We propose to implement in computer code, and test by computer simulation, a new, fast ultrasound imaging and tissue characterization algorithm, based on our solution of the inverse scattering problem, for application to medical diagnosis. implementation of our algorithm would permit computation of… More

Techniscan, inc. proposes to test the effectiveness of a newultrasound imaging method for the detection and screening ofbreast cancer with real data obtained from a scaled-down, working, scanner model featuring an electronically scanned transducer array. the complete transducer array will be a… More

The long-term objective of this project is to develop a prototype scanning system from which novel and advanced ultrasound scanning systems can be manufactured for the imaging, tissue characterization, and diagnosis of cancer and other diseases. it will give superior images of obstetrical… More

Algorithms will be evaluated by synthic and laboratory generated data. these data will come from test objects and an existing scanners assembled for that purpose.

The primary objectives of this proposal are twofold. The first is to investigate the feasibility ofimplementing certain critical areas of the hardware of an ultrasound scanner, which was developed foruse with inverse scattering theory, as VLSI components. The second is to develop… More

This proposal describes the feasibility and design study of a system for detection and imaging light and dense non aqueous phase liquids (so called LNAPLs and DNAPOLs) that have contaminated soils and aquifers. The system will make use of several modalities to improve combined spatial resolution… More
