Exradin^® W2MR Scintillator System

Name: Exradin® W2MR Scintillator System
SKU: exradin-w2-scintillator-system
Availability: InStock

The W2 fiber is constructed of completely non-ferrous materials so it can be used for radiation dose measurements in an MR-linac or MR-irradiator. A specific configuration of the W2 with longer optical fibers is available for use in these treatment devices. The longer fiber provides flexibility for a variety of measurement configurations while ensuring that the MAX SD can remain outside the 5 Gauss region of the magnetic field.

Exradin® W2MR Scintillator System part of complete solution for: Annual QA Stereotactic

Exradin® W2MR Scintillator System Overview

AAPM/IAEA TRS 483 states the scintillator is the only detector with a kQ of 1.000, making the W2 the ideal SRS detector.
All corrections are built in.
Inherently waterproof.
Water equivalent.
Can be used for both water scanning and point dosimetry.
User replaceable fiber, includes both 1x1 mm and 1x3 mm.
No dose rate, temperature, or energy dependencies.
The W2 system features Čerenkov corrected measurement signals that can be converted to a proportional analog output, which can be read by any electrometer. This allows the W2 system to be connected to a water phantom system for scanning.
