Pulsed Wave (PW) Doppler Imaging
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
“Setting Up Performance Tests,” on page 69
• 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.
