Estimation of Detect Ability of Gas Cavity Using Disc Phantom in Industrial Computed Tomography

摘要

The techniques dedicated for the estimation of detect ability of gas cavity in industrial Computed Tomography was introduced in this paper. This paper represents the principle and recent approach of disc phantom method, and experiments were carried out using this method, then the approximate formula was generalized after theory analyses. At last, the result shows that the method is useful for the estimation of detect ability of gas cavity in industrial Computed Tomography image.
