RaySafe DXR+

Product catalog summary

Introduction
The RaySafe DXR+ is a compact tool designed for aligning X-ray and light fields, ensuring compliance with international regulations that recommend alignment within 2% of the Source-to-Image Distance (SID) or ±5 mm at the chest wall for mammography. It provides objective, reproducible, and immediate read-outs down to 30 kVp, making it suitable for both radiographic and mammographic equipment.

RaySafe DXR+ The RaySafe DXR+, a Direct X-ray Ruler, represents the latest in today’s technology for alignment of the light and radiation field. (Traditionally screenfilm cassettes have been used for X-ray and light field alignment measurements. The digitalization of X-ray imaging makes this method obsolete as cassettes and film processors are often unavailable.) It is the ideal solution for performing most accurate measurements for radiography and mammography. Actual size Quick checks The RaySafe DXR+ is an easy-to-use instrument and the ideal solution for improving digital imaging in the radiographic...
