A novel technology based on a new theory is offered for fast high-resolution Magnetic Resonance Imaging (MRI). A critical problem of current MRI machines is the slow speed (20 minutes or more) of imaging. The new technology provides 3 or more times faster and higher resolution 3D images than current technology. MRI machines based on the novel technology capture and process many times more information about target objects than current MRI machines. This is accomplished by using multiple layers of Radio-Frequency (RF) sensor coils placed at different radial distances and orientations. In contrast, current MRI machines are limited to a single layer of RF sensor coils at a single orientation (facing the target object). Therefore, much useful information is overlooked in current technology. A first embodiment of the novel technology and the theory underlying it are described in the US patents listed below.  This embodiment has been validated in preliminary experiments through computer simulations. Improved embodiments of this technology for clinical applications are being developed and evaluated for performance through computer simulations. A related application of this technology is in Single-Photon Emission Computed Tomography (SPECT). Higher resolution SPECT images using lower radiation dosages are provided by this related technology.

This technology is being offered for licensing to industry.

Dr. Muralidhara (Murali) Subbarao is a Professor of Electrical and Computer Engineering at Stony Brook University. His teaching and research interests are Computer Vision, Digital Image Processing, and 3D Medical Imaging. He is the inventor of Field Image Tomography for 3D medical imaging. He is also the inventor of the Depth-from-Defocus technique that uses arbitrarily defocused images (without requirement of any focused image) for three-dimensional shape recovery. He obtained a B. Tech. degree in Electrical Engineering from the Indian Institute of Technology, Madras, and an M.S. and a Ph.D., both in Computer Science, from the University of Maryland at College Park. He has been a Principal Investigator of research grants from both industry and the National Science Foundation. He has authored one book, published over 50 papers in professional journals and conferences, and is the sole-inventor on 9 U.S. patents with 4 of them licensed to industry. Over a dozen students have completed their Ph.D. theses under his supervision. He was a principal member and the Chief Computer Scientist of a start-up company for online image management in 2000-2001.
