ABSTRACT
Computed tomography (CT) is an essential imaging modality. To solve the problem caused by increasing radiation exposure from CT scanner and to elevate the image quality, we aimed to apply the general objective image quality methods in CT image quality evaluation. After analyzing the perceptual features of CT image, we tested several popular objective image quality metrics, which focus on the similar perceptual features, on the CT image of phantom and animals. Experiments for verifying the feasibility were carried out. Compared with the subjective ratings from two professional radiation physicians, the complex wavelet-based structural similarity metric presents the better prediction results of the image quality.
