Latest Patents
One of his latest patents is titled "High-speed electric tomography." This invention involves an apparatus for electrical impedance imaging of a body, which includes an array of multiple electrodes. Each electrode is connected to an adjustable amplitude precision current source of fixed frequency and an oversampling type digital voltmeter. The current amplitudes are set to produce a series of spatial current patterns, all orthogonal to each other, and each applied for only a short time interval while voltages are measured. The voltage and current values are then used to create real and reactive impedance images of the interior of the body.
Another significant patent is "Current patterns for electrical impedance tomography." This method utilizes an adaptive repeated series of calculations and measurements to determine the best current pattern for a body with initially unknown internal conductivity. The goal is to produce the best electrical impedance image for the body. Initially, an arbitrary current pattern and conductivity are utilized to generate a voltage pattern, which is measured and compared with the theoretical voltage pattern based on the arbitrary conductivity and current patterns. When both the current pattern and the conductivity closely match values derived from measurements, the voltage pattern is used to produce the image.
