Ion Chambers

razor-chamber

Razor™ Chamber

The Razor Chamber is a compact chamber for measurements of small fields and of ranges with high dose gradients, e.g. stereotactic fields. It is suitable for Relative Dosimetry of photon and electron fields in radiotherapy.

air chamber

Air Ionization Chambers

Designed for measurements with high reproducibility in air, in solid or in water phantoms. They are suitable for relative dosimetry of photon, electron and proton fields in radiotherapy.



farmer chamber

Farmer Type Chambers

Designed for measurements with high reproducibility in air, in solid or in water phantoms. They are suitable for absolute dosimetry of photon, electron and proton beams in radiotherapy.




plane parallel chamber

Plane Parallel Chambers

Designed for measurements with high reproducibility in air, in solid or in water phantoms. They are suitable for absolute dosimetry of photon, electron and proton beams in radiotherapy.



diode detector

Diode Detectors

The diode detectors from IBA Dosimetry are an excellent choice in relative field analysis as well as output factor measurements. They are based on the 3rd generation of pSi semiconductors. The high doped p-type silicon detector chips, specifically designed for radiation therapy applications, have since their introduction in 1992 been the natural choice for measurements where high spatial resolution is required. The accuracy and lifetime of the diode detectors is unsurpassed in the field of radiation therapy today.
