when facing the Gantry. The sketch shows the

Angulation
The operator selects the breast
laterality, Left or Right.
The system senses the presence or
absence of the magnification platform
The system selects a view name according to the
tube angle and the laterality. Default values for the
angles used are given in the table below.
The tube is at –4
5 _ 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 the
magnification platform is present, it also adds the prefix M.
Automatically selected view name: R M SIO
Example:
Operator selected laterality: R.
Magnification platform: Present.
