Operation
Tests 1 Verify that the correct transducer name appears in the upper right corner of the system
display.
2 Verify proper date and time.
3 Verify that the scan plane orientation mark in the image located near the skinline
corresponds to element #1 on the transducer. To test, put your finger on the probe and
run it across the transducer face. Your finger touching the transducer face should
appear at the orientation mark on the display image format.
4 Verify that all of the User Interface and persistent control features are functional. Verify
that all controls operate smoothly over their full range and that the system responds
properly.
5 Verify that as the Gain controls are increased and decreased, there is a corresponding
increase and decrease in echo intensity.
6 Capture a Cineloop buffer. Exercise the Cineloop controls and verify proper operation.
7 Verify the airflow from the fan vents on the rear of the system flow outward.
Test 2D
Performance
and Image
Quality 1 Use a C5-1 transducer in 2D mode.
2 Adjust the position of the C5-1 transducer on the phantom.
3 With the array pointing down and the orientation mark to the operator’s left, element
#1 corresponds with the left side of the array.
4 Use the 2D system controls to obtain a clear image that shows both the horizontal and
vertical rows of pins.
5 Verify that the ultrasound image appears uniform in both the axial and lateral direction,
with no dropouts or intensity variations.
6 Verify that the cystic structure at the focal zone is clearly differentiated from the
surrounding tissue and is echo-free, while solid tissue with numerous echo sources,
appears solid.
7 Press the Freeze button and then save the image. Press the Freeze button to return
to live imaging.
