Fonar Corp. v. General Electric Co.
"Fonar" was a dispute between medical device manufacturer Fonar Corporation and General Electric over Fonar's patent on MRI technology. Fonar's founder, Raymond Damadian, was issued U.S. Patent 3,789,832 (priority date 1972-03-17) for an "apparatus and method for detecting cancer in tissue" using the magnetic resonance of atoms. Damadian's patent was the first patent on an MRI machine issued in the United States. Also at issue was a later patent, U.S. Patent 4,871,966 issued in 1989, covering a method for obtaining MRI images of multiple planes at different orientations in a single scan. GE is a major manufacturer of MRI scanners, and Fonar sued GE for infringing these patents by producing its scanners as well as inducing others to infringe.

The team, consisting of members of the departments of Radiology and Otorhinolaryngology and the neurosurgical service at BWH and industrial collaborators from General Electric Medical Systems, developed and built an entire operating suite built around a specially-designed 0.5 Tesla MRI scanner that allowed ongoing patient scans to be obtained during a surgical procedure. Information from the scans, including imaging data registered with three-dimensional models created from pre-operative imaging, was available to the surgical team to help guide the procedure. The system became known as MRT (for Magnetic Resonance Therapy) at BWH and commercialized by GE Medical Systems as the GE Signa SP.
