Image Quality Verification Test/Livescan

• Products with replaced subassemblies, or products that have been otherwise disassembled, must
undergo an Image Quality Verification Test/Livescan.
• The Image Quality Verification Test/Livescan should be performed after successfully completing all
applicable performance tests listed prior in this chapter.
• The test is completed before returning the system to service.
• A certified sonographer must perform the test.
• The Livescan test performed is at the discretion of the Sonographer and will represent their acceptance
of a successful service event.
• Review all saved images and verify that the images are displayed properly.
1 Connect any transducer.
2 Tap the Color button. A Region of Interest (ROI) box is displayed on top of the

again to return to live imaging.
7 Tap the 2D button to return to 2D imaging.
1 Attach the rC60xi transducer and acquire an image.
2 Set the depth to maximum and note the depth at which echo information is lost.
3 Tap the THI button on the screen controls so it displays THI in the mode area. Tissue
Harmonic Imaging in now active.
4 Observe a decrease in dot size and a significant loss in penetration due to the higher
frequency. Image resolution increases.
5 Tap the Freeze button and then save the image. Tap the Freeze button again to return
to live imaging.
6 Tap the THI button again to turn off Tissue Harmonic Imaging.
