IBA RAZOR™ Diode Detector - BNC

High Performance Diode Detector for Small Field Dosimetry


The RAZOR™ Detector is a diode detector for measurements of small fields and of ranges with high dose gradients, e. g. stereotactic fields.

 

Suitable for Relative Dosimetry of photon and electron fields in radiotherapy
• For SRS / SBRT photon and electron beams
• Commission Accuracy & Efficiency

 

The unshielded RAZOR™ Diode detector is intended for relative Dosimetry of photon and electron beams in radiotherapy. The detector is designed for depth dose and profile measurements “in air” (i.e. inside a solid phantom) and in a water phantom, and for output factor measurements in small to medium sized photon beams.

The RAZOR™ detector is based on a p-type silicon diode chip, specifically designed for radiation therapy applications, and for the relative dosimetry of electron and stereotactic photon fields.

Performances verified in the range of photon beam qualities 60Co-15MV and 6 - 15MeV electron energies.
