Laterality
The operator selects the breast laterality,
Left or Right.
Magnification
The system senses the presence or absence of
a magnification stand
-45°
Arm angles are measured from the vertical 0°
position, with positive angles counter-clockwise
when facing the Gantry. The sketch shows the
tube at -45°.
Arm rotation angle
The system selects a view name according to the
arm angle and the laterality. Default values for the
angles used are given in the table below.

to the Left
Tube Head
to the Right
The tube is at -45° and the selected laterality is R, so the inferior side
of the breast is against the receptor. The system therefore selects the
view name
SIO
, and adds the laterality prefix R. Because a magnifi-
cation stand is present, it also adds the prefix M.
