MR PARTIAL K DATA IMAGE RECONSTRUCTION METHOD BASED ON COMPLEX SINGULAR SPECTRUM ANALYSIS

摘要

A MR partial K data image reconstruction method based on complex singular spectrum analysis is provided, which includes: firstly establishing a MR image mathematics model and a complex singular spectrum analysis model of a complex coefficient weighted singular function, executing the model parameters estimation from the partial K data information, finally reconstructing the MR image using the MR image mathematics model and the complex singular spectrum analysis model. By using the MR partial K data image reconstruction method based on complex singular spectrum analysis, the scanning time can be saved and fast imaging can be realized, so as to provide high quality of reliable image information for the medical NMR detecting. The image error can be efficiently reduced, and the original MR image also can be exactly displayed.
