Multi-Leaf Collimator
There are 2 kinds of multi-leaf collimator which have the same features and controls. Their very limited
difference is the color of interface and light source (Figure 8-13 and Table 8-8).
The multi-leaf collimator allows you to adjust the radiation field size to the anatomy. The collimator can
be used in either the manual or automatic mode. This section describes the controls and basic features
of the collimator.
CAUTION Hot Surface! The housing can be heated if the light localizer is switched on for lon-
ger periods of time. Please do not touch the lamp housing until it has been cooled
down in order to prevent burning.
