Introduction
The IMRT (Intensity-Modulated Radiotherapy) Phantom for Film and Ion Chamber Dosimetry is designed to address the complex
issues surrounding commissioning and comparison of treatment planning systems while providing a simple yet reliable method for
verification of individual patient plans and delivery.
The phantoms are elliptical in shape. They properly represent human anatomy in size and proportion. The phantoms are manufactured
from a unique proprietary material that faithfully mimics water within 1% from 50 keV to 25 MeV.
The phantoms also support radiographic or GAFCHROMIC ® film at mid-plane in the phantom for analysis of dose distributions.
Optional inserts are available to support a variety of other detectors including TLD’s, MOSFET, and diodes.
The surfaces of the phantoms are etched for ease of laser alignment, and CT markers ensure accurate film to plan registration.
