Phase Border Removing of MRI Brain Image by Wavelet Transform with Symmetrization Technique

We present a preliminary design and experimental results of phase discontinuity relaxation method for Magnetic Resonance Imaging (MRI) phase images that utilizes wavelet transform algorithm with symmetrization technique. The method is capable of solving ambiguity problem in MRI phase image by removing the border boundary. The key idea of wavelet transform algorithm is to solve the given MRI phase data by operating frequency domain relaxation in coarse grids and transferring the intermediate result into finer grids. In this paper we investigate the possibility of employing this approach for phase image based-MRI application. We also evaluate and compare these processed images with the original image. The application of the proposed method for unborder phase is demonstrated.
