The new Unfors DXR, Direct X-ray Ruler, represents the latest in today’s technology for alignment of the light and radiation field.

The Unfors DXR is extremely easy to use as it is powered on by simply exposing the meter. Features include auto reset and auto power off..

There is no need to adjust the light field to a square phantom before making an exposure. No time is wasted waiting for films to be developed.

The pocket-sized Unfors DXR operates down to 100 mA at 70 kVp and gives an objective, reproducible and immediate read-out. X-ray/Light field alignment “The Unfors DXR allows for quick checks with little effort” Fully automatic 10 ms exposure time Auto power on Auto power off 6 - 8 years battery life

Quick checks The Unfors DXR sensor array has been specially designed to meet the needs of real-time checks of the light and radiation field alignment on conventional X-ray equipment. The characteristics of the sensors provide an accurate and instantaneous result where adjustment is needed.

1.Position the Unfors DXR Position the "x-ray"-symbol within the light field. Align the red center line with the light field edge.

2. Expose and read out Expose and read any X-ray/light field deviation in the Unfors DXR display.

The light field edge is aligned with the red center line.

The X-ray field is 1.2 cm (0.5 in) inside of the light field. Adjust the collimator.
