3.2 Stereo Biopsy Modes
Acquire the stereo images in either the Auto Biopsy Mode or the Manual Biopsy Mode.
Make the Biopsy Mode selection at the Acquisition Workstation (refer to How to Select the
Biopsy Mode for Image Acquisition on page 30).
3.2.1 C-Arm Rotation in the Biopsy Modes
The action of C ‐ arm rotation for stereotactic image acquisition is different in Auto and
Manual Biopsy Modes.
Note
All C ‐ Arm movement is disabled when a compression force
of 22 Newtons (5 pounds) or greater is applied.
In Auto Biopsy Mode
In the Auto Biopsy Mode, the Target Guidance screen does not display the C ‐ Arm Stereo
Mode button. In the Auto Biopsy mode, the system automatically allows the C ‐ arm to
move separately from the Tube Arm to acquire the stereo images. When the x ‐ ray button
is pressed to start stereo image acquisition, the Tube Arm automatically moves to the first
15° position, acquires the image, rotates to the opposite 15° position and acquires that
image.
Note The System Status menu (refer to How to Select the Biopsy
Mode for Image Acquisition on page 30 ) provides the option to
position the Tube Arm for the first stereo image. When you
select either of the 15 degree positions, the Tube Arm
automatically rotates to the selected position. This option
operates in both biopsy modes.
