The IMRT Head and Neck Phantom is circular in shape and approximates the average cranial diameter of 16cm. A bone equivalent rod can simulate the c-spine and an empty hole can simulate the trachea. 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.
The IMRT Head and Neck Phantom accommodates one Ready Pack™ 10” x 12” film 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 IMRT Head and Neck Phantom has four optional 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. An optional cranial bone ring is also available.
