Superior small-field dosimetry to assess pinpoint radiation in IMRT, stereotactic, orthovoltage, x-rays and superficial skin therapy.

 

Exradin A26 Ion Chamber

Experience the same measurement quality in the only micro chamber that was designed to meet reference class criteria.

  • Rapid settling
  • Stable, reproducible measurements
  • Realistic and meaningful ion recombination corrections
  • Minimal polarity dependence
  • Minimal energy dependence
  • The only micro chamber that was designed to meet reference class criteria
  • Also available in MR compatible version.

 

Exradin A16 Ion Chamber

The Model A16 microchamber measures extremely small field sizes, allowing for exceptional spatial resolution and exact pinpoint beam profile characterization. These attributes make the A16 ideal for stereotactic radiosurgery and IMRT applications.

The A16 microchamber is the smallest ION chamber in the world.

 

Exradin A14SL Ion Chamber

The Model A14SL is capable of measuring extremely small field sizes, allowing for exceptional spatial resolution and exact pinpoint beam profile characterization. This helps assess radiation fields during IMRT and stereotactic radiosurgery.

 

Exradin A14 Ion Chamber

The Model A14 microchamber has the exact internal dimensions and collecting volume as the Model A14SL, yet a larger overall diameter is ideal for use in solid phantoms.View Exradin® A14 Ion Chamber, Microchamber, 0.015cc
