Recent advances of quality assessment for medical imaging systems and medical images

Abstract

This chapter describes the importance of medical image quality assessment and reviews major factors used for characterizing physical properties of medical images. Recent trends in assessment of medical imaging systems and medical images are also addressed. We will begin with a brief review of the concepts and definitions of some conventional medical image quality metrics and then describe a recently proposed image quality metric. We also provide two clinical applications related to quality assessment for medical images. The first application deals with the improvement of image quality in mammography. The second application addresses the effect of radiation dose reduction on image quality in digital radiography.
