3.2.1 Automatic collimator

1. Select Automatic or Manual mode of the collimator.
Note!
If there is no new examination and the System is in a Manual mode, the collimator
ignores the instructions of sent collimator area from the Imaging system. This can be use-
ful if the collimator area is intended to be kept for the next examination.

When Automatic mode is selected the predefined values of the collimator light / x-ray field
size and the filter selection will be set automatically when the anatomical protocol is selected.
Both the light / x-ray field size and the filter can be changed when needed. In automatic mode
the maximum light / x-ray field size is restricted to the maximum active area of the imaging
unit.
When manual mode is selected the size of the collimator light / x-ray field size can be ad-
justed outside of the maximum active area of the imaging unit. When a new anatomical pro-
tocol is selected (for the same patient) the collimator light / x-ray field size or the filtration is
not changed even if size and filtration is defined different in the protocol.
