[0039] In the embodiments of the present application, the memory 107 of the ultrasonic device 10 can be a flash memory card, a solid-state memory, a hard disk, or the like.

[0040] In the embodiments of the present application, a computer readable storage medium is also provided, which stores a plurality of program instructions. After the plurality of program instructions are called and executed by the processor 105, some steps or all steps or any combination of steps in the ultrasonic imaging method in the embodiments of the present application can be executed. The computer readable storage medium can be the memory 107, which can be a flash memory card, a solid-state memory, a hard disk, or the like, which is a non-volatile storage medium.

[0041] In the embodiments of the present application, the processor 105 of the ultrasonic device 10 can be implemented by software, hardware, firmware, or a combination thereof, and can use a circuit, a single or multiple application specific integrated circuits (ASICs), a single or multiple general-purpose integrated circuits, a single or multiple microprocessors, a single or multiple programmable logic devices, or a combination of the foregoing circuits or devices, or other suitable circuits or devices, so that the processor 105 can execute the corresponding steps of the ultrasonic imaging method in the embodiments of the present application.

[0042] In the embodiment, the processor 105 is configured to: acquire a first speed measurement range corresponding to a first imaging parameter, the first speed measurement range being a maximum speed measurement range corresponding to the first imaging parameter; when a maximum speed of an adjusted speed measurement range is greater than a maximum speed of the first speed measurement range, adjust the first imaging parameter to a second imaging parameter to obtain a second speed measurement range corresponding to the second imaging parameter; and the maximum speed of the second speed measurement range is greater than the maximum speed of the first speed measurement range.

[0043] Specifically, referring to FIG. 1, Figure 2 An embodiment of the method for adjusting the speed measurement range based on the ultrasonic Doppler in the embodiment includes the following steps.

[0044] 201. Acquire a first speed measurement range corresponding to a first imaging parameter, the first speed measurement range being a maximum speed measurement range corresponding to the first imaging parameter.

[0045] In the embodiment, the first imaging parameter is a preset imaging parameter of the ultrasonic device when the ultrasonic device is shipped, the first imaging parameter corresponds to a displayed speed measurement range of the ultrasonic device, and the first speed measurement range is a maximum speed measurement range corresponding to the first imaging parameter. In an example, the speed measurement range of the ultrasonic device can be displayed as three gears on a panel, gears A (10 mm / s to 20 mm / s), gear B (20 mm / s to 40 mm / s), and gear C (40 mm / s to 60 mm / s), and the gear C is the first speed measurement range in the embodiment. It should be noted that this is only an example and does not limit the value of the speed measurement range. Figure 3

[0046] 202. When a maximum speed of an adjusted speed measurement range is greater than a maximum speed of the first speed measurement range, adjust the first imaging parameter to a second imaging parameter to obtain a second speed measurement range corresponding to the second imaging parameter, and the maximum speed of the second speed measurement range is greater than the maximum speed of the first speed measurement range.

[0047] If the user finds that the speed measurement range displayed on the panel of the ultrasonic device cannot meet the speed measurement requirement (i.e., the maximum speed of the adjusted speed measurement range is greater than the maximum speed of the first speed measurement range) during the detection of the ultrasonic device, the ultrasonic device adjusts the first imaging parameter to a second imaging parameter to obtain a second speed measurement range corresponding to the second imaging parameter, and the maximum speed of the second speed measurement range is greater than the maximum speed of the first speed measurement range.

[0048] ​In this embodiment, the imaging parameter includes an imaging frequency point and an imaging depth, and the first imaging parameter includes a preset imaging frequency point and a preset imaging depth. The ultrasonic device adjusts at least one of the imaging parameter to the second imaging parameter. The specific operation is as follows:

[0049] In one possible implementation, the ultrasonic device reduces the preset imaging depth in the first imaging parameter to a first imaging depth, so that the velocity measurement range reaches the second velocity measurement range.

[0050] In another possible implementation, the ultrasonic device reduces the preset imaging frequency point in the first imaging parameter to a first imaging frequency point, so that the velocity measurement range reaches the second velocity measurement range.

[0051] In another possible implementation, the ultrasonic device reduces the preset imaging depth in the first imaging parameter to a first imaging depth, and obtains the velocity measurement range at this time. If the first imaging depth is reduced to a first preset threshold, and the velocity measurement range still does not reach the required velocity measurement range after adjustment, the ultrasonic device reduces the preset imaging frequency point in the first imaging parameter to a first imaging frequency point, so that the velocity measurement range reaches the second velocity measurement range.

[0052] In another possible implementation, the ultrasonic device reduces the preset imaging frequency point in the first imaging parameter to a first imaging frequency point, and obtains the velocity measurement range at this time. If the first imaging frequency point is reduced to a second preset threshold, and the velocity measurement range still does not reach the required velocity measurement range after adjustment, the ultrasonic device reduces the preset imaging depth in the first imaging parameter to a first imaging depth, so that the velocity measurement range reaches the second velocity measurement range.

[0053] In the embodiment of the present application, when the velocity measurement range adjusted by the ultrasonic device exceeds the physical limit of the fixed imaging frequency point and the fixed imaging depth, the imaging frequency point and / or the imaging depth can be reduced according to the Doppler law, so as to expand the velocity measurement range.

[0054] For details, please refer to Figure 4 In the embodiment of the present application, one embodiment of the velocity measurement range adjustment method based on ultrasonic Doppler includes:

[0055] 401、Obtain a first velocity measurement range corresponding to a first imaging parameter, wherein the first velocity measurement range is a maximum velocity measurement range corresponding to the first imaging parameter.

[0056] In this embodiment, the first imaging parameter is an imaging parameter preset when the ultrasonic device is shipped, the first imaging parameter corresponds to the velocity measurement range displayed on the ultrasonic device, and the first velocity measurement range is a maximum velocity measurement range corresponding to the first imaging parameter. In one example, the velocity measurement range of the ultrasonic device can be as shown in Figure 3As shown, three gears are displayed on the panel, namely gear A (10 mm / s to 20 mm / s), gear B (20 mm / s to 40 mm / s) and gear C (40 mm / s to 60 mm / s), and the gear C is the first speed range in the embodiment. It should be noted that the above is only an example and does not limit the value of the speed range.

[0057] 402、When the maximum speed of the adjusted speed range is greater than the maximum speed of the first speed range, the first imaging parameter is adjusted to the second imaging parameter to obtain a second speed range corresponding to the second imaging parameter, wherein the maximum speed of the second speed range is greater than the maximum speed of the first speed range.

[0058] When the user finds that the speed range displayed on the panel of the ultrasound device cannot meet the speed requirement during the detection of the ultrasound device (i.e., the maximum speed of the adjusted speed range is greater than the maximum speed of the first speed range), the ultrasound device adjusts the first imaging parameter to the second imaging parameter to obtain a second speed range corresponding to the second imaging parameter, and the maximum speed of the second speed range is greater than the maximum speed of the first speed range.

[0059] In the embodiment, the imaging parameter includes an imaging frequency point and an imaging depth, and the first imaging parameter includes a preset imaging frequency point and a preset imaging depth. The ultrasound device adjusts at least one of the imaging parameters by adjusting the first imaging parameter to the second imaging parameter. The specific operation is as follows:

[0060] In one possible implementation, the ultrasound device reduces the preset imaging depth in the first imaging parameter to a first imaging depth to make the speed range reach the second speed range.

[0061] In another possible implementation, the ultrasound device reduces the preset imaging frequency point in the first imaging parameter to a first imaging frequency point to make the speed range reach the second speed range.

[0062] In another possible implementation, the ultrasound device reduces the preset imaging depth in the first imaging parameter to a first imaging depth and obtains the speed range at this time. If the first imaging depth is reduced to a first preset threshold and the speed range still does not reach the required speed range, the ultrasound device reduces the preset imaging frequency point in the first imaging parameter to a first imaging frequency point to reach the second speed range.

[0063] In another possible implementation, the ultrasound device reduces the preset imaging frequency in the first imaging parameter to the first imaging frequency and obtains the speed measurement range at this time; if the first imaging frequency is reduced to the second preset threshold, and the speed measurement range still does not reach the speed measurement range required for adjustment, the ultrasound device reduces the preset imaging depth in the first imaging parameter to the first imaging depth to reach the second speed measurement range.

[0064] In one exemplary embodiment, assuming the factory-preset imaging parameters of the ultrasound device are an imaging frequency of 10 MHz and an imaging depth of 18 cm, the corresponding maximum velocity range is 10 mm / s to 60 mm / s. When the adjusted velocity range is 50 mm / s to 70 mm / s, the ultrasound device reduces the imaging frequency from 10 MHz to 8 MHz, thus achieving a velocity range of 50 mm / s to 70 mm / s. Assuming the minimum imaging frequency is 5 MHz, when the adjusted velocity range is 70 mm / s to 80 mm / s, reducing the imaging frequency to 5 MHz, if the velocity range still does not reach 70 mm / s to 80 mm / s, the ultrasound device can further reduce the imaging depth, for example, from 18 cm to 10 cm.

[0065] 403. When the maximum speed of the adjusted speed measurement range is less than the maximum speed of the first speed measurement range, adjust the second imaging parameter to the first imaging parameter to obtain the first speed measurement range.

[0066] If, during the ultrasound equipment testing process, the user finds that the speed measurement range displayed on the ultrasound equipment panel can meet the speed measurement requirements (i.e., the maximum speed measurement of the adjusted speed measurement range is less than or equal to the maximum speed measurement of the first speed measurement range), the ultrasound equipment adjusts the second imaging parameter to the first imaging parameter, thereby restoring the first speed measurement range.

[0067] In one exemplary embodiment, the factory-preset imaging parameters of the ultrasound device are assumed to be an imaging frequency of 10 MHz and an imaging depth of 18 cm, corresponding to a maximum velocity range of 10 mm / s to 60 mm / s. When the adjusted velocity range is 50 mm / s to 70 mm / s, the ultrasound device reduces the imaging frequency from 10 MHz to 8 MHz, thus achieving a velocity range of 50 mm / s to 70 mm / s. After adjusting the imaging parameters to an imaging frequency of 8 MHz and an imaging depth of 18 cm, when the adjusted velocity range is 20 mm / s to 50 mm / s, the ultrasound device restores the imaging frequency from 8 MHz to 10 MHz.

[0068] In the embodiment, when the velocity measurement range exceeds the physical limit of the fixed imaging frequency and the fixed imaging depth, the imaging frequency and / or the imaging depth can be reduced according to the Doppler law, so as to expand the velocity measurement range.

[0069] For details, please refer to Figure 5 An embodiment of the method for adjusting the velocity measurement range based on the ultrasound Doppler in the embodiment is shown in the following.

[0070] 501. Obtain a first velocity measurement range corresponding to a first velocity baseline, the first velocity measurement range being a maximum velocity measurement range corresponding to the first velocity baseline.

[0071] In the embodiment, the first velocity baseline is preset when the ultrasound device is shipped, the first velocity baseline corresponds to the displayed velocity measurement range of the ultrasound device, and the first velocity measurement range is a maximum velocity measurement range corresponding to the first velocity baseline. In an exemplary scheme, when the velocity baseline of the ultrasound device is 0, the velocity measurement range can correspond to 60 millimeters per second to -60 millimeters per second.

[0072] 502. When the maximum velocity measurement of the adjusted velocity measurement range is greater than the maximum velocity measurement of the first velocity measurement range, adjust the first velocity baseline to a second velocity baseline to obtain a second velocity measurement range corresponding to the second velocity baseline, wherein the maximum velocity measurement of the second velocity measurement range is greater than the maximum velocity measurement of the first velocity measurement range.

[0073] If the user finds that the displayed velocity measurement range on the panel of the ultrasound device cannot meet the velocity measurement requirement during the detection process of the ultrasound device (i.e., the maximum velocity measurement of the adjusted velocity measurement range is greater than the maximum velocity measurement of the first velocity measurement range), the ultrasound device adjusts the first velocity baseline to a second velocity baseline to obtain a second velocity measurement range corresponding to the second velocity baseline, and the maximum velocity measurement of the second velocity measurement range is greater than the maximum velocity measurement of the first velocity measurement range.

[0074] In this embodiment, the speed baseline corresponds to the velocity measurement range including two directions, i.e., a positive direction and a negative direction. When the ultrasound device needs to increase the velocity measurement range, the ultrasound device can increase the speed baseline in the respective direction. In an exemplary scheme, if the ultrasound device needs to increase the velocity measurement range in the positive direction, the ultrasound device can increase the speed baseline in the positive direction. For example, the first speed baseline is 0, the velocity measurement range is (-60 mm / s, 60 mm / s), and if the ultrasound device needs to increase the velocity measurement range to 80 mm / s in the positive direction, the speed baseline can be adjusted to 20 mm / s, and at this time, the velocity measurement range is (-40 mm / s, 80 mm / s). If the ultrasound device needs to increase the velocity measurement range in the negative direction, the ultrasound device can increase the speed baseline in the negative direction. For example, the first speed baseline is 0, the velocity measurement range is (-60 mm / s, 60 mm / s), and if the ultrasound device needs to increase the velocity measurement range to -80 mm / s in the negative direction, the speed baseline can be adjusted to -20, and at this time, the velocity measurement range is (-80 mm / s, 40 mm / s).
