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.

In 1982, PI introduced the first 1.0T magnetic resonance imaging (MRI) unit. In 1998, it acquired the CT division of Elscint Ltd. In 1999, the company changed its name to Marconi Medical Systems. In 2001, Philips Electronics bought Marconi Medical Systems for $1.1 billion.
