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.

System Front End Components
This section covers system frontend topics for the GE Voluson E10. 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.
Voluson E10 Front End Processor (FEP)

Module 3 Operating Modes
The following general operating modes are available on Voluson E10 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 three­dimensional 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 (B­Mode) (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.

Page 26
GE Voluson E10 Training Manual
21
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 Time­Motion 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 two­dimensional 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.

Page 27
GE Voluson E10 Training Manual
22
CW Doppler is optional on the Voluson E10 systems.
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.

Page 28
GE Voluson E10 Training Manual
23
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 (B­Mode) (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 Voluson E10 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 its ultrasound systems and other information providers on the network as “dataflows”. A dataflow is a set of configured settings.
Communication between the Voluson E-Series ultrasound system and other information providers on the network takes the form of data

flows. Each dataflow defines the transfer of patient information from either an input source to the system, or from the system to an output source. The following are the most common examples:
The local database is used for patient archiving. Images are
stored to internal hard drive.
The local database is used for patient archiving. Afterwards
images are stored to a DVD/CD or external USB device, etc.
A remote database is used for patient archiving. Images are also
stored to a remote archive.
Search in the DICOM Modality Worklist, the patient found is
copied into local database. The patient information and the examination results are stored to the local database. Images are stored to a DICOM server and to an image network volume on the local hard drive.
Patient information can include demographic data and images, as well as reports and Measurement and Analysis (M&A) data. A dataflow is a set of pre-configured services. Selecting a dataflow automatically customizes the ultrasound system to work according to the services associated with this dataflow.
By utilizing data flows, the Voluson E-Series ultrasound system is automatically configured to optimally meet the needs of the facility, while keeping the user interface unchanged. Once a dataflow is selected, the actual location of the database is entirely transparent to the user.

STORE / STORE3D Screen
Note:
2D JPEG Quality is only active when 2D
Compression is set to
JPEG.
Cine JPEG Quality is only active when Cine
Compression is set to
JPEG.
Volume Compr. Quality is only active when Volume
Compr. is set to lossy.
Use for servers that cannot handle multiple associations, or do not sort the images by Image Number.
If Send sequ. is checked and the Scan Assistant is activated:
The sequentially “send order” of the images (first, second …) is
derived from the check item order as configured in the setup page (first item, second item …).
If more than one image is available on a check item the send
order is defined by the store date (first stored, second stored and so on…).
If more than one checklist is available: order as configured in
the setup page.
If more than one checklist group is available: order as
configured in the setup page.
Images stored without check item: send order: date, after the
checklist items.
If the Scan Assistant is deactivated it causes all data to be sent
to this server sequentially. This means that only one transfer is active to this server at a time. If one transfer fails, all
subsequent transfers are stopped until the failed transfer succeeds or is removed from the queue.

DICOM Station default - Loads the default settings for DICOM
Station. The destination information must be entered manually.
Viewpoint default - Loads the default settings for Viewpoint.
If the volume contains color information, the color part of the volume is compressed with a setting that is 5 points better than the selected setting, e.g. Setting Mid: color compression High, grey compression Mid
If an image / multifram cine is compressed using lossy JPEG compression, a yellow sign (Jxx; xx = compression factor, e.g. JH) is added to the image (but not to secondary capture images).
If a volume is compressed using lossy, a yellow sign (Wxx; xx = compression factor, e.g. W9) is added when reloading the image.
The Modality Performed Procedure Step MPPS allows you to select the Store Server and the SR Server.
Only the images sent to the selected Store Server are added to the image list of the MPPS completed (or discontinued) message.

The directory structure of the full backup data is as follows:
The sub folders have the names fbX where X is a number (e.g., Z:\fullbackup\fb1).
The data resides within a directory structure within these sub folders. It is possible to move the fbX sub folders, even leaving gaps in the numeration sequence.
However, NO change MUST be made to the contents of the fbX folders itself, otherwise the backup data cannot be restored!
If the destination “Other drive“ is selected, the
available drives (e.g., external USB-memory stick) can be chosen from the pull-down menu.
When the backup is saved to an external USB-device, the system has to be informed about the removal of the hardware.
This is why every "Full Backup Save" and "Full Backup Delete" dialog has a Stop USB Devices button.
External USB-Devices
USB sticks should not have any auto install software on it. Always erase any software from the device first by formatting it on a desktop PC prior to using it unless you are absolutely certain that the device is completely blank.

Module 6 General Safety Precautions
This section is not intended to be an all-inclusive safety procedure guide. It is only brief overview of best practices that applies to all health care facilities and types of medical equipment. You should be familiar with the policies and procedures of the facility where you work AND the safety precautions and procedures described in the manufacturer’s documentation for a particular OEM.
Electrical Safety
The system is a Class I medical device with Type BF and Type CF isolated patient-applied parts. Only CF isolated transducers can be used for invasive (internal) exams.
The following are warnings recommended by the manufacturer:
Grounding prevents shock hazards. The chassis is grounded with
a three wire plug and cable which must be plugged into a grounded outlet.
Never connect the system using a power strip or extension cord. The ultrasound system should never be connected to the same
circuit as life-support devices.
All devices that have patient contact: transducers, ECG leads and
pencil probes that are not specifically labeled as defibrillation proof must be removed from contact with the patient before defibrillation.
Non-medical peripherals such as printers should not be used
within 1.5 meters (5ft) of a patient unless the device is powered with an isolated outlet on the back of the system or an isolated transformer that meets medical safety standards; IEC 60601-1.
Wrist straps should not be worn when working on a system when
the power turned on. The +5 Vdc supply is a very-high current supply. Use caution when troubleshooting.

Electromagnetic Interference
Electromagnetic Interference (EMI) between wireless electronic transmitting devices and medical equipment can cause degradation of the ultrasound image. The system is in compliance with existing EMI/EMC requirements. However, the use of this system in proximity of an electromagnetic field can cause degradation of the ultrasound image at times. Review the environment in which the system is being used, to identify possible sources of radiated emissions. Sources of these emissions can be from electrical devices used in the same or adjacent room. Communication devices that transmit or receive RF signals; cellular phones, pagers, radio, TV, or microwave transmission equipment located nearby can cause these emissions. If EMI from an outside source is causing disturbances, you may need to relocate your
system. Electrosurgical units (ESUs), MRI’s and many other medical
devices introduce radio frequency (RF) electromagnetic fields to the environment. Because ultrasound imaging frequencies are in the RF range, ultrasound transducer circuits are also susceptible to RF interference. For example, the noise generated by an ESU in use can
easily impair or eliminate the ultrasound’s ability to capture an image.
Some measures to reduce the chance of EMI interference include:
Three-meter rule – no powered on cell phones, or pagers within
three meters of the system while in operation.
Locate the system away from other imaging equipment such as
MRI’s that produce strong electromagnetic fields.
Electrostatic Discharge ESD Precautions
Electrostatic discharge (ESD), commonly referred to as a static shock, is a naturally occurring phenomenon. Electrical charges naturally build up on individuals and can create static shocks. The human body can build up a charge as high as 25,000 volts, therefore a discharge from a system user or patient to the ultrasound system can cause damage to the system or transducers. Digital ICs are particularly vulnerable. Low humidity is a condition that favors the build-up of electrostatic charge.
The following are the most common causes of ESD:
Moving equipment Moving people
© 2017 Conquest Imaging
Page 56
GE Voluson E10 Training Manual
51
Low humidity (hot and dry conditions) Improper grounding Unshielded cables Poor connections
Use the following precautions in order to reduce ESD:
Wrist straps Antistatic mats Antistatic spray on carpets or linoleum
Before handling a board or you can touch a grounded surface such as the power supply housing to discharge any built-up charge.
Fire Safety
The following general fire safety practices are relevant for all electrical equipment:
If there is any evidence of smoke or fire disconnect system power
immediately.
On electrical or chemical fires use only extingushers that are
specified for this use. Using water or other liquids is very dangerous and can lead to injury.
General Cautions
The following are general cautions that apply to all ultrasound systems:
Batteries must be handled as hazardous waste. Check that the
cases are intact and the terminals are clean. Follow your facilities procedures regarding disposal should they become damaged.

Module 7 Troubleshooting
This module covers common troubleshooting tools and procedures for the Voluson E10 systems.
Normal Power On/Boot Sequence
The following describes the normal power on/boot sequence for the Voluson E10 systems
The system has two power switches:
The Circuit Breaker Switch is located on the back of the system
next to the power cord plug-in. This allows to the system power supply to power up but does not turn on the system itself.
The On/Off button is located on the user control panel at the
front of the system. This switch initates system Bootup.
Connect AC (mains) Power to the Vivid E9/Logiq E9
Before connecting AC Power to the ultrasound unit you should perform the following preliminary checks of the power cord, voltage levels and compliance with electrical safety requirements.
Ensure that the wall outlet is of appropriate type, and that the
Mains Circuit Breaker is turned off.
Verify that the power cable is without any visible scratches or any
sign of damage.

Press once on the ON/OFF button on the Operator Panel to boot the unit. The ON/OFF button turns green when it is pressed.
During a normal boot sequence, you will notice that:
The unit’s ventilation fan starts on full speed, but slows down
after a few seconds.
Power is distributed to the peripherals, Operator Panel (Console),
Monitor, FEP and BEP.
Back end processor is turned ON and begins to load the software. The Start Screen displays on the monitor. A start-up bar indicating the time used for software loading, is
displayed on the monitor.
The software initiates and sets up the front end electronics. The backlight in the keyboard is lit. When the software load is complete the 2D screen is displayed
on the screen, as long as a probe has been connected, or a No Mode screen is displayed, indicating that no probe has been
connected.
Sleep Mode
Sleep Mode is intended to reduce the boot up time (is less than 120 seconds) on portable studies. Sleep mode saves all memory content in the hard drive and shuts down. When booting up, memory content is then restored from the HDD.
