•
Maximum compression force
The maximum compression force is 20 daN for motorized compression or 30 daN for manual com-
pression.
•
Arm movement control buttons
Two sets of five buttons are provided, one on each side of the Arm.
They are used in exactly the same way as the corresponding buttons on the sides of the tube head,
described in section
1-1 X-ray Tube Head on page 24
.
•
Arm rotation
The Arm can be rotated b185° and -165°.
•
Interchangeable paddle
The type of paddle inserted in the paddle holder is recognized by the system and displayed on the
Gantry readout. Only paddles designed and validated for use with the Senographe DS system should
be used; the characteristics of these paddles are known by the system and are taken into account,
together with the known characteristics of breast tissue, when calculating parameters such as com-
pression force and breast thickness.
! Notice:
When a paddle is used to apply compression to a rigid phantom (e.g., plexiglass), the thickness
indicated on the Gantry readout is not correct, because of the different characteristics of the ma-
terial as compared to breast tissue.
