Raymond Damadian
Damadian is the company's largest shareholder, with 8% of stock worth $6.5 million. Despite owning only 8% of the stock, he maintains almost 100% control of the company through a separate class of shares (Class C) that only Damadian controls 2007. Damadian later collaborated with Wilson Greatbatch, one early developer of the implantable pacemaker, to develop an MRI-compatible pacemaker. He invented a stand-up MRI system and has 15 MRI scanning centers across the United States. There are a number of independent MRI centers that use this technology both in the U.S. and around the world. The company conceived and built the world's first Upright Multi-Positional MRI, which was recognized as The Invention of the Year in 2007 by the Intellectual Properties Owners Association Education Foundation.
History of magnetic resonance imaging
In the 1960s and 1970s the results of a very large amount of work on relaxation, diffusion, and chemical exchange of water in cells and tissues of various types appeared in the scientific literature. In 1967, Ligon reported the measurement of NMR relaxation of water in the arms of living human subjects. In 1968, Jackson and Langham published the first NMR signals from a living animal, an anesthetized rat.
In a March 1971 paper in the journal "Science", Raymond Damadian, an Armenian-American doctor and professor at the Downstate Medical Center State University of New York (SUNY), reported that tumors and normal tissue can be distinguished in vivo by nuclear magnetic resonance ("NMR"). He suggested that these differences could be used to diagnose cancer, though later research would find that these differences, while real, are too variable for diagnostic purposes. Damadian's initial methods were flawed for practical use, relying on a point-by-point scan of the entire body and using relaxation rates, which turned out not to be an effective indicator of cancerous tissue. While researching the analytical properties of magnetic resonance, Damadian created a hypothetical magnetic resonance cancer-detecting machine in 1972. He filed the first patent for such a machine, on March 17, 1972, which was later issued to him on February 5, 1974. Lawrence Bennett and Dr. Irwin Weisman also found in 1972 that neoplasms display different relaxation times than corresponding normal tissue. Zenuemon Abe and his colleagues applied the patent for targeted NMR scanner, on 1973. They published this technique in 1974. Damadian claims to have invented the MRI.
