Gantry Overview
The main components of the Senographe DS Gantry are shown below:
The Gantry Column must be securely fixed to the floor, using the provided base plate.
•
Column:
This supports the Compression Arm and allows it be moved vertically, it includes two cylinders:
a fixed cylinder and a telescoping cylinder which elevates the Arm.
•
Compression Arm:
The Compression Arm is connected to the Column by a rotating shaft; it can be
rotated through the range of +185 degrees to -165 degrees.
•
Gantry Readout:
The Gantry Readout display normally shows the following infor-
mation (left to right):
Compressed breast thickness in mm.
Angle of rotation.
Compression force in daN.
It may also be used for warning messages and (for Stereotaxy applications) angula-
tion information.
•
Stop Motion buttons:
There are two Stop Motion push-buttons, one on each side of
the Column. Press one of these buttons to immediately stop all Gantry movement. X-ray acquisition
remains possible.
Note:
If the Arm touches an obstacle during downward movement, the movement is stopped.
•
Stop pre-set automatic rotation of the arm:
An automatic rotation movement started by pressing one
of the preset view selection buttons can be stopped at any time, by pressing any of the buttons located
on the arm or one of the footswitches on the floor, or by touching the compression paddle.
