IMRT Homogeneous Phantom
Model 002H5

IMRT Homogeneous Phantom - Model 002H5 - Products - CIRS

Complete QA from CT imaging to dose verification

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 15 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.*
 

Features:

  • Check 2D dose distributions (3D distributions optional)

  • Point dose measurements in multiple planes

  • Calibrate film with ion chamber quickly verify individual patient treatment plans*
     

IMRT Verification System

CIRS IMRT phantoms are manufactured from tissue equivalent materials that mimic within 1% from 50 keV to 15 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.

*NOTE: This product or an optional accessory of this product requires a CIRS dosimetry cavity code before an order can be placed. Please refer to the Dosimetry Cavity Codes document to identify the CIRS code for the probe you intend to use with this product.

The CIRS line of IMRT phantoms is compatible with the RIT 113 software for film to plan analysis. GafChromic® is a registered trademark of International Specialty Products, Wayne, NJ.
