9 Physiological Unit Signal
Operator’s Manual 9 - 3
Triggering Mode
This system supports 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.
The image triggering operation is described as follows:
1. Select exam mode.
2. Tap [Trig Mode] to enable the trigger.
3. Set the delay time T1.
9.2 ECG Review
9.2.1 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.
9.2.2 Linked Review of 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.
9.3 Parameter Description
The physio parameters are described as follows:
