Fig. 1 shows a schematic structural diagram of an ultrasonic medical detection apparatus 100 in an embodiment, and a specific structure is as follows. The ultrasonic medical inspection apparatus 100 shown in fig. 1 mainly includes: a probe 101, a transmission circuit 103, a transmission/reception selection switch 102, a reception circuit 104, a beam forming module 105, a signal processing module 116, and an image processing module 126. In the ultrasound imaging process, the transmission circuit 103 transmits a delay-focused transmission pulse having a certain amplitude and polarity to the probe 101 through the transmission/reception selection switch 102. The probe 101 is excited by the transmission pulse, transmits an ultrasonic wave (which may be any one of a plane wave, a focused wave, or a divergent wave) to a detection object (for example, an organ, a tissue, a blood vessel, etc. in a human body or an animal body, not shown in the figure), receives an ultrasonic echo reflected from a target region with information of the detection object after a certain delay, and converts the ultrasonic echo back into an electric signal again. The receiving circuit 104 receives the electric signals generated by the conversion of the probe 101, obtains ultrasonic echo signals, and sends the ultrasonic echo signals to the beam forming module 105. The beam forming module 105 performs focusing delay, weighting, channel summation and other processing on the ultrasonic echo signal, and then sends the ultrasonic echo signal to the signal processing module 116 for related signal processing. The ultrasonic echo signals processed by the signal processing module 116 are sent to the image processing module 126. The image processing module 126 performs different processing on the signals according to different imaging modes required by a user to obtain ultrasound image data of different modes, and then performs processing such as logarithmic compression, dynamic range adjustment, digital scan conversion, and the like to form ultrasound images of different modes, such as a B image, a C image, a D image, and the like, or other types of two-dimensional ultrasound images or three-dimensional ultrasound images. The transmitting circuit and the receiving circuit excite the probe to transmit ultrasonic beams to the detection object according to the setting of the ultrasonic imaging parameters, and receive the echoes of the ultrasonic beams to obtain ultrasonic echo signals, so that expected ultrasonic image data is obtained for displaying and showing the tissue structure in the detection object. The ultrasound imaging parameters referred to herein relate to all parameters that are available for the user to autonomously select during the imaging of the ultrasound tissue image, such as TGC (Time Gain compensation), sonic frequency, Pulse Repetition Frequency (PRF), ultrasound type, and dynamic range, among others. In one embodiment, the ultrasound imaging parameters of the ultrasound imaging system include at least one discrete ultrasound imaging parameter, that is, the parameters are not continuously variable but are divided into a plurality of levels or gears, and a certain interval exists between the levels or gears. These parameters will only take values at these levels and gears when adjusted, and values between these levels or gears will not. These parameters of discrete variation are referred to herein as discrete quantities or discrete values that will form discrete alternatives on the graphical user interface. In some embodiments of the present invention, the signal processing module 116 and the image processing module 126 in fig. 1 may be integrated on one main board 106, or one or more (including the same numbers) of the modules may be integrated on one processor/controller chip.

The obtained ultrasound image may be output to the first touch screen 130 for display. The first touch display screen 130 is connected with the image processing module through an input/output interface (the input/output interface can be implemented by wired communication or wireless communication) to implement data transmission. In addition, a first processor 140 and a first memory 160 may also be included. The first processor 140 invokes computer program instructions recorded on the first memory 160 to display the ultrasound image on the first touch screen 130 and/or to form a graphical user interface on the touch screen. In one embodiment, a Graphical User Interface (GUI) is displayed on the first touch display 130 and graphical controls such as those mentioned above with respect to ultrasound imaging parameter adjustments, various function buttons, and the like, involved in ultrasound image imaging procedures are presented. Control instructions for corresponding operations on the graphical controls, which are generated by operations on the touch display by the input object, can be obtained based on a Graphical User Interface (GUI), and the control instructions regarding information such as ultrasonic imaging parameters and the like can be transmitted to the ultrasonic medical detection device 100 in a wired or wireless manner and used for controlling the operation of the probe, the transmitting circuit, the receiving circuit and the like to obtain a desired ultrasonic image. For the display of the ultrasound image, for example, the ultrasound image may be displayed on two display screens, respectively, or displayed on the same display screen in a split-screen manner. The ultrasonic image may be displayed on the touch display screen, and a Graphical User Interface (GUI) for inputting a user operation instruction may be displayed.

Based on the graphical user interface displayed on the touch display screen, the first processor 140 may invoke the gesture detection module 113 stored in the memory 160 to detect a control instruction obtained by the user performing a contact operation on the graphical user interface through the input object. In various embodiments, the touch screen display device includes a touch screen display having a Graphical User Interface (GUI), one or more processors, memory, and one or more modules, programs, or sets of instructions stored in the memory for performing various functions, which collectively enable detection of and derivation of associated control instructions based on Graphical User Interface (GUI) manipulation input. In various embodiments, these functions may include parameter adjustment, information entry, etc. of the subject (e.g., patient tissue) to obtain medical test data, image review, pathology database construction, retrieval and maintenance, patient profile information construction, display and management, patient catalog information construction, display and management, etc. The means, programs or instructions for executing may be included in a computer program product configured for execution by one or more processors. In some of the embodiments of the present invention, a user interacts with a graphical user interface primarily through gesture inputs on a touch display screen. Gesture input herein may include any type of user gesture input that may be detected by a device by direct contact or proximity to a touch display screen. For example, the gesture input may be an action of a user selecting one location, multiple locations, and/or multiple consecutive locations on the touch display screen using a finger of a right or left hand (e.g., index finger, thumb, etc.), or an input object detectable by touching the display screen (e.g., a stylus, a pen dedicated to touching the display screen), and may include an operation action like contact, release of touch, tap of touch, long contact, rotational spread, and the like. Here, the long contact corresponds to one gesture input of moving a finger, thumb, stylus pen, or the like in a predetermined direction or a variable direction while maintaining a continuous contact state with the touch display screen, for example, a gesture operation action such as a touch drag, flick, wipe, slide, sweep, or the like. As can be seen, the gesture input is realized by the contact of the input object with the touch display screen, the contact with the touch display screen may include the direct contact with the touch display screen by a finger, a thumb, a stylus pen or the like, or the indirect contact with the touch display screen, and the gesture input close to the touch display screen without direct contact refers to a gesture operation action on a spatial position close to the touch display screen. The graphical user interface refers to the overall design of human-computer interaction, operation logic and interface beauty of software, and can comprise one or more soft keyboards and a plurality of graphical control objects. The soft keyboard may include a number of icons (or soft keys). This may allow the user to select one or more icons in the soft keyboard and thus select one or more corresponding symbols for input. The gesture detection module 113 may detect gesture input interacting between an input object and the touch display screen. The gesture detection module 113 includes various program modules for performing various operations related to gesture input detection, such as determining whether contact has occurred, determining whether the gesture input is continuously input, determining whether a predetermined gesture corresponds to, determining an operation position corresponding to the gesture input, determining whether the operation position corresponding to the gesture input moves to an edge position of a corresponding display area, determining whether the gesture input has been interrupted (e.g., whether contact has stopped), determining movement of the gesture input and tracking a movement trajectory of the gesture input, and so on. Determining the motion of the gesture input may include determining a rate of motion (magnitude), a speed of motion (magnitude and direction), and/or an acceleration of motion (change in magnitude and/or direction), a trajectory of motion, etc., of the operation location to which the gesture input corresponds. These operations may be applied to a single operation location (e.g., gesture input by one finger), or to multiple simultaneous operation locations (e.g., "multi-touch," i.e., gesture input by multiple fingers). In some embodiments, the gesture detection module 113 is used to detect motion of one or more input objects on the surface of the touch display screen or at spatial locations proximate to the touch display screen. The gesture detection module 113 is stored in the memory, and is invoked by one or more processors to monitor the gesture input, and obtain an operation input instruction of the user.

Of course, in the embodiment shown in fig. 1, the first processor 140 and the first memory 160 may be disposed on the main board 106, or may be disposed separately from the main board 106, or may be integrally mounted with the touch display screen 130 to form a separate display controller, that is, to implement the display of the ultrasound image, or to implement the control instruction for obtaining the user input based on the ultrasound image. In one embodiment, the signal processing module 116 and/or the image processing module 126 of fig. 1, together with the first processor 140, may be collectively configured to perform data processing of ultrasound images on one or more processors, as well as monitoring of the gesture inputs and generation of a graphical user interface as described above.

Fig. 2 provides a schematic structural diagram of another embodiment. As shown in fig. 2, the ultrasonic medical inspection apparatus 200 includes: a probe 201, a transmission circuit 203, a transmission/reception selection switch 202, a reception circuit 204, a beam synthesis module 205, a signal processing module 216, and an image processing module 226. In the present embodiment, the functions and implementations of the probe 201, the transmitting circuit 203, the transmitting/receiving selection switch 202, the receiving circuit 204, the beam forming module 205, the signal processing module 216 and the image processing module 226 are the same as those of the probe 101, the transmitting circuit 103, the transmitting/receiving selection switch 102, the receiving circuit 104, the beam forming module 105, the signal processing module 116 and the image processing module 126 in the embodiment shown in fig. 1, and reference to the foregoing descriptions will not be repeated here. In some embodiments of the present invention, the signal processing module 216 and the image processing module 226 in fig. 2 may be integrated on one main board 206, or one or more (including the same number) modules may be integrated on one processor/controller chip. The difference from the embodiment shown in fig. 1 is that the ultrasonic medical inspection apparatus 200 further includes: the first communication module 215 is electrically connected to the image processing module 226, and is configured to transmit the ultrasound image data obtained by the image processing module 226 to the intelligent controller 270, and/or receive a control signal input by the intelligent controller 270 to set an ultrasound imaging parameter used in the ultrasound imaging process. The operation of setting the ultrasonic imaging parameters includes updating the ultrasonic imaging parameters, adjusting the ultrasonic imaging parameters, or initializing the setting of the ultrasonic imaging parameters. The intelligent controller 270 in the present embodiment includes: a second touch display 230, a second processor 240, a second memory 260, and a second communication module 214. The second memory 260 stores computer programs, such as the gesture detection module 213, running on the second processor 240, in which the gesture detection module 213 has the same function as the gesture detection module 113 in the embodiment shown in fig. 1, and the description thereof will not be repeated. The second touch screen 230 is implemented with the same function as the first touch screen 130, but the specific product parameters may not be the same, and the terms "first" and "second" are only used to distinguish entities in different application scenarios in the embodiments, and the following description about the method steps or the description of a single application scenario may be equally understood as a touch screen in the conventional sense, so that the description elsewhere herein may be simply referred to as a touch screen. The second communication module 214 receives ultrasound image data transmitted from the first communication module 215 and/or sends control signals, such as control signals containing ultrasound imaging parameter setting information, to the first communication module 215. The smart controller 270 includes the display controller mentioned in fig. 1, but may also include computer devices with touch screens such as various smart terminal devices, e.g., IPAD, cell phone, etc. The communication mode of the first communication module 215 and the second communication module 214 may adopt a wifi protocol, a bluetooth transmission protocol, a mobile communication network protocol, and the like. The ultrasonic medical testing device 200 and the intelligent controller 270 form an ultrasonic imaging system.

Based on the structural schematic diagram of the ultrasonic medical detection apparatus (100, 200) provided in fig. 1 or fig. 2, the following will describe in detail the setting manner of the ultrasonic imaging parameters in conjunction with the hardware environment provided in fig. 1 or fig. 2.

The equipment disclosed in the embodiment is an ultrasonic imaging system capable of adjusting imaging parameters of ultrasonic medical detection equipment through touch control, and the imaging parameters and the image data are obtained through interaction between a user and the ultrasonic imaging equipment more intuitively through a graphical user interface on a touch display screen, so that the convenience of the user in operating the ultrasonic equipment is improved, and the user experience is improved. When parameters are adjusted in a sliding manner on a touch screen (namely, a touch display screen), adjustment interfaces of the parameters are simultaneously displayed on the touch screen and the displayed adjustment interfaces change along with the sliding of a finger or a stylus. When the adjusted parameters are such discontinuous parameters, the parameters can only take discontinuous values, so that the displayed adjustment interface can generate a 'jumping' phenomenon during adjustment, and the adjustment and use experience of the user on the parameters are influenced. Moreover, when the user adjusts, it is difficult to precisely position the adjustment mark to a desired level or position of a gear on the parameter adjustment interface, which is inconvenient for the user to adjust the parameter and inconvenient for use. The ultrasonic parameter selection mode provided in the embodiment can well avoid the problem, when a user adjusts the operation parameters on the touch screen, the adjustment effect of adjusting the movement of the identification along with the touch of the user can be better experienced, the problem of inaccurate adjustment and positioning caused by random jumping of the identification can be avoided, and the user can conveniently and accurately position the identification to a desired level or gear position. Therefore, the present embodiment provides the following control manner of the ultrasonic imaging parameters shown in fig. 3. Fig. 3 provides a flow chart of the ultrasound imaging control method in the embodiment shown in fig. 1 or fig. 2. FIG. 4 provides one display embodiment of a graphical user interface of the embodiment of FIG. 3. Fig. 5 provides another display embodiment of the graphical interface of the example of fig. 3, and fig. 5 differs from fig. 4 in the arrangement direction of the information indicators. Fig. 6 shows a variant of the second region of the embodiment of fig. 3.

In step S210 of fig. 3, the transmitting circuit and the receiving circuit (103 and 104, 203 and 204) excite the probe (201, 101), transmit an ultrasonic beam to the inspection object according to the set ultrasonic imaging parameters, and in step S212, the exciting probe (201, 101) receives an echo of the ultrasonic beam, obtaining an ultrasonic echo signal.

In step S214 of fig. 3, an ultrasound image is obtained by the image processing module according to the ultrasound echo signal, for example, the ultrasound image is obtained by the image processing module (126) in the embodiment of fig. 1, and the ultrasound image is obtained by the image processing module (226) in the embodiment of fig. 2. Also provided within the ultrasound medical detection apparatus of fig. 1 is a first memory for storing a computer program running on a processor, such as the gesture detection module 113 described above. While a second memory is provided in the intelligent controller 270 in fig. 2 for storing a computer program running on a processor, such as the gesture detection module 213 described above. The ultrasound image may be an ultrasound image of the different modes described above, such as a B image, a C image, a D image, etc., or other types of two-dimensional ultrasound images or three-dimensional ultrasound images. Similarly, the ultrasound images referred to herein may be still frame images or dynamic video images.

In step S216 of fig. 3, the first processor 140 or the second processor 240 of fig. 2 establishes a plurality of discrete alternatives according to the ultrasound imaging parameters. For an explanation of the ultrasound imaging parameters, see the relevant description above. In one embodiment, the ultrasound imaging parameter in this embodiment is one of TGC (Time Gain compensation), acoustic frequency, Pulse Repetition Frequency (PRF), ultrasound type, and dynamic range. For example, the discrete alternatives obtained for TGC may be 1.5, 2.5, 3.5, etc., respectively.

In step S218 of fig. 3, the first processor or the second processor 240 of fig. 2 displays a plurality of information indicators 305 (as shown in fig. 4) on the first touch display 130 or the second touch display 230 at intervals of a preset sequence, and one information indicator 305 corresponds to one discrete option association. A plurality of information indicators 305 may be disposed within region 301 (shown in fig. 4). Here, the interval arrangement may be an equal interval arrangement.

The information indicator 305 may be presented in the form of a prompt of interface text, a prompt of drawing a scale indicator, or the like. The preset arrangement order in this embodiment may be an arrangement along a straight line, an arrangement along a curved line, or an arrangement along a circle, etc. In one embodiment, as shown in FIG. 4, a plurality of information indicators 305 corresponding to a plurality of discrete alternatives to TGC are displayed in a linear arrangement on a graphical user interface of a touch screen display. A plurality of information indicators 305 are presented on the graphical user interface in the form of tick prompts and text prompts for alerting the user to discrete alternate information, such as numerical values. A plurality of information indicators 305 are displayed in a region 301 on the graphical user interface, and the region 301 may be any one pixel region on the graphical user interface, for example, may be located near the ultrasound image display region, or may be a pixel region within the ultrasound image display region. Of course, the area 301 may also be displayed superimposed on the ultrasound image, for example, the graphical user interface may include at least two interface layers, the ultrasound image is displayed on a first interface layer of the touch screen, a second interface layer disposed transparently is superimposed on top of the first interface layer, and the plurality of information indicators 305 are disposed on the second interface layer. Such an arrangement allows the information indicator 305 to be suspended above the ultrasound image without obstructing the display of the ultrasound image and enables the user to observe changes in the ultrasound image due to adjustments based on the ultrasound imaging parameters. Further, in one embodiment, a floating window is displayed on the touch screen display, and the floating window can be moved to any pixel area position on the graphical user interface. The above-mentioned region 301 is provided within the floating window, and a plurality of information indicators 305 are provided within the region 301, facilitating the user to visually learn a plurality of discrete alternatives to the relevant ultrasound imaging parameters. And displaying the floating window on the touch display screen based on the received adjusting trigger signal from the user.

Another embodiment of a graphical user interface is presented in fig. 5. A graphical user interface 400 is displayed on a touch screen display with ultrasound images displayed in an area 402 on the interface. A plurality of information indicators 415 are displayed in a preset order in field 416, with one information indicator 415 corresponding to one discrete alternative association. Region 416 may be any pixel region on the graphical user interface, and may be located, for example, near the ultrasound image display area, or as a pixel region within the ultrasound image display area. The information indicator 415 may be presented in the form of a prompt of interface text, a prompt of drawing a scale indicator, or the like.

Further, in one embodiment, as shown in fig. 4 or 5, a plurality of display areas (309, 418) are arranged along the arrangement direction of the information indicators, and adjacent display areas are arranged at intervals, for example, the plurality of display areas are arranged at equal intervals. And each display area is used for displaying an information indicator. The purpose of the method is to enable the information indicator to be accurately indicated when the indication mark is positioned in the display area, and accurately prompt the user of the scale information of the discrete alternative selected by the user. The display area refers to a position corresponding to the information indicator in association on the graphical user interface, and when the indication mark is located in the display area, the indication mark represents that the display information indicator corresponding to the display area in association is selected, and each display area can be 1 or more pixel positions.

In step S220 of fig. 3, the first processor 140 or the second processor 240 of fig. 2 displays an indicator on a touch display screen (e.g., the first touch display screen 130 or the second touch display screen 230). As shown in fig. 4 or fig. 5, the first processor 140 or the second processor 240 displays an indicator (412, 302) in a predetermined area (301, 416). In fig. 4 and 5, the indicators are represented by black squares and arrows, but other square blocks, triangular marks, and other arbitrary-shaped indicators may be used, such as the hollow boxes shown in fig. 7 to represent the indicators 712.

As shown in fig. 4 or fig. 5, the indicator (412, 302) can be moved to any operation position within a predetermined area along the arrangement direction of the information indicators, where the predetermined area can be an area 301 or an area 416, i.e., an area where a plurality of information indicators are displayed. The operation position on the interface mentioned in the present document refers to a position on the display interface corresponding to the operation input of the user on the interface object (for example, the indication mark) by using the human-computer interaction device. The "position" mentioned herein includes orientation information, coordinate information, and/or angle information, etc., and for example, regarding the display position of the indicator mark on the graphical user interface, it can be characterized by coordinate information of a pixel point where the indicator mark is located, and also can be characterized by a position mark occupied along the arrangement direction of the information indicator. The indicator may also be disposed on top of the second interface layer. Similarly, the area 416 may be provided in the floating window together with the area 301, and the indicator may be displayed in the floating window.

The method may further include, after the step S220: the first processor 140 or the second processor 240 in fig. 2 associates the recorded display area (309 or 418) with the discrete alternative, and for example, the recorded display area (309 or 418) and the discrete alternative may also be stored in the first memory. A discrete alternate association corresponds to a display area (309 or 418) on the touch screen display (300 or 400). The mode of recording the corresponding relation between the display area (309 or 418) and the discrete options can be a pixel area range of the recording display area (309 or 418) on the touch display screen, and the corresponding relation of the values of the discrete options is convenient for quick searching according to the input of a user subsequently.

In step S224 of fig. 3, the first processor 140 or the second processor 240 of fig. 2 calls the gesture detection module (113, 213) to monitor the touch of the input object on the touch display screen (e.g., the first touch display screen 130 or the second touch display screen 230).

For example, contact of an input object with a touch display screen within a predetermined area is monitored. Here, the predetermined area may include a steerable movement area indicating the identification, or a plurality of information indicators steerable movement areas, for example, the predetermined area may be the area 301 or the area 416; or may be an interface region including region 301 or region 416, or may be a region other than region 301 or region 416.

Also for example, as shown in fig. 6, an ultrasound image 606 is displayed on the graphical user interface 600, a plurality of information indicators 601 are displayed at intervals in a preset sequence in a region 612, an indicator 602 is displayed in the region 612, a plurality of display areas 613 are further provided in the region 612, and each display area 631 displays one information indicator 601 correspondingly. In step S226, the first processor 140 or the second processor 240 in fig. 2 calls the gesture detection module (113, 213) to monitor the third area 608 of the input object 604 contacting the touch screen (130 or 230). The third region 608 is disposed in a region other than the region 612. While the touch operation in the third area 608 affects the relative position relationship between the plurality of information indicators 601 and the indicator 602 in the area 612. The one-touch operation includes one touch of an input object on the touch display screen and release of the one touch.

In one embodiment, after the step S224, the method further includes:

the first processor 140 or the second processor 240 in fig. 2 can enlarge more details about the plurality of information indicators according to the initial contact of the input object with the touch screen display before moving the indication mark or the display of the plurality of information indicators according to the above contact, facilitating a user to more accurately locate a specific discrete value to which the ultrasound imaging parameters are desired to be adjusted.

For example, as shown in FIG. 7, ultrasound image 702 is displayed on graphical user interface 700, a plurality of information indicators 715 are arranged along a circular interval on graphical user interface 700, and each display 718 of the plurality of spaced apart displays 718 displays one information indicator. The first processor 140 or the second processor 240 in fig. 2 identifies that the contact of the input object 703 on the touch display screen corresponds to a first operation position on the touch display screen, where 7191 in fig. 7 is an initial contact position of the first operation position, and then searches for at least a portion of the plurality of information indicators 715 associated with the first operation position (e.g., the initial contact position); second, at least a portion of the plurality of information indicators 715 found is magnified so that the user can clearly see more details of the discrete alternatives indicated by the information indicators. Further, in one embodiment, as shown in fig. 7, the first processor 140 or the second processor 240 in fig. 2 establishes a plurality of sub-levels of discrete alternatives between two discrete alternatives corresponding to two information indicators based on at least a part of the searched plurality of information indicators 715. For example, if the initial contact location 7191 is selected between the information indicators "35" and "40," then the discrete alternatives at multiple sub-levels between the two discrete alternatives "35" and "40" to which the two information indicators correspond will be expanded. The plurality of information indicators 715 within the frame area on the interface 700 are changed to the display result within the dashed-line frame 721 pointed to by the indication line 720 after the input object 703 contacts the touch display screen. The discrete alternatives "37", "39" will be expanded into a plurality of sub-stages between "35" and "40", and the rest of the plurality of information indicators 715 will also expand the discrete alternatives of the plurality of sub-stages in sequence. The information indicators of a plurality of sub-levels are arranged and displayed on the touch display screen at intervals according to a preset sequence, and the information indicator of one sub-level is associated and corresponds to the discrete alternative of one sub-level. Therefore, the discrete alternatives pointed by the original information indicators are displayed in a scale-up mode due to the contact of the input object and the touch display screen. Of course, in order to distinguish the contact cause causing the enlargement effect from the contact causes of the following movement indication mark or the plurality of information indicators, it can be determined from the time of contact, and if the time of contact between the input object and the touch display screen exceeds a certain threshold value at the same operation position, it is considered that it is desirable to enlarge at least a part of the plurality of information indicators at the same ratio, the enlargement effect shown in fig. 7 is caused, whereas if the time of contact between the input object and the touch display screen does not exceed the certain threshold value at the same operation position, it is not considered that it is desirable to enlarge at least a part of the plurality of information indicators at the same ratio, and the display result of the broken line box 721 shown in fig. 7 will not occur.

In step S226 of fig. 3, the first processor 140 or the second processor 240 of fig. 2 moves the indication identifier or the display of the information indicators according to the contact of the input object monitored on the touch display screen (e.g., the first touch display screen 130 or the second touch display screen 230), so that the position relationship between the indication identifier and the information indicators is changed.

For example, in one embodiment, the first processor 140 or the second processor 240 in fig. 2 tracks and monitors the movement of the contact, determines that the movement of the contact is associated with a second operation position on the touch screen display, and moves the display indicator or the plurality of information indicators according to the change of the second operation position, so that the position relationship between the indicator and the plurality of information indicators changes.

The first processor 140 or the second processor 240 in fig. 2 determines the operation position on the touch display screen associated with the contact with the touch display screen (130, or 230) as described above, i.e., the second operation position. The second operating position may be located within

region

301, 416, or 612, or within region 608 (i.e., one of interface regions 608 disposed on the graphical user interface other than region 612 in fig. 6). In one embodiment, in the example shown in FIG. 6, the input object 604 is not slid directly in the area 612, but rather is slid in a control area (i.e., the third area 608) on the touch screen (130, or 230). When the input object 604 slides in the control area 608, the corresponding indicator 602 correspondingly slides in the area 612, i.e., the adjustment of the ultrasound imaging parameters is achieved by the movement of the input object 604 in the control area 608 controlling the sliding of the indicator 602 in the area 612. Therefore, according to the contact of the input object 604 in the third region 608, the second operation position 615 corresponding to the region 612 can be obtained.

In other embodiments, in the embodiment shown in fig. 4, when the input object 308 slides in the area 301, the corresponding operation position in the area 301 can be obtained according to the sliding contact, so as to obtain the second operation position (3111, 3112).

Further, as shown in fig. 4 and 5, in step S226, the first processor or the second processor 240 in fig. 2 invokes the gesture detection module (113, 213) to track and monitor the movement of the contact of the input object with the touch display screen (130, or 230), which generates the continuous contact result of the input object with the touch display screen, such as the long contact mentioned above. For example, in one embodiment, the continuous contact of the input object on the touch display screen (130, or 230) is monitored in step S226, and the first processor 140 or the second processor 240 in fig. 2 can recognize a series of continuously changing positions on the touch display screen (130, or 230) through the gesture detection module. Then, in step S228, as in the embodiment shown in fig. 4, 5 or 6, the first processor or the second processor 240 in fig. 2 determines a plurality of operation positions of the contact on the touch display screen (130 or 230), and a plurality of continuously changing second operation positions can be obtained. Of course, the change may be arranged along the arrangement direction of the information indicator at a plurality of continuously changing second operation positions.

Next, the first processor 140 or the second processor 240 in fig. 2 moves the display indicator or the plurality of information indicators according to the change of the second operation position, so that the positional relationship between the indicator and the plurality of information indicators changes. For example, in the process of moving the display indicator or the plurality of information indicators, as shown in fig. 4, when the contact of the input object 308 with the touch display screen is moved from the first operation position 3111 to the first operation position 3112, the display of the indicator 302 is moved from the first operation position 3111 to the first operation position 3112; as shown in fig. 5, when the contact of the input object 403 with the touch display screen is moved from the first operation position 4121 to the first operation position 4122, the display of the indicator 412 is moved from the first operation position 4121 to the first operation position 4122, so that the deflection of the indicator 412 is indicated between the information indicators "60" and "80"; as shown in fig. 6, when the contact of the input object 604 with the touch display screen is moved from the first operation position 615 to the first operation position 616, the display of the indicator 602 is moved from the first operation position 615 to the first operation position 616, so that the indicator 602 is deviated from one of the information indicators 601. For another example, as shown in fig. 8, when the contact of the input object 703 with the touch display screen is moved from the first operation position 7191 to the first operation position 7192, the display of the plurality of information indicators 715 is moved from the first operation position 7191 to the first operation position 7192, that is, as a result of the display indicated by the dashed-line box 732 indicated by the indication line 730 in fig. 8, the plurality of information indicators 715 are arranged in a circle, and as compared with the result of the display within the square box 731 in fig. 8, the result of the display within the dashed-line box 732 in fig. 8 is deflected clockwise by an angle such that the indicator 712 is deflected from being directed to the information indicator "20", to being directed between the information indicators "75" and "80".

In the process of moving the indication mark or the plurality of information indicators according to the contact, the display is updated, that is, the updating is to delete the display of the indication mark at the original position and change the position of the indication mark to the position related to the second operation position, so that the indication mark or the plurality of information indicators changes along with the change of the second operation position. The meaning of "change" herein may also be understood as changing, transforming, or replacing the display position of the interface object on the interface.

For example, in one embodiment, the steps S224 to S226 include: the first processor 140 or the second processor 240 in fig. 2 invokes a gesture detection module to monitor a continuous contact of an input object on the touch display screen (130 or 230), determine a plurality of operation positions corresponding to the continuous contact on the touch display screen, and obtain a plurality of continuously-changing first operation positions; and sequentially moving the display of the indicator to a plurality of continuously changing first operation positions so that the indicator changes following the change of the second operation position. As shown in fig. 4, when the input object 308 is continuously moved in the direction 306 or the direction 307 within a predetermined area of the touch display screen to make a continuous contact with the touch display screen, and the first processor monitors the continuous contact by calling the gesture detection module, a set of a plurality of continuously changing second operation positions (3111, 3112) may be obtained, the set of the plurality of continuously changing second operation positions (3111, 3112) sequentially changing along the arrangement direction of the information indicator and possibly crossing at least one display area 309 along the arrangement direction of the information indicator, and the display of the indicator 302 is sequentially moved to the plurality of continuously changing second operation positions according to the recognition of the plurality of continuously changing second operation positions (3111, 3112) so that the indicator changes following the change of the second operation positions.

Further, in one embodiment, sequentially updating the display of the indicator in the second operating position includes: the first processor or the second processor 240 in fig. 2 calls the gesture detection module to recognize the position change of the second operation position in the arrangement direction of the information indicators, and sequentially changes the position of the indication mark in the arrangement direction of the information indicators to the position of the second operation position in the arrangement direction of the information indicators according to the position change of the second operation position in the arrangement direction of the information indicators, thereby realizing moving the display indication mark according to the change of the second operation position.

For example, assuming that a certain pixel point position on the coordinate system is represented by (X, Y) in the rectangular coordinate system, the plurality of information indicators 305 in fig. 4 are arranged in the vertical direction (i.e., Y direction), and when the second operation position is changed from the position 3111 to the position 3112 in the direction 307 in fig. 3, the position 3111 and the position 3112 may be respectively represented by (X1, Y1), (X2, Y2), in which a position change of the second operation position in the vertical direction (i.e., Y direction) is recognized (Y1 → Y2), and then the position of the indicator (302) in the vertical direction (i.e., Y direction) is updated to a changed position Y2 of the second operation position in the vertical direction, i.e., the position of the indicator in the rectangular coordinate system is indicated at (X1, Y2), according to the recognized position change (Y1 → Y2). Of course, the change of the second operation position may be only a change in the Y direction, i.e., the position 3111 and the position 3112 may be represented as (x1, Y1), (x1, Y2), respectively. In this embodiment, x \ y may represent not only one coordinate position value, but also a certain coordinate range, or a central point coordinate position in a certain range. Likewise, in fig. 5, a positional change of the second operation position in the horizontal direction (i.e., the X direction) is recognized, and an operation of updating the display of the indicator 412 at the second operation position 4121 is performed. With this display mode, the movement of the indicator can be restricted so as to move only within the second area as the movement of the input object changes, for example, to any one operation position within a predetermined area along the arrangement direction of the information indicators.

Furthermore, in some embodiments, before the process of step S226 to step S234, the following steps may be further included:

the first processor 140 or the second processor 240 in fig. 2 invokes the gesture detection module to detect whether the contact between the input object and the touch display screen (130 or 230) is located in the operation position of the indication mark, and when the contact between the input object and the touch display screen (130 or 230) is located in the display area of the indication mark, the processes of the steps S226 to S234 are performed. On the contrary, when the contact of the input object with the touch display screen (130, or 230) is not in the display area where the indication mark is located, the display position of the indication mark is not updated, and the processes of the above step S226 to step S234 are not executed. The process from step S226 to step S234 can be described with reference to the above description. The embodiment can ensure the accuracy of control signal input and ensure the selection reliability of discrete alternatives by tracking and monitoring the input operation of the input object contacting the touch display screen (130 or 230) to the indication mark. For example, as shown in fig. 5, first, the first processor or the second processor 240 in fig. 2 invokes the gesture detection module to detect whether the contact between the input object 403 and the touch display screen (130, or 230) is located in the operation position where the indicator 412 is located in the area 416, that is, determine whether the operation position 411, where the contact between the input object 403 and the touch display screen (130, or 230) is located on the touch display screen (130, or 230), coincides with the operation position where the indicator 412 is located, if so, execute the processes of the above steps S226 to S230, and start to track and monitor the movement of the contact between the input object 403 and the touch display screen (130, or 230) along the direction 404 or the direction 405. Otherwise, the display position of the indication mark is not updated according to the detected contact of the input object 403 with the touch display screen (130, or 230), i.e., the processes of step S226 to step S234 are not performed.

In the above-mentioned process from step S226 to step S234, the indication mark may change the display position along with the continuous contact of the input object with the touch display screen, and in order to improve the visualization effect of the indication mark along with the continuous contact, in the process of updating the display of the indication mark to the second operation position, the moving speed of the indication mark between the two operation positions on the graphical user interface may be calculated according to the display moving speed of the visualization, and the display movement of the indication mark between the two first operation positions may be adjusted based on the moving speed, so as to present the continuous display moving effect.

In addition, in one embodiment, the manipulated object may not be the indicator, but may be a plurality of information indicators, so as shown in fig. 8, the first processor 140 or the second processor 240 in fig. 2 invokes the gesture detection module to recognize a change direction of the second operation position generated by the input object 703 contacting the touch display screen; the plurality of information indicators are moved along the direction of change in accordance with the detected direction of change. For example, in fig. 8, a shift of the second operation position from 7191 to 7192 is detected, and the direction of the shift is clockwise, so that moving the plurality of information indicators 715 clockwise causes the relative positional relationship between the indicator 712 and the plurality of information indicators to change.

In step S228 of fig. 3, the first processor 140 of fig. 1 or the second processor 240 of fig. 2 invokes the gesture detection module to detect a release of the input object from contact with the touch display (130, or 230).

In one embodiment, the first processor 140 of FIG. 1 or the second processor of FIG. 2 detects the release of the contact by at least one of the following means.

1. The disengagement of the contact between the input object and the touch display screen (130, or 230) is monitored on the touch display screen, that is, the input object no longer performs an input operation on the touch display screen.

2. Whether the contact between the input object 403 and the touch display screen (130 or 230) is located outside a preset area is monitored, and when the contact is located outside the preset area, the contact is considered to be released, and the input object does not perform input operation on the touch display screen any more.

When detecting that the input object is in contact with the touch display screen (130 or 230) to generate release, the first processor 140 in fig. 1 or the second processor in fig. 2 detects that the release of the contact is in a third operation position on the touch display screen. For example, the touch display screen is monitored for a release of contact between the input object and the touch display screen (130, or 230), and the operation position at which the contact was located before the release is taken as the third operation position. As shown in fig. 5, contact between the input object 403 and the touch display screen (130, or 230) within the region 416, the processor detects movement of the contact from the first operational position 4121 to the first operational position 4122, and thus also continuously updates the display of the indicator 412 for continued movement to the first operational position 4122. At this time, the disengagement of the contact between the input object 403 and the touch display screen (130, or 230) is detected at the first operation position 4122, and the operation position 4122 at which the contact was located before the disengagement is identified as the third operation position. Also as in fig. 8, continuous contact between the input object 703 and the touch screen display (130, or 230) in either

direction

704 or 705 is monitored within a predetermined area (in fig. 8, the area where the plurality of information indicators are displayed), the processor detects that the contact association of the two is moving from the first operational position 7191 to the second operational position 7192 within the predetermined area, and thus also continuously updates the display of the indicator 712 for continuous movement to the second operational position 7192. At this time, when the processor detects that the contact between the input object 403 and the touch display screen (130 or 230) is released while the indicator 712 is displayed at the second operation position 7192, the processor recognizes the operation position 7192 at which the contact was located before the release as the third operation position, and at this time, the relative positional relationship between the plurality of information indicators and the indicator jumps from the display result indicated by the broken-line frame 732 to the display result indicated by the display frame 733 as indicated by the indicator line 740. In addition, although the operating positions in different cases are distinguished herein by "first" or "second" and "third" for distinguishing at the time of description, the operating positions therefore include a first operating position, a second operating position and a third operating position; the second operation position may include a first operation position, which is an operation position generated by an initial contact between the input object 403 and the touch display screen (130, or 230), and belongs to a starting point of a change of the second operation position.

For example, it is detected whether a contact between an input object and the touch display screen (130, or 230) is outside a predetermined area, and when the contact is outside the predetermined area, the last operation position in which the contact corresponds to an area within which a plurality of information indicators are displayed is identified as the third operation position. The predetermined region may be the

region

416 or 301 described above, or the third region (608 in fig. 6) described above. For example, in fig. 6, a gray arrow mark indicates a history display position of the indicator 602, and a black arrow mark indicates a current display position of the indicator 602. Continuous contact between the input object 604 and the touch screen display (130, or 230) in either

direction

603 or 605 is monitored within the third region 608, and the processor detects that the contact association of the two is moving from the first operative position 615 to the first operative position 616 within the region 612, thereby also continuously updating the display of the indicator 602 for continuous movement to the first operative position 616. At this time, when the display of the indicator 602 is at the first operation position 616, the processor detects that the contact between the input object 403 and the touch display screen (130, or 230) is located outside the third region 608, and recognizes the last operation position 616 corresponding to the contact within the region 612 as the third operation position.

In step S230 of fig. 3, the first processor or the second processor 240 of fig. 2 adjusts the relative position between the indicator and the plurality of information indicators according to the relative position relationship between the indicator and the plurality of information indicators when the contact is released, so that the indicator directly faces one of the plurality of information indicators.

For example, in one embodiment, step 230 is implemented as follows: the first processor or the second processor 240 in fig. 2 sets a plurality of display areas arranged at intervals on the touch display screen, each display area is used for displaying an information indicator, and a third operation position generated on the touch display screen by releasing the input object from contacting the touch display screen is identified; searching a display area associated with the third operation position; and displaying the indication mark in the searched display area, thereby realizing that the indication mark is just opposite to one of the information indicators. As shown in fig. 5, a plurality of display areas 418 arranged at intervals are arranged on the touch display screen, each display area 418 is used for displaying an information indicator 415, and a third operation position 4122 generated on the touch display screen by the release of the input object 403 from the touch display screen is identified; searching for a display area 4181 associated with the third operation position 4122; and, the indication mark 412 is displayed in the found display area 4181. It can thus be seen that when the contact of the input object 403 with the touch display screen is released, from the time of the release of the above-mentioned contact, where the indicator 412 indicates a position between the information indicator "60" and the information indicator "80", a jump is made to a position where the indicator 412 is directly facing the indicator information indicator "80". As also shown in fig. 6, a plurality of display areas 613 arranged at intervals are provided on the touch display screen, each display area 613 is used for displaying an information indicator 601, and a third operation position 616 generated on the touch display screen by releasing the input object 604 from contacting the touch display screen is identified; searching for a display area 6131 associated with the third operation position 616; and, the indication mark 602 is displayed in the found display area 6131. It can thus be seen that when the contact of the input object 604 with the touch display screen is released, from the release of the contact, where the indicator 602 indicates a position offset from one of the information indicators, a transition is made to a position where the indicator 602 is indicating one of the information indicators (the indicator 602 is indicating a scale "12").

In step 230, the first processor or the second processor in fig. 2 searches the display area associated with the third operation position in one of the following manners.

1. For example, as shown in fig. 5, the display area 4181 closest to the third operation position 4122 is searched for, and the display area closest to the third operation position is set as the display area associated with the third operation position.

2. For example, as shown in FIG. 6, contact of the search input object 604 with the third region 608 causes a display region 6131 that the display of the indicator last crossed. That is, the display area that was last crossed by the continuous contact of the input object 604 with the touch display screen within the area 612 is searched for according to the third operation position.

For another example, in one embodiment, the step 230 is implemented as follows: the first processor or the second processor 240 in fig. 2 sets a plurality of display areas arranged at intervals on the touch display screen, wherein each display area is used for displaying an information indicator; recognizing a third operation position generated on the touch display screen by releasing the input object from the touch display screen; searching for one of a plurality of information indicators located in the vicinity of the indicator; and displaying one of the searched information indicators at a position opposite to the indication mark. For example, as shown by the dashed box 733 in FIG. 8, a plurality of spaced apart display areas 718 are provided on the touch screen display, each display area 718 being configured to display an information indicator 715; recognizing that the release of the input object 703 from contact with the touch display screen results in a third operational position 7192 on the touch display screen; looking up one of a plurality of information indicators, such as information indicator "80", or information indicator "75", located near indicator 712; and, the information indicator "80" or the information indicator "75" is displayed at a position directly opposite to the indication mark 712, which is indicated by a dotted line in fig. 8. It can thus be seen that when the contact of the input object 703 with the touch display screen is released, from the time of the release of the above-mentioned contact, the indicator 712 indicates a position intermediate the information indicators "75" and "80", a jump is made to the point where the indicator 712 is directly facing the information indicator "80".

In step S232 of fig. 3, the first processor or the second processor in fig. 2 determines the discrete alternative corresponding to the information indicator directly opposite to the indication mark.

In the embodiment of fig. 5, the information indicator "80" indicating that the mark is positive is determined as the discrete alternative "80"; in the embodiment of fig. 6, the indication marks the positive information indicator "12", and the discrete alternative determined is the scale "12". Each processor can determine the discrete alternative corresponding to the information indicator opposite to the indication mark by searching the relation between the display area occupied by the information indicator and the discrete alternative.

Then, in step S234 of fig. 3, the first processor or the second processor in fig. 2 adjusts a parameter value corresponding to the ultrasound imaging parameter according to the determined discrete alternative item corresponding to the information indicator directly opposite to the indication identifier, and obtains the ultrasound image using the adjusted parameter value. The ultrasound imaging parameters employed in the ultrasound scan are reset by the processor in accordance with the determined discrete alternatives.

In addition, for example, in the embodiment shown in fig. 2, the second processor obtains a parameter value corresponding to the ultrasound imaging parameter according to the determined discrete alternative corresponding to the information indicator directly opposite to the indication identifier, and then the intelligent controller 270 generates a control signal containing the parameter value and outputs the control signal to the first communication module 215 through the second communication module 214, so as to control the probe to perform the ultrasound scanning on the target tissue and the formation of the ultrasound image through the first processor, thereby updating the display result of the ultrasound image. The ultrasonic imaging parameters required by the ultrasonic image can be obtained according to the control signal.

Fig. 3 provides only a flow execution sequence among steps, and various modifications can be obtained by adjusting the sequence of the steps in fig. 3 based on the foregoing, and the steps are not limited to be executed only in the sequence of fig. 3, and steps may be interchanged with each other and the execution sequence may be changed if the basic logic is satisfied, and after one or more steps are repeatedly executed, the last step or steps may be executed, and these modifications all belong to the modifications performed according to the embodiments provided herein.

Through the above description of the embodiments, those skilled in the art will clearly understand that the method of the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but in many cases, the former is a better implementation manner. Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is carried in a non-volatile computer-readable storage medium (such as ROM, magnetic disk, optical disk, hard disk, server cloud space), and includes several instructions for enabling a terminal device (which may be a mobile phone, a computer, a server, or a network device) to execute the system structure and method according to the embodiments of the present invention. For example, a computer-readable storage medium, on which a computer program is stored, which, when being executed by a processor, can be used at least to implement the aforementioned embodiments based on the flow shown in step S216 to step S234 in fig. 3.

When the discontinuous parameters are adjusted, a finger or a touch pen presses the parameter adjusting mark to slide on the touch display screen, and the parameter adjusting mark slides along with the finger or the touch pen in the sliding process. After releasing the finger or the stylus pen, the parameter level or the gear position closest to the position of the current parameter adjustment identification is automatically found, and the parameter is automatically adjusted to the level or the gear position. Therefore, the visual feedback on the display interface in the parameter adjusting process is improved, the parameter adjustment is facilitated, and the user experience is improved.

The above examples only show some embodiments, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
