10 Physiological Unit Signal
Operator’s Manual 10 - 3
• The marks in Dual trigger are in different colors.
• Triggering function is unavailable if the ECG trace is disappeared. Only the live 2D image can
be triggered.
• No delay time or time interval shall be less than the time required to scan a single image.
• If the delay time is longer than a heart cycle, then the heart cycle in the delay time is omitted,
that is to say no trigger is occurred when R waveform is detected in the duration.
Triggering Mode
There are three triggering modes available: Single, Dual, and Timer.
•
Single Trigger: When an R waveform is detected, an image will be triggered after delay time
T1. The time of T1 can be edited in single mode.
• Dual trigger: when an R waveform is detected, two images in two windows will be triggered
respectively after delay time T1 and T2. The time of T1 and T2 can be edited in dual mode.
• Timer Trigger: an image will be triggered after a time interval.The time interval can be edited
in triggering status.
The image triggering operation is described as follows (Take single trigger as an example):
1.
Select exam mode.
2. Tap [Trig Mode] to enable the trigger.
3. Select [Single].
4. Set the delay time (or use the T1 by default).
Real & Trigger
Tap [Real & Trigger] to enable or disable the real trigger function.
After the [Real & Trigger] is enabled, two images are displayed respectively in two windows. One
is triggered by ECG, and the other is non-triggered real time image.
10.1.2 ECG Review
Review Principle
When an image is frozen, the ECG waveform where the image is triggered will be frozen at the
same time. In the Dual triggering mode, the two window images are frozen at the same time. When
images are reviewed with the ECG electrodes connected, the ECG trace is the reference for time.
After the images are frozen, all real time images are in the status of linked review.
Linked Review of ECG Waveforms, M/D Images and 2D Images
If the physio unit signal, time curve and 2D image are frozen at the same time, the replay of them is
displayed at the same time.
10.2 Respiratory Wave
Perform the following procedure:
1.
Connect the ECG lead and position the ECG electrodes.
2. Tap [Physio] or press the user-defined <Physio> key to enter Physio screen.
3. Switch the imaging modes and display formats, adjusting the parameters to get an optimized
image.
4. Parameter adjusting:
