This work was carried out to evaluate the basic performances for 4D CT, which employed continuously rotating conebeam. The performances were evaluated with the same method as the conventional CT, because the standard method of evaluating 4D CT has not yet been established, and we think this result was helpful to establish it. 4D CT can give dynamic volume imaging data continuously and with high-speed. The results were isotropic except for the evaluation of distortion in which small distortions gradually appeared as coming off the center of phantom in longitudinal direction.

4D CT will enable us to apply to not only new diagnoses but also examinations and treatments, which need real-time observation. In this study we evaluated basic performances of 4D CT-scanner and compared them with those of a state-of-the-art CT-scanner.
