Quantitative images quality evaluation of digital medical imaging systems using mutual information

摘要

Information about image quality of medical images is important for imaging system assessment in order to promote the development and manufacturing of state-of-the-art imaging systems. In this paper, we present a method for evaluating physical performance of digital medical imaging systems using mutual information which is a concept from information theory. To validate the proposed method, computer simulations were performed, followed by measuring and comparing the performance of two digital imaging systems. The results demonstrate the usefulness of the proposed method for evaluating physical quality of medical imaging systems.
