Basic Structure of HS70A
Overview
HS70A consists of the Ultrasound System Part and the User Interface Part. However, when
considered as an electronic structure, it consists of a Front End Part, a Back End Part, a User
Interface Part, and a Power Part. A description of HS70A as an electronic structure is as
follows:
Front End Part refers to the PSA (Probe Select Assembly), BF (Beamformer), and CW
(Continuous Wave Board). The main functions of the Front End Part are to deliver High
Voltage Pulser to the probe, thereby generating ultrasonic waves, and to amplify the returning
echo signal to process Digital Beamforming. The RF signal generated here is sent to the Back
End Part.
Back End Part refers to the BE (Back End) of the Ultrasound System Part as well as the PC
Module.
It generates various diagnostic images such as BW, Color Doppler, PW Doppler, Power
Doppler, etc. from the RF signal generated by the BF (Beamformer), and displays the images
on the monitor so that the user can view them. In addition, it incorporates new technologies
such as SCI and SDMR to facilitate a wide variety of diagnostic exams.
User Interface Part means the LCD monitor and control panel (including touch panel).
The Power Part can be divided as AC-DC Power Module and DC-DC Power Module; AC-DC
Power Module converts AC voltage into DC to supply power to DC-DC Power Module as well
as PC power of the PC part. DC-DC Power Module supplies voltage to boards of the
Ultrasound System, while the PC Power supplies voltage to the PC Part.
Ultrasound System Part
The main function of the Main Board is to implement the ultrasound data up to the stage
before Scan Converter. It performs some Front End Part and Back End Part functions. This
detects probes and sends system information and application information in accordance with
