| Outline of Final Research Achievements |
Recently in the MR imaging area, MR fast imaging techniques and data image reconstruction techniques using new information technology including compression sensing (CS) are being introduced. Many of these techniques involve nonlinear calculation processing, and how to evaluate the image quality of the obtained images was a challenge. In this research, we aim to evaluate the image quality of nonlinearly processed MR images by utilizing conventional linear evaluation tools such as noise power spectrum (NPS) and modulation transfer function (MTF). We have tried to establish the measurement method and evaluate some nonlinear processed images.
