Dosimeter System Designed for Quality Assurance in Diagnostic X-ray Applications

New dosimeter features an intuitive interface and effortless measurements of X-ray, and is suitable for all conventional imaging procedures involved in diagnostic X-ray applications.

Unfors RaySafe (previously known as Unfors Instruments; Ulm, Sweden), an international developer of measuring instruments for the quality assurance of X-ray equipment, developed the RaySafe X2 Prestige dosimeter, which is particularly effective due to its user-friendliness. No manual menu settings are required, making it extremely easy to take measurements.

The measuring device consists of a base unit and external sensors for radiography, fluoroscopy, computed tomography (CT), and mammography measurements as well as monitor tests. An additional mAs sensor can be incorporated into the base unit. The sensors capture all pertinent parameters with only one measurement, providing users with the data they require about dose, dose rate, total filtration, kVp, HVL, exposure time, pulse, pulse rate, dose/frame, mA, mAs, and the correspondent waveforms on the touchscreen. The stacked sensor technology also prevents the heel effects on the measurements. The touchscreen can display up to twelve parameters at the same time and delivers parameter-specific graphical analyses by simply scrolling through.

In spite of its intuitive operation, the system is very precise, can save up to 10,000 measurements in the base unit and display the relevant waveforms for kV and dose rates. A variety of measurements are therefore made available for reference and comparison purposes. With the accompanying X2 View software, additional applications are available for performing computer analyses. An Excel interface also offers an easy-to-use reporting option. Field service engineers and physicists save precious time with the RaySafe X2 Prestige, and X-ray machine downtime resulting from tests is kept to an absolute minimum.

“With RaySafe X2 Prestige, we have for the first time developed a system that is highly flexible with capacity for growth—both in terms of the quantitative requirements of the user and the qualitative development of sensors and additional services,” explained Mats Alm, vice president equipment at Unfors RaySafe. “We have a clear roadmap for service programs and hardware support that will make the RaySafe X2 Prestige a long-term, forward-looking solution for X-ray room safety.”

The RaySafe X2 Prestige builds on the RaySafe X2 measuring device, which is equipped with only one R/F sensor and was presented in 2012. It is now available in the Prestige version with R/F, MAM, CT, and light sensors.
