Product Description
The purpose of the multileaf collimator is to collimate
exactly the radiation beam emerging from the X-ray tube
assembly onto the size of the object to be displayed.
Collimation is manual with the aid of the field light
localizer (except A 01 II and AF 01 II) or motor-driven by
automatic format collimation system.
The current source-image distance (SID) and the size
of the collimated radiation field are displayed on a LCD
display except A 01 II, AF 01 II.
A laser line localizer is available for centering the bucky
except for type A 01 II, AF 01 II.
For optimizing the image and radiation quality three
different Cu-filter can be selected.
Features
◾ Lamellae close to the source to shield off extrafocal
radiation
◾ Additional prefilters integrated in the collimator for
manual (AL 01 II eL) or motorized operation (AL 02 II eL,
A 01 II, AF 01 II, AFL 01 II eL)
◾ Bucky light generated by laser results in a sharp
light line for all source-image distances (not A 01 II and
AF 01 II)
◾ Display of field sizes optionally in cm (default) or inch
where available
◾ Rotation by ± 45° with a stop in 0° position by swiveling
flange (not A 01 II and AF 01 II)
◾ Tape measure integrated in a user friendly way in the
collimator (not A 01 II and AF 01 II)
◾ Two foam protected accessory rails facilitate attachment
of additional devices and further filters (not A 01
II and AF 01 II)
