site corresponding to the initial ultrasonic image on a display screen.

[0102] Step S1504: If a first operation of the user on the target ultrasound probe is received, the target detection part corresponding to the initial ultrasound image is determined according to the predicted detection part.

[0103] Step S1505: configuring second parameters for the target ultrasound probe according to the target detection part and the pre-stored correspondence between the detection part and the probe parameters.
