Interactive multiobjective decision-making approach to image reconstruction from projections

Abstract In this paper we propose an interactive multiobjective decision making method based on three criteria functions for image reconstruction. Image reconstruction based on this method is shown to be superior to conventional iterative reconstruction algorithms such as SIRT (Simultaneous Interactive Reconstruction Technique) from the point of view of accuracy of reconstruction. Computer simulation using the multiobjective method shows a significant improvement in image quality and convergence behavior over the conventional algorithms.
