Figure 4-1Schematic Diagram of System
As a mobile color ultrasonic product，the system supports 3 probe sockets.
The detailed structure of the ultrasound system is in the figure above, and they can
be divided into 4 main modules:
 Main unit module
 Power supply module
 Monitor
 Control panel
The four modules will be described in the following chapters.
4.2 Main Unit Module
The main unit module contains 7 boards:
 Probe board
