High Resolution 3-D Sonic Imaging System

We propose to study and simulate an innovative approach to ultrasound imaging for medical diagnostics. It is based on the spatial encoding of broad beam continuous wave echo returns rather than traditional pulsed echo techniques. This new technology promises to significantly improve the ability of physicians to diagnose ailments while lowering testing costs. By extracting a frequency encoded signature from each imaged point with a matched filter corresponding to the points 3-D location, the system carefully sidesteps most of the militations of current ultra-sound systems. Objects significantly less than 1mm in size can be imaged as the system is not limited by beam forming ability. Using a continuous wave signal, a wide bandwidth return, and a lower average frequency the system offers greater depth penetration and improved tissue contrast. The volumetric nature of the technology allows the system operator to directly control a variety of real-time 3-D and 2-D imaging modes for unparalleled flexibility. Anticipated Benefits: The proposed sensor technology should see widespred use since it offers image quality comparable to MRI and CATSCAN modalities with the flexibility and low cost of ultrasound. The system could also significantly improve battlefield daignostics by providing a complete noninvasive imaging system that is portable, easy-to-use and effective for most battlefield injuries.
