Module 2 System Hardware and Theory
The goal of the System Hardware and Theory Module is to provide
you with a solid grounding on the purpose of the GE Voluson E10
system’s different components and how they function together
within the system.
The three major functional blocks in all ultrasound systems are:
 Front End – Includes transducer analog signal processing
functions.
 Back End – Includes user interface and system communication
with DICOM systems.
 Power Systems – Generates, regulates and supplies the required
voltages to the various parts of the system.
Signal Flow
System configurations (GE dataflows) are stored on a hard drive
inside the BEP, and all the necessary software is loaded from the hard
drive on power up of the system.
The transmit bursts are routed from the RF interface to the relays
where the ultrasound probes are connected. The signals are
transmitted by the probes as ultrasound into the body. The input
signals travel from the probe connector panel to the Front End
Processor (FEP), then to the Back End Processor (BEP) for digital signal
processing(DSP) and finally, the results are displayed on the monitor.
