Automatic format collimation in radiography

Bucky mode

In the Bucky mode, the rectangular diaphragms move to the format of the insert-
ed cassette or to the selected segmentation format. The light localizer is
switched on automatically on selection. The radiation field can then be collimated
smaller as desired. The collimation is retained during the exposure.
Bucky mode is active: LED lights up

Semiautomatic mode

In the semiautomatic mode, the rectangular diaphragms are limited automatically
to the cassette or segmentation format. It is possible to collimate arbitrarily within
the cassette or segmentation format. The collimation is retained during the expo-
sure.
Semiautomatic mode is active: no LED lights up.

Fully automatic mode

In the fully automatic mode, the rectangular diaphragms are limited automatically
to the cassette or segmentation format. It is possible to collimate arbitrarily within
the cassette or segmentation format.
If the rectangular diaphragms are opened less than the cassette or segmentation
format, then they are opened up to the selected cassette or segmentation format
during the preparation.
Automatic format collimation can also be selected separately for height and width
diaphragms. The diaphragms not selected then behave in the same way as with
semiautomatic mode.
Fully automatic mode width and height is active: both LEDs light up.
Fully automatic mode width is active: right LED lights up; left LED is dark..
Fully automatic mode height is active: right LED is dark; left LED lights up..
