Simple 3D validation experiments for PRESAGETM /optical-CT dosimetry

Published

Journal Article

Detailed studies of the basic dosimetric properties of small volumes of PRESAGETM have confirmed its promise as a new material with enhanced properties for 3D dosimetry. PRESAGETM is a transparent polyurethane material containing a radiochromic leucodye. Principle advantages include a relative insensitivity of the dose response to atmospheric exposure, and a radiochromic optical contrast which is light absorbing rather than light-scattering (peak optical density change is at ∼633 nm). The absorptive nature of the contrast is more amenable to accurate dose read-out by optical-computed-tomography. This work represents our first feasibility tests of large volumes of PRESAGETM for dosimetric validation of radiation treatments. © 2006 IOP Publishing Ltd.
