IMRT Pelvic 3D Phantom

Model 002PRA

The CIRS Model 002PRA IMRT Pelvic 3D Phantom for film and ion chamber dosimetry is designed to address the complex issues surrounding commissioning and comparison of treatment planning systems and complete system QA from CT imaging to dose verification.

Our CIRS Pelvic 3D Phantom properly represents human pelvic anatomy in shape, proportion and structure as well as density. This enables thorough analysis of both the imaging and dosimetry system. Elliptical in shape, the phantom approximates the size of an average patient and has a tissue equivalent three-dimensional skeleton. It’s constructed of proprietary tissue equivalent epoxy materials.

The Model 002PRA includes four different Electron Density reference plugs which can be interchanged in five separate locations within the phantom. The surface of the phantom is etched with grooves to ensure proper orientation of the CT slices and accurate film to plan registration.

  • Verify heterogeneity corrections
  • Correlate CTU to electron density
  • Check dose distributions in sensitive areas
  • Check depth doses and absolute dose
  • 2D and 3D isodoses
  • Calibrate film with ion chamber*
  • Verify individual patient treatment plans

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.

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.
