Biopsy screens
The following illustration shows the biopsy gun graphic. It indicates the ideal
biopsy needle path as a dotted line at an angle to the image. When the needle can
be mounted in more than one position, the Crossover Depth rotary control
selects the angle. The spacing along the needle path is 1 cm for deep depths and
0.5 cm for shallow depths.
A crosshair cursor on the dotted line indicates the target. The trackball controls
the cursor location. In the upper right corner of the screen display, NEEDLE
LENGTH indicates the minimum length of needle required to reach the target.
This is the distance from the top of the needle guide to the target.
NEEDLE LENGTH=8.0 CM
