摘要
Abstract
Objective To design a truncation artifact removal in MR images based on K-space. Methods We extract K-space high-frequency data after artifact processing,add the high-frequency data to the original K-space of artifact images in order to obtain the final complete K-space,and then get the artifact removing effect after reconstruction. Results Through simulated data and clinical picture experiments,MR truncation artifacts are improved. Conclusions The algorithm based on K-space has certain removal effect on truncation artifacts,yet relatively weak,which need to be improved.关键词
