Abstract
An x‐ray shadow projection microscope using a scannable point source of x‐rays is under development at AMIL‐ARTS, SUNY at Buffalo. Considering the characteristics of the x‐ray microscope of AMIL‐ARTS and the limitations of Feldkamp's cone‐beam reconstruction algorithm, a general cone‐beam image reconstruction algorithm has been developed. In x‐ray microscopy, many specimens are plate‐like. The reconstruction of a plate‐like specimen appears to be a limited angle problem. A novel method is presented to reconstruct a plate‐like specimen using the general cone‐beam reconstruction algorithm. Shepp and Logan's head phantom is used in validating this method. A method for synthesizing projection data of ellipsoids is described. Typical simulation results are given.
