摘要: A method for imaging unknown objects in a computed tomography (CT) system, comprising determining ray gain known object is provided. CT reconstruction performed with the to obtain reconstructed values. Ideal values are obtained pixels of object. An error related difference between and ideal generated. estimated that reduces error.
