The B-Ultrasound Diagnostic System of six functional modules: Power module, Ultrasound front-end module, Keyboard module, Industrial control board, LCD screen, and Interface board. When electrical pulses are applied to the piezoelectric wafer (transducer), it will produce ultrasound waves of a certain frequency, which will enter the human body. Due to the ultrasound waves traveling through different tissues in the human body with different acoustic impedances (caused by differences in density and ultrasound transmission speed), the reflected echoes generated by the surfaces of different organs in the human body will be different. The reflected echoes of different sizes will be received by the piezoelectric wafer, and then converted into electrical pulse signals.
