400 SYSTEM
The LOGIQ
400 has a 64 channel beam former 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. 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
400 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.
