DESCRIPTION
Square-field, x-ray collimator suitable for installation on stationary x-ray equipment. The
collimator has been designed and manufactured for clinical skeletal and thoracic
investigations.
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 bronze 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.
The square field X-ray beam Limiting Device is designed for installation on fixed or rotating
anode X-ray tubes that, when mounted, conform to EN 60601-1-3 par 29.202.3. ; motorised
controls provide for the stepless adjustment of the X-ray field dimension to the size of the image
receptor or to that of the anatomical area of interest. Adjustment to the area under investigation
is possible by using the two knobs on the front panel
Direct visualisation of the x-ray field is given by a light beam which corresponds to the x-ray
beam, within a tolerance of two percent of the selected FFD (SID) value. The light-field centre
is provided by the intersection of two perpendicular lines silk-screened into the Lexan window
and projected on the light field by the light beam.
To activate the light field, press the area marked with the light symbol on the front ot the device.
The light will switch on for 30 seconds and an electronic timer will switch the lamp OFF
automatically.
Average illumination is not less than 160 LUX; edge contrast ratio is minimum > 4:1. Field size
at the different Focus Film Distance (FFD - SID) settings is shown on the front panel.
