Abstract(in English) | MR images have spatial phase distribution due to the inhomogeneities of static magnetic field strength and the difference of magnetic susceptibility. Therefore, it is required to consider the spatial phase variation in the image reconstruction of compressed sensing, however, few studies have been done so far. In this study, we proposed a novel CNN image reconstruction method in which complex images can be reconstructed using real-valued CNN without the estimation of spatial phase variation. Reconstruction experiments showed that image quality was improved in proposed method with higher PSNR and SSIM compared to other reconstruction methods. |
