The CIRS Model 008 Dynamic Thorax Phantom is designed to investigate and minimize the impact of organ motion and patient positioning errors in radiation therapy.
Major components of the system include a tissue equivalent thorax phantom, a precision motion actuator, and controller with pre-set motion profiles.
Three-dimensional motion to the tumors in the phantom body are achieved by the actuator applying synchronized linear and rotational motion to a moving rod. Sinusoidal and other complex motions can be achieved with sub-millimeter accuracy and reproducibility.
The Thorax Phantom is manufactured from materials that mimic tissues within 1% from 50keV to 25MeV. The phantom accurately represents average human thorax anatomy in shape, proportion and structure. Tumors of various size, shape and density can be positioned within the lungs and means are provided for placement of various detectors directly within the tumor volume.
