Removal of high density Gaussian noise in compressed sensing MRI reconstruction through modified total variation image denoising method()
A modified total variation MRI image denoising method is proposed in this paper. First, the proposed method removes the noise in K-space in compressed sensing MRI reconstruction. Then, the removed K-space data is used as a partial frequency observation in compressed sensing MRI model. The proposed m...
