摘要 Abstract

In 2017, new Magnetic Resonance Imaging (MRI) devices by General Electric and Siemens received US Food and Drug Administration approval, allowing them to be used in the US Health care marketplace.

The manufacturers of both devices say they are using "Compressed Sensing" (CS) and advertise speedups of 8X and 10X over traditional MRI. They say they will eventually spread the use of CS throughout all MRI applications, with a potential scope of 80 million MRI scans per year globally.

This talk will review the applications and the mathematics behind this advance.

It will cover the same territory as the article with the same title in the January 2018 issue of the "Notices of the American Mathematical Society."

The work described was performed by many researchers across several fields.
