美國(guó)CIRS 002LFC胸部體模產(chǎn)品簡(jiǎn)介：
The CIRS Model 002LFC IMRT Thorax 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 002LFC is elliptical in shape and properly represents an average human
torso in proportion, density and two-dimensional structure. It measures 30 cm
long x 30 cm wide x 20 cm thick. The phantom is constructed of proprietary
tissue equivalent epoxy materials. Linear attenuations of the simulated tissues
are within 1% of actual attenuation for water and bone, and within 3% for lung
from 50 keV to 15 MeV.
Tissue equivalent interchangeable rod inserts accommodate ionization chambers
allowing for point dose measurements in multiple planes within the phantom. Hole
placement allows verification in the most critical areas of the chest. One half
of the phantom is divided into 12 sections, each 1 cm thick, to support
radiographic or GafChromic? film. 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 marked for ease of laser alignment. CT markers are included to
ensure accurate film to plan registration on the center film.

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? 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.
