Super-resolution in Single-coil Multiple Image Reconstruction Technique
Ito s, Fukaya h, Liu n, Yamada Y, Tanaka k
This paper presents the resolution improvement method for the partially high-resolution image in multiple image reconstruction technique. The signal obtained in the phase-scrambling Fourier imaging technique can be transformed to the description of Fresnel transform equation. Therefore, an image can be reconstructed by inverse Fresnel transform as well as by standard inverse Fourier transform. By combining these two reconstructed images, we can obtain an image that has a higher resolution than standard imaging technique in the center of image. To improve the resolution, super-resolution technique was applied, and it was shown that resolution was fairly improved by a small number of iterations.
