This study introduces a novel constrained reconstruction technique that exploits both the local correlation of image data across multiple coils and the inherent non-local self-similarity property of images. Our approach is based within a non-local total variation regularization framework. The proposed method is applicable to both compressed sensing and parallel imaging, and demonstrates substantial advantages with regard to high levels of noise.
