摘　　要：压缩感知(compressed sensing,CS)是一种通过对k空间进行欠采样来显著缩短图像采集时间的技术,同时采用更新的算法实现原始信号的重构,保证重建图像的质量。将CS应用于MRI中,可以加快成像速度,同时可以保证图像质量,有效减少伪影,有利于疾病的快速诊断。本文从CS技术的应用起源出发,旨在探讨其在脑部、心脏、血管、骨关节成像等全身各部位MRI检查中的临床应用现状,强调其在医学领域的潜在价值,为未来临床实践提供重要见解。Compressed sensing(CS)is a technique that significantly shortens image acquisition time by undersampling the k-space.Simultaneously,it employs advanced algorithms to reconstruct the original signal,ensuring the quality of the reconstructed image.Applying CS to MRI can accelerate imaging speed while maintaining image quality,effectively reducing artifacts,and promoting rapid disease diagnosis.This article starts with the application origin of CS technology,aiming to explore the current clinical applications of CS technology in whole-body magnetic resonance imaging examinations,including brain,heart,vascular,and musculoskeletal imaging.It emphasizes the potential value of CS in the field of medicine,providing crucial insights for future clinical practices.
