Scan the nearest cystic target group. Each target should be round with a clean
black appearance and well defined edges. Bright specular echoes at the top and
bottom of the targets are normal.
Measure the dimensions of the 6 mm cystic target to check the image geometry.
Use calipers to measure from top to bottom and side to side. Repeat with the
other cystic target groups as part of the cyst imaging test.
9.
Decrease image depth to the minimum and examine the dead zone target group.
The dead zone targets can also be used to measure
lateral resolution
in the
extreme near field of the transducer.
Note
: The highest dead zone pin you can see should be the point of
reference for all measurements – not the scanning surface.

When you are done scanning the phantom, empty the water dam or completely
clean off the coupling gel with a soft cloth or paper towel. Replace the cover and
secure by lifting the handle to protect the phantom.
