4-2 Product Principle
âš« The management functions of the probe decouple the transmitting/receiving channel, and
communicate with the engine board.
âš« As the independent sub-module, 4D driving function and physiological signals are
subordinate to the engine board.
âš« As an option, CW receiving function can be realized through an independent single board
and is subordinate to TRA board signal.
â—¼ Back-end unit: more functions are achieved on back-end unit. It basically resembles with PC. It
is equipped with main functions of the main unit, calculation capacity of image post-process,
operator-system interface to human-computer interaction, etc. PC module takes charge of
back-end unit. The elements are shown above.
â—¼ Power supply unit: it supplies the power to the front-end unit, back-end unit and peripherals.
Other elements are shown above.
