RaySafe Xi X-ray Measurement System

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.

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.

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.

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.
