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.

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

When you are done scanning the phantom, empty the water dam or completely
