[0065] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

Those 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 ultrasound detection by using an ultrasound device has great advantages, ultrasound detection by using an ultrasound device has become a development trend of current medical imaging technology. However, in the process of ultrasound detection by using an ultrasound device, the operation is relatively cumbersome, which reduces the operation efficiency of doctors.

At the same time, the ultrasonic host 200 is also connected with the display screen 400, and the display screen 400 can be used to display the ultrasonic image obtained by the ultrasonic host processing the ultrasonic signals received by any ultrasonic probe.

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

[0071] Figure 2 A structure schematic diagram of an ultrasonic device provided by the embodiment of the present application is shown, as shown in Figure 2 The ultrasonic host 200 can include a memory 210 and a processor 220, and the ultrasonic probe 300 can include a sensor assembly 310. The sensor assembly 310 can include a gyroscope 311 and a pressure sensor 312, so as to collect the operation of the doctor on the ultrasonic probe taken out in real time. The display screen 400 is connected with the ultrasonic probe 300 and the ultrasonic host 200. The ultrasonic image can be saved in the memory 210 in the ultrasonic host 200. The processor 220 can perform part identification on the ultrasonic image saved in the memory 210. The display screen 400 can display the ultrasonic image saved in the memory 210, or the identification result after the processor 220 performs part identification on the ultrasonic image saved in the memory 210.

[0072] The memory 210 can be a volatile memory, such as a random access memory; the memory can 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 can be any other medium capable of carrying or storing desired program codes in the form of instructions or data structures and capable of being accessed by a computer, but is not limited thereto. The memory 210 can be a combination of the above memories. The memory 210 can be used to store software programs and modules. The memory 210 can also store ultrasound images and processing results of the ultrasound images.

[0073] The processor 220 can include one or more processors, and the processor 220 executes the software programs and modules stored in the memory 210, thereby performing the method for setting parameters of an ultrasound probe as provided in the embodiments of the present application.

[0074] It can 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 can include more or fewer components than the illustration, or combine certain components, or split certain components, or different arrangement of components. The illustrated components can be implemented in hardware, software or a combination of software and hardware.

[0075] Figure 3 An external structure diagram of an ultrasound probe is shown, as provided in an embodiment of the present application, as shown in Figure 3 The ultrasound probe can be divided into three units, namely a holding unit, a sensor unit and a scanning unit. During use of the ultrasound probe, the doctor needs to hold the holding unit, operate the sensor unit, and simultaneously use the scanning unit to perform ultrasound detection on the patient.

[0076] Figure 4 A flowchart of a method for setting parameters of an ultrasound probe is shown, as provided in an embodiment of the present application, as shown in Figure 4 The method can include the following steps:

[0077] In step S401, a target ultrasound probe is determined according to a distance moved by the ultrasound probe and a pressure experienced by a pressure sensor in the ultrasound probe.

[0078] In one possible embodiment, each ultrasound probe is suitable for detecting different parts, and therefore the doctor needs to determine the ultrasound probe most suitable for the part to be detected among multiple ultrasound probes according to the part to be examined by the patient, 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 take out the ultrasound probe.

[0079] In a possible embodiment, any of the ultrasound probes comprises a sensor assembly, which can comprise a gyroscope and a pressure sensor. The pressure sensor can detect the pressure on any of the ultrasound probes, and the gyroscope can detect the distance of movement of any of the ultrasound probes. If the distance of movement of any of the ultrasound probes reaches a first threshold value, and the pressure on the pressure sensor of the ultrasound probe reaches a second threshold value, it can be determined that the ultrasound probe is taken out by the doctor, that is, the ultrasound probe can be determined as the target ultrasound probe. For example, if the first threshold value is 5 cm and the second threshold value is 1 N, that is, if the gyroscope in the ultrasound probe A detects that the distance of movement of the ultrasound probe A reaches 5 cm, and the pressure on the pressure sensor in the ultrasound probe A reaches 1 N, it can be considered that the ultrasound probe A is taken out by the doctor, that is, the ultrasound probe A can be determined as the target ultrasound probe. The first threshold value can also be 3 cm or 7 cm, and the second threshold value can also be 0.7 N or 1.3 N, which are not limited in the present application.

[0080] In step S402, the first parameter is configured 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 parameter.

[0081] In a possible embodiment, after the target ultrasound probe is determined, the ultrasound host can obtain the probe information of the target ultrasound probe, and configure the first parameter for the target ultrasound probe according to the probe information and the correspondence between the pre-stored probe information and the probe parameter. The probe information can comprise the number of the taken-out ultrasound probe, and the correspondence between the pre-stored probe information and the probe parameter can comprise the maximum threshold value and the minimum threshold value of each probe parameter corresponding to the number of the taken-out ultrasound probe. The probe parameter can comprise the detection depth of the ultrasound probe, the detection focal point of the ultrasound probe, the detection gain of the ultrasound probe, and the like. Different parameters have different influences on detection, for example, different detection depth parameters can detect different depth parts, and different detection gains can correspond to different transmission powers, so that the ultrasound host changes the definition of the ultrasound image obtained after processing the ultrasound signal received by the ultrasound probe.

[0082] Exemplarily, the detection mode of the target ultrasound probe can be set as B mode, most of the parameters in the first parameters are configured as the middle value between the maximum threshold value and the minimum threshold value, that is, if there is a probe B, the detection mode of the probe B can be set as B mode by default, if the maximum detection depth of the probe B is 7 cm and the minimum detection depth is 3 cm, then in the first parameters, the detection depth parameter of the probe B can be set as 5 cm, and the detection gain parameter, the detection angle parameter and the like can be set by using the same method. It is worth noting that the detection mode of the target ultrasound probe can be set as C mode or CW mode or other modes by default, and the values of most of the parameters in the first parameters can be set as a value higher than the middle value or a value lower than the middle value, which is not limited in the present application.

[0083] In another possible embodiment, if it is detected by the gyroscope of the target ultrasound probe that the target ultrasound probe is in a set direction for a first time threshold, and the pressure sensor of the target ultrasound probe is not sensitive, it is determined that the target ultrasound probe is placed in the probe cup. Wherein, the set direction is consistent with the direction of the probe cup, if the direction of the probe cup is vertical upward, then the set direction is also vertical upward. Exemplarily, if the first time threshold is 3 seconds, the direction of the probe cup is vertical upward, if it is detected that the target ultrasound probe C is in the vertical upward direction for 3 seconds, and the pressure sensor of the target ultrasound probe C is not sensitive in the 3 seconds, it can be determined that the target ultrasound probe C is placed in the probe cup.

[0084] After the first parameters are configured 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 emit and receive ultrasound signals to the part to be detected of the patient, and then step S403 is performed.

[0085] In step S403, the initial ultrasound image is subjected to part recognition to determine the target detection part corresponding to the initial ultrasound image.

[0086] In a possible embodiment, the initial image is an ultrasound image obtained by processing an ultrasound signal received by the target ultrasound probe configured with the first parameter, and the initial ultrasound image is input into the image recognition model to obtain a detected part corresponding to the initial ultrasound image output by the image recognition model. 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 classify different parts according to the images. For example, the training process can include the following steps: extracting a sample image from the plurality of ultrasound images; inputting the sample image into the image recognition model to be trained to obtain a predicted detected part output by the image recognition model to be trained; determining a loss value according to the predicted detected part and a detected part label of the sample image; adjusting network parameters in the image recognition model to be trained according to the loss value; and obtaining the trained image recognition model until the determined loss value converges. After the ultrasound detection starts, the machine learning model can perform part recognition according to the initial ultrasound image transmitted by the ultrasound probe to the ultrasound host when the doctor aligns the scanning unit of the ultrasound probe to the detected part of the patient. For example, if the doctor aligns the scanning unit of the ultrasound probe to the stomach of the patient, the machine learning model stored in the processor of the ultrasound host can recognize the initial ultrasound image of the patient transmitted by the ultrasound probe to the ultrasound host, and can recognize 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 part recognition according to the initial ultrasound image, the processor can display the predicted detected part corresponding to the initial ultrasound image on the display screen. For example, as shown in FIG. 4B, if the predicted detected part recognized according to the initial ultrasound image is a kidney, the following prompt can be displayed on the display screen: The recognition result is a kidney. Please click the handle to confirm, or double-click the handle to exit. The single-click operation of the doctor according to the prompt displayed on the display screen can be a first operation, and if the ultrasound host receives the first operation, it is determined that the doctor's confirmation operation for the predicted detected part is received. Figure 5 Figure 6 As shown in FIG. 4C, if the first trigger operation of the doctor according to the prompt displayed on the display screen is the single-click confirmation operation, the predicted detected part can be confirmed as the target detected part, and step S404 can be continued. As shown in FIG. 4D, if the double-click exit operation of the doctor according to the prompt displayed on the display screen is performed, the sensor assembly on the ultrasound probe and the machine learning model in the ultrasound host are closed, and the doctor performs manual intervention according to the ultrasound image on the display screen to perform ultrasound detection. Figure 7

[0088] ​​In step S404, the second parameter is configured for the target ultrasound probe according to the target detection site and the pre-stored corresponding relationship between the detection site and the probe parameter.

[0089] In a possible embodiment, the first parameter configured for the target ultrasound probe is a parameter that can enable the target ultrasound probe to normally perform ultrasound detection in most detection environments, but is not necessarily the optimal parameter for detecting the to-be-detected site of the patient. For example, if the probe D is taken as the target probe, the detection depth of the probe D can be configured as 10 cm in the first parameter configured for the target ultrasound probe, but in actual detection, the detection depth of the probe D can be configured as 12 cm according to the requirement, so as to better detect deeper organs, or the detection depth of the probe D can be configured as 8 cm, so as to better detect shallower sites.

[0090] Therefore, after the site recognition on the initial ultrasound image is completed and the target detection site corresponding to the initial ultrasound image is determined, the second parameter can be configured for the target ultrasound probe according to the determined target detection site and the pre-stored corresponding relationship between the detection site and the probe parameter. The second parameter configured for the target ultrasound probe is more suitable for detecting the to-be-detected site of the patient than the first parameter configured for the target ultrasound probe. For example, the pre-stored corresponding relationship between the detection site and the probe parameter can include that when the detection site is the stomach, the parameters of the probe include that the detection depth of the ultrasound probe can be set as 6 cm and the detection focal point of the ultrasound probe can be set as 7 cm. The pre-stored corresponding relationship between the detection site and the probe parameter is different.

[0091] In a possible embodiment, after the second parameter is configured for the target ultrasound probe, the target ultrasound probe can be used to continue the ultrasound detection, for example, Figure 8 As shown in FIG. 6, the following prompt can be displayed on the display screen: parameter configuration is successful, please continue the detection. The doctor can click the handle to confirm, and then perform the ultrasound detection.

[0092] In a possible embodiment, the ultrasound host can perform the freezing operation on the ultrasound image displayed on the display screen according to the second operation of the doctor on the target ultrasound probe. The second operation can be the same as the first operation. Figure 6The single click operation shown is the same, and can also be continuous triggering of the sensor at the handle of the ultrasound probe, or changing the force with which the handle of the ultrasound probe is held, which are not limited in the present application. That is, during the ultrasound detection, if the doctor considers that the ultrasound image obtained at a moment is valuable, a second operation can be performed on the handle of the target ultrasound probe at the moment, and then the ultrasound image at the moment can be frozen. For example, if at a moment the target ultrasound probe scans the liver of the patient, the doctor freezes the ultrasound image at the moment, and the frozen ultrasound image can be as shown in Figure 9 Compared with the current situation in which the doctor needs to find the freeze button on the ultrasound host to perform the freeze operation, the method provided in the embodiments of the present application is more convenient, and improves the operation efficiency of the doctor.

[0093] In a possible embodiment, after the ultrasound image is frozen, the ultrasound host can measure the detected part in the frozen ultrasound image, and mark the measurement result in the ultrasound image. For example, Figure 9 The ultrasound image of the frozen liver is shown, at this time, the ultrasound host can identify the lesion in the ultrasound image, and mark the lesion and the size of the lesion beside the frozen ultrasound image, as shown in Figure 10 The mark is: tumor, about 4 cm in diameter.

[0094] In a possible embodiment, the ultrasound host can save the frozen ultrasound image according to the third triggering operation of the user on the target ultrasound probe, wherein the third operation can be the same as the double click operation shown in Figure 7 The single click operation shown is the same, and can also be continuous triggering of the sensor at the handle of the ultrasound probe, or changing the force with which the handle of the ultrasound probe is held, which are not limited in the present application. After the doctor performs the save operation on the frozen ultrasound image, the display screen can display the picture save success prompt as shown in Figure 11

[0095] It should be noted that after the doctor saves the ultrasound picture, the doctor can also select to switch the mode of the ultrasound probe to re-perform ultrasound detection. Even if it is the same ultrasound probe, different modes 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 show the morphological structure of organs and tissues, and is good for observing static structures, for example, detecting the size, shape and contour of the stomach; the C mode of the ultrasound probe can measure the blood flow velocity by continuously sending and receiving ultrasound signals, for example, detecting the blood flow of the heart, arteries and veins, etc.

[0096] Therefore, different ultrasound probe modes can be switched in different ways. For example, as shown in Figure 12 ​As shown, the doctor can draw a semicircle while holding the ultrasound probe, i.e. switch to the C mode; as Figure 13 As shown, the doctor can translate the ultrasound probe up and down once while holding the ultrasound probe, i.e. switch to the CW mode; as Figure 14 As shown, the doctor can translate the ultrasound probe back and forth once while holding the ultrasound probe, i.e. switch to the PW mode. It should be noted that the mode switching can be performed in a manner including but not limited to the above operations, and the switched mode also includes but is not limited to the above modes, which are not limited herein.

[0097] In a specific embodiment, the flow of an ultrasound probe parameter setting method performed by an ultrasound host of an ultrasound device can be as shown in Figure 15 As shown, the flow includes the following steps:

[0098] Step S1501, determining a target ultrasound probe according to the distance of the movement of the ultrasound probe and the pressure borne by the pressure sensor in the ultrasound probe.

[0099] Step S1502, configuring a first parameter 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 parameter.

[0100] In a possible embodiment, the target ultrasound probe is the probe taken out of the probe cup by the doctor during the ultrasound detection. After the first parameter is configured for the target ultrasound probe, the target ultrasound probe can be used to emit and receive the ultrasound signal, and the received ultrasound signal can be transmitted to the ultrasound host, and the initial ultrasound image can be obtained by processing the received ultrasound signal by the ultrasound host.

[0101] Step S1503, performing part recognition on the initial ultrasound image, and displaying the predicted detection part corresponding to the initial ultrasound image on the display screen.

[0102] Step S1504, if receiving the first operation of the user on the target ultrasound probe, determining the target detection part corresponding to the initial ultrasound image according to the predicted detection part.

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

[0104] Step S1506, according to the received second operation of the user on the pressure sensor of the target ultrasound probe, freezing the ultrasound image displayed on the display screen.

[0105] Step S1507, after freezing the ultrasound image displayed on the display screen, measuring the corresponding target detection part in the ultrasound image, and marking the measurement result in the ultrasound image.
