RaySafe Xi

Overview

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 operations, 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.

RaySafe Xi View

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.

Models

Sensors/Detectors

R/F Detector

From the lowest to the highest without corrections.

Whether your application is dose rate measurements on pulsed fluoroscopy or kVp measurements on intra-oral machines, the RaySafe Xi is capable of handling all user scenarios. Only one detector is needed for low dose rate measurements up to high exposures, while Active Compensation ensures high precision regardless of the beam quality. If you need to study the waveforms, the RaySafe Xi offers up to 1200 ms waveform memory at a detector bandwith of 2.5 kHz for both kV and radiation output.

The RaySafe Xi R/F detector is capable of measuring kVp, dose, dose rate, pulse, pulse rate, dose/frame, time, HVL, total filtration and waveforms simultaneously. This is done with minimal user interaction since the instrument has many built-in intelligent solutions, such as automatically detecting and calculating the pulse rate and dose/pulse, or direct HVL measurement for each exposure. The R/F detector is also suitable for intra-oral, cone beam and OPG dental machines as well as kVp and HVL measurements on CT.

MAM Detector

The RaySafe Xi editions offer the following features for mammography measurements:

Algorithms to handle tube ageing effects and variations between different manufacturer’s tube/filter combinations
0.5 kV or 2% precision for all mammo kVp (Mo/Mo, Mo/Rh, W/Rh, W/Al)
PTB approved for all beam qualities (entrance and exit dose)
Direct HVL measurement in one exposure
Solution for Scanning Mammo (W/Al)

Developed in partnership with leading manufacturers

A unique feature of the RaySafe Xi MAM detector is its ability to directly measure the HVL for each exposure without the need for filters and multiple exposures. In addition, the standard RaySafe Xi MAM detector simultaneously measures kVp (Mo/Mo), dose, dose rate, HVL, time and waveforms on common beam qualities (Mo/Mo, Mo/Al, Mo/Rh, Rh/Rh, Rh/Al and W/Rh) used in today’s mammo X-ray machines.

The RaySafe Xi editions offer extended MAM capabilities when adding optional calibrations such as the M-Pro 2.0 option with kVp, dose and HVL measurements on W/Rh, Mo/Rh and dose and direct HVL on W/Ag. M-Pro 2.0 Plus also adds kVp, dose, HVL and time measurements on W/Al as well as combo mode using both W/Rh and W/Al during the same exposure.

Additionally, a detector for Scanning Mammo using W/Al can be added to your RaySafe Xi. RaySafe Xi MAM with M-Pro has been developed with leading manufacturers to accommodate new mammographic beam qualities. It can be used on mammography equipment made by Hologic, Sectra, Planmeca, Giotto, GE, Siemens and others.

CT Detector

CT dose made easy

The RaySafe Xi CT detector is a hybrid ion chamber designed by Unfors RaySafe. The ion chamber and electronics are combined into one unit making it possible to measure both temperature and pressure to actively compensate for this dependency. The temperature is actually measured inside the ion chamber giving very precise compensations both with and without a CT phantom. With no baseline drift, this carbon fiber ion chamber is ready to use within one minute.

Transparent Detector

Virtually transparent to X-rays.

The RaySafe Xi Transparent detector is the perfect complement to the RaySafe Xi R/F detector. The transparent detector enables easy and fast dose and dose rate measurements without disturbing the kVp, mA, or mAs parameters of an ABC or AEC exposure. This allows a simple and accurate setup for measuring entrance skin exposure and entrance skin exposure rate. Unlike the R/F detector, the transparent detector is designed to measure scattered radiation. It also has negligible energy and beam quality dependence over the entire diagnostic energy range.

Survey Detector

Small and precise solution for survey measurements.

The RaySafe Xi Survey detector is a unique design based on solid-state sensors with clear benefits in size, sensitivity and durability. The new RaySafe Xi Survey detector can be used for scatter and leakage measurements in X-ray and nuclear medicine applications. Since the detector is based on solid-state sensor technology, there is virtually no warm-up time and no temperature or pressure dependencies. A response time of as low as 0.5 s and an audible tone proportional to the dose rate makes it very easy to use. The detector has high sensitivity paired with an excellent energy response and is suitable for usage in the energy range of 13 keV to more than 1.25 MeV, thereby delivering precise measurements.

Light Detector

High precision and convenience for testing medical monitors and more.

The RaySafe Xi Light detector is capable of measuring illuminance and contact luminance measurements on CRT and LCD monitors as well as testing view boxes and collimators. Luminance or illuminance measurements are easily selected by either attaching or detaching the optical tube to the detector housing. Data can be stored in the internal memory or exported to the RaySafe Xi View via serial or Bluetooth communication. The RaySafe Xi Light detector has a perfect cosine-corrected response for ambient light and a state-of-the art photopic response. In addition, it fulfils the DIN 5032 Class B specifications for both illuminance and luminance.

mAs Detector

Invasive measurement of tube current.

Simultaneous measurements of radiation parameters and mAs can be obtained with the detector placed in the radiation field and the meter connected to the mAs ports. After each exposure, all parameters will be displayed as well as waveforms for further study. As a stand-alone meter, mA, mAs, time, pulse, pulse rate, mAs/pulse and waveforms will also be displayed after and during each exposure. When using the provided RaySafe Xi view software, individual pulses can be viewed and analyzed from the waveform.

Software

RaySafe Xi View

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.
