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.
Mass spectrometry imaging
More than 50 years ago, IMS was introduced using secondary ion mass spectrometry (SIMS) to study semiconductor surfaces by Castaing and Slodzian. However, it was the pioneering work of Richard Caprioli and colleagues in the late 1990s, demostrating how matrix-assisted laser desorption/ionization (MALDI) could be applied to visualize large biomolecules (as proteins and lipids) in cells and tissue to reveal the function of these molecules and how function is changed by diseases like cancer, which led to the widespread use of IMS. Nowadays, different ionization techniques have been used, including SIMS, MALDI and desorption electrospray ionization (DESI), as well as other technologies. Still, MALDI is the current dominant technology with regard to clinical and biological applications of MSI.
