CIRS Dynamic Thorax Phantom                                  


The CIRS Dynamic Thorax Phantom is a precision instrument for investigating and minimizing the impact of tumor motion inside the lung. It provides known, accurate and repeatable three‐dimensional target motion inside a tissue equivalent phantom. It is designed for comprehensive analysis of image acquisition, planning and dose delivery in image‐guided radiation therapy. The phantom body represents an average human thorax in shape, proportion and composition. A lung equivalent rod containing a spherical target and or various detectors is inserted into the lung equivalent lobe of the phantom. The body is connected to a motion actuator box that
induces three‐dimensional target motion through linear translation and rotation of the lung equivalent rod. Motion of the rod itself is radiographically invisible due to its

matching density with the surrounding material. The target and its motion, given
its density difference, can be resolved.
• Complex 3D tumor motion within the lung
• Sub‐millimeter accuracy and reproducibility
• Tissue equivalent from 50 keV to 15 MeV
• Compatible with TLD, MOSFET Dose Gel, Micro‐chamber, PET/CT targets and film
