Therefore, they should not be understood as limitations on the present invention.

[0068] In addition, in the following description, the terms "first", "second", etc. are used only to distinguish the description and cannot be understood as indicating or implying relative importance.

[0069] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0070] The present invention is preferably implemented in the form of software code, by editing the steps of the present invention into software code and installing it in a computer with computing capabilities, for example, in the form of software code, in a smart phone or tablet computer.

[0071] Those skilled in the art will appreciate that the exemplary algorithm steps described in conjunction with the embodiments disclosed herein can be implemented in electronic hardware, or in a combination of computer software and electronic hardware. Whether these functions are performed in hardware or software depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of the present invention.

[0072] The implementation of the present invention is accomplished by installing a corresponding computer program in a computer with relevant hardware. The computer program can be stored in a computer-readable storage medium. When the computer program is executed by a processor, the various steps required can be implemented. The computer program includes computer program code, which can be in source code form, object code form, executable file or some intermediate form. The computer-readable medium can include: any entity or device capable of carrying the computer program code, recording medium, USB flash drive, mobile hard disk, magnetic disk, optical disk, computer memory, read-only memory (ROM), random access memory (RAM), electric carrier signal, telecommunication signal and software distribution medium.

[0073] The computer of the present invention has the following main hardware components: display screen 1, HYPERLINK "https: / / baike.so.com / doc / 735320-778444.html" \t "https: / / baike.so.com / doc / _blank" central processing unit, memory, chipset, I / O bus, HYPERLINK "https: / / baike.so.com / doc / 6707711-6921725.html" \t "https: / / baike.so.com / doc / _blank" I / O devices, power supply and related software.

[0074] The display screen 1 includes a display screen of a personal PC desktop computer or a pen-reading computer. This type of display screen is connected to a computer motherboard, and an input device, a mouse, is connected to the motherboard. The mouse inputs instructions to a processor on the motherboard.

[0075] The display screen 1 includes a touch screen. The touch screen uses the current induction phenomenon of the user's fingertips to form a capacitor between the fingertips and the screen. When the finger touches the screen, a small current is absorbed. This current causes current to flow on the electrodes of the touch screen. The controller can calculate the coordinates of the touch point by calculating the proportion of the current. At the same time, the area where the fingertips contact the touch screen can be calculated. The "surface" referred to in the "50% contact surface of the input fingertips" described in the following example is the area where the fingertips contact the touch screen, and the "50% contact surface" is 50% of all the areas where the fingertips are currently in contact with the touch screen.

[0076] Example 1:

[0077] The blood flow image signal of the present invention is a blood flow image obtained by an ultrasonic device in a human blood vessel. It is necessary to first collect and process ultrasonic image information. To collect the ultrasonic image information, reference can be made to the ultrasonic device of the following Chinese patent CN209751086U, which can realize the collection of ultrasonic image information and the processing of ultrasonic image information.

[0078] refer to Figure 1 This embodiment includes an ultrasonic transducer for emitting a scanning beam, a digital control processing chip for controlling the ultrasonic transducer to emit a scanning beam and collect echo signals, a portable control terminal for issuing control instructions to the digital control processing chip and viewing scanned images, as well as a transmit-receive multiplexing circuit, a transmit-receive switching circuit, a transmitting circuit, a receiving circuit, a USB interface circuit, a low power module and an ultrasonic instrument housing.

[0079] The transmitting-receiving switching circuit, the transmitting-receiving multiplexing circuit and the ultrasonic transducer are connected in series in sequence, the transmitting circuit and the receiving circuit are respectively connected to the transmitting-receiving switching circuit, the ultrasonic transducer, the digital control processing chip, the transmitting-receiving multiplexing circuit, the transmitting-receiving switching circuit, the transmitting circuit, the receiving circuit and the USB interface circuit are all encapsulated in an ultrasonic instrument housing, the ultrasonic transducer is located at the front end of the ultrasonic instrument housing, the front end surface of the ultrasonic instrument housing is a coupling plane, and the USB interface circuit is located at the rear end of the ultrasonic instrument housing.

[0080] The low power module is provided with:

[0081] 1. A digital power supply is used to provide adaptive electric energy for the digital control processing chip, the transmit-receive switching circuit, the transmit circuit and the transmit-receive multiplexing circuit. The digital power supply is provided with a linear voltage regulator for protecting its voltage stability. The digital control processing chip, the transmit-receive switching circuit, the transmit circuit and the transmit-receive multiplexing circuit are respectively connected to the digital power supply.

[0082] 2. An analog power supply is used to provide adaptive electric energy for the transmitting and receiving multiplexing circuit and the receiving circuit. The analog power supply is provided with a linear voltage regulator for protecting its voltage stability. The transmitting and receiving multiplexing circuit and the receiving circuit are respectively connected to the analog power supply.

[0083] 3. An adjustable high-voltage DC converter is used to provide an adaptive high voltage for the transmitting circuit, and the transmitting circuit is connected to the adjustable high-voltage DC converter.

[0084] 4. An overcurrent protector is used to limit the current intensity provided to the digital power supply, the analog power supply and the adjustable high-voltage DC converter. The digital power supply, the analog power supply and the adjustable high-voltage DC converter are respectively connected to the USB interface circuit through the overcurrent protector.

[0085] The blood flow image obtained by the above-mentioned ultrasound device can be used as an image displayed on the color ultrasound spectrum mode interface of the present invention.

[0086] The color ultrasound spectrum mode interface of the present invention can generate instructions, which are sent to the ultrasound device through the processor of the present invention through the USB interface circuit, and the ultrasound transducer head of the ultrasound device is controlled by controlling the circuit and various functional modules of the ultrasound device to obtain the desired signal. Therefore, it can be understood that the color ultrasound spectrum mode interface of the present invention controls the ultrasound device, wherein the operation of the sampling tool in the interface is the control of the ultrasound device. Of course, some processing is not processed by the signal fed back by the ultrasound device, but by notifying the processor of the present invention to process and execute. That is to say, the instructions generated on the color ultrasound spectrum mode interface of the present invention are specifically executed by the ultrasound device hardware or by the software in the processor. They are allocated according to the processing workload and their own functions. Part of the work that the ultrasound device can handle can also be moved to the processor to complete, and the work that the processor has too much workload and is difficult to handle can also be handed over to the ultrasound device to complete.

[0087] Among them, the portable control terminal indicated by 1 in the figure is a device that can display the color ultrasound spectrum mode interface of the present invention, specifically a computer, smart phone, or tablet computer installed with software that can execute the method of the present invention.

[0088] Example 2:

[0089] A color ultrasound spectrum mode interface 11 is generated on the display screen 1 .

[0090] refer to Figure 3In the ultrasound color spectrum mode interface, there are other function area 14 virtual buttons, such as buttons for starting and closing the ultrasound interface, and buttons for exiting the ultrasound color spectrum mode interface. In particular, there is: a first button 10 for entering the blood flow spectrum display stage from the sampling preparation stage. After setting various parameters in the sampling preparation stage and adjusting the sampling work, click the first button 10, and the interface will enter the blood flow spectrum display stage interface 3 from the sampling preparation stage interface 2.

[0091] During specific implementation, the color ultrasound spectrum mode interface of the present invention has two modes, one is the sampling preparation mode, and the other is the blood flow spectrum display mode. These two modes are carried out in stages. In normal operation, to obtain a blood flow spectrum image, you must first operate in the sampling preparation stage interface 2, including adjusting the sampling tool. After the adjustment is completed, enter the blood flow spectrum display stage interface 3. Therefore, the present invention is referred to as the sampling preparation stage and the blood flow spectrum display stage. It can be regarded as that in the sampling preparation stage, the sampling range, direction, and various parameters of the pulse repetition frequency are mainly preset, while in the blood flow spectrum display stage, the output is performed according to the preset parameters.

[0092] Therefore, reference Figure 4 In the sampling preparation stage, there is a blood flow ultrasound image display area on the interface. The entire interface is occupied by the blood flow ultrasound image, which displays the vascular ultrasound image and multiple sampling tools for sampling the blood flow ultrasound image in range and direction. The sampling tools overlap with the blood flow ultrasound image. The sampling tools are some high-brightness lines or wireframes, which are more obvious on the vascular ultrasound image and easy to identify. Specifically, the sampling tools are some high-brightness colored lines or wireframes.

[0093] The sampling tool is described in detail below.

[0094] (1) Sampling frame 23: The sampling frame is located in the middle of the blood flow ultrasound image display area. The specific shape is a parallelogram. Inside the sampling frame is a colored area used to mark the blood vessel color ultrasound image. A section of the blood vessel 25 passes through the sampling frame, generally from the left to the right, and is displayed in color in the sampling frame, which helps to intuitively observe the basic situation of the blood vessel 25.

[0095] (2) Sampling volume tool 24: Located in the middle of the sampling frame 23, it is a pair of short parallel lines arranged horizontally, constituting a sampling volume tool; it is used to indicate the sampling volume in the blood vessel. The calculated volume refers to the volume of blood flow between the two parallel lines of the sampling volume. During the sampling process, in order to determine the required sampling position, the sampling volume tool needs to be moved. It moves on the longitudinal section plane in the blood vessel. When it is displayed on the blood flow ultrasound image, it moves on the blood vessel 25. The specific position of the movement is determined according to the doctor's needs.

[0096] (3) Blood flow direction tool 21: A line segment located between the parallel lines constituting the sampling volume is the first line segment. The first line segment is longer than the parallel lines constituting the sampling tool, and both ends extend from the gaps at both ends of the sampling volume (the sampling volume tool is a pair of horizontal parallel lines, and the two ends are similar to gaps). It is used to mark the blood flow direction. When working, the blood flow direction tool is parallel to the blood flow direction, approximately parallel to the blood vessel wall. Adjusting the blood flow direction tool is to change the marking of the blood flow direction, which will affect the output result of the blood flow spectrum. It may mean that the blood vessel on the blood flow ultrasound image is not in the same direction as the blood flow direction tool, and the two form a deflection angle. At this time, the user needs to operate to adjust the blood flow direction tool to make the blood flow direction tool parallel to the blood flow direction.

[0097] (4) Blood flow spectrum sampling line 22: It is a line segment (second line segment) that passes through the sampling frame vertically. When the ultrasound spectrum is working, the sample is a cross section in the blood vessel. The blood flow spectrum sampling line indicates which section on the blood vessel is specifically located. Moving the blood flow spectrum sampling line means moving the sampled section of the blood vessel.

[0098] During the sampling preparation stage, a plurality of sampling instruction receiving areas are generated at the first position where a part of the pixels of the sampling tool are located. Specifically, in the above-mentioned sampling tool, in order to operate each sampling task more conveniently and intuitively, a sampling instruction receiving area is generated on the sampling tool. Specifically, a first instruction receiving area 91 is set at the pixels at both ends of the first line segment constituting the blood flow direction tool, and at the positions of the nearby areas of the pixels at both ends; the instructions received by the first instruction receiving area are used to control the blood flow direction tool to deflect the blood flow direction tool, specifically, to control the first line segment to rotate the first line segment around the center, so as to artificially control the first line segment to be parallel to the blood vessel wall or parallel to the blood flow direction, so that the calculated blood flow spectrum parameter results are more accurate.

[0099] refer to Figure 5 In (a), one example is that the first instruction receiving area includes pixels at both ends of the first line segment, and no matter where the pixels at both ends of the first line segment move to the interface, the first instruction receiving area follows. Therefore, one example is that if the user inputs any pixel at both ends of the first line segment covered by the contact surface 13 of the finger tip, reference Figure 5 (b) in FIG. 1 is considered to be in the first instruction receiving area. One example is that when input is made with a mouse, any pixel at both ends of the first line segment touched by the mouse pointer is considered to be in the first instruction receiving area.

[0100] refer to Figure 5In (c), another example is that the first instruction receiving area includes pixels at both ends of the first line segment and the peripheral areas of the pixels at both ends of the first line segment. No matter where the pixels at both ends of the first line segment move to on the interface, the first instruction receiving area (including the peripheral areas) follows. When the first line segment rotates, the instruction area also follows the moving position. The position that originally belonged to the first finger field area is no longer the first instruction receiving area. When the first line segment moves to the current position, the current position that did not originally belong to the first instruction receiving area now becomes the first instruction receiving area. As for the size of the peripheral area, it depends on the screen size and there is no limit. For example, it can be set that the pixels within 100 pixels at both ends of the first line segment belong to the first instruction receiving area. Reference Figure 5 In (d), if any pixel of the first instruction receiving area is covered by the contact surface 13 of the user input finger, it is considered to be in the first instruction receiving area, or if more than 50% of the contact surface of the user input finger is covered by the contact surface, it is considered to be an instruction made in the first instruction receiving area. One example is that in the case of mouse input, any pixel of the first instruction receiving area touched by the mouse pointer is considered to be an instruction made in the first instruction receiving area.

[0101] When fingertip touch input is used, the touch display screen receives changes in the user's fingertip touch signal to form instructions, requiring the user to input the instruction at an accurate position. However, the area of ​​the user's fingertip is large, and the coverage range is difficult to accurately ensure that it is only at the two ends of the first line segment, or the mouse pointer is difficult to move to a precise position. The above two examples avoid this problem.

[0102] After the first instruction receiving area is determined, other positions of the first instruction receiving area are excluded, and the following multiple sampling instruction receiving areas are provided, in which the sampling range and pulse repetition frequency of the sampling tool can be changed.

[0103] refer to Figure 6 In (a), the portion at the bottom of the interface that occupies 1 / 3 of the area of ​​the interface is the second instruction receiving area 92, and the lower end of the sampling line runs through this area. Figure 6 When the pixels of the second instruction receiving area covered by more than 50% of the contact surface of the user's input fingertip are considered to be instructions made in the second instruction receiving area, and are used to move the cross-sectional sampling position of the blood flow spectrum sampling line on the blood vessel. If the pixels of the second instruction receiving area covered by more than 50% of the contact surface of the user's input fingertip are considered to be instructions made in the second instruction receiving area. One example is that when inputting with a mouse, any pixel of the second instruction receiving area touched by the mouse pointer is considered to be an instruction made in the second instruction receiving area.

[0104] refer to Figure 7 In (a), the third instruction receiving area 93 is located at the upper part of the interface, occupying 2 / 3 of the area of ​​the interface; it is divided correspondingly with the second instruction receiving area, the second instruction receiving area occupies 1 / 3 of the area of ​​the lower part of the interface, and the third instruction receiving area occupies 2 / 3 of the area of ​​the upper part of the interface. The 1 / 3 and 2 / 3 here are not fixed, and can be adjusted at will, for example, adjusted to 1 / 2 each. Figure 7 From the above, it can be seen that the third instruction receiving area excludes the part where the first instruction receiving area is located. The first instruction receiving area is actually surrounded by the third instruction receiving area. During operation, the two may affect each other. For example, the user intends to operate the first indication area, but the input touch surface is mostly covered in the third instruction receiving area. Therefore, in order to prevent this incident as much as possible, the area of ​​the first instruction receiving area should be expanded as much as possible. When the user intends to input in the first instruction receiving area, it is easier to cover the fingertip contact surface on the pixels of the first instruction receiving area. When the user intends to input in the third instruction receiving area, stay away from the first instruction receiving area as much as possible to avoid accidentally touching the first instruction receiving area. For the same reason, the area of ​​the first instruction receiving area should also be expanded as much as possible when inputting with a mouse pointer.

[0105] If part (even most) of the fingertip contact surface of the user input fingertip covers the third instruction receiving area, and another part (even a small part) of the fingertip contact surface covers the pixels of the first instruction receiving area, it should be considered that the instruction is made in the first instruction receiving area, not the third instruction receiving area. Therefore, the instructions considered to be made in the third instruction receiving area are only the following two situations:

[0106] 1. Reference Figure 7 In (b), when more than 50% of the contact surface 13 of the user input finger tip covers the third instruction receiving area, and another part of the contact surface of the finger tip covers the pixels of the second instruction receiving area, the instruction is considered to be made in the third instruction receiving area.

[0107] 2. The third instruction receiving area covered by the entire contact surface of the user's input fingertip is considered to be an instruction made in the third instruction receiving area.

[0108] Another embodiment is that it is not convenient to expand the priority of the first instruction receiving area too much, and it is limited that the first instruction receiving area covered by more than 50% of the contact surface of the user's input fingertip is regarded as an instruction made in the first instruction receiving area. Therefore, the instruction deemed to be made in the third instruction receiving area also includes a third situation: in any case, the third instruction receiving area covered by more than 50% of the contact surface of the user's input fingertip is regarded as an instruction made in the third instruction receiving area.

[0109] One example is that, in the case of mouse input, any pixel in the third instruction receiving area touched by the mouse pointer is considered to be an instruction made in the third instruction receiving area.

[0110] The third instruction receiving area is an instruction for moving the sampling position of the sampling volume tool.

[0111] refer to Figure 8 A fourth instruction receiving area 94 for changing the pulse repetition frequency value or the sampling volume size is set at any position on the left or right part of the interface.

[0112] One example is that a fourth command receiving area is set in the left 1 / 2 area of ​​the interface, and the command input in this part is used to change the sampling volume size.

[0113] One example is that a fourth instruction receiving area is set in the right 1 / 2 area of ​​the interface, and the instructions input in this part are used to change the pulse repetition frequency value.

[0114] One example is that either the left or right side can freely set one of the items of changing the sampling volume size and changing the pulse repetition frequency value, while the other item is set on the other side. In addition, the division of the left / right side of the interface does not necessarily have to be divided in half (each occupying 1 / 2 of the interface area), and the area can be divided freely.

[0115] A preferred example is that the fourth instruction receiving area for changing the pulse repetition frequency value is set in the left 1 / 2 area of ​​the interface, and the instruction input in this part is used to change the pulse repetition frequency value. The fourth instruction receiving area for changing the sampling volume size is set in the right 1 / 2 area of ​​the interface, and the instruction input in this part is used to change the sampling volume size.

[0116] Since the fourth instruction receiving area conflicts with the positions of the first, second, and third instruction receiving areas, the number of input contacts can be used to avoid misidentification of instructions and confusion. One example is that only under multi-touch 15, it is recognized as an instruction made in the fourth instruction receiving area. Multi-touch refers to other number touches excluding single-touch, for example, receiving two or more contact inputs in the fourth instruction area is regarded as multi-touch.

[0117] There is also a situation that in multi-touch, part of the fingertip contact surface is not accurately covered, for example, one of the fingertip contact surfaces is at the boundary between the left and right parts, or one of the fingertip contact surfaces is on the left and the other contact surface is on the right. This situation can be recognized as invalid input and no response is prompted; or it is preferably regarded as an instruction to change the size of the sample volume. Mouse pointer input does not apply to the fourth instruction receiving area.

[0118] In the ultrasound color spectrum mode interface, after adjusting the sampling work, click the first button 10, the interface changes from the sampling preparation stage to the blood flow spectrum display stage, and the interface also switches to the color spectrum mode interface 11, and outputs the calculation results according to the preset parameters in the sampling preparation stage, that is, outputs the blood flow spectrum diagram.

[0119] The color ultrasound spectrum mode interface 11 has: a blood flow ultrasound image display area 31 and a blood flow spectrum image area in parallel. One way of juxtaposition is left / right arrangement of the interface, with the blood flow ultrasound image display area on the left and the blood flow spectrum image area on the right. However, this display method is not conducive to viewing.

[0120] refer to Fig. 9 A preferred example is an up / down arrangement of the interface, with the upper part being the blood flow ultrasound image display area and the lower part being the blood flow spectrum image area. This method is convenient for viewing and can display more image information.

[0121] In this example, the blood flow ultrasound image completely occupies the blood flow ultrasound image display area. At the same time, there are multiple sampling tools in this area for sampling the blood flow ultrasound image in range and direction. The sampling tools overlap with the blood flow ultrasound image. The sampling tools are some high-brightness lines or wireframes, which are displayed on the vascular ultrasound image and are easy to identify. Specifically, the sampling tools are some high-brightness colored lines or wireframes, including: sampling frame 23, sampling volume tool 24, blood flow direction tool 21, blood flow spectrum sampling line 22. However, unlike the sampling preparation stage, the sampling tools are no longer operable and controllable in the blood flow spectrum display stage. All instruction receiving areas (in the interface) in the sampling preparation stage are closed and no longer receive instructions.

[0122] The lower blood flow spectrum image area at least displays the blood flow spectrum image horizontally from left to right, and the blood flow spectrum baseline 34 that runs through the blood flow spectrum image, and the position of the baseline can be adjusted up and down. The function of the baseline 34 is: since the blood flow spectrum image spectrum is divided into positive and negative directions, starting from the baseline, the part above the baseline is positive, and the part below is negative, and the baseline is zero, so adjusting the baseline up and down is actually adjusting the positive and negative display range. For example, if the upper part is positive and the lower part is negative, then when it is adjusted up, more negative components will be displayed, and then the positive components will be reduced. When the actual ultrasound outputs the image, the images in the positive and negative directions are not necessarily of the same height. Sometimes they are concentrated in the negative direction and the height is greater in the negative direction, while the height in the positive direction is very small, so it is necessary to display more of the negative part. Otherwise, the display will be reflected, and the image displayed in this way is incorrect. Therefore, the baseline needs to be manually adjusted up and down.

[0123] When entering the blood flow spectrum display stage, the sampling instruction receiving area needs to be closed synchronously. The original first to fourth instruction receiving areas are exited and no longer receive user input.

[0124] A blood flow spectrum image control instruction area is generated in each of the blood flow ultrasound image display area and the blood flow spectrum image area.

[0125] For the control of blood flow spectrum images, at least the following three parameters need to be controlled: one is the ultrasound signal gain adjustment, another is the baseline position, and the third is the spectrum speed.

[0126] Therefore, reference Fig.10 , an ultrasound signal gain adjustment instruction receiving area (hereinafter referred to as the fifth instruction receiving area 95) is generated in the blood flow ultrasound image display area, and a baseline position and spectrum velocity adjustment instruction receiving area (hereinafter referred to as the sixth instruction receiving area 96) is generated in the blood flow spectrum image area.

[0127] The fifth instruction receiving area and the sixth instruction receiving area are separated by the boundary line between the blood flow ultrasound image display area and the blood flow spectrum image area. The upper part is the fifth instruction receiving area and the lower part is the sixth instruction receiving area. When the pixels of the fifth instruction receiving area covered by more than 50% of the contact surface 13 of the user's input fingertip are considered to be instructions made in the fifth instruction receiving area, and are used to adjust the ultrasonic signal gain. One example is that when inputting with a mouse, any pixel of the fifth instruction receiving area touched by the mouse pointer is considered to be an instruction made in the fifth instruction receiving area.

[0128] When the pixels of the sixth instruction receiving area covered by more than 50% of the contact surface of the user's input fingertip are considered to be instructions made in the sixth instruction receiving area, and are used to adjust the baseline position or the spectrum speed; but whether to adjust the baseline position or the spectrum speed is determined by the number of contacts shown in other examples. By adjusting the spectrum speed, the distance between the spectrum waveforms can be widened, the distance between the peaks and troughs can be widened, the spectrum waveforms can be avoided from being too close, and the difficulty of identification, observation and calculation can be reduced. One example is that when using a mouse for input, the pixels of the sixth instruction receiving area touched by the mouse pointer are considered to be instructions made in the sixth instruction receiving area.

[0129] Example 3: How to operate the color ultrasound spectrum mode interface.

[0130] The color ultrasound spectrum mode interface of the present invention is displayed by a display screen 1, and the display screen 1 completes the interaction with the user. The method of inputting instructions is that the user slides on the interface, specifically by touching the color ultrasound spectrum mode interface with a finger or sliding a mouse pointer.

[0131] In the case of finger touch, there are different numbers of touch points, including single-point touch and multi-point touch 15. Single-point touch means that the display screen 1 receives the coordinates of one touch point, which comes from the user's single-finger operation; multi-point touch 15 means that the touch display screen receives the coordinates of more than one touch point, which comes from the user's two-finger operation or multi-finger operation.

[0132] The sliding of the mouse pointer is equivalent to single-point touch, and the mouse dragging action is used when operating the mouse, that is: after moving the mouse pointer to the corresponding instruction receiving area, press and hold the left mouse button, then move the pointer, and release the left mouse button after moving the required distance. In all examples of the present invention, especially the single-point touch instructions in the first to third instruction receiving areas, the fifth and sixth instruction receiving areas described in the following examples, understood as a single-finger fingertip touch, understood as a single-finger touch can be equivalent to describing the sliding of the mouse pointer. To avoid redundancy, examples of mouse pointer sliding input instructions are no longer described separately, but any single-point touch instructions in the first to third instruction receiving areas, the fifth and sixth instruction receiving areas, understood as a single-finger fingertip touch, understood as a single-finger touch can unanimously derive examples of mouse pointer sliding input instructions. The mouse pointer sliding input instruction is not applicable in the fourth instruction receiving area.

[0133] The sliding input here includes moving the sliding input track.

[0134] refer to Fig.11 The trajectory is the process of the user's fingertip continuously passing through pixel rows or pixel columns on the display screen 1, which is divided into a first direction 41, a second direction 42, a third direction 43, and a fourth direction 44.

[0135] The first direction 41 is a direction of reciprocating movement roughly parallel to the pixel columns in the interface, that is, a process of moving roughly downward from the top of the display screen 1, and a process of moving roughly upward from the bottom of the display screen.

[0136] The second direction 42 is a direction of reciprocating movement along the interface substantially parallel to the pixel row, that is, a process of moving roughly from the right side of the display screen to the right, and a process of moving roughly from the right side of the display screen to the upper left.

[0137] Among them, the third direction 43 is an arc-shaped movement roughly around the center of the interface. Here, the interface needs to be centered. Of course, the center of the currently operated tool can also be centered. Since the two tools that need to be operated in the third direction are also in the middle of the interface, the interface is centered, that is, the center of the called tool.

[0138] The fourth direction 44 is an irregular curved movement on the display screen.

[0139] refer to Figure 2, the operation methods of the color ultrasound spectrum mode interface are as follows.

[0140] S1: When using the color ultrasound spectrum mode, first enter the color ultrasound spectrum mode interface. The interface content refers to Example 2. The sampling preparation stage interface 2 is generated on the touch screen, and the blood flow ultrasound image and sampling tools are displayed to the user in the interface.

[0141] S2: Generate a sampling instruction receiving area.

[0142] S3: Receive the instruction input by the user in the sampling instruction receiving area, and adjust the sampling range, direction, and pulse repetition frequency of the sampling tool according to the instruction. The details are as follows:

[0143] (1) When a single-point touch command is received from the user in the first command receiving area 91, the blood flow direction tool is called. During the input command process, since the change of the blood flow direction tool is a rotational change, the user's input habit will also roughly follow the rotation of the first line segment, so the touch movement trajectory is along the third direction. The first command receiving area 91 is the pixels at both ends of the first line segment that forms the blood flow direction tool, and the location of the area near the pixels at both ends. When the user's fingertip touches this area, it is considered that the blood flow direction tool will be called, and an adjustment command will be issued for the direction of blood flow. When the fingertip touches the pixels at the right or left end of the first line segment and the vicinity, and rotates clockwise or counterclockwise, the first line segment also rotates clockwise or counterclockwise. Among them, the rotation angle can correspond to the touch movement trajectory. For example, if the touch movement trajectory has 500 pixels, the end of the first line segment also moves 500 pixels. The blood flow direction tool is adjusted by the above method to be the same as the blood flow direction.

[0144] (2) When a single-point touch command is received from the user in the second command receiving area 92, the blood flow spectrum sampling line is called. During the input command process, since the change of the blood flow spectrum sampling line is a rotational change, the user's input habit will also roughly follow the rotation of the second line segment, and the moving trajectory of the touch is along the third direction. The second command receiving area is located at the bottom of the interface. When the user's fingertip touches the second command receiving area, it is considered that an adjustment command will be issued to the position of the blood flow spectrum sampling line. When the fingertip touches the second command receiving area and rotates clockwise or counterclockwise, the first line segment also rotates clockwise or counterclockwise. Among them, the rotation angle can correspond to the moving trajectory of the touch. For example, if the moving trajectory has 500 pixels, the end of the first line segment also moves 500 pixels. The cross-sectional sampling position on the blood vessel is adjusted by the above method.

[0145] (3) When a single-point touch command from the user is received in the third command receiving area 93, the sampling volume tool is called, and the position of the sampling volume tool is changed, so that the sampling volume tool can move arbitrarily within a range of 360°, and thus the direction of movement is along the fourth direction. When the user's fingertip touches the third command receiving area, it is considered that an adjustment command will be issued for the position of the sampling volume tool.

[0146] When the fingertip touches the third command receiving area and moves arbitrarily, the sampling volume tool also moves synchronously, wherein the movement track and position can be matched one by one, for example, when the fingertip touches and moves 500 pixels to the upper right, the sampling volume tool also moves 500 pixels to the upper right. The position of the sampling volume tool in the longitudinal section of the blood vessel is adjusted by the above method.

[0147] (4) When a multi-touch command along the first direction is received from the user in the fourth command receiving area 94, a sampling volume tool is called to change the sampling volume size; or to change the pulse repetition frequency value.

[0148] It should be noted that the fourth instruction receiving area 94 covers the entire interface, and at least overlaps with the second instruction receiving area 92 and the third instruction receiving area 93. Whether it overlaps with the first instruction area is not important, because the area of ​​the first instruction area is relatively small and there are not many operation conflicts. This example sets the fourth instruction receiving area to overlap with the first instruction area. Of course, the second instruction receiving area and the third instruction receiving area do not overlap with each other. Therefore, when the user inputs, how to distinguish whether it is an input instruction in the fourth instruction receiving area or an input instruction in other instruction areas depends on the number of contacts. When the user's multi-point touch is received, the fourth instruction area responds to the input, and when the user's single-point touch is received, the first to third instruction receiving areas respond.

[0149] One example is that when a multi-touch instruction along the first direction is received from the user on the left side of the fourth instruction receiving area, the pulse repetition frequency value is changed. When the user's multi-touch trajectory is from bottom to top, the ultrasonic pulse repetition frequency is increased; when the user's multi-touch trajectory is from top to bottom, the ultrasonic pulse repetition frequency is reduced.

[0150] When receiving a multi-touch instruction from the user along the first direction on the right side of the fourth instruction receiving area, the sampling volume size is changed. When the multi-touch track of the user is from bottom to top, the sampling volume is increased; when the multi-touch track of the user is from top to bottom, the sampling volume is reduced.

[0151] S4: After the sampling tool is adjusted in the color Doppler spectrum mode interface, the sampling preparation phase interface 2 is switched to the blood flow spectrum display phase interface 3. The sampling instruction receiving area is closed. That is, the first to fourth instruction receiving areas are closed. Any operation on the interface will no longer control the sampling tool, and will no longer change the sampling range, direction, and pulse repetition frequency of the sampling tool.

[0152] Interface 3 of the blood flow spectrum display stage displays the blood flow ultrasound image and the blood flow spectrum image side by side to the user. The sampling tool is also displayed and overlaps with the blood flow ultrasound image, but is no longer controlled.

[0153] S5: Generate a blood flow spectrum image control instruction area in each of the blood flow ultrasound image display area and the blood flow spectrum image area.

[0154] S6: receiving the instructions input by the user in the blood flow spectrum image control instruction area, and changing the position of the blood flow spectrum baseline, as well as the ultrasound signal gain and spectrum speed according to the instructions. Specifically:

[0155] (1) When a single-point touch command is received from the user in the ultrasonic signal gain adjustment command receiving area, the ultrasonic signal gain function is called. Determine which direction the first direction is. When the user's multi-point touch track is from bottom to top, the gain is increased; when the user's multi-point touch track is from top to bottom, the gain is reduced. The gain is a time / distance compensation gain. Ultrasound has attenuation, and adjusting the gain to compensate for the attenuation can make the echo inside the organ consistent with the echo on the surface.

[0156] (2) When receiving a single-point touch command from the user in the spectrum speed adjustment command area, the baseline tool or the spectrum tool is called. Whether the baseline tool or the spectrum tool is called is determined by the user's moving trajectory in the command area. If the user's touch trajectory is in the first direction, it is regarded as calling the baseline tool, which will change the upper and lower positions of the baseline. The baseline moves up and down, and its moving distance and direction correspond to the moving distance and direction of the user's touch trajectory. For example, when the user's touch trajectory moves 300 pixels downward, the baseline also moves 300 pixels downward. When the user's touch trajectory moves 200 pixels upward, the baseline also moves 200 pixels upward.

[0157] If the user touches the track in the second direction, it is considered to adjust the spectrum speed. Whether the spectrum speed is accelerated or slowed down and the degree of change is determined according to the specific direction of the touch track. For example, the spectrum speed is preset with ten gears. When the user slides the input operation once and the touch track is to the left, the spectrum speed increases by one gear. From the image, the waveform of the blood flow spectrum becomes tighter and the spacing between the peaks becomes smaller. When the user slides the input operation once and the touch track is to the right, the spectrum speed slows down by one gear. From the image, the waveform of the blood flow spectrum becomes wider and the spacing between the peaks becomes larger.

[0158] After the above method is programmed with code, it is written into a readable storage medium, and this readable storage medium can be installed in any tablet computer or smart phone, so that this method can be implemented on the mobile phone.

[0159] Alternatively, after programming the above method with code, you can download the APP and install it on any tablet computer or smart phone, and then implement this method on the mobile phone.

[0161] In the above examples, each example has its own emphasis. If the complete content is not described in a certain example, it can be combined with the content shown in other examples.

[0163] Other technical solutions obtained without departing from the core idea of ​​the invention fall within the protection scope of the present invention.
