Correcting Needle Guide Positioning for Biopsies
When you receive needle guides, they are already configured and tested for angle and
depth. The angle is the number of degrees between the X-axis and the Y-axis (the needle
axis). The depth, shown in millimeters, is the point at which the biopsy needle and guide
lines intersect the vertical center line of the 2D image.
You can make marginal changes to the upper and lower limits for angle and depth on the
Needle Guide Error Correction dialog box. Your changes to these settings are visible in the
needle guidelines, and are saved by the system and used for all biopsies until you change
them again.
You can enter a value within these ranges:
• Angle: –2° to 2°
• Depth: –1 mm to 1 mm
To change the needle guide error correction values for any transducer except the biplanar
transducer, complete these steps:
