5.2 C-Arm Stereo Modes
Acquire the stereo images in either the Auto C-arm Stereo Mode or the Manual C-arm
Stereo Mode. Make the C-arm Stereo Mode selection at the Acquisition Workstation
(refer to How to Select the C-Arm Stereo Mode for Image Acquisition on page 57).
5.2.1 C-Arm Rotation in the C-Arm Stereo Modes
The mechanics of C-arm rotation for stereotactic image acquisition is different in Auto
and Manual C-arm Stereo Modes.
Note
C-arm vertical movement and rotation are disabled when compression force is applied.
A service engineer can configure the lockout force from 22 Newtons (5 pounds) to 45
Newtons (10 pounds).
In Auto C-Arm Stereo Mode
In the Auto C-arm Stereo Mode, the Target Guidance screen does not show the C-arm
Stereo Mode button. In the Auto C-arm Stereo mode, the system automatically lets the
C-arm 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° angle, acquires the image, rotates to the opposite 15° angle and acquires that
image.
Note
The option to position the Tube Arm for the first stereo image is in the System Status
menu (refer to How to Select the C-Arm Stereo Mode for Image Acquisition on page 57). The
Tube Arm automatically rotates to the selected 15° angle. This option operates in both
C-arm Stereo modes.
