Chapter 18: Setting up to acquire physiological data

The left panel displays the physiological display setting sections.

3. In the Physiological Range section, adjust the Respiration slider so that the

trace line is a) short enough that the peaks and valleys do not extend above or

below the window and b) tall enough that you can clearly define those peaks

and valleys.

4. In the Respiration Gating section:

a. Select the Respiration Gating check box to activate the slider controls.

b. Adjust the Delay slider to set the start of the gate period, after the

waveform has returned to the baseline.

c. Adjust the Window slider to set the duration of the data acquisition before

the next breath occurs.

5. Press

Pre Trigger

to create your cine loop.

Because

Pre Trigger

records data for a set period after you press the key, the

system acquires only a portion of data during each cardiac cycle, so it takes longer

to acquire the cine loop.

ECG Trigger section

ECG triggering is a feature you can use to effectively acquire imaging frames at a

specific time during the heart cycle.

ECG triggering suppresses this effect.

Use ECG triggering when you intend to add measurements at a specific time.
