5.5 Lesion Targeting with Tomosynthesis Guidance
Lesion targeting for tomosynthesis guided procedures requires system licenses for
tomosynthesis and biopsy.
Note
Make sure that the biopsy device is out of the imaging area.
Note
The overall targeting accuracy is equal to the combined targeting accuracy of the Biopsy
Guidance Module and the biopsy device. When using the biopsy device, the maximum
deviation from the target coordinate will not be more than 2 mm from either side.
1. Acquire the tomosynthesis target (scout) image.
• If your system is set to Auto Accept, the tomosynthesis target (scout) cine runs
briefly and then the system automatically accepts the image.
• If Auto Accept is not set, the cine stops after two passes through the slice deck
(or if the Accept button is pressed before the second cine run finishes).
2. Use the scroll wheel to scroll through the slices of the tomosynthesis target (scout) to
find the best view of the lesion.
3. Click on the lesion.
• A dash appears in the Slice Indicator beside the selected slice.
• The X, Y, and Z values for the target are established automatically at the area of
the click.
4. Select the Create Target button to save the target. The active target set automatically
transmits to the Biopsy Control Module.
5. Repeat steps 2 through 4 to create multiple targets (a maximum of six).
Note
The target that shows on the Target Guidance screen of the Biopsy Control Module is the
last target created. The target or target set that shows on the Select Target screen is the
last target or target set sent to the Biopsy Control Module.
