DESCRIPTION
Multilayer, square field, manual collimation system with a lightweight and compact
design intended for installation on mobile and stationary X-ray equipment. This device
has been designed and manufactured for skeletal investigations and ER applications.
The X-ray field is defined by six pairs of shutters, four of which are lead-lined. The six pairs of
shutters move perpendicularly within the X-ray field. Two pairs of brass shutters are located
near the focus, two are located near the entrance window and two are located near the exit
window of the X-ray beam from the collimator. The latter shutters serve to accurately define the
X-ray field edges.
Shutter movements are manual, controlled by two knobs on the collimator front panel.
