3.2 Automatic Collimator Control
The collimator is used to adjust the size of the x-ray field to cover the area of interest of the
patient by adjusting the collimator light field size. The collimator light field size / x-ray field
size and the collimator filtration can be predefined in the anatomical protocols and is then set
automatically when the protocol is selected. The size of the light / x-ray field and the filtration
can then be adjusted when needed to adapt to the patient.
The collimator can be operated from the collimator interface at the Overhead tube crane,
from the hand control at the wall stand or from the control handle at the table (option).
The following figure shows the functions of the automatic collimator.
