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.

Specifications
The device features a sensor array with 41 solid-state sensors and an LCD display for readouts. It has a segment resolution of 0.25 cm (0.1 in) and operates automatically when exposed to X-rays, with an auto power-off feature after 1 minute of inactivity. The battery life is estimated at 6-8 years based on 2000 exposures per year. The operating temperature range is 10-40°C (50-104°F), and it can be stored between -20 and +60°C (-4 and +140°F). The device dimensions are 15 x 30 x 145 mm, and it weighs 75 grams.

Procedures
1. Positioning: Place the RaySafe DXR+ within the light field, aligning the center line with the light field edge.
2. Exposure: Expose the device to X-ray or light. Adjust the collimator if the X-ray field is not aligned with the light field.
3. Readout: Check the display for any deviations in the X-ray or light field alignment.

Recommended Generator Settings
For mammography and radiography, the recommended kVp max is 50 for mammography and 70-100 for radiography. The mA should be greater than 100 for mammography and greater than 200 for radiography. The SID should be less than 65 cm for mammography and less than 100 cm for radiography. The exposure time should be greater than 10 ms, with no added tube filtration.

Additional Information
The RaySafe DXR+ is patented in Sweden and the USA. It is designed to improve digital imaging accuracy and efficiency by eliminating the need for traditional screen-film cassettes, which are becoming obsolete with digitalization.
