Latest Patents

One of his latest patents is titled "Real-time two-dimensional resistance and pulsatility mapping." This invention provides a method and apparatus for determining resistance and pulsatility indices of material flow, such as blood in the human body. The technology can be implemented in a color flow module within an ultrasonic imaging system, allowing for the display of pulsatility or resistance indices in two dimensions. This innovation aids in distinguishing between veins and arteries and detecting pathological elevations of vascular resistance during clinical surveys. The resistance index is calculated from the ratio of a unipolar variation estimate of the flow velocity divided by a peak velocity.

Another significant patent is the "Method and apparatus for three-dimensional flow lumen imaging." This invention generates three-dimensional images of flow structures and their flow lumen using ultrasound techniques. It utilizes a border between flow and non-flow regions to create a three-dimensional image of the flow lumen. The images can be viewed in real-time and stored on a machine-readable medium, with the ability to manipulate the three-dimensional images from various viewing angles and positions.
