Figure 11-9: Biopsy guide zone
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.
1. Biopsy guide zone
• 5 cm between the red marks
• 1 cm between the large yellow marks
• 0.5 cm between two consecutive marks
The first red mark is at 5 cm from the top of the needle
guide.
DANGER
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.
