Stopwatch STOP/START

Softkey

■ Press START to start timer from 0:00:00 (hours:minutes:seconds) or from the

last stopped time (if was not reset). Accuracy is within 1 second.

■ Press STOP to stop elapsed (and active phase times, if using phases). Elapsed

time (and phase times) will remain displayed onscreen.

NOTE: See also “Clip/Image Store (Protocol Button - SmartCart only)” on

page 7-12.

Stopwatch RESET/PHASE

Softkey

■ RESET is available only in Stopwatch STOP state:

Returns Stopwatch to 0:00:00 state

Resets/clears all Phase timers, if present

Removes onscreen Stopwatch display

■ PHASE is available only in Stopwatch START state. Four Phase times are

supported. Displays duration of elapsed time as follows:

Phase 1: From start of Stopwatch

Phase 1+n (2,3,4): From prior Phase

NOTE: Cine Elapsed Time (CET): Upon freezing the image, a second elapsed time

will be displayed, the Cine Elapsed Time (CET). CET indicates the elapsed time for

a particular cine frame or strip location. CET does not affect cine operation.

Stopwatch control functionality is not be affected by displaying CET. Stopwatch

control functionality is not affected by cine scroll or cine play operations. CET is

displayed to the right of onscreen elapsed timer display. Two CETs are displayed

when displayed in nonsimultaneous Dual mode.

NOTE: See also “Clip/Image Store (Protocol Button - SmartCart only)” on

page 7-12.

Image Format Softkey

(C4-1 transducer only)

■ Press to change format. See “Virtual Apex Array Format” on page 7-15.

Frame Rate Softkey Reduces the imaging frame rate and allows for increased contrast agent

concentration between imaging frames.

■ Press Frame Rate softkey up/down to select a frame rate that is lower than the

realtime frame rate.

NOTE: The Frame Rate will not be increased above the initial realtime rate.

Power Softkey Controls the Acoustic Output Power; the A Output selection on the Imaging menu

does the same thing. Raising/lowering the Acoustic Output Power affects contrast

agent detection.

■ Press Power softkey up/down to increase/decrease the Contrast Imaging

acoustic output power.

Gain Softkey Controls the Contrast image Gain only while in Dual or Contrast-only imaging

modes:

■ Rotate the Gain softkey to select the desired Contrast image brightness.

NOTE: While in mixed modes, like Color Doppler and Spectral Doppler, rotate

the 2D/B-Mode button to control Contrast Gain.

Compounding On/Off

Softkey

■ Press this softkey to turn Contrast-specific Compounding on/off.
