Gating Interface The source of the gating signal may arise from the ECG or SpO
2
. The
gating signal from either of these sources may be delivered to the
scanner in two user-selectable forms—waveform or pulse.
• Waveform output: one of the following: 1mV ECG waveform or
a plethysmogram (SpO
2
) waveform.
• Pulse output: 1mV pulse amplitude and 50 msec pulse width,
synchronous with the r-wave or corresponding peak of the
plethysmogram (SpO
2
) waveform.
The delay time from detection of the ECG signal at the patient to the
input of the MR scanner is less than or equal to 5 milliseconds.
One of two icons appears in the upper left corner of the heart rate
numerical display box. These icons represent the gating signal
output—either waveform or pulse. The icon is the same color as the
ECG waveform color. See Step 6 below.
The gating function is user-selectable: OFF, ECG Waveform, ECG
Pulse, SpO
2
Waveform, or SpO
2
Pulse. The default is OFF.
1. Connect the cable appropriate for the scanner to the GATING
connection on the Veris patient monitor.
NOTE: The gating cable must be IEC 950 or IEC 60950
compliant.
