System Front End Components 
This section covers system frontend topics for the GE Logiq E9/Vivid 
E9. Front end is a general term for the parts of the ultrasound system 
that receive the reflections from acoustic energy that have been 
transmitted into the body and perform the various signal processing 
functions on them needed to produce an ultrasound image. The 
following are some of the components and functions that are found 
in a typical ultrasound system front end: 
 Transducers – Transmit focused acoustic energy and receive the 
resultant reflections. 
 High voltage switches – Used for multiplexing (connects a 
particular transducer element to a particular transmitter/receiver 
pair) 
 High voltage transmitters – Transmit analog data from the 
transducers. 
 Time Gain Control Amp (TGC) – A variable gain amplifier (VGA) is 
used to compensate for image variations due to tissue depth. 
 Analog to Digital converter and noise filtering. 
 Digital Beamformers – Upconverts signals which increases 
sample rates. The signals are stored in memory, apodized and 
summed. 
 Beamformed Digital Signal Processing – The digital beamformed 
signals received are processed into visual and audio outputs the 
process of which depends on if the transducer is B-mode (2D), 
Doppler, PWD or CWD. 
The front end manages the input from the transducers, performs 
Analog to Digital conversion, Digital to Analog conversion along with 
many other signal processing functions. 
E9 Front End Processor (FEP) 
In the GE E9 systems the card cage that contains the front end 
electronics is referred to as the FEP. Different versions of the systems 
have different board configurations. See the “GE Logiq E9 / Vivid E9

Platform Hardware Revisions” Section in the presentation that 
accompanies this manual for details on specific configurations. 
 XD_BUS: TOP Plane (Two boards used). 
 GRLY: Global (GECKO) Relay Board. 
 GRX64 w/ CW: Global Receiver Board 64 channel. 
 GRX128 / GRX128 w/ CW: Global Receiver Board 128 channel. 
 GTX: Global Transmitter Board. 
 DRX: Digital Receiver Board. 
 GFI: Global Radio Frequency Interface Board. 
 MRX: Multi Receiver Board (BT 2011 Logiq E9 only). 
 PDP: Power Distribution Panel Board (BT 2011 Logiq E9 only). 
 
The MRX Board combines the functionality of the Digital Receiver 
Boards (DRXs), Analog Receiver Boards (GRXs) and the Global Front 
End Interface (GFI)  
 
Power Distribution PD The function of power distribution was 
previously supplied from DRX Boards.The Power Distribution Board 
replaces all power supplies previously present in DRX and GRX 
Boards, plus the monitoring circuitry for the card rack fan control. 
Front End Signal Flow 
The GTX boards generate the signals that are transmitted to the 
probes to generate ultrasound energy into the body. The transmit 
pulses are routed from the GTX board via the XD bus to the relay 
board (GRLY) where the ultrasound probes are connected. 
The reflected ultrasound from the body structures are detected by 
the probes and converted into tiny electrical pulses. Those pulses are 
routed via the Relay board to the XD bus and sent to the RX boards. 
The GRX/MRX boards amplify the received signals. These signals are 
then routed to the DRX/MRX boards where the signals undergo signal 
processing such as A/D conversion. The processed signals are then 
transferred via the PCIe bus to the Back End Processor(BEP). 
The BEP receives input commands from the Operator Panel (OP) and 
handles the communications with the rest of the system. The BEP 
delivers digital video signals to the LCD monitor, Touch Screen, 
optional internal Digital Video Recorder, and an optional internal 
printer. The Back End Processor also handles all communications to

and from the network (Ethernet). 
 
 
System Backend Components 
This section describes the System Back End topics for the GE Logiq 
E9/Vivid E9. The back end includes system blocks/components on the 
user interface side that perform functions such as master controller, 
signal processing, image memory, video layout, peripherals and user 
interface. 
Back End Processor (BEP) 
The Back End Processor (BEP) unit receives the data from the FEP 
electronics, stores it in memory, performs scan conversion to the 
pixel domain, and drives the system’s monitors. 
Contains the HDD that holds the Base Image (Windows XP Embedded) 
and Application Software (System Specific). The BEP software also 
processes the Color Flow, Doppler, M-Mode data and the 3D/4D data.  
The BEP is physically located in the left side of the system. 
The main component of the BEP is the uBTX motherboard along with 
these major components: 
Front End Signal 
Flow MRX 
Configuration 
The BEP is system specific 
i.e. LE9 BEP vs. VE9 BEP 
are not interchangeable 
nor compatible with each 
other.

 BEP Power Supply 
 I/O Board 
 HDD -- 160GB Hard Drive 
 ADD Video Card for DVI 
 DVR Card (Optional) 
 Front Panel LEDs, etc. 
 Battery Pack 
 Graphics Adaptor 
 
The BEP interconnects with the following parts of the system: 
 FEP card rack for signal processing, controls, and loading scan 
parameters. 
 Top console for Operator Panel (UOP and LOP) and LCD for video 
out. 
 Main Power Supply unit, to configure, communicate and control 
MPS outputs. 
 Controls the rest of the system based on user input from 
Operator Panel. 
The following BEP models have been used for Vivid E9: 
 BEP6 was introduced in manufacturing in October 2012. The 
BEP6 is also called BEPY3. 
 BEP5 was introduced at the introduction of VIVID E9 and was 
phased out of manufacturing in October-November 2012. The 
BEP5 is also referred to as BEPY1 or BEPY2, depending on the 
installed System Software version.

The BEP6 I/O Board has two connectors for connection to the BEP6 
Motherboard. 
The BEP5 I/O Board has one connector for connection to the BEP5 
Motherboard. 
IO Board 
The IO Board interfaces between the BEP and: 
 The connectors on the rear side of Vivid E9 (video/audio/USB)

Patient I/O Module  
The Patient I/O module allows ECG inputs to be used in conjunction 
with patient studies. The scanned image that is displayed is 
synchronized with the ECG and PCG traces. In Doppler or M-Mode, 
the traces are synchronized to that particular mode’s sweep. The AUX 
input is capable of handling external ECG signals from other 
diagnostic ECG devices. 
 
Touch Screen 
The control panel touch screen enables access to different modes. 
The mode/function controls are organized in tabbed folders with 
potentially several pages within each folder. 
The five buttons at bottom of the touch panel are both rotary and 
push buttons. The functionality of these buttons changes, based on 
the current mode/function. 
Inputs for the patient I/O 
are not meant for patient 
monitoring they are 
meant for correlation with 
patient scans only.
