Measure the dimensions of the 4 mm cystic target to check the image geometry.

Use the 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.

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

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.
