9 Physiological Unit Signal
Operator’s Manual 9 - 3
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 (Take single trigger as an example):
1. Select exam mode.
2. Select [Trig Mode] on the touch screen to enable the trigger.
3. Set the delay time.
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.
9.2 Respiratory Wave
Perform the following procedure:
1. Connect the ECG lead and position the ECG electrodes.
2. Tap [Physio] or press the user-defined key for “Physio” to enter Physio screen.
3. Switch the imaging modes and display formats, adjusting the parameters to get an optimized
image.
4. Parameter adjusting:
a. Tap [RESP] on the touch screen.
b. Adjust [Speed], [RESP Gain], [Position] and [Invert].
5. Exit Respiratory display mode, and remove ECG electrodes from the patient.
6. Tap [Physio] or press the user-defined key for “Physio” to exit physio mode.
9.3 ECG Review
9.3.1 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.
9.3.2 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.
9.4 Parameter Description
The physio parameters are described as follows:
