System Overview
Overview
The GE Medical Systems LOGIQ α100 portable
ultrasound scanner is a system designed for OB/GYN,
Abdomen, Urology, Cardiology and Small part scans
using the convex, linear and micro convex probes. The
system provides image generation in B-Mode, M-Mode,
A-Mode(India only), Dual B-Mode and B/M-Mode. High
quality images can be obtained by the proper selection of
scan control parameters. The diagnostic capability is
further enhanced by the different measurement and
calculation packages available in the system.
All probes are precise solid state array devices, allowing
electronically controlled imaging with Convex,
Micro-convex and Linear probes. Use of solid state
digital designs allows a wide variety of scan parameters
to be optimized resulting in consistent generation of
finely detailed anatomical resolution with excellent
dynamic contrast tissue range and penetration.
The System has a sophisticated console design featuring
multiple diagnostic functions and preset function keys.
This makes the system user friendly and easy to use.

Preparing the System for Use
.
Only qualified physicians or sonographers should
perform ultrasound scanning on human subjects for
medical diagnostic reasons. Request training, if needed.
Perform regular preventive maintenance. It is
recommended that service is performed by the
manufacturer or authorized service representatives only.
Never place liquids on the unit to avoid dripping into the
control panel or the unit.
Ensure that unauthorized personnel do not tamper with
the unit.

Use only approved probes. Probes can be connected or
disconnected from the system at any time regardless of
whether the system is powered ON or OFF.
Connecting a probe
1. Carefully unwrap the probe cord.
2. Do not allow the probe head to hang free. Impact
to the probe head could result in irreparable
damage.
3. Ensure probe ‘connector lock’ lever points
towards the 12 o’clock position. (See
Illustration 7.)
4. Align the connector with the probe port and
carefully push into place.
5. Turn the ‘connector lock’ to the 3 o,clock position
to secure the probe connector.

Adjustment of Monitor Contrast and Brightness
Adjustment of monitor CONTRAST and BRIGHTNESS is
one of the most important factors for proper image
quality and it should be adjusted according to the lighting
in the room. If these controls are set incorrectly, the Gain
and Dynamic Range may have to be changed more often
than necessary to give the required image quality.
1. Turn the
CONTRAST

positioned on the inclined face of the front panel,
clockwise or counterclockwise to get a sharp
image and a complete range of gray shades. The

9. When using the Two Probe Port Option do not
carry the system with the probes connected to the
Two Probe Port. This will avoid damage to the
probe connectors. Always carry the equipment
with the Two Probe Port facing away from your
body.
Do not apply any pressure on the system. Make sure the
handle is free from any oil, gel or any slippery substance
which may cause the system to drop.

Clinical Diagnosis
Patient ID/Name should be entered accurately. Make
sure correct patient ID is provided on all recorded data

an incorrect diagnosis.
Equipment malfunction or incorrect settings can result in
measurement errors or failure to detect details within the
image. The equipment user must become thoroughly
familiar with the equipment operation in order to optimize
its performance and recognize possible malfunctions.
Applications training is available through your local GE
representative. Added confidence in your equipment
operation can be gained by establishing a quality
assurance program.
Only qualified physicians and sonographers should
perform Ultrasound scanning on human subjects for
medical diagnostic reasons. Exposure levels to be kept
to minimum and to be consistent with recommended

diagnosis can be made. The user is encouraged to

Hazard
Damaged probes or improper use and manipulation of
intracavitary probes can result in injury or increased risk
of infection. Handle the probes with care. They may be
damaged if dropped or mishandled. A damaged probe
has to be scrapped. It cannot be repaired or reused. Do
not allow the lens to come into contact with a sharp
object or to be knocked against an object. Be sure to put
the transducers in the side slot before transporting.
A damaged probe may cause an electrically hazardous
condition if conductive solutions come in contact with
internal live parts. Do not use any probe with damaged
lens to scan a patient. Inspect probes often for cracks or
openings which could allow liquid entry.
To avoid electrical shock, use only the supplied power
cords and connect them only to properly grounded (three
hole) wall outlets. Do not use a 2 prong–adaptor.
The system should be operated within the voltage limits
defined in
Do not place liquids on or above the console. If the
liquid spills, it may come in contact with live parts and
increase the risk of shock.

Patient Safety
Acoustic
Output
Hazard
Although there have been no confirmed adverse effects
produced by diagnostic levels of ultrasound, avoid
unnecessary exposure of ultrasound energy to the
human body. Wrong scan settings, probe positioning and
tissue type can result in injury. Use the minimum
necessary output to get the best diagnostic image or
measurement during an examination. Begin an exam
with a probe that provides optimum focal depth and
penetration.
Follow the principle of “as low as reasonably achievable”
(ALARA) when scanning patients. Once an optimal
image is achieved, the need for prolonging the exposure
cannot be justified.
The principle of ALARA, which stands for “As Low As
Reasonably Achievable”, is to keep the radiation
exposure at the minimum level necessary to obtain the
diagnostic information. This principle is widely practiced
in medical X–ray protection where exposure at any level
is potentially harmful. Historically, ALARA was initiated as
a cautious approach for dealing with uncertain hazards
but has since become the principle method for reducing
the risk of injury from hazards that do not have safe
minimum thresholds.
While no minimum thresholds for harmful bio-effects
have been established with the use of diagnostic
ultrasound, the principle of ALARA can be readily
implemented on equipment incorporating an output
display. As the operator adjusts the equipment to
optimize the image quality, the display interactively
updates to indicate the effect on output.
