Function description:
 PHV power supply board is the board that provides the power to the transmitting circuit.
AP100V, AN100V, PHV1P, PHV1N, PHV2P, PHV2N, CW_PWR_P and CW_PWR_N are
all outputs.
 PHV output goes into the power supply by producing the circuit via LDO.
 PHV input goes into the main board after being filtered.
4.6 ECG Unit
ECG module is designed for monitoring ECG signals and displaying ECG waveforms, which
serves as reference of ultrasound images. This module can synchronize with 2D images and
color flow images in real-time display. With R wave detected, ECG signals, after being
