摘要：

A deformable phantom was developed to aid in quality assurance for dynamic imaging and targeting techniques in radiation therapy. Made of simple materials combined with standard components for imaging, and motion experiments, this phantom can be relatively easily constructed and used for both diagnostic imaging and dosimetry. Repeat imaging studies indicate that the phantom meets criteria of relative attenuation, deformation, and reproducibility of configuration, necessary for quality assurance of radiographic and tomographic targeting.
