UNCOMPROMISING QUALITY

For assessing pinpoint radiation fields for IMRT, stereotactic, orthovoltage x-rays, stereotactic, and superficial skin therapy

EXRADIN MICROCHAMBERS ARE IDEAL FOR SMALL FIELD SIZE IMRT APPLICATIONS

The Model A14SL Microchamber is designed specifically for assessing radiation fields encountered in IMRT and stereotactic radiosurgery. The Model A14SL thimble chamber is the Slim-Line version of Model A14. It has the exact same internal dimensions and collecting volume as the Model A14, yet the entire chamber has the uniform diameter of 6.4 mm (0.250 in), which is ideal when fitting it into a small phantom. The Microchamber is capable of measuring extremely small field sizes of 4 mm by 6 mm, allowing for exceptional spatial resolution and exact pinpoint beam profile characterization.

FAST, PRECISE MEASUREMENTS

The chamber vents through a flexible tube that surrounds the triaxial cable, ensuring the collecting volume is in pressure equilibrium with the surroundings. The design assures there are no stem or voltage soakage effects, providing precise and reliable measurements.

DURABLE CONSTRUCTION, BUILT TO LAST

The Model A14SL is constructed of rugged C552 Shonka air-equivalent plastic, providing excellent conductivity and years of reliable use.
