Detectors for Relative and Absolute Dosimetry
IBA Dosimetry offers a full range of ionization chambers and pSi semiconductor detectors for various 2D and 3D water phantom systems. All detectors are from our in-house production and have been extensively tested to meet the highest criteria in radiotherapy dosimetry.
Air Ionization Chambers
All compact chambers are 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.
CC01 and CC04
CC01 and CC04 are the conventional ionization chambers for measurements of small fields and of ranges with high dose gradients, e.g. stereotactic fields.
CC08 / CC13
CC08 is used for customized applications during manufacturing and installation of linear accelerators (e.g. “Buddelship”).
CC13 is the standard chamber for clinical use in water phantoms and for output factor measurements.
CC25 is mainly used for quality assurance in air and for low dose measurements in water phantoms.
The CC13-S is replacement for RK chamber used in RFA phantoms.
Parameters of the CC13-S are similar to CC13.
Farmer Type Chambers
All farmer type chambers are 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.
FC65-G is the standard reference detector for reference dosimetry and scientific applications.
FC65-P can be used for all routine applications.
FC23-C yields higher precision in measuring of isodose contours.
Plane Parallel Chambers
All plane parallel chambers are designed for measurements with high reproducibility in air, in solid or in water phantoms.
PPC05 and PPC40
PPC05 and PPC40 are suitable for absolute dosimetry of electron, photon and proton beams in radiotherapy.
The NACP is designed according to recommendations of the Nordic Association of Clinical Physicists(NACP), Acta Radiologica Oncology 19,55.
The chamber is used for absolute dosimetry of electron beams 2-50 MeV. A thinner front wall minimizes contamination of the beam and allows measurements at shallow depth and high accuracy even at low electron energies is guaranteed.
The IBA Dosimetry diode detectors are designed for depth dose and profile measurements in water and in air and for output factor measurements in small photon beams.
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.
