一种超声设备的低功耗控制方法及系统
By automatically determining the probe's contact status through processing the power spectrum of the ultrasonic echo signal, the problem of high power consumption of ultrasonic equipment when it is not in contact with the human body surface is solved, thus achieving low power consumption control of the probe and improving imaging quality.

AI Technical Summary
Existing ultrasound equipment maintains high power consumption even when the probe is not in contact with the human body surface, resulting in energy waste and shortened equipment lifespan. At the same time, the lack of automated contact detection technology affects image quality.
By receiving and processing the power spectrum of the ultrasonic echo signal, it determines whether the probe is in contact with the human body surface, and controls the ultrasonic equipment to enter a low-power mode when there is no contact. This process includes transmitting ultrasonic pulse signals, quadrature demodulation, Fourier transform, and high-pass filtering.
It enables automated detection of probe contact status, improves imaging quality, saves energy, and extends equipment life.
