MRI高速撮像の進展:～画像化の原理から圧縮センシングまで～  [in Japanese] Development of fast imaging techniques in MRI:– From the principle to the recent development –  [in Japanese]

The purpose of this paper is to review the development of fast imaging techniques in MRI. After the brief introduction of the principle of Fourier transform MRI, conventional fast imaging techniques mainly based on the improvement of pulse sequences are described. Next, further fast imaging techniques such as parallel imaging, <i>k-t</i> imaging technique, and finally, recently developed compressed sensing (CS) MRI techniques are discussed.
