[0067] An embodiment of the present invention provides an ultrasonic imaging device and an ultrasonic image analysis method for displaying multiple tissue trait parameters of a tissue to be measured in the form of a radar chart, and simultaneously displaying a graded reference chart of the multiple tissue trait parameters around the radar chart, thereby assisting in grading the measurement information of the tissue to be measured.

[0068] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions 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 embodiments described are only 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 ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0069] The terms "first," "second," "third," "fourth," and the like in the specification and claims of the present invention and in the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0070] For ease of understanding, the ultrasonic imaging device in the embodiment of the present application is first described. Figure 1 , the ultrasonic imaging device in the embodiment of the present application includes:

[0071] The ultrasound probe 10 , the transmitting circuit 20 , the receiving circuit 30 , the processor 40 and the display 50 may further include a transmitting / receiving selection switch 60 , a beamforming module 70 and a memory 80 , in addition to the transmitting circuit 20 , the receiving circuit 30 .

[0072] The ultrasonic probe 10 can be any probe used for ultrasonic testing, such as a 2D ultrasonic probe or a 3D ultrasonic probe. The acoustic head portion of the ultrasonic probe 10 can be an array composed of multiple array elements, such as multiple array elements arranged in a row to form a linear array, or arranged in a two-dimensional matrix to form a planar array. Multiple array elements can also form a convex array. The array elements are used to transmit ultrasonic beams based on excitation electrical signals or to convert received ultrasonic echoes into electrical signals. Therefore, each array element can be used to convert electrical pulse signals into ultrasonic beams, thereby transmitting ultrasonic waves to target tissue in the human body, and can also be used to receive echoes of ultrasonic waves reflected from the tissue.

[0073] The transmitting circuit 20 is used to generate a transmitting sequence according to the control of the processor 40, and the transmitting sequence is used to control some or all of the multiple array elements to transmit ultrasonic waves to biological tissue.

[0074] The receiving circuit 30 is used to receive the electrical signal of the ultrasonic echo from the ultrasonic probe 10 , obtain the ultrasonic echo signal, and send the ultrasonic echo signal to the beamforming module 70 .

[0075] Beamforming module 70 is used to perform delay, weighted summation, and beamforming on the signals output by receiving circuit 30. Because the distances between ultrasound receiving points and receiving elements in the tissue being measured vary, the channel data from the same receiving point output by different receiving elements have different delays. This requires delay processing, phase alignment, and weighted summation of the different channel data from the same receiving point to generate beamformed data.

[0076] Processor 40 is connected to beamforming module 70 and primarily performs detection, signal enhancement, data conversion, and logarithmic compression on the beamformed data to form an ultrasound image. The ultrasound image obtained by processor 40 can be displayed on display 50 or stored in memory 80.

[0077] Optionally, the processor 40 may be at least one of an application-specific integrated circuit (ASIC), a digital signal processor (DSP), a digital signal processing device (DSPD), a programmable logic device (PLD), a field programmable gate array (FPGA), a central processing unit (CPU), a controller, a microcontroller, or a microprocessor, so that the processor 40 can control other components in the ultrasonic imaging device to perform the ultrasonic imaging steps in various embodiments of this specification. The processor 40 may be a component or a general term for a control device and a processing device in the ultrasonic imaging device that can control other components of the ultrasonic imaging device to perform various functions in various embodiments.

[0078] The display 50 is connected to the processor 40. The display 50 may be a touch screen display or a liquid crystal display, etc. Alternatively, the display 40 may be an independent display such as a liquid crystal display or a television set that is independent of the ultrasound imaging device. Alternatively, the display 40 may be a display screen of an electronic device such as a smartphone or a tablet computer, etc. The number of displays 40 may be one or more.

[0079] In addition to the above structure, the ultrasonic imaging device may also include a human-computer interaction device. Specifically, the human-computer interaction device may be a display 40. If all the functions of the human-computer interaction device are integrated into the display 40, the display 40 may also provide the user with a graphical interface for human-computer interaction when displaying the ultrasonic image. One or more controlled objects are set on the graphical interface, and the user is provided with a way to input operation instructions using the human-computer interaction device 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 using the human-computer interaction device to perform a specific function, such as enlarging the characteristic area in the radar map or displaying the quality control results of tissue property parameters in the ultrasonic image of the tissue property parameters.

[0080] The human-computer interaction device may also be another human-computer interaction device other than the display 40. For example, the human-computer interaction device may include an input device for detecting user input information, which may be, for example, instructions for editing and marking ultrasound images, or may include other types of instructions. The input device may include one or a combination of a keyboard, a scroll wheel, a trackball, a mobile input device (such as a mobile device with a touch screen display, a mobile phone, etc.), a multi-function knob, etc. The human-computer interaction device may also include an output device such as a printer.

[0081] The ultrasonic imaging device may further include a memory 80 for storing instructions for processing, storing received ultrasonic echo signals, storing ultrasonic image data, and the like. The memory 80 may be a volatile memory, such as a random access memory (RAM), or a non-volatile memory, such as a read-only memory (ROM), flash memory, a hard disk drive (HDD), or a solid-state drive (SSD), or a combination of these types of memory, and provides instructions and data to the processor.

[0082] It should be understood that Figure 1 The components included in the ultrasonic imaging device shown are only exemplary, and the device may include more or fewer components, and the present application does not impose corresponding limitations on this.

[0083] Based on the existing technology, when grading the measurement information of the tissue to be measured by combining multiple tissue property parameters, only the multiple tissue property parameters are displayed simultaneously on the operation interface. However, due to the diversity and complexity of the quantitative parameters and quantitative evaluation indicators when the multiple tissue property parameters provide multi-dimensional quantitative evaluation, the conventional listing method makes it difficult for doctors to obtain the grading information of the tissue to be measured. The embodiment of the present application provides an ultrasonic imaging device for simultaneously displaying a radar chart drawn by multiple tissue property parameters and a grading reference chart of multiple tissue property parameters in the operation interface, thereby assisting the user in grading the measurement information of the tissue to be measured according to the multiple tissue property parameters.

[0084] The following is a detailed description of the first embodiment of the ultrasonic imaging device in the embodiments of the present application:

[0085] Specifically, the transmitting circuit 20 in the ultrasonic imaging device in the embodiment of the present application is used to stimulate the ultrasonic probe 10 to transmit ultrasonic waves toward the tissue area to be measured of the subject, the receiving circuit 30 is used to control the ultrasonic probe 10 to receive ultrasonic echoes returned from the tissue area to be measured to obtain ultrasonic echo signals, and the processor 40 is used to:

[0086] Acquiring an ultrasound image obtained by ultrasonically scanning a tissue to be tested, determining a region of interest in the ultrasound image, and in response to a triggering operation of a multi-parameter joint analysis, acquiring at least three tissue property parameters of the region of interest, wherein the at least three tissue property parameters include at least three of a shear wave elasticity parameter, a shear wave viscosity parameter, a dispersion parameter, an acoustic attenuation parameter, a sound velocity, and a liver texture parameter; and acquiring a graded reference map corresponding to each of the at least three tissue property parameters, wherein the graded reference map corresponding to the tissue property parameter displays a graded display feature and a reference unit value, wherein the graded display feature is used to distinguish graded levels corresponding to the values of the tissue property parameter, and the reference unit value is used to divide the graded levels;

[0087] generating a radar chart using the at least three tissue property parameters as classification axes, determining position points corresponding to the values of the respective tissue property parameters on the classification axes of the radar chart according to the reference unit values, and connecting the position points to form a characteristic region;

[0088] Display 50: used to display the at least three tissue property parameter grading reference graphs, radar graphs and characteristic areas.

[0089] For ease of understanding, Figure 2 A schematic diagram of an ultrasound image and a region of interest is given, where Figure 2 The box in the figure is a schematic diagram of the region of interest. When determining the region of interest in the ultrasound image, the region of interest may be manually defined by the user, or the processor may automatically determine the region of interest in the ultrasound image based on a preset algorithm. There is no specific limitation on the method of determining the region of interest.

[0090] Furthermore, when triggering the multi-parameter joint analysis, it can be triggered based on the trigger button in the operation page, or based on the hardware in the human-computer interaction device, and no specific restrictions are made here. The processor 40 responds to the trigger operation of the multi-parameter joint analysis to obtain at least three tissue property parameters of the area of interest, wherein the at least three tissue property parameters include at least three of shear wave elasticity parameters, shear wave viscosity parameters, dispersion parameters, acoustic attenuation parameters, sound speed and liver texture parameters, wherein the types of the at least three tissue property parameters mainly depend on the type of tissue to be tested and the type of disease, and no specific restrictions are made here on the types of the at least three tissue property parameters.

[0091] The tissue characteristic parameter grading reference chart is used to grade tissue characteristic parameters according to their values. For ease of understanding, Figure 3 A schematic diagram of a graded reference diagram of three tissue property parameters is provided, wherein the graded reference diagram of the tissue property parameters displays graded display features and reference unit values. The graded display features are used to distinguish the graded levels corresponding to the values of the tissue property parameters, and the reference unit values are used to divide the graded levels. If the values of the tissue property parameters represented by the reference unit values are different in size, the same value of the same tissue property parameter will be divided into different classification levels, and the reference unit values can also determine the position points of the tissue property parameter values on the classification axis. If the values of the tissue property parameters represented by the unit length on the classification axis are different, the position points of the tissue property parameters determined on the classification axis will also be different.

[0092] Of course, when displaying the graded reference graph, it can be Figure 3 The grading information can be identified by the colors (different grayscales) in the image, or can be given in the form of line type, pattern fill or characters. There is no specific restriction on the external form of the grading reference diagram of the tissue property parameters.

[0093] Furthermore, the processor 40 generates a radar chart based on the values of at least three tissue property parameters and the reference unit values in the graded reference chart of the at least three tissue property parameters, using the at least three tissue property parameters as classification axes, determines position points corresponding to the values of each tissue property parameter on the classification axis of the radar chart based on the reference unit values, and connects the position points to form a characteristic region, wherein the characteristic region is used to characterize different values of the at least three tissue property parameters. For ease of understanding, Figure 4 A schematic diagram of a radar chart with shear wave elastic parameters, shear wave viscosity parameters and acoustic attenuation parameters as classification axes is given.

[0094] In order to facilitate the user to obtain the graded information of the measurement information of the tissue to be measured, the embodiment of the present application also displays a graded reference map, a radar map and a characteristic area of at least three tissue property parameters through the display 50.

[0095] Because the hierarchical display features and reference unit values of different levels are displayed in the hierarchical reference diagram corresponding to the tissue property parameters in the embodiment of the present application, the user can judge the hierarchical information of each tissue property parameter through the position point of each tissue property parameter in the radar diagram, and then obtain the comprehensive hierarchical information of the region of interest of the tissue to be measured based on the hierarchical information of each tissue property parameter, thereby improving the convenience of the user in grading the measurement information of the region of interest of the tissue to be measured based on multiple tissue property parameters.

[0096] Based on the first embodiment of the ultrasonic imaging device, when assisting a user in grading a tissue to be measured, in order to further enhance the convenience for the user in obtaining a grading result of a region of interest in the tissue to be measured, the processor 40 in the embodiment of the present application may further perform the following steps:

[0097] The characteristic regions in the radar map are graded to obtain a classification result of the characteristic regions.

[0098] The process of automatically grading the characteristic regions by the processor 40 improves the convenience for the user to obtain the graded information of the disease course of the tissue to be measured.

[0099] Next, a second embodiment of the ultrasonic imaging device in the embodiments of the present application is described:

[0100] Specifically, the transmitting circuit 20 in the ultrasonic imaging device in the embodiment of the present application is used to stimulate the ultrasonic probe 10 to transmit ultrasonic waves toward the tissue area to be measured of the subject, the receiving circuit 30 is used to control the ultrasonic probe 10 to receive ultrasonic echoes returned from the tissue area to be measured to obtain ultrasonic echo signals, and the processor 40 is used to:

[0101] Acquiring an ultrasound image obtained by ultrasonically scanning a tissue to be tested; determining a region of interest in the ultrasound image; obtaining at least three tissue property parameters of the region of interest in response to a triggering operation of a multi-parameter joint analysis; generating a radar chart using the at least three tissue property parameters as classification axes; obtaining grading reference standards corresponding to the at least three tissue property parameters, and determining position points corresponding to the values of each tissue property parameter on the classification axis of the radar chart based on the grading reference standards to obtain a characteristic region formed by connecting each of the position points; and calculating a quantitative parameter of the characteristic region based on the formed characteristic region to indicate the lesion properties of the tissue to be tested;

[0102] Specifically, the at least three tissue property parameters in the embodiment of the present application include at least three of shear wave elasticity parameters, shear wave viscosity parameters, dispersion parameters, acoustic attenuation parameters, sound velocity and liver texture parameters, and the method for determining the region of interest and the triggering operation of multi-parameter joint analysis are similar to those described in the above embodiments and will not be repeated here.

[0103] The display 50 is used to:

[0104] Displays quantitative parameters of the feature area.

[0105] In an embodiment of the present application, the quantitative parameters of the characteristic area can be directly displayed on the display interface, and the quantitative parameters are used to indicate the lesion properties of the tissue to be tested, thereby improving the convenience for users to obtain the lesion properties of the tissue to be tested.

[0106] Based on the second embodiment of the ultrasonic imaging device, in order to make it easier to view the grading reference standards, a grading reference map of the corresponding tissue trait parameters can be further generated based on the grading reference standards of each tissue trait parameter, wherein the grading characteristics and reference unit values are displayed in the grading reference map of the tissue trait parameters, wherein the grading display characteristics are used to distinguish the grading levels corresponding to the tissue trait parameter values, and the reference unit values are used to divide the grading levels.

[0107] The hierarchical display feature may be at least one of color, line type, or fill pattern.

[0108] The quantitative parameters of the characteristic region include at least one of the area of the characteristic region, the perimeter of the characteristic region, the number of pixels contained in the characteristic region, and a comparison result between the characteristic region and a preset region.

[0109] Furthermore, the comparison results between the feature area and the preset area include: the ratio of the area and / or perimeter of the feature area to the area and / or perimeter of each graded area in the graded reference map, or the ratio of the side length of the feature area to the side length of each graded area in the graded reference map, or the ratio of the distance from the vertex to the center of the feature area to the distance from the vertex to the center of each graded area in the graded reference map. The calculation process of the above-mentioned ratios will be described in the following embodiments and will not be repeated here.

[0110] The embodiment of the present application can directly obtain the parameters of the feature area based on at least one of the area of the feature area, the perimeter of the feature area, the number of pixels contained in the feature area, and the comparison result between the feature area and the preset area, thereby improving the convenience of obtaining the parameters of the feature area.

[0111] Based on the second embodiment of the ultrasonic imaging device, after obtaining the quantitative parameters of the characteristic region, the quantitative parameters of the characteristic region can also be graded to obtain a grading result of the characteristic region, and the grading result is used to characterize the level of the lesion attribute of the tissue to be tested.

[0112] In order to facilitate the user to view the classification results of the feature areas, the display 50 can also:

[0113] The classification result of the feature area is displayed with a preset display feature, wherein the preset display feature includes at least one of a character, a color, a line type, and a fill pattern.

[0114] For example, a prompt may be directly displayed in text on the interface: the feature area is between level C and level D; the grading result of the feature area may be displayed in a color corresponding to the level (such as orange); or the grading result of the feature area may be displayed in a line type corresponding to the level (such as a double dashed line); or the grading result of the feature area may be displayed in a filling pattern corresponding to the level (such as a cross grid). Of course, the above examples are only explanations of the display features, not limitations.

[0115] Furthermore, in addition to displaying the parameters of the characteristic area and the grading results of the characteristic area on the display interface, in order to facilitate the user to check the grading standards, the grading reference map, radar map and characteristic area corresponding to at least three tissue trait parameters can also be displayed on the display interface.

[0116] The method of simultaneously displaying quantitative parameters, grading results of characteristic areas, grading reference maps corresponding to at least three tissue trait parameters, radar maps and characteristic areas on the display interface improves the convenience of users in checking the grading standards when viewing the grading results of characteristic areas.

[0117] Specifically, the classification process of the feature regions will be described in the following embodiments and will not be repeated here.

[0118] Based on the first and second embodiments of the ultrasonic imaging device, when acquiring at least three tissue property parameters, the processor 40 may further acquire ultrasonic images of at least three tissue property parameters, and control the display 50 to display the ultrasonic images of at least three tissue property parameters, and simultaneously display the tissue property parameters (including parameter identifiers and parameter values) around the ultrasonic images of the tissue property parameters. Furthermore, after generating the radar chart, the processor 40 may further display the ultrasonic images of at least three tissue property parameters, at least three tissue property parameters (including parameter identifiers and parameter values), at least three tissue property parameter grading reference maps, the radar chart, and the characteristic areas in the display interface (i.e., the interface displaying the ultrasonic images of at least three tissue property parameters). Of course, after obtaining the grading results of the characteristic areas, the grading results of the characteristic areas may also be displayed in the interface. For ease of understanding, Figure 5 A schematic diagram of an interface showing an ultrasound image of at least three tissue property parameters, at least three tissue property parameters (including parameter identifiers and parameter values), at least three tissue property parameter grading reference graphs, a radar graph, and characteristic regions in the same display interface is provided;

[0119] Alternatively, it is also possible to display at least three ultrasound images of tissue property parameters and at least three tissue property parameters (including parameter identifiers and parameter values) in the first display interface, and display at least three tissue property parameter grading reference graphs, radar graphs and characteristic areas in the second display interface. Of course, after obtaining the grading results of the characteristic areas, the grading results of the characteristic areas can also be displayed in the second display interface, that is, the above images are displayed separately to improve the simplicity of the display interface and facilitate understanding. Figure 6 A schematic diagram of the first display interface and the second display interface is given.

[0120] Based on the first and second embodiments of the ultrasonic imaging apparatus, when the processor 40 obtains the grading reference images corresponding to at least three tissue property parameters, because the values of the tissue property parameters measured by the ultrasonic imaging apparatus of each manufacturer for the same morphology of the measured tissue are slightly different, different grading thresholds and corresponding grading display features can be set for each tissue property parameter for the ultrasonic imaging apparatus of different manufacturers, wherein the grading display features include at least one of color, line type, or fill pattern. For ease of understanding, Figure 7 A schematic diagram of an operation interface for setting at least three tissue trait parameter grading thresholds is given.

[0121] Based on the first embodiment and the second embodiment of the ultrasonic imaging device, the processor 40 may obtain at least three tissue property parameters in different ways:

[0122] As an optional embodiment, the processor 40 excites the ultrasonic probe 10 through the transmitting circuit 20 to send an excitation pulse to the region of interest to generate a shear wave in the region of interest, excites the ultrasonic probe 10 through the transmitting circuit 20 to transmit an ultrasonic wave that tracks the shear wave to the region of interest, controls the ultrasonic probe 10 through the receiving circuit 30 to receive the echo of the ultrasonic wave to obtain an ultrasonic echo signal, and then processes the ultrasonic echo signal to obtain at least three tissue property parameters of the region of interest.

[0123] Because the embodiment of the present application can transmit the excitation pulse and track the shear wave of the ultrasound in real time, so that the ultrasound echo signal received by the receiving circuit 20 is based on the echo signal of the same ultrasound, it can be considered that the echo signal of the same ultrasound is based on the ultrasound echo signal of the same section. Therefore, after processing the ultrasound echo signal, the at least three tissue property parameters of the area of interest obtained are also at least three tissue property parameters of the same section, thereby ensuring the accuracy of the measurement of the above-mentioned at least three tissue property parameters.

[0124] Furthermore, the above embodiments also share the same ultrasonic echo signal to obtain at least three tissue property parameters of the region of interest in the tissue to be measured, that is, at least three tissue property parameters of the region of interest can be calculated through the same ultrasonic echo signal, thereby improving the convenience of obtaining the above-mentioned tissue property parameters.

[0125] As another optional embodiment, the processor 40 excites the ultrasonic probe 10 through the transmitting circuit 20 to send a first excitation pulse to the region of interest to generate a shear wave in the region of interest, and excites the ultrasonic probe 10 through the transmitting circuit 20 to transmit a first ultrasonic wave that tracks the shear wave to the region of interest; controls the ultrasonic probe 10 through the receiving circuit 30 to receive the echo of the first ultrasonic wave to obtain a first ultrasonic echo signal; and processes the first ultrasonic echo signal to obtain a part of the at least three tissue property parameters of the region of interest, such as shear wave elasticity parameters, shear wave viscosity parameters and dispersion parameters.

[0126] Furthermore, the processor 40 stimulates the ultrasonic probe 10 to send a second ultrasonic wave to the region of interest through the transmitting circuit 20, wherein the second ultrasonic wave and the first ultrasonic wave are alternately transmitted by the transmitting circuit 20, and the ultrasonic probe 10 is controlled by the receiving circuit 30 to receive the echo of the second ultrasonic wave to obtain a second ultrasonic wave echo signal; the second ultrasonic wave echo signal is processed to obtain another part of the at least three tissue property parameters of the region of interest, such as the acoustic attenuation parameter.

[0127] Specifically, because the shear wave elastic parameters, the shear wave viscosity parameters and the dispersion parameters are all associated with the shear wave signal, the shear wave information can be obtained through the first ultrasonic echo signal, and the shear wave information is further processed to obtain the shear wave elastic parameters, the shear wave viscosity parameters and the dispersion parameters associated with the shear wave signal.

[0128] However, the acoustic attenuation parameter is not associated with the shear wave signal. Therefore, the embodiment of the present application sends a second ultrasonic wave to the region of interest through the transmitting circuit 20, receives the echo signal of the second ultrasonic wave through the receiving circuit 30, and further processes the ultrasonic echo signal to obtain the acoustic attenuation parameter of the region of interest.

[0129] In order to realize that the shear wave elastic parameters, shear wave viscosity parameters and dispersion parameters, as well as the acoustic attenuation parameters are tissue parameters under the same section, the embodiment of the present application transmits the first ultrasonic wave and the second ultrasonic wave in an alternating manner, and because the propagation speed of the ultrasonic wave is very fast, it can be considered that the first ultrasonic echo signal and the second ultrasonic echo signal are also ultrasonic echo signals under the same section.

[0130] Furthermore, the embodiments of the present application emit ultrasonic waves that match different types of tissue property parameters, such as emitting a first ultrasonic wave for shear wave elastic parameters, shear wave viscosity parameters, and dispersion parameters, and emitting a second ultrasonic wave for acoustic attenuation parameters. This further improves the accuracy of calculating tissue property parameters based on ultrasonic echo signals compared to the method of calculating tissue property parameters using non-matching types of ultrasonic echo signals.

[0131] Based on the first and second embodiments of the ultrasonic imaging device, when the processor 40 obtains the target tissue characteristic parameter among at least three tissue characteristic parameters (the target tissue characteristic parameter is any one of the at least three tissue characteristic parameters), in order to further improve the accuracy of obtaining the target tissue characteristic parameter value, the preset value among the at least three target tissue characteristic parameters can also be used as the final value of the target tissue characteristic parameter, wherein the preset value can be the average value, median value, maximum value or minimum value among multiple target tissue characteristic parameter values. There is no specific restriction on the type of the preset value here, and the type of the preset value can also be selected according to the specific measurement scenario.

[0132] Based on the first embodiment and the second embodiment of the ultrasonic imaging device, the following describes the selection of at least three tissue property parameters and the display method of the at least three tissue property parameters:

[0133] Specifically, the embodiment of the present application can receive the selected at least three tissue property parameters and measurement methods (the measurement methods include focal measurement methods and diffuse measurement methods) through the operation page, wherein the selected at least three tissue property parameters are displayed in a preset area of the operation page in a first display order. In order to facilitate the user to view the ultrasound image corresponding to the target tissue property parameter, the embodiment of the present application can also display the ultrasound images of the at least three tissue property parameters in the first display order at the position corresponding to the tissue property parameter on the operation page based on the selected at least three tissue property parameters. For ease of understanding, Figure 8 A schematic diagram of the operation interface for selecting at least three tissue characteristic parameters is given. Figure 9 Given the corresponding Figure 8 Schematic diagram of the display interface of an ultrasound image of at least three tissue property parameters.

[0134] The following details:

[0135] As in Figure 8 In the operation page, the multi-tissue characteristic parameters that can be jointly selected include B (grayscale parameter), STE (shear wave elasticity), STVi (shear wave viscoelasticity, including shear wave viscosity and dispersion parameters), USAT (acoustic attenuation parameter), TSSSI (sound velocity) and LTI (liver texture parameter). If the multi-tissue characteristic parameters selected by the user include B (grayscale parameter), STE (shear wave elasticity), STVi (shear wave viscoelasticity, including shear wave viscosity and dispersion parameters), USAT (acoustic attenuation parameter), then the corresponding Figure 9When the operation interface of Figure a displays the ultrasound images of the above four parameters, the ultrasound images corresponding to the above tissue parameters are displayed at the corresponding display positions in accordance with the display sequence of B (grayscale parameter), STE (shear wave elasticity), STVi (shear wave viscoelasticity, including shear wave viscosity and dispersion parameters), and USAT (acoustic attenuation parameter). If the multiple tissue characteristic parameters selected by the user include B (grayscale parameter), STE (shear wave elasticity), and STVi (shear wave viscoelasticity, including shear wave viscosity and dispersion parameters), then the corresponding Figure 9 When the above three parameters are displayed on the operation interface of Figure b, the ultrasound images corresponding to the above tissue property parameters are displayed at the corresponding display positions in the display sequence of B (grayscale parameter), STE (shear wave elasticity), and STVi (shear wave viscoelasticity, including shear wave viscosity and dispersion parameters).

[0136] This method of comparing and displaying tissue property parameters and ultrasound images of the tissue property parameters at corresponding positions also improves the convenience for users to compare various tissue property parameters and ultrasound images of the tissue property parameters.

[0137] In order to further enhance the convenience for users to compare various tissue characteristic parameters with ultrasound images of various tissue characteristic parameters, it is also possible to Figure 10 As shown, each tissue property parameter and the ultrasound image of each tissue property parameter are displayed on the same screen, thereby further improving the convenience of comparing each tissue property parameter and the ultrasound image of each tissue property parameter.

[0138] Because measurement errors often occur in the process of measuring each tissue property parameter, the embodiment of the present application can also control the display 50 to display the quality control result image of the tissue property parameter value in response to the trigger operation of obtaining the tissue property parameter quality control result when displaying the tissue property parameter value.

[0139] Specifically, if it is necessary to display the quality control result image of a single tissue property parameter, then in response to the trigger operation of obtaining the quality control result of the tissue property parameter, the ultrasound image of the tissue property parameter measurement value and the quality control result image of the corresponding measurement value are displayed on the same screen. If it is necessary to display the quality control result images of multiple tissue property parameters, then the quality control result images of multiple tissue property parameters can be displayed on the same screen without displaying the ultrasound image of the corresponding tissue property parameter measurement value, such as Figure 11 The quality control result images of grayscale parameters and USAT (acoustic attenuation parameters) are displayed on the same screen.

[0140] The following describes the classification process of the feature regions by the processor 40 in the first and second embodiments of the ultrasonic imaging apparatus:

[0141] As an optional embodiment, the processor 40 may be configured to grade each tissue property parameter according to a grading reference map of the at least three tissue property parameters to obtain a grading result for each tissue property parameter; and then further grade the characteristic region according to the grading result of each tissue property parameter to obtain a grading result for the characteristic region, wherein the grading result of the characteristic region is used to characterize the grading result of the measurement information of the region of interest in the tissue to be measured.

[0142] As another optional embodiment, a base map may also be displayed in the radar chart generated using at least three tissue property parameters as classification axes, wherein the classification axes extend from the center of the base map to the edge of the base map.

[0143] Furthermore, in order to facilitate the classification of the characteristic maps in the radar map, the base map can also be set to multiple concentric circles or multiple concentric polygons, wherein each concentric circle or concentric polygon corresponds one-to-one to the classification level divided in the classification reference map corresponding to the tissue trait parameter. For ease of understanding, Figure 12 The schematic diagrams of radar charts including the graded reference charts corresponding to the six tissue trait parameters are given respectively. Figure 12 The graded reference diagram of the six tissue characteristic parameters in Figure a is displayed in the form of concentric circles, while Figure 12 The grading reference diagram of the six tissue trait parameters in Figure b is displayed in the form of concentric polygons, where the grading threshold of each tissue trait parameter is marked in Figure a, while the grading threshold of each tissue trait parameter is not marked in Figure b.

[0144] The following continues to describe the classification process of the feature map:

[0145] As an optional example, the area and / or perimeter of the characteristic region can be calculated accordingly, and then the area and / or perimeter of the partition corresponding to each grading level in the grading reference diagram of multiple tissue property parameters can be calculated, and then the area of the characteristic region can be compared with the area and / or perimeter of the multiple partitions, and then the grading result of the characteristic region can be determined based on the comparison result.

[0146] Specifically in Figure 13 In Figure a, the area and / or perimeter of the characteristic region are calculated, and then the area and / or perimeter of the circle corresponding to each grading level in the grading reference diagram of multiple tissue property parameters are calculated. Then, the area of the characteristic region is compared with the areas and / or perimeters of the multiple circles, and then the grading result of the characteristic region is determined based on the comparison result.

[0147] For example, when the area of the feature region is between Figure 13If the grading result of the region of interest is between grade C and grade D in Figure a, it is determined that the grading result of the region of interest is between grade C and grade D.

[0148] Specifically in Figure 13 In Figure b, the area and / or perimeter of the characteristic region are calculated, and then the area and / or perimeter of the polygons corresponding to each grading level in the grading reference diagram of multiple tissue characteristic parameters are calculated. Then, the area of the characteristic region is compared with the areas and / or perimeters of the multiple polygons, and then the grading result of the characteristic region is determined based on the comparison result.

[0149] For example, when the area of the feature region is between Figure 13 If the grading result of the region of interest is between grade D and grade E in Figure b, it is determined that the grading result of the region of interest is between grade D and grade E.

[0150] As another optional embodiment, it is also possible to calculate the multiple side lengths of the figure formed by the feature area or the distances from each vertex of the figure formed by the feature area to the center of the feature area; in the base map, calculate the multiple side lengths of the figure formed by each partition corresponding to each level or the distances from each vertex of the figure formed by each partition to the center of the feature area; compare the multiple side lengths of the figure formed by the feature area or the distances from each vertex of the figure formed by the feature area to the center of the feature area with the multiple side lengths of the figure formed by each partition in the multiple partitions or the distances from each vertex of the figure formed by each partition to the center of the feature area; and determine the grading result of the feature area based on the comparison result.

[0151] Specifically in Figure 14 In Figure a, the lengths of each side of the figure formed by the feature area are calculated, and then the multiple side lengths of the figure formed by the feature area are compared with the multiple side lengths of the circumscribed regular polygon of the circle corresponding to each level (wherein the number of side lengths of the circumscribed regular polygon of the circle corresponds to the number of side lengths of the figure formed by the feature area. For example, if the feature area is a hexagon, the circumscribed regular polygon of the circle is the circumscribed regular hexagon). Then, based on the comparison results, the classification result of the feature area is determined, as shown in Figure 14 In Figure a, if during the comparison process, the lengths of the sides of the figure formed by the feature area are greater than 3 of the lengths of the side of the regular polygon of grade C, then the probability that the feature area is classified as grade C is 3 / 6=0.5. If the lengths of the sides of the figure formed by the feature area are greater than 5 of the lengths of the side of the regular polygon of grade D, then the probability that the feature area is classified as grade D is 5 / 6=0.833.

[0152] And in Figure 14In Figure b, the side lengths of the figure formed by the feature area are compared with the side lengths of the polygons corresponding to each grade. If, during the comparison process, the number of side lengths of the figure formed by the feature area that is greater than the side lengths of the C-grade polygon is 3, then the probability that the feature area is graded as C is 3 / 6=0.5. If the number of side lengths of the figure formed by the feature area that is greater than the side lengths of the D-grade polygon is 5, then the probability that the feature area is graded as D is 5 / 6=0.833.

[0153] Of course, in addition to comparing the side lengths, you can also calculate the distances from each vertex of the figure formed by the feature area to the center of the feature area, calculate the distances from each vertex of the figure formed by each partition corresponding to each level to the center of the feature area in the base map, and then compare them. Based on the comparison results, you can get the grading results of the feature area.

[0154] Specifically in Figure 15 In the above, the distance d from each vertex of the figure formed by the feature area to the center of the feature area is calculated, and then the distance d from each vertex of the figure formed by the feature area to the center of the feature area is compared with the distance D from each vertex to the center of the circumscribed regular polygon of the circle corresponding to each level (or the distance from each vertex to the center of the regular polygon corresponding to each level). Then, according to the comparison result, the classification result of the feature area is determined, as shown in Figure 15 In the comparison process, if, during the comparison process, the distances from each vertex of the figure formed by the feature area to the center of the feature area are greater than the number of distances from the vertices to the center of the C-level regular polygon, which is 3, then the probability that the feature area is classified as C-level is 3 / 6=0.5. If the distances from each vertex of the figure formed by the feature area to the center of the feature area are greater than the number of distances from the vertices to the center of the D-level regular polygon, which is 5, then the probability that the feature area is classified as D-level is 5 / 6=0.833.

[0155] In an embodiment of the present application, the area, perimeter, side length or distance from the vertex to the center of the feature area can be compared with the area, perimeter, side length or distance from the vertex to the center of multiple graded areas in the base map, and the graded result of the feature area can be determined based on the comparison result, thereby improving the convenience of determining the graded result of the feature area.

[0156] Further, based on the first embodiment of the ultrasonic imaging device, after the processor 40 completes the automatic grading of the feature area, it controls the display 50 to display multiple tissue property parameter grading reference maps, the radar map and the grading results of the feature area, wherein the grading results of the feature area are used to characterize the grading results of the measurement information of the region of interest.

[0157] Specifically, when displaying the classification results of the feature area, in order to facilitate the user to identify the classification results, the classification results of the feature area can also be displayed using preset display features, wherein the preset display features include at least one of characters, colors, line types and fill patterns. In order to facilitate understanding, Figure 16 A schematic diagram of an interface showing multiple tissue property parameter grading reference maps, the radar map and the grading results of characteristic regions is provided. Of course, the values of multiple tissue property parameters of the region of interest can also be displayed in the display interface.

[0158] To further facilitate the user in obtaining a measurement report of the tissue property parameters of the tissue to be measured, the processor 40 can also receive the triggered grading result export operation, and export the grading result of the feature area and at least one of the following: the values of multiple tissue property parameters of the area of interest in the tissue to be measured, the radar chart, and the multiple tissue property parameter grading reference charts.

[0159] In an embodiment of the present application, when displaying the grading results of the feature area, the grading results can be displayed using preset display features, wherein the preset display features include at least one of characters, colors, line types, and fill patterns, thereby further improving the convenience for users to view the grading results of the feature area.

[0160] In addition, users can also directly export the grading results of the feature area and at least one of the following through the grading result export operation: multiple tissue property parameters of the tissue area to be tested, the radar chart, and the multiple tissue property parameter grading reference charts, thereby improving the convenience of users in obtaining grading result reports.

[0161] The ultrasonic imaging device in the embodiment of the present application is described in detail above. Next, the ultrasonic image analysis method in the embodiment of the present application is described. Figure 17 , Figure 17 The first embodiment of the ultrasound image analysis method is as follows:

[0162] 1701. Acquire an ultrasonic image obtained by ultrasonically scanning the tissue to be tested;

[0166] 1705. Generate a radar chart using the at least three tissue property parameters as classification axes, determine position points corresponding to the values of each tissue property parameter on the classification axes of the radar chart according to the reference unit values, and connect the position points to form a characteristic region;

[0167] 1706. Display the graded reference graph, the radar graph, and the characteristic regions corresponding to the at least three tissue property parameters.

Please refer to the corresponding description in the ultrasonic imaging device and will not be repeated here.
