5–1 INTRODUCTION
LOGIQ 500 is a compact ultrasound scanner supporting a wide range of probes. This gives the system added benefits
to meet diverse applications.
5–2 LOGIQ 500 SYSTEM
The LOGIQ 500 has a 64 channel beamformer that digitizes the RF signal. It uses analog and digital delay to focus the
beam. The analog delay is short and fixed. The digital delay is used for long delay and dynamic focus. It offers parallel
receive beam formation which can increase frame rate by a factor of two in time critical applications like Color Flow.
This system also features many advanced image processing controls.
User surveys and the latest technology were used to increase console ease–of–use. Digital circuitry enables more
reliable and precise operation.
System Features
The key design goals of this system are:
• High Image Quality
• Increased User Productivity
• Multiple Clinical Applications
• Planned Upgradeability
• High Mobility
Types of Applications
The system supports many clinical uses. Scan and display parameters may be user selected to default to desired
values for each application. The system presets many parameters to clinically determined, optimal values.
• Radiology
• Cardiology
• OB/GYN, and
• Vascular
See Illustration 5–1, the LOGIQ 500 system can be divided into an analog signal processing section, a digital signal
processing section, and the microprocessor driven system control section, which controls the system based on
operator commands and system status information.
