IRECTION
Vivid q N systems have a digital beam forming system (incorporated in the Front End) that can handle
up to 192 element linear probes using multiplexing.
Signals flow from the Probe Connector Panel, to the Front End (FE) Electronics, to the Back End
Processor (BEP), and finally are displayed on the monitor and peripherals.
In addition, the Vivid q N systems enable acquisition of the following signals: ECG, and external ECG.
The ECG module, which supports acquisition of three bipolar ECG channels
(leads I, II, III), is incorporated in the cabinet cage assembly to provide ECG signals to synchronize
cardiac ultrasound image acquisition. Additionally, other analog inputs from devices such as treadmills
are processed.
