摘要：
Provided herein is a phantom and a phantom system, the phantom including a plurality of blocks combined having different elastic modulus, and thus may be easily manufactured in various shapes, movements, and densities and may exactly imitate movements of a tissue such as in a lung that has high volume change rates and has a high possibility that a position and shape of a tumor may change, thereby providing an effect of being used in replacement of patients when evaluating 4D-CT performance and measuring radiation amounts.
