Needle Validation Process

Note
All manual jogs in the following procedure are performed from the Biopsy Control
Module Target Screen, not from the Service Screen. (This screen affects the target
numbers.) The Jog is used to move the needle (and target) away from the phantom
tip, which prevents a collision of the needle tip and phantom tip. This method also
conveniently provides intuitive results without having to correct for the Jog
movement.
Verify the System is Correct for a Known Needle
