To Turn On Respiration Gating
1. Select an imaging mode that supports respiration gating.
2. Tap the Physiology icon.
3. In the Live Monitoring section, ensure that Live Monitoring is on, and that Resp (respiration) is
enabled.
4. In the Respiration column, adjust the range and offset so that the trace line fits these properties:
The peaks and valleys do not extend above or below the window.
o
The peaks are tall enough to be clearly visible.
o
5. Open the Respiration gating section and enable it.
The orange section on the image display is the gate area, and corresponds to the orange section on
the control panel.
6. While watching the respiration signal on the image display as reference, use the respiration gate
controls on the control panel to set the respiration gate to capture a period of time between breaths.
The respiration gate controls can be adjusted as follows:
Drag the colored area in the middle of the bar to move the gate area.
o
Drag the handles on each side of the bar to adjust the start and end points of the gate area.
o
You can also tap the arrows on either side to make small adjustments.
7. Once all settings are complete, tap away from the Physiology panel to close it.
