Abstract
A cone-beam computed tomography (CT) system for a small animal has been widely used in the bio-medical application. This paper introduced simple methods for evaluating a cone-beam CT system using a simple tungsten wire phantom of 10{$\mu}m$ diameter and a water phantom. Slice images and three-dimensional tomography images were obtained through 360 projection views per one sample rotation under stable X-ray tube conditions for a long running time. The cone-beam CT system at a position of a 1.07 magnification showed a spatial frequency of 13.78 lp/mm ($36.2{\mu}m$ spatial resolution) and gave a CNR of 10.33 and a S/N of 5.87 under a tube voltage of 80kV.
