Exradin Detectors

Exradin® W2 Scintillator Measurement without perturbation

The optimal water equivalent detector for small field dosimetry

The Small Field Detector Everyone is Talking About

Water Equivalent. Tiny. And Now Optimized For Scanning.

Significant Clinical Advantages

Unlike other detector types, the water equivalent W2 scintillator does not perturb small field dose distributions when it is placed in the beam, so you can measure small fields with greater accuracy.

High Definition

The W2 system features a fiber with a 1x1mm scintillator, improving measurement resolution for the smallest field characterization measurements.

Multiple Detectors Included

Easily switch out fibers to meet your measurement needs. Use a 1 x 1 mm detector when resolution is the primary need and a 1 x 3 mm detector when higher signal strength is required.

Small Field Scanning

Scintillation signal can be sent from the MAX SD to a water tank scanning electrometer in real time, so the W2 can be used for scanning your small field profiles and depth doses.

Exradin® W2 Scintillator Overview

A brief introduction to our water equivalent detector.

I found the W2 scintillator to be an extremely useful tool for commissioning and routine QA of our MRIdian® system. I would recommend this detector to anyone considering it for MR-linac.
