Introduction
System Overview
The LOGIQ 500 digital Ultrasound System is a high
performance ultrasound imaging system, intended for general
purpose applications.
The system provides image generation in B-Mode, M-Mode,
Pulsed, CW and Color Flow Doppler and Color M-Mode with all
transducer types. Digital architecture allows maximum flexibility
of all scanning modes and transducer types, throughout the full
spectrum of operating frequencies.
All transducers are precise solid state array devices, allowing
electronically controlled imaging with Phased Array Sector,
Convex, Micro-convex and Steered Linear probes. Use of solid
state digital designs allows a wide variety of scan parameters to
be optimized including focusing, scan control, spatial resolution,
temporal resolution and contrast resolution. The result is
consistent generation of finely detailed anatomical resolution
with excellent dynamic contrast tissue range and penetration.
LOGIQ 500 also features newly integrated specialized
processing for Flow Data acquisition. Doppler information is
displayed with low noise and clean spectral content to optimize
measurements of important flow parameters. Selected probes
can operate in Multifrequency Mode in order to Optimize
Resolution in B-Mode and Sensitivity to flow in Doppler and
Color Flow Modes.
The system display processor is highly versatile to produce the
optimal set of imaging parameters and display formats without
compromising important diagnostic information. Comprehensive
graphical displays allow rapid and easy placement of Doppler
sample volumes. In Color Flow Mode, combined B-Mode and
Color Flow images can be steered independently so that optimal
positioning is available in both modes.
Versatile, yet easy to use, the LOGIQ 500 system combines a
wide variety of state-of-the-art operator features without
complicating operation. The operator can customize all set-up
parameters for a given mode, probe or clinical application.
Operator controls have been placed in a logical clinical format
with both hard controls and menu-driven soft control
components. Three simultaneous probe connections allow
rapid switching electronically between probes without delaying
the examination.
The LOGIQ 500 System provides a total imaging solution for
today’s diverse ultrasound department needs, with investment
security through reliable upgrades, application enhancements,
and complete product support from GE.
The transmission and reception of mechanical high frequency
waves through a transducer associated with a computer that
creates the image in a digital memory, are used for the creation
of medical ultrasound images. The spreading of mechanical
ultrasound waves produces echoes when body changes
density. In the case of human tissue, these echoes are created
when the signal goes from an adipose tissue (fat) region to a
muscular tissue region, among others. The echoes are
returned through the same transducer that converts them back
into electrical signals. These signals are highly amplified,
processed by filters with several frequency and time response
options, and finally scanned and stored in a digital memory.
Once in the memory, the image can be displayed in real-time on
a monitor. Several analog and digital circuits transform the
electrical high frequency signals into a flow of digital signals,
allowing the composition of the image in the memory. All the
signal reception and transmission parameters are controlled by
the main computer. Through the selection of these parameters
by the operator, the system modifies the transmission and
reception features allowing a wide range of uses, from
obstetrics to peripheral vascular examinations. As its design is
based on solid state components, the system is free from
variations over time and requires very little maintenance. All
the transducers are accurate solid state devices, allowing
control of creation of images from convex, micro-convex and
linear transducers. The use of a solid state design allows a
wide range of sweep parameters that can be optimized
resulting in a consistent creation of fine anatomical details with
excellent penetration and dynamic contrast band in the tissue.
The system features a sophisticated design, providing multiple
functions of diagnostic and function setup keys. This makes the
system user-friendly and easy to use.

Training
Ultrasound energy, even at diagnostic levels, is capable of
damaging sensitive tissues if adequate precautions are not
followed. The wrong combination of equipment settings, probe
positioning, and tissue type can result in injury. Please become
thoroughly familiar with equipment controls that affect acoustic
output levels as well as the output display.
Follow the principle of a
(ALARA) when scanning a patient. During each ultrasound
examination, the clinical user is expected to weigh the medical
benefit of the diagnostic information obtained against the risk of
potential harmful effects. Once an optimal image is achieved
the need for increasing acoustic output or prolonging the
exposure cannot be justified.
It is recommended that all users receive proper training in
applications before performing them in a clinical setting. Please
contact the local GE representative for training assistance.
ALARA training is provided by GE Application Specialists.

Brightness and Contrast
Adjusting the monitor’s contrast and brightness is one of the
most important factors for proper image quality. If these
controls are set incorrectly, the Gain, TGC, Dynamic Range and
even Acoustic Output may have to be changed more often than
necessary to compensate.
The proper setup displays a complete gray scale. The lowest
level of black should just disappear into the background and the
highest white should be bright, but not saturated.
To adjust the Brightness and Contast:
1. Select the Set Up Top Menu. From the Set Up
Adjusting the Monitor
Sub-Menus, select Utility. The Utility Menu appears as
shown in Figure 3–14.
4. Access the Brightness/Contrast controls by pushing on
the top center of the control panel door, located under
the display screen. Push Brightness and Contrast
slidepots to the maximum (to the right).
5. Decrease the Brightness by degrees until “B” in the
gray scale bar is not visible.
6. Decrease the Contrast by degrees until “A” in the gray
scale bar is not visible.
7. Push Brightness slidepots to the maximum (to the
right) again.
8. Decrease the Brightness by degrees until “C” in the
gray scale bar is not visible.
9. Press the Utility rocker switch to return to the previous
scan mode.
Generally speaking, do not change the controls once they have
been set. Once set, the display then becomes the reference for
the hard copy device(s).
