1.3.1 The instrument working principle as shown in figure 1-2
1.3.2 Briefly principle
1) The digital scanning conversion controls the scanning transmission and receiving of ultrasonic wave.
Image storage and display, user interface management, display mode conversion, annotation
measurement, etc.; Press the key on the control panel and the digital scanning conversion can respond
and send out kinds of control commands.
2) Send command emission circuit to receive the digital conversion, produce the high voltage pulse
probe emission need.
3) The probe driven by the high voltage will change the electric signal into ultrasonic vibration, and
the ultrasonic wave is transmitted into human body.
4) The ultrasonic wave produces the reflection signal in the body, then the probe will change it into
electric signal and send to ultrasonic receiver.
5) The ultrasonic receiver will magnify compression detection the electrical signal.
6) The digital scanning converter transforms the simulated signal into digital signal and memorizes the
received signal in the image memory synchronized with the ultrasonic wave scanning. And the
synchronized signal reads the signal in the image memory and transforms the simulated signal to
displayer and makes the ultrasonic wave image display on the screen.
