CIRS 002LFC IMRT chest phantom

Product details
fromComplete quality check from CT imaging to dose verification

for thin film and ion chamber dosimetryThe CIRS 002LFC IMRT chest model is designed to solve the complex issues surrounding commissioning and comparing treatment planning systems and complete system QA from CT imaging to dose verification.

002LFC is an oval in shape that correctly represents the average human torso in proportion, density, and two-dimensional structure. It is 30cm long x 30cm wide x 20cm thick. The phantom is made from a proprietary tissue-equivalent epoxy material. The linear attenuation of simulated tissue is within 1% of the actual attenuation from 50 keV to 15 MeV for water and bone, and within 3% for lungs.

Tissue-equivalent interchangeable rod inserts accommodate the ionization chamber, allowing point dose measurements in multiple planes within the phantom. The location of the holes allows for verification in the most critical areas of the chest. Half of the model is divided into12 sections, each 1 cm thick to support radiographic film or GafChromic® film. Additional plugins are also available to support a variety of other detectors, including TLDs, MOSFETs, and diodes.

The phantom is easy to handle, assemble and correctly configure using a unique alignment base and fixture. The surface of the phantom is marked to facilitate laser alignment. includeCT marks to ensure accurate film to plan registration on center film.
