Exradin A16 Micropoint Chamber, 0.007cc.

The Exradin micro ion chambers have a superior small-field dosimetry to assess pinpoint radiation in IMRT, stereotactic, orthovoltage, x-rays and superficial skin therapy.

The Model A16 microchamber measures extremely small field sizes (3.4 mm x 3.4 mm); allowing for exceptional spatial resolution and exact pinpoint beam profile characterization.  These attributes make the A16 ideal for stereotactic radiosurgery and IMRT applications.
