We analysed of the images generated with multi-slice CT in the longitudinal direction (Z) and assessed the noise equivalent quanta (NEQ)evaluation. Evaluation of image quality in NEQ, was possible to accuracy of reappearance in low at high frequency characteristics. In addition, NEQ information was confirmed of usefulness in compared with Winer spectra and MTF method. Examination results suggest that the quantitative analysis in characteristics of image noise and image resolution at multi-slice CT images can provide an optimal parameter for improving quality of images in clinical data.
