IMRT Homogeneous Phantom

Send Your Inquiry:

The CIRS Model 002H5 IMRT 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 002H5 is homogeneous and elliptical in shape. It properly represents human anatomy in size and proportion. It measures 30 cm long x 30 cm wide x 20 cm thick (PA). The phantom is constructed of proprietary tissue equivalent epoxy materials. Linear attenuations of the simulated tissues are within 1% of actual attenuation for bone and water from 50 keV to 25 MeV. Water equivalent interchangeable rod inserts accommodate ionization chambers allowing for point dose measurements in multiple planes within the phantom.* The phantom also supports radiographic or GafChromic? film at mid-plane in the phantom for analysis of dose distributions. Additional inserts are available to support a variety of other detectors including TLD¡¯s, MOSFET, and diodes. Handling, assembly and proper orientation of the phantom is made easy with the use of a unique alignment base and holding device. The surfaces of the phantom are etched for ease of laser alignment, and CT markers ensure accurate film to plan registration.* CIRS IMRT phantoms are manufactured from tissue equivalent materials that mimic within 1% from 50 keV to 25 MeV for accurate simulation from CT planning to treatment delivery. The interchangeable rod design allows the phantom to accommodate a multitude of dose measurement devices such as ion chambers, TLD, diodes and MOSFET’s in the same location within the phantom.* Phantom cross sections accommodate GafChromic(r) or standard ready-pack films.
