Power from the wall outlet (100 to 240 VAC, 50/60 Hz) is connected 
to the Main Power Supply. The MPS delivers the needed voltages to 
the rest of the Logiq E9/Vivid E9: 
 Internal Peripherals (110-115 VAC) 
 Front End Rack (DC power with several voltages) 
 Front End Rack (TXPSV1 and TXPSV2 for the transmitters) (TSV1 
and TSV2 for the transmitters) 
 Front End Rack (PMXVOUT for the probe channel multiplexers) 
 Back End Processor (48 VDC) 
 Operator Panel, LCD, XYZ motors (48 VDC) 
When the system is switched on an inrush current limiter reduces the 
peak input current. The power supply also contains an EMI filter to 
reduce EMI to acceptable levels. The power supply contains 15 Amp 
fast acting ceramic fuses (only to be replaced by the manufacturer). 
Temperature Control 
The MPS is equipped with an internal variable speed fan to provide 
temperature control. The temperature of the air entering the power 
supply and leaving the power supply are monitored. The fan speed is 
adjusted according to temperature monitored by sensors. 
Power Down Sequences 
There are three possible scenarios for power shut down of the unit: 
 Normal Power Shut Down 
 Forced Power Shut Down 
 Unexpected Power Loss 
Normal Power Shut Down Sequence 
Press the ON/OFF button (for a short time) 
1. BEP detects the contact of Power (ON/OFF) switch. 
2. PSON_N goes high. This triggers the Main Power Supply to shut 
down the output voltages. 
3. Controller ACFAIL_N output signal goes low. 
4. Controller TS_OK output signal goes low. 
5. Controller turns OFF the TS (Transmit) voltages. 
6. Controller turns OFF the PMX (Probe MUX) voltages. 
7. Controller turns OFF voltages +/-15, +/-6, +11V, +24V.

8. ACFAIL_N output signal goes high. 
9. Controller turns OFF +48V. 
 
1. BEP detects short-term contact of Power Switch. 
2. BEP OS dialog box prompts user for power down. 
3. BEP, via PCI express, commands the GFI or MRX to stop scanning, 
disconnect TX circuits from TS, stop strobe TS_ON_STRB. 
4. BEP, via USB, commands Power Supply to shutdown TSV1 and TSV2 
(SetTxPS 0x68). 
5. Controller turns OFF PMX voltages. 
6. BEP, via USB, commands Power Supply to shutdown card rack 
(RackPower 0x6A). 
7. BEP OS performs shutdown. 
8. BEP sends PSON_N high to Power Supply. 
9. Controller turns OFF TS voltages. 
10. Controller TS_OK output signal goes low. 
11. Controller turns OFF PMX voltages. 
12. Controller turns OFF voltages +/-15, +/-6, +11V, +24V. 
13. Controller turns OFF +48V. 
14. Controller output 48V_OK goes low. 
 
Forced Power Shut Down 
Forced Power Down is initiated by depressing the ON/OFF button on 
the keyboard for a few seconds, until the power down sequence 
starts. 
Unexpected Power Loss 
A power loss may be due to: 
 The Mains Switch has been switched to OFF 
 The Mains cable has been disconnected 
 Brown-out or power loss (burnout) 
If a power loss (or error) occurs, all power distribution within the unit 
is lost. 
Logiq E9 Shut 
Down 
In case of total lockup of 
the system, hold the 
ON/OFF button down a 
few seconds to shut the 
system down.  
This shut down sequence 
will typically be less than 1 
second from the power 
failure is detected to all 
voltages have been shut 
down.

Module 3 Operating Modes 
The following general operating modes are available on E9 systems:  
B-Mode 
B-Mode is a two-dimensional image of the amplitude of the echo 
signal. It is used for location and measurement of anatomical 
structures and for spatial orientation during operation of other 
modes. In B mode, a two-dimensional cross-section of a three-
dimensional soft tissue structure such as the heart is displayed in real 
time. 
Ultrasound echoes of different intensities are mapped to different 
gray scale or color values in the display. The outline of the 2D (B-
Mode) (B-Mode) cross-section is a sector, depending on the particular 
transducer used. B-mode can be used in combination with any other 
mode. 
Harmonic Imaging 
Tissue Harmonic Imaging, acoustic aberrations due to tissue, are 
minimized by receiving and processing the second harmonic signal 
that is generated within the insonified tissue. Coded Harmonics 
enhances near field resolution for improved small parts imaging as 
well as far field penetration. It diminishes low frequency amplitude 
noise and improves imaging technically difficult patients. 
It may be especially beneficial when imaging isoechoic lesions in 
shallow-depth anatomy in the breast, liver and hard-to-visualize fetal 
anatomy. Coded Harmonics may improve the B-Mode (2D (B-Mode)) 
image quality without introducing a contrast agent.

M-Mode 
In M-mode, soft tissue structure is shown as a scrolling display, with 
depth on the Y-axis and time on the X-axis. It is mostly used for 
cardiac measurements. M-mode is also known as T-M mode or Time-
Motion mode. Ultrasound echoes of different intensities are mapped 
to different gray scale values in the display. M-mode displays time 
motion information derived from a stationary beam. M-mode is 
normally used in conjunction with a 2D (B-Mode) (B-Mode) image for 
spatial reference. 
Color Flow Doppler Mode 
Color Doppler is used to detect motion presented as a two-
dimensional display. There are three applications of this technique: 
 Color Flow Mode - used to visualize blood flow velocity and 
direction. 
 Power Doppler (Angio) - used to visualize the spatial distribution 
of blood. 
 Tissue Velocity Imaging - The Tissue Color Doppler Imaging is 
used for color encoded evaluation of heart movements. Tissue 
Velocity Imaging images provide information about tissue motion 
direction and velocity. 
Blood flow is displayed as a real-time two-dimensional cross-sectional 
image. The 2D (B-Mode) (B-Mode) cross-section is presented as a full 
color display, with various colors being used to represent blood flow 
(velocity, variance, power and/or direction). 
To provide spatial orientation, the full color blood flow crosssection is 
overlaid on top of the gray scale cross-section of soft tissue structure 
(2D (B-Mode) (B-Mode) echo). Blood velocity is the primary 
parameter used to determine the display colors, but power and 
variance may also be used. 
A high pass filter is used to remove the signals from stationary or 
slowly moving structures. Tissue motion is discriminated from blood 
flow by assuming that blood is moving faster than the surrounding 
tissue. Color flow can be used with 2D (B-Mode) (B-Mode) and 
Spectral Doppler modes.

Power Doppler 
Power Doppler is the same as Color Doppler except that it uses the 
amplitude of the signal to detect movement. The power in the 
remaining signal after wall filtering is then averaged over time to 
present a steady state image of blood flow distribution. It is 
independent of velocity and direction of flow, so there is no signal 
aliasing. It is independent of angle allowing the detection of smaller 
velocities than Color Doppler, making it easier to detect indistinct 
ischemic areas as well as evaluate tiny low-flow vessels. Power 
Doppler can be used in combination with 2D (B-Mode) (B-Mode) and 
Spectral Doppler modes as well as with 4D mode. 
Pulsed (PW) Doppler 
PW Doppler processing is one of two spectral Doppler modes, the 
other being CW Doppler. In spectral Doppler, blood flow is presented 
as a scrolling display, with flow velocity on the Y-axis and time on the 
X-axis. The presence of spectral broadening indicates turbulent flow, 
while the absence of spectral broadening indicates laminar flow. PW 
Doppler provides real time spectral analysis of pulsed Doppler signals.  
PW Doppler can be used alone but is normally used in conjunction 
with a 2D (B-Mode) (B-Mode) image with an M-line and sample 
volume marker superimposed on the 2-D image indicating the 
position of the Doppler sample volume. The sample volume size and 
location are specified by the operator. Sample volume can be overlaid 
by a flow direction cursor which is aligned, by the operator, with the 
direction of flow in the vessel, thus determining the Doppler angle. 
This allows the spectral display to be calibrated in flow velocity 
(m/sec.) as well as frequency (Hz). PW PW Doppler can be used in 
combination with 2D (B-Mode) (B-Mode) and Color Flow modes. 
Continuous Wave (CW) Doppler 
Continuous Wave Doppler systems use two crystals, one to send and 
one to receive the echoes. The transmitter inputs a continuous 
sinusoidal wave. The receiver detects the shift. An audible sound is 
created and recorded by either an analog recorder or spectral 
analyzer. Spectral analysis separates the signal into individual 
components and assigns a relative importance.

The benefits of CW Doppler include high sensitivity to low velocities 
and detection of high velocities without aliasing. CW Doppler cannot 
distinguish between the sending and receiving signals or extraneous 
echoes, nor does CW Doppler produce a precise image like Pulsed 
Wave Doppler. 
Other Modes 
4D: The E9 Ultrasound System can be used to acquire multiple, 
sequential 2D (B-Mode) (BMode) images which can be combined to 
reconstruct a three dimensional image. 4D images are useful in 
visualizing three-dimensional structures, and in understanding the 
spatial or temporal relationships between the images in the 2D (B-
Mode) (B-Mode) sequence. The 4D image is presented using standard 
techniques, such as surface or volume rendering.

Module 4 Network Configuration 
The following sections provide some basic biomedical networking 
background information along with information and procedures 
specific to the GE LogiqE9/VividE9 ultrasound systems.  
DICOM 
The Digital Imaging and Communications in Medicine (DICOM) is a 
standard that specifies a consistent file structure for biomedical 
images and important associated information that must remain 
associated with the images such as patient name time, date, 
institution etc. The DICOM specification identifies the elements 
required to achieve interoperability between medical imaging 
computer systems. 
DICOM addresses these five general application areas:  
 Network image management 
 Network image interpretation management 
 Network print management 
 Imaging procedure management 
 Off-line storage media management 
Prepare for Network Configuration 
You will need to get the facilities network information from the 
system administrator. You can print out the information needed to 
configure the system using the Network Configuration Worksheet 
appended to the end of this manual.  
GE Dataflows 
GE refers to communication between E9 ultrasound systems and 
other information providers on the network as “dataflows”. A 
dataflow is a set of configured settings. For the Vivid systems you can

select a pre-configured dataflow to automatically customize the unit 
to work according to the settings associated with this dataflow. For 
the Logiq systems the dataflows must be configured during system 
set up.
