The CIRS Model 002PRA IMRT Phantom is designed to address the complex issues surrounding commissioning and comparison of treatment planning systems and verification of individual patient plans and delivery.

Represents human pelvic anatomy in shape, proportion and structure as well as density. This enables thorough analysis of both the imaging and dosimetry system. The phantom is manufactured from unique proprietary materials that faithfully mimic bone and water within 1% from 50 keV to 25 MeV.

The phantom is elliptical in shape, approximates the size of an average patient, and has a tissue equivalent, three dimensional skeleton. Tissue equivalent interchangeable rod inserts for ionization chambers allow for point dose measurements in multiple planes in the phantom and film calibration. The phantom also supports film dosimetry with not only standard radiographic films but also GafChromic® media. Optional inserts are available to support a variety of other detectors including TLD's, MOSFET, and diodes.

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.

Model 002PRA Includes:
  • One (1) 5 cm tissue equivalent reference section for interchangeable ED inserts
  • Ten (10) 1 cm thick contiguous 3D pelvic sections each drilled to accommodate rod inserts
  • One (1) Homogeneous section that accommodates 002FC or 002GC cassettes
  • One (1) Film stack for 3D reconstruction
  • Five (5) Water equivalent rods, 2.5 cm dia. x 5 cm long
  • Twenty (20) Bone equivalent solid disks, 2.5 cm dia. x 1 cm thick
  • Thirty (30) Water equivalent solid disks, 2.5 cm dia. x 1 cm thick
  • One (1) Electron density reference plugs, set of 4 (lung, bone, muscle, adipose)
  • One (1) Alignment Base
  • One (1) Holding device
  • One (1) Set of CT to film fiducial markers
