70 C1.9 PLUS Ultrasound System Service Manual
8.5.4 Tissue Harmonic Imaging
1.
Attach the C60 transducer and acquire an image.
2. Set the depth to maximum and note the depth at which echo information is lost.
3.
Press the Menu key.
4. Press the T
H
key on the on-screen menu so it displays T
H
(on). Tissue Harmonic
Imaging in now active.
5. Observe a decrease in dot size and a significant loss in penetration due to the
higher frequency. Image resolution increases.
6. Press the T
H
key again to turn off Tissue Harmonic Imaging.
8.5.5 Pulsed Wave (PW) Doppler Imaging
1.
Attach the C60 transducer.
2. Press the 7 key for the Doppler sample gate.
3.
Press the 7 key again for the Doppler spectral trace.
4. Place a large drop of ultrasound gel on the transducer lens.
5.
Gently tap the top of the gel and observe a reflection on the spectral trace and the
sound from the speakers.
6.
Press the 0 key to return to 2D imaging.
8.5.6 ECG Monitoring
1. Connect an ECG Cable to the I/O connector located on the left side of the
system.
2. Connect an ECG simulator set for 60 BPM, Normal Sinus Rhythm.
3. Set the ECG amplitude to 0.5 mV and verify the trace stabilizes and shows the
appropriate waveform.
4. Set the ECG amplitude to 2.0 mV and verify the trace stabilizes and shows the
appropriate waveform.
5. Save an ECG image.
