Clinical Application of Compressed Sensing MRI

Abstract

MRI imaging time can be shortened by speeding up using the compressed sensing method. And it can be used with the conventional parallel imaging method at the same time. One weakness of the compressed sensing method is that it takes a long time to reconstruct the image, although it takes short time to obtain the image data. However, this point has also been shortened to the extent that it does not become a problem in clinical use by the development of image reconstruction systems using GPU units in recent years. The range of applications of the compression sensing method includes 3D imaging (can be accelerated in the plane and slice directions), dynamic imaging (can be accelerated in the time axis direction), cardiac MRI, and upper abdomen with respiratory motion MRI and pediatric patients and other areas that require short-term examinations are assumed.
