Magnetic Resonance Imaging01:24

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Summary

We developed two brain extraction algorithms (BEA) for T2-weighted MRI scans. The 3D-BEA method, utilizing adjacent slice information, significantly outperforms the 2D-BEA and other popular tools for accurate brain extraction.
