Product Description

Complete QA from CT imaging to dose verification
  • 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
Model 002HN 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.

It properly represents human head and neck anatomy in shape, proportion and structure as well as density. This enables thorough analysis of both the treatment planning and delivery systems. 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 circular in shape, approximates the size of an average patient. 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 Gaf-Chromic® media. Optional inserts are available to support a variety of other detectors including TLD's, MOSFET, and diodes.

Accommodates one Ready Pack 10" x 12" films in transverse orientation, two radiochromic or radiographic 10 x 10 cm films in transverse orientation and a stack of thirteen radiochromic films pre-cut to 63.5 x 63.5 mm in three different orientations.

The surface of the phantom is etched with grooves to ensure proper orientation of the CT slices and accurate film to plan registration.

Model 002HN Includes:
  • One (1) Water equivalent homogeneous section drilled to accommodate rod inserts (15cm)
  • Two (2) Film slabs, 1cm, film cavity 10 x 10 cm with a set of CT to film fiducial markers
  • One (1) Cavity slab, 6.4 cm, to accommodate Film stack or gel cassette
  • One (1) Film Stack for small volume 3D image reconstruction
  • Two (2) Spacer slabs, 1cm
  • One (1) Spacer slab, 2cm
  • One (1) End slab, 1cm
  • One (1) End slab, 1.6 cm
  • Five (5) Water equivalent solid rod inserts
  • One (1) Bone equivalent solid rod insert
  • One (1) Alignment Base
  • One (1) Holding device
Optional Accessories: Set of Four Electron Density Reference Plugs (Item 002ED), Gel dosimetry cassette (Item 002GC), Set of CT to film fiducial markers for additional interfaces (Item 002CTF)
