TFG RulerModel 033
Create Permanent alignment Record
Confirmation of alignment between laser lights and the X-ray energy field is a routine QA check. Although there is equipment available, they do not provide a permanent record of the results. The Model 033 TFG Ruler is a low cost, simple to use tool that can provide this permanent record.
The TFG Ruler is a Light Field Alignment Calibrator Tool. The TFG Ruler is designed to work as a stand alone product, or to work in tandem with the Unfors DXR+ Light Field Alignment Tool. When used with the DXR+ ruler, the TFG Ruler can be used for FFDM X-ray field overlap measurements.
The acrylic ruler has radiopaque indices at 1 mm increments making it suitable for mammography applications. The cutout enables the TFG ruler to be compatible with the Unfors DXR+ or alone.
To use, position the zero index at the edge of the light field, expose the film and then visually inspect the visible measurement index on the film and record your results.
