[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0053] In the related technology for cardiac ultrasound, a prompt interface is provided to assist the user in scanning the cardiac section, so as to provide guidance for the cardiac ultrasound scanning. For example, the prompt interface includes a standard cardiac section image and section name, previous and next operation controls, section accuracy, probe position instructions, etc. However, since this solution is set for cardiac scanning, it is only applicable to cardiac scanning and is difficult to apply to other scenarios.

[0054] Based on this, an embodiment of the present invention provides an ultrasound device and a guidance method for ultrasound scanning, which provides guidance to the operating user by displaying scanning guidance information in the guidance area of ​​the interface, instructing the user to perform ultrasound scanning, standardizing the rapid scanning process without omissions, and thereby improving the accuracy and efficiency of ultrasound scanning.

[0055] An embodiment of the present invention provides an ultrasound device, including an ultrasound probe, a display, and a processor, wherein the processor is in communication with the ultrasound probe and the display, the processor is used to execute the method for guiding ultrasound scanning described in any of the following embodiments, and the display is used to display a guidance area and an image display area. Of course, the function of the display is not limited to this, and is specifically set according to actual needs.

[0056] See also Figure 1 , Figure 1 1 is a schematic diagram of the structure of an ultrasound device provided by an optional embodiment of the present invention, in which the ultrasound device 100 includes an ultrasound probe 110, a transmitting circuit 112, a receiving circuit 114, a processor 116, and a display 118. Further, the ultrasound device may also include a transmitting / receiving selection switch 120 and a beamforming module 122, and the transmitting circuit 112 and the receiving circuit 114 may be connected to the ultrasound probe 110 through the transmitting / receiving selection switch 120.

[0057] Specifically, the ultrasonic probe 110 is used to generate a shear wave that propagates in the target tissue of the target object; the transmitting circuit 112 is used to excite the ultrasonic probe 110 to transmit a first ultrasonic wave that tracks the shear wave to the target tissue; the receiving circuit 114 is used to control the ultrasonic probe 110 to receive the ultrasonic echo returned by the target tissue to obtain a first echo signal of the first ultrasonic wave; the processor 116 is used to execute the method of guiding ultrasonic scanning described in any of the following embodiments.

[0058] The ultrasonic probe 110 includes a transducer (not shown) composed of a plurality of array elements arranged in an array. The array elements are used to transmit ultrasonic waves according to an excitation electrical signal, or to convert received ultrasonic waves into electrical signals. Therefore, each array element can be used to realize the mutual conversion between electrical pulse signals and ultrasonic waves, thereby transmitting ultrasonic waves to the biological tissue of the target object, and can also be used to receive the echo of ultrasonic waves reflected back by the tissue.

[0059] The transmitting circuit 112 is used to control the ultrasonic probe 110 to transmit ultrasonic waves, for example, according to the control of the processor 116, stimulate the ultrasonic probe 110 to transmit ultrasonic waves toward the target object.

[0060] The receiving circuit 114 is used to control the ultrasonic probe 110 to receive ultrasonic echoes, for example, to receive ultrasonic echoes returned from the target object through the ultrasonic probe 110 to obtain ultrasonic echo signals, and can also process the ultrasonic echo signals. The receiving circuit 114 may include one or more amplifiers, analog-to-digital converters (ADCs), etc.

[0061] The display 118 is used for display or human-computer interaction, such as outputting visual information and receiving user input. The display 118 includes an input device and at least one display screen. The input device is used to receive user input, which can be a keyboard, operation button, mouse, trackball, touch pad, etc., or a touch screen integrated with the display screen.

[0062] The memory 124 is used to store various types of data.

[0063] The ultrasound device may also include a beamforming module 122. The beamforming module 122 is connected to the receiving circuit 114 signal, and is used to perform corresponding delay and weighted summing beamforming processing on the echo signal. Since the distances from the ultrasound receiving point in the measured tissue to the receiving array element are different, the channel data of the same receiving point output by different receiving array elements have delay differences, and delay processing is required to align the phases, and weighted summing is performed on the different channel data of the same receiving point to obtain the ultrasound image data after beamforming. The ultrasound image data output by the beamforming module 122 is also called radio frequency data (RF data). The beamforming module 122 performs focusing delay, weighting and channel summing on the ultrasound echo data, and then sends it to the processor 116. The processor 116 performs signal detection, signal enhancement, data conversion, logarithmic compression and other processing on the ultrasound echo signal to form an ultrasound image. The ultrasound image obtained by the processor 116 can be displayed on the display 118 or stored in the memory 124.

[0064] The processor 116 may be implemented as software, hardware, firmware or any combination thereof, and may use a single or multiple application specific integrated circuits (ASICs), a single or multiple general purpose integrated circuits, a single or multiple microprocessors, a single or multiple programmable logic devices, or any combination of the aforementioned circuits and / or devices, or other suitable circuits or devices. In addition, the processor 116 may control other components in the ultrasound device 100 to perform the corresponding steps of the methods in various embodiments of the present specification.

[0065] The display 118 is connected to the processor 116, and the display 118 may be a touch screen, a liquid crystal display, etc.; or, the display 118 may be an independent display such as a liquid crystal display, a television, etc., which is independent of the ultrasound device 100; or, the display 118 may be a display screen of an electronic device such as a smart phone or a tablet computer, etc. The number of the display 118 may be one or more.

[0066] The display 118 can display the ultrasound image obtained by the processor 116. In addition, while displaying the ultrasound image, the display 118 can also provide the user with a graphical interface for human-computer interaction. One or more controlled objects are set on the graphical interface, and the user is provided with a human-computer interaction device to input operation instructions to control these controlled objects, thereby performing corresponding control operations. For example, an icon is displayed on the graphical interface, and the icon can be operated by the human-computer interaction device to perform a specific function, such as drawing a region of interest box on the ultrasound image.

[0067] Optionally, the ultrasound device 100 may further include other human-computer interaction devices in addition to the display 118, which are connected to the processor 116. For example, the processor 116 may be connected to the human-computer interaction device via an external input / output port, and the external input / output port may be a wireless communication module, or a wired communication module, or a combination of the two. The external input / output port may also be implemented based on USB, bus protocols such as CAN, and / or wired network protocols.

[0068] The human-computer interaction device may include an input device for detecting user input information, which may be, for example, a control instruction for ultrasonic transmission / reception timing, an operation input instruction for drawing points, lines or frames on an ultrasonic image, or other instruction types. The input device may include a keyboard, a mouse, a scroll wheel, a trackball, a mobile input device (such as a mobile device with a touch screen, a mobile phone, etc.), a multi-function knob, etc., or a combination of multiple thereof. The human-computer interaction device may also include an output device such as a printer.

[0069] The ultrasound device 100 may further include a memory 124 for storing instructions executed by the processor, storing received ultrasound echoes, storing ultrasound images, etc. The memory may be a flash memory card, a solid-state memory, a hard disk, etc. It may be a volatile memory and / or a non-volatile memory, a removable memory and / or a non-removable memory, etc.

[0070] According to an embodiment of the present invention, a method embodiment for guiding ultrasonic scanning is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0071] In this embodiment, a method for guiding ultrasonic scanning is provided, which can be used in the above-mentioned ultrasonic device. Figure 2 is a flow chart of a method for guiding ultrasonic scanning according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0072] S11, obtaining the target scanning protocol of the current ultrasound scanning.

[0073] The scanning protocol is associated with the scanning part, the total number of scanning sections of the scanning part, etc., and the association is pre-set in the ultrasound device. Of course, the association can also be added, deleted, or modified according to the actual application scenario.

[0074] In some optional implementations, the scanning protocols include FAST protocol, eFAST protocol, BLUE protocol, RUSH protocol, CCUE (ICU) protocol, and the like.

[0075] The scanning protocol can be obtained by the ultrasound device communicating with a third-party device, and the third-party device sending the protocol to the ultrasound device; or the ultrasound device can provide a human-computer interaction function, and the user can determine the target scanning protocol by interacting with the ultrasound device. For example, multiple scanning protocols are set in the ultrasound device, and when an ultrasound scan is required, multiple scanning protocols are displayed in a list or other form on the interface of the ultrasound device, and the user determines the target scanning protocol by interactive selection operations on the interface.

[0076] In some optional implementations, the interface also displays descriptions of each scanning protocol to assist the user in selecting a scanning protocol. For example, scanning protocol A corresponds to applicable scanning parts a1 and a2, applicable scanning scenarios, etc. The specific descriptions of each scanning protocol are set according to actual needs and are not limited here.

[0077] As an optional application scenario, the ultrasound device is connected to the central station. The user sets the target scanning protocol of the current ultrasound scan in the central station and sends the target scanning protocol to the corresponding ultrasound device. Accordingly, the ultrasound device can obtain the target scanning protocol of the current ultrasound scan.

[0078] As another optional application scenario, the ultrasound device provides a human-computer interaction interface. The user selects a scanning protocol by interacting with the human-computer interaction interface to obtain a target scanning protocol.

[0079] S12, determining scanning guidance information based on the target scanning protocol.

[0080] The scanning guidance information includes the part to be scanned and the total number of sections of the part to be scanned.

[0081] As described above, there is an association between the scanning protocol and the scanning part, the total number of scanning sections of the scanning part, etc. Based on this, after obtaining the target scanning protocol, the target scanning protocol is used to query the association to determine the scanning guidance information corresponding to the target scanning protocol.

[0082] The scanning guidance information includes the part to be scanned and the total number of sections of the part to be scanned. For example, the total number of sections corresponding to the part A to be scanned is c1; the total number of sections corresponding to the part B to be scanned is c2. When performing ultrasound scanning based on the scanning guidance information, the user can know the number of sections that have been scanned or the number of sections that have not been scanned based on the total number of sections. In some optional application scenarios, the specific content of the scanning guidance information is not limited to the above, and can also include other information, such as the name of each section, etc.

[0083] S13, displaying scanning guidance information in the guidance area of ​​the interface.

[0084] Wherein, the interface also includes an image display area for displaying ultrasound images.

[0085] The interface includes a guide area and an image display area. The guide area is used to display scanning guide information, and the image display area is used to display scanning guide information. It should be noted that there is no absolute area division between the guide area and the image display area. There may be overlapping areas between the two, or the guide area is set in the image display area. The guide area and the image display area are explained here only to illustrate the difference in their main display content. The interface layout of the guide area and the image display area is set according to actual needs and is not limited here.

[0086] In some optional implementations, the guide area may be a floating window. The user can adjust the position and size of the floating window through interaction with the floating window to meet the current scanning requirements.

[0087] During the ultrasound scanning process, the scanned ultrasound image is displayed in real time in the image display area, and the user can save the scanned ultrasound image through operation for subsequent viewing. Alternatively, during the scanning process, the ultrasound device automatically identifies the similarity between the ultrasound image of each section and the corresponding standard ultrasound image, and automatically saves the ultrasound image if the similarity requirement is met. Therefore, the storage operation of the ultrasound image of each section can be manual storage or automatic storage; or, manual storage and automatic storage are automatically switched, for example, a time threshold for automatic storage is set. If the ultrasound image scanned within the time threshold does not meet the similarity requirement, the user is prompted to perform manual storage based on experience. If the ultrasound image scanned within the time threshold meets the similarity requirement, the image is automatically saved and switched to the next section for ultrasound scanning.

[0088] Of course, the above examples are merely some optional implementations and do not limit the protection scope of the present invention. The specific application methods are set according to actual scenarios and are not limited here.

[0089] The method for guiding ultrasonic scanning provided in this embodiment corresponds to the scanning protocol of the scanning part and the total number of sections of the scanning part. After determining the target scanning protocol, the scanning guidance information including the part to be scanned and the total number of sections of the scanning part is correspondingly determined. Based on this, the scanning guidance information determined by the target scanning protocol is displayed in the guidance area to give the user scanning guidance, so as to perform a comprehensive scan of the corresponding sections of the part to be scanned, thereby improving the accuracy of ultrasonic scanning.

[0090] In some optional embodiments, the above S13 includes: displaying the target scanning protocol in the first area of ​​the guide area, and displaying the total number of sections of the part to be scanned and the currently scanned section in the second area of ​​the guide area.

[0091] In order to facilitate the description of the function of the guide area, the guide area is divided into a first area and a second area. The first area is used to display the target scanning protocol. For example, Figure 3 As shown, the display content of the first area includes selection protocol ① and eFAST②, selection protocol ① is the description of the currently selected target scanning protocol, and eFAST② is the target scanning protocol. The first area provides a human-computer interaction function, and the user can select the target scanning protocol for the current scan by interacting with the first area.

[0092] The second area is used to display the total number of sections to be scanned and the section currently being scanned, for example, Figure 3 As shown in the figure, "1 / 8 right upper abdomen"④ means that the part to be scanned is the right upper abdomen, the total number of sections is 8 sections, and the section currently scanned is the first section. If the target scanning protocol corresponds to 2 parts to be scanned, then during the scanning, each section of the part to be scanned 1 is scanned, and then each section of the part to be scanned 2 is scanned.

[0093] The guide area also includes a first switching control for switching the current scanned section. Figure 3 As shown, the first switching control includes a leftward triangle ③ and a rightward triangle ⑤. The leftward triangle represents jumping to the previous step. If the current step is the first step, this control is not available. The rightward triangle represents jumping to the next step. If the current step is the last step, this control is not available.

[0094] For example, the target scanning protocol corresponds to the to-be-scanned parts including to-be-scanned parts 1 and to-be-scanned parts 2, the total number of sections of to-be-scanned parts 1 is 3, and the total number of sections of to-be-scanned parts 2 is 2. Then, the first area is displayed in the following ways: 1 / 3 to-be-scanned parts 1->2 / 3 to-be-scanned parts 1->3 / 3 to-be-scanned parts 1->1 / 2 to-be-scanned parts 2->2 / 2 to-be-scanned parts 2. If the current scanned section is: 3 / 3 to-be-scanned parts 1, if you select the left triangle, the current scanned section is switched to 2 / 3 to-be-scanned parts 1. If you select the right triangle, the current scanned section is switched to 1 / 2 to-be-scanned parts 2.

[0095] It should be noted that the scanning order of the to-be-scanned part corresponding to the target scanning protocol and the scanning order of the cross-section corresponding to the to-be-scanned part can be set according to actual needs and are not limited here.

[0096] The currently scanned section and the total number of sections are displayed in the guide area so that the user can intuitively understand the current scanning progress. At the same time, the currently scanned section is switched through the first switching control to scan the next section.

[0097] In some optional embodiments, the guide area also includes a second switching control for switching the section currently being scanned after storing the ultrasound image currently scanned. Specifically, the second switching control includes two functions, one is to store the ultrasound image currently scanned, and the other is to switch the section currently being scanned. For example, continuing with the above example, if the section currently being scanned is 2 / 3 of the part to be scanned 1, the user interacts with the second switching control to store the ultrasound image of 2 / 3 of the part to be scanned 1, and switch to 3 / 3 of the part to be scanned 1 for ultrasound scanning.

[0098] For example, Figure 3 As shown, in the guidance area, "Tip: Click the second switch control button to go to the next step"⑥, Figure 3 The second switch control is represented by a camera. This prompt is used to prompt the user how to execute this workflow. Figure 3 It means that clicking the camera button can automatically save the image and switch to the next step, without the need to freeze and then save the image, saving user time and improving scanning efficiency.

[0099] By interacting with the second switching control, the ultrasound image obtained by the current scan is stored and the current scanned section is switched. Image storage and switching can be achieved through one interaction, which simplifies user operations and improves the efficiency of ultrasound scanning.

[0100] Comparing the difference between the first switching control and the second switching control, the first switching control is used to switch the current section, while the second switching control is used to switch the current section after storing the ultrasound image. Therefore, when the user does not need to store the ultrasound image of the current section, the section can be switched through the first switching control. If the user wants to store the ultrasound image of the current section, the section can be switched through the second switching control.

[0101] In some optional embodiments, the first switching control and the second switching control described above are both used to switch the current section manually. As described above, the current section can be switched by automatic recognition. For example, standard ultrasound images of various sections are stored in the ultrasound device, and the similarity between the collected ultrasound image and the corresponding standard ultrasound image is calculated. If the similarity requirement is met, the ultrasound image of the current section is automatically stored and switched to the next section.

[0102] In some optional embodiments, the method further comprises:

[0103] Step a1, obtaining the section scanning status of the part to be scanned.

[0104] Step a2: Display the section scanning status in the prompt area of ​​the interface.

[0105] The section scanning status includes but is not limited to the section that has been scanned and has stored images, the section that has been scanned but has not stored images, and the section that has not been scanned. When performing ultrasonic scanning on a section, different symbols can be used to indicate different section scanning states. The section scanning status of each section is displayed in the prompt area so that the user can intuitively understand the scanning status of each section and deal with the corresponding problems in a timely manner.

[0106] The prompt area of ​​the interface can be displayed at any position of the interface. It can be an area independent of the image display area and the guide area. The prompt area can also be displayed in the image display area or the guide area, or in an area that partially overlaps, etc. For example, Figure 4 As shown, the prompt area is set in the indication area, or, as shown Figure 5 As shown, the prompt area is set in the image display area. The specific interface layout of the prompt area, image display area and guide area is set according to actual needs and is not limited here.

[0107] As mentioned above, there is a sequential relationship between the parts to be scanned corresponding to the target scanning protocol and the sections to be scanned of the parts to be scanned. The order can be adjusted before scanning. If no adjustment is made, the scan is performed according to the default order. For example, a part to be scanned includes 8 sections to be scanned. The current scan is the 6th section to be scanned. Each section records its section scanning status. If there are unfinished sections in the 1st to 5th scanned sections, the prompt information of the completed section is displayed in the prompt area. Among them, the unfinished sections include sections that have not been scanned or sections that have been scanned but not saved. For the currently scanned section, the section scanning status of the previous sections is queried in turn, so as to give the corresponding prompt information. When performing ultrasonic scanning, there is a corresponding section scanning order for the sections to be scanned. For the sections that have not been completed before the current section, the prompt information is displayed in the prompt area to facilitate the user to handle it in time.

[0108] For example, Figure 6 As shown in the figure, due to the limited interface space, it is impossible to display all sections and their scanning status on one screen. A text description will be added to the guide area to indicate that there are unfinished sections before the current section. Figure 6 What is shown is a form, but it does not limit the protection scope of the present invention, and it is set according to actual needs. And the font color, style, etc. of the text description are also set according to actual needs.

[0109] In some optional implementations, the section scanning order is preset, or the user adjusts the section scanning order by interacting with the interface. After adjusting the section scanning order, the preset order can be restored with one click, etc. The section scanning order can be user-defined to meet the user's scanning habits and improve the user's scanning efficiency.

[0110] In some optional embodiments, the section scanning status is displayed through prompt icons. Among them, the prompt icons correspond one-to-one to the sections of the part to be scanned, and the display mode of the prompt icons corresponds to the corresponding section scanning status. Specifically, if the part to be scanned includes 8 sections to be scanned, 8 prompt icons are displayed, and the display mode of the prompt icons corresponds one-to-one to the section scanning status of the corresponding sections. The scanning status of each section is represented by prompt icons corresponding one-to-one to the sections, and the user can intuitively understand it without performing any operation to view it.

[0111] The prompt icon can be a dot, a square, etc. The display method of the prompt icon includes but is not limited to the icon's fill color, fill line, etc. For example, Figure 7 As shown in the figure, the slice scanning status corresponds to the fill color of the prompt icon, that is, red indicates a slice that has been scanned but not saved, blue indicates a slice that has been scanned and saved, and gray indicates a slice that has not been scanned. Figure 7 In the figure, the third section is the section that has been scanned but not saved, and the fourth section is the section currently being scanned.

[0112] In some optional embodiments, a body shape diagram is displayed in the prompt area, and a prompt icon is displayed in the body shape diagram at the corresponding position of the section to be scanned. For the prompt icon, please refer to the above description and will not be repeated here. The body shape diagram can be a standard body shape diagram, which has nothing to do with the scanned object. After determining the target scanning protocol, the correspondence between the target scanning protocol and the part to be scanned is used to display a preset body shape diagram with a prompt icon in the prompt area, and during the scanning process, as the scanning status of each section changes, the display mode of the prompt icon in the body shape diagram changes accordingly. For example, Figure 4 As shown, the body shape diagram uses a prompt icon to help users see at a glance how many sections to be scanned under the target scanning protocol are needed and their corresponding position information. The prompt icon display method can also tell at a glance which sections have been scanned and which have not been scanned, thereby increasing or decreasing the usability of the ultrasound scanning function.

[0113] For example, Figure 4 The prompt area is displayed in the third area of ​​the guidance area, and Figure 5 The prompt area is displayed separately from the guidance area. Of course, the layout position of the prompt area is not limited to this, and it can be set according to actual needs.

[0114] In some optional implementations, the display style of the guide area can be customized according to user needs, for example, background transparency or brightness, etc. Since each user has different feelings and needs for the amount of information in the image area, some prefer a background with high transparency to reduce its interference with the image area, while others prefer a background with low transparency to ensure that the words can be seen more clearly. The customized setting of the background transparency of the guide area can effectively solve the actual needs of different users in different scenarios, making the use of the application more in line with the needs of users, thereby improving scanning efficiency.

[0115] In some optional embodiments, the method for guiding ultrasound scanning further includes: in response to a selection operation of a target prompt icon in the prompt icon, displaying an ultrasound image corresponding to the target prompt icon or switching to a section corresponding to the target prompt icon for scanning.

[0116] The function of the prompt icon not only includes displaying the scanning status of each section, but also provides an interactive function. The user can switch to the corresponding section for processing by interacting with the prompt icon. Specifically, if the corresponding section has been saved, the ultrasound image of the section will be displayed in the image display area. Of course, the ultrasound image of the section can also be collected again. If the corresponding section has not been saved, the section is scanned to obtain its corresponding ultrasound image.

[0117] The difference between the way of switching sections through prompt icons and the first switching control and the second switching control is that the first switching control and the second switching control can only switch sections according to the scanning order of the sections, while the prompt icons are not limited by the scanning order, which is more convenient for users to switch sections. By selecting the target prompt icon, you can switch to the corresponding ultrasound image or scan the corresponding section, which realizes the direct switching of sections and avoids switching in sequence according to the scanning order of the sections, thereby improving the operation efficiency.

[0118] In some optional embodiments, the method for guiding ultrasound scanning further includes:

[0119] Step b1, obtaining an ultrasonic image of the current section.

[0120] Step b2: If the ultrasound image meets the requirements of the preset ultrasound image, the next section is automatically switched to for scanning according to the scanning order of the section to be scanned.

[0121] After acquiring the ultrasound image of the current section, the ultrasound device calculates the similarity between the ultrasound image and the preset ultrasound image of the section. If the similarity is greater than the threshold, it means that the ultrasound image meets the requirements of the preset ultrasound image. The ultrasound image is then stored and automatically switched to the next section for scanning according to the scanning sequence of the sections to be scanned. The relationship between the acquired ultrasound image and the preset ultrasound image is used to realize automatic switching of ultrasound scanning, further improving the scanning efficiency.

[0122] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
