Appendix C: Descriptions of control panel controls

Sensitivity

Adjusts the signal-to-noise ratio so that you can:

 Better identify weak-signal targets in the near field that are difficult to

distinguish because they are very small

 Better identify large targets in the far field that are difficult to distinguish

because the signal is so attenuated at depth.

The higher you set the sensitivity level, the lower the system sets the frame rate.

Push up to increase sensitivity. Pull down to decrease.

Simul

This toggle control sets the system to acquire live data simultaneously in both the

B-Mode scout window as well as the PW Doppler image window.

In the dual window view, use this feature when you want to adjust your sample

volume in the B-Mode scout window while you view the waveform data in the

PW Doppler Mode window.

To use this toggle control:

1. Press to activate the simultaneous state.

A black vertical strip scans across the spectrum from left to right.

2. To eliminate this striping, press the toggle again to freeze the scout window

and return to PW Doppler image data only.

Active during: M-Mode, PW Doppler Mode and PW Tissue Doppler Mode image

acquisition sessions.

Split Screen

During analysis in a Mode window, toggles between full screen and vertical split

screen. In split-screen display, you can acquire data in one of the two screens.

Study Info

In the Study Browser: Opens the Study Info window for the selected study.

In a Mode window: Opens the Study Info window for the displayed image.
