Problems solved by technology

In terms of hardware, in order to improve the imaging resolution, a dense array of ultrasonic probes is often used. Since the signal of each ultrasonic probe needs to be amplified and processed in the application, the complexity and cost of the circuit design are increased.

The resolution improvement in the software is mainly through the interpolation algorithm to insert the estimated value into the actual detection image to improve the resolution, but the method based on the interpolation imaging will bring the distortion of the overall imaging, and the detection accuracy is not high
