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.
Target and surrogate motion are independently controlled with CIRS Motion Control Software. The graphical user interface
provides an unlimited variety of motions while simplifying the operation of the Dynamic Thorax Phantom to an intuitive
level. Patient specific profiles are easily imported and there is no need to make hardware adjustments or have special
programming skills.
