RaySafe Xi Prestige X-ray Measurement System

Meet the family!

The RaySafe Xi is a complete system for multiparameter measurements on all X-ray modalities. It simultaneously measures everything from kVp and dose to HVL and waveforms. It is preferred by leading experts from all over the world. Invest just a few seconds of your life in RaySafe Xi, and it may completely change it. At least in the way you measure on X-ray equipment. – a wide range of detectors for different applications.

“I have used Unfors RaySafe’s test equipment for the last 10 years. The products on offer from this manufacturer allow the full diagnostic testing of all radiation producing equipment and the sensitivity for evaluation of premises used in Radiology. Jeff Gibson and his team @ INMED in Australia have provided me with exceptional service and back up. When equipment is away on calibration INMED has been able to provide loan units on all the equipment he sells. Being a “one man show this has been invaluable. Jeff has kept me up to date with the various modality changes and provided equipment for evaluation to assist me to meet the demands of this ever changing industry. I purchased a few new “toys (as my wife likes to call them) from INMED recently: a vacuum holder and a translucent probe. These two items have fitted in with my “kit very nicely (actually I wonder how I ever got along without them). My kit is able to assess all radiation producing apparatus at the highest standard and every permutation of these devices. This is the best equipment on offer.

Detectors:

The base unit is the heart of the RaySafe Xi system. Simply connect any of the detectors and you’ll be up and running in no time. The three row back-lit alphanumerical display clearly presents all measured parameters. All functions are accessed by pressing one of the two buttons on the RaySafe Xi.

The RaySafe Xi supports both RS-232/USB and the optional Bluetooth data communication protocols. The RaySafe Xi view software provided is used to record measured data, waveforms and test results in Excel™ as well as controlling the instrument using the new bi-directional serial interface.

There are two versions of the RaySafe Xi base unit – one with and one without mAs capabilities. Both are fully compatible and interchangeable with all RaySafe Xi detectors.

RaySafe Xi View Software

RaySafe Xi View is a stand-alone software which displays and stores all exposure data including kV, radiation and mA waveforms measured by the RaySafe Xi. Data is stored in an XML or CSV format for later retrieval, analysis and reports.

Furthermore, RaySafe Xi View enables you to control your RaySafe Xi remotely from a PC and to transfer measured dose data directly into Excel™ for additional reports.

There are two options of connecting your RaySafe Xi using the RaySafe Xi View: With the RS-232 cable to the PC or with an optional Bluetooth module directly to the RaySafe Xi serial port.

Features

The values of the RaySafe Xi

Modular

Whether you start with a base unit and one detector, or a Prestige Kit for all modalities, the RaySafe Xi makes it easy for you to grow your system over time or as your needs change. Additional detectors and options can be added at any time to enhance the capabilities of your system. This makes the RaySafe Xi a smart investment now, and for the future.

Preferred

In 2011, the RaySafe Xi became the most widely-used Diagnostic X-ray quality assurance tool in the world. Leading manufacturers of X-ray equipment around the world have standardized on the RaySafe Xi from their R&D, to their factory to their field service technicians. The majority of diagnostic physicists and government inspectors also use the RaySafe Xi in their daily work. This makes any needed measurement comparison between biomedical engineers, physicists, inspectors and field service engineers simple and consistent.

Simple

A good tool should simplify your life, not complicate it. The RaySafe Xi goes from set up to results in under a minute. With its intuitive user interface and two key operation, it is easy to learn and master. RaySafe Xi view software shows waveforms and easily exports data to Excel for reporting. Because we understand that you want to focus on interpreting the measured data instead of worrying about how to obtain it.

Accurate

The RaySafe Xi solid state technology offers many benefits, including durability, a smaller footprint, and enhanced sensitivity. But did you know that our proprietary solution also provides increased accuracy? All RaySafe Xi detectors use multiple sensors and have our “Active Compensation system. This provides a flat energy dependence, not only for radiography and fluoroscopy but also in the mammography range. It also gives our users the ability to measure multiple parameters all in one instrument including HVL – on the fly.

Durable

QA instrumentation needs to withstand life on the road – and its inevitable bumps. The RaySafe Xi is prepared for the most demanding applications. From its durable case with its custom foam insert to hold detectors and accessories, to the robust design of the base unit and solid state detectors, the RaySafe Xi can easily manage the unavoidable drops and mishaps.

At your service

Keeping your instrument performing and looking like new is easy with our annual service program and extended warranty. Simply send in your instrument annually for calibration and we will extend the full warranty for another year for up to 5 years. Your annual service includes the most comprehensive calibration in the industry, firmware updates, and free replacement of any damaged or unsightly parts in your instrument and in your case. Our service customers benefit from a faster turnaround time and an ISO 17025-certified calibration facility using NIST/PTB calibration standards. Because your reputation and the quality of your service depends on a well-calibrated and maintained instrument.
