A comparative study of assessment methods for medical image quality

Image reconstruction plays an important role in medical imaging technology, the quality of reconstructed image will directly affect the results of clinical diagnosis. How to assess the quality of the image is an attractive research topic. In this paper, a comparative study of quality assessment for medical image with seven common algorithms was presented, the images were reconstructed from the result of the GATE (Geant4 Application for Tomographic Emission) simulation of PET/CT imaging, then the algorithms are used to assess the reconstructed image. The results of comparative experiment show that the algorithms have their individual characteristics to assess image quality, appropriate method or a comprehensive method should be selected for the assessment of reconstructed medical image depending on clinical practice.
