Positioning
1. Place the monobloc–collimator group (A) on the
interested patient part. The monobloc-collimator group
can rotate of +102° and -49° in respect of its axis (B)
and around the arm axis of ±180° (C),
2. Switch the collimator lamp ON.
3. Collimate the radiation beam to the image receptor
dimension or of the examination interest part.
4. Measure the focal distance.
On the front panel of the collimator there are two knobs
(A) to adjust the beam amplitude (width and length),
the push-button to switch ON the collimator lamp (B)
and the tape measure (C) to measure with accuracy the
focus-film distance (DFF).
If necessary, rotate the collimator.
The collimator can rotate around its axis of ±120°.
To rotate it is enough to grip it with both hands and
rotate in the wished direction.
To the min. inherent filtration of the collimator it is possible to add an additional filtration obtained
through a disk moved manually.
On the disk, in addition of a hole for the passage of the x-ray beam without additional filtration
there are the following three filters:
“-“ 1mm Al + 0.1mm CU
”- -“ 1mm Al + 0.2mm CU
“- - - “ 2mm Al
The switching-ON of a yellow LED placed on the front panel of the collimator indicates the
insertion of the additional filtration.
