Decrease the image depth and examine the axial resolution target group at 1 cm.

Notice how the images of the lower pin targets may begin to merge. The smallest

distance between two pins that can be clearly resolved with no vertical overlap is

called the scanner's axial resolution.

Pin target are resolved axially if an imaginary horizontal line can be drawn

between the targets without touching either target. The targets on the left are not

resolved. The targets on the right are resolved.

Examine the other axial resolution target groups and compare the resolution at

various depths. Axial resolution may change with depth.

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.
