Displaying the Guidezone (continued)
The Biopsy Guidezone adjusts along with image adjustments,
such as image inversion/rotations, zoom and depth changes.
The needle may vary from the center line or guidezone for
various reasons:
• Needle barrel to needle clearance or strength.
• Bracket manufacturing tolerance.
• Needle deflection due to tissue resistance.
• Needle size chosen. Thinner needles may deflect more.

Failure to match the guidezone displayed to the guide may
cause the needle to track a path outside the zone.
It is extremely important that when using the adjustable angle
biopsy guides, the angle displayed on the screen matches the
angle set on the guide, otherwise the needle will not follow the
displayed guidezone which could result in repeated biopsies or
patient injury.
