| IMRT Thorax Phantom. |
 | 
Complete QA from CT imaging to dose verificationFeatures The CIRS Model 002LFC IMRT Thorax 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 002LFC is elliptical in shape and properly represents an average human torso in proportion, density and two-dimensional structure. It measures 30 cm long x 30 cm wide x 20 cm thick. The phantom is manufactured from unique proprietary materials that faithfully mimic water, bone and lung within 1% from 50 keV to 25 MeV. Tissue equivalent interchangeable rod inserts accommodate ionization chambers allowing for point dose measurements in multiple planes within the phantom. Hole placement allows verification in the most critical areas of the chest. One half of the phantom is divided into 12 sections, each 1 cm thick, to support radiographic or GafChromic® film. Optional 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 marked for ease of laser alignment. Optional CT markers are available to ensure accurate film to plan registration. |

An 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® or standard ready-pack films. Click Here to download ION Chamber Cavity Codes for Dosimetric Phantoms. |
