2.2.2.1 Initiating Electrode Impedance Check
User Console
The user console allows you to initiate an impedance measurement, if the internal ECG trigger
device is selected and active.
1. Right-click on the ECG waveform in an active patient study.
2. Select
Test Electrode Impedance
.
Gantry Display
The gantry display allows you to initiate an impedance measurement, if the internal ECG trigger
device is selected and active.
1. From the gantry display, select the
ECG Settings
menu.
2. Select
Test Electrode Impedance
.
2.2.2.2 Electrode Impedance Check Results
The system displays the electrode impedance check results on both the user console and the
gantry display. Measurements are displayed with a color indicating whether the measurement is
within the allowed threshold.
•
Green indicates a good electrode connection.
•
Red indicates a poor electrode connection.
2.3 Acquire a scout scan
Use this procedure to acquire a scout scan series for the cardiac protocol.
1. From the scan monitor, open the
Patient Schedule
drawer.
2. Select the patient to be scanned and double left-click or click [Select Patient].
3. Enter the patient's information.
4. Start or connect the IV line to the contrast tubing.
5. Review the contrast effects with the patient.
6. Attach the electrodes to the patient, if you have not already done so.
See
NOTE:
Do not scan until you have an acceptable cardiac waveform and heart rate.
7. Secure both IV tubing and ECG cables. Make sure that the cables do not dangle from the
table.
ECG lead wire movement during the scan can result in a degraded signal.
8. Review breathing instructions with the patient.
9. From the
Protocol Selection
window, select a cardiac protocol and click [Accept].
10. From the
Scan Settings
window, review the current settings and click [Confirm Settings].
