CIRS Model 002HN
IMRT Phantom - Head and Neck
Complete QA: From CT Imaging, to Dose Verification
The CIRS 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.
The CIRS 002HN phantom 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 Model 002HN phantom is manufactured
from unique proprietary materials that faithfully mimic bone and water within
1% from 50 keV to 25 MeV.
The phantom is circlular in shape, and 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 002HN phantom also supports film
dosimetry with not only standard ports film dosimetry,
and not only standard radiographic films but also Gaf-Chromic ® radiographic
films but also Gaf-Chromic ® media.
Optional inserts are available to support
a variety of other detectors including TLDs, MOSFET, and diodes.
The Model 002HN accommodates one
Ready PackTM 10"Ã‚Â x 12"Ã‚Â films in transverse orientation, two
radiochromic or radiographic 10 x 10 cm films in transverse orientation,
and a stack of thirteen radiochromic films precut to 63.5 x 63.5 mm in three different orientations.
The Model 002HN includes five
different Electron Density reference plugs which can be interchanged
in five separate locations
within the phantom.
The surface of the 002HN Phantom
is etched with grooves to ensure proper orientation of the CT slices and accurate
film orientation of the CT slices and accurate film to plan registration.
An optional cranial bone ring is also available.
