[0064] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0065] One embodiment of the present invention provides a method and apparatus for adjusting the transmission bandwidth of an ultrasonic device, which can automatically calculate the current required transmission bandwidth based on operating parameters.

[0066] The ultrasonic device 10 in this embodiment can be a handheld ultrasonic testing instrument, which is small in size and easy to carry. In particular, it can consist of only a probe and some wires, and can be wirelessly connected to other external smart devices. Using the screen of the smart device as a display, the ultrasonic device 10 can emit and receive ultrasonic waves, and then form an image on the display. Figure 1 The diagram shows the connection between the ultrasound device 10, i.e. the probe, and the display terminal 20. The display terminal 20 and the ultrasound device 10 can transmit data wirelessly via Bluetooth or WiFi, so the ultrasound device 10 can be adapted to various display terminals 20.

[0067] The display terminal 20 can be a computer, mobile phone, tablet computer, etc. These devices have built-in displays and can also have applications installed, such as mobile phone apps. By operating the app, the operating parameters of the ultrasound device 10 can be controlled.

[0068] As described in the background section, ultrasound equipment 10 typically has multiple data channels and generates a very large amount of data. This places high demands on wireless data transmission. When the data volume is too large, wireless transmission may result in data loss, instability, and other problems. Therefore, this embodiment provides a method that can adaptively adjust the transmission bandwidth to meet the requirements of wireless transmission.

[0069] This invention provides two embodiments, wherein Embodiment 1 is for B mode and Embodiment 2 is an adaptive transmission bandwidth adjustment method designed for CF mode.

[0070] Example 1

[0071] The following is combined Figure 2a and 2b This invention describes a method for adjusting the transmission bandwidth of an ultrasonic device 10 provided in the first embodiment of the present invention. Although this application provides method operation steps as shown in the following embodiments or flowcharts, the execution order of steps in which there is no necessary causal relationship in the logical structure, based on conventional or non-creative labor, is not limited to the execution order provided in the embodiments of this application.

[0072] Specifically, such as Figure 2a As shown, in mode B, the method for adjusting the transmission bandwidth of the ultrasonic device 10 includes the following steps:

[0073] Step S11: The ultrasound device 10 operates in mode B;

[0074] Step S21: Obtain the current operating parameters, wherein the current operating parameters are the operating parameters of the ultrasound device 10 during scanning;

[0075] Taking a linear array as an example, the scan lines of a frame of an image are as follows: Figure 2b As shown, the current running parameters can obtain these parameters: Assuming there are a total of N scan lines from left to right, Z focal points, and the length of each scan line is L sampling points, each sampling point is represented by SByte, the current running parameters can also include the current interval Prt between adjacent scan lines.

[0076] Step S31: Calculate the required transmission bandwidth based on the current operating parameters;

[0077] Step S31 may specifically include:

[0078] Step S311: Calculate the data volume and frame interval of a frame image.

[0079] Step S312: The current required transmission bandwidth is equal to the amount of data in one frame of image divided by the frame interval.

[0080] Specifically, the data size of one frame = N*Z*L*S bytes, and the frame interval = N*Z*Prt. Therefore, the data bandwidth of mode B (in bytes / s) is:

[0081] Band = Data volume of one frame / Frame interval = (N*Z*L*S) / (N*Z*Prt) = L*S / Prt, (Formula 1).

[0082] In other words, it is not necessary to obtain the number of scan lines and the number of focal points.

[0083] Step S41: Compare the required transmission bandwidth with the bandwidth threshold. If the required transmission bandwidth is greater than the bandwidth threshold, continue with the following steps:

[0084] Step S51: Calculate the required interval between adjacent scan lines based on the current operating parameters, the current required transmission bandwidth Band, and the bandwidth threshold Threshold;

[0085] Specifically, the current running parameter in step S51 can be the current interval.

[0086] The required interval newPrt = Band / Threshold * Prt, (Formula 2)

[0087] Band can be calculated using Formula 1.

[0088] Step S61: Adjust the interval between adjacent scanning lines of the ultrasound device 10 to the required interval newPrt.

[0089] Additionally, step S71 may be included: if the required transmission bandwidth is not greater than the bandwidth threshold, then the current operating parameters are maintained.

[0090] Example 2

[0091] The following is combined Figure 3a and 3b This invention describes a method for adjusting the transmission bandwidth of an ultrasonic device 10 according to a second embodiment of the present invention. Although this application provides method operation steps as shown in the following embodiments or flowcharts, the execution order of steps in which there is no necessary causal relationship in the logical process, based on conventional or non-creative labor, is not limited to the execution order provided in the embodiments of this application.

[0092] like Figure 3a As shown, in CF mode, the method for adjusting the transmission bandwidth of the ultrasonic device 10 includes the following steps:

[0093] Step S12: The ultrasound device 10 operates in CF mode;

[0094] CF mode is a duplex mode, which includes single-B mode and single-CF mode.

[0095] Step S22: Obtain the current operating parameters, wherein the current operating parameters include the first operating parameters in single B mode and the second operating parameters in single CF mode;

[0096] Step S32: Calculate the required transmission bandwidth based on the current operating parameters;

[0097] Step S32 specifically includes:

[0098] Step S321: Calculate the first data quantity Frame_B and the first frame interval Interval_B of a frame image in single-B mode according to the first running parameters; wherein, the first data quantity Frame_B and the first frame interval Interval_B can be calculated according to the method in Embodiment 1, Frame_B=N*Z*L*S Byte, Interval_B=N*Z*Prt.

[0099] Step S322: Calculate the second data quantity Frame_CF and the second frame interval Interval_CF of a frame image in single CF mode according to the second running parameters.

[0100] Taking a linear array as an example, the scan lines of a color image frame are as follows: Figure 3b As shown, the second operating parameters include N scan lines, M data packets, an interval of Prt between adjacent data packets, a length of L sampling points for each scan line, and each sampling point is represented by S bytes.

[0101] Then the second data size of a color image frame, Frame_CF, is N*M*L*S bytes, and the second frame interval, Interval_CF, is M*Prt.

[0102] The current required transmission bandwidth in CF mode is:

[0103] Band=(Frame_B+Frame_CF) / (Interval_B+Interval_CF), (Formula 3).

[0104] Step S42: Compare the required transmission bandwidth with the bandwidth threshold. If the required transmission bandwidth is greater than the bandwidth threshold, continue with the following steps:

[0105] Step S52: Calculate the required interval newPrt between adjacent scan lines in single-B mode based on the current operating parameters and bandwidth threshold;

[0106] In step S52, the interval Prt between adjacent data packets in single CF mode remains unchanged, while only the current interval Prt between adjacent scan lines in single B mode is changed.

[0107] The bandwidth threshold is Threshold. Calculating the required interval between adjacent scan lines in single-B mode includes:

[0108] newPrt=((Frame_B+Frame_CF) / Threshold-Interval_CF) / (N*Z), (Formula 4).

[0109] Step S62: Adjust the interval between adjacent scan lines in the single-B mode of the ultrasound device 10 to the required interval newPrt.

[0110] Additionally, step S72 may be included: if the required transmission bandwidth is not greater than the bandwidth threshold, then the current operating parameters are maintained.

[0111] Compared with the prior art, embodiments 1 and 2 have the following beneficial effects:

[0112] By applying the transmission bandwidth adjustment method of the ultrasound device 10, the required transmission bandwidth can be automatically calculated based on the operating parameters. When the required transmission bandwidth exceeds the bandwidth threshold, the bandwidth can be limited by reducing the frame rate to achieve a suitable value and meet the current bandwidth requirements. This successfully solves the problems of insufficient bandwidth and unstable wireless transmission in the handheld ultrasound detection system, bringing a better customer experience to the wireless handheld ultrasound imaging system.
