The IMRT Thorax Phantom has the same outside dimensions as the IMRT Homogeneous Phantom but includes lung and cylindrical spine. It also allows measurements in midiastinum, lungs and spine.
The IMRT Thorax Phantom is elliptical in shape and properly represents an average human torso in proportion, density, and two-dimensional structure. Measures 30 cm Long x 30 cm Wide x 20 cm Thick.
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.
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.
