Title: Innovations by Kenneth Abend in Medical Imaging

Introduction

Kenneth Abend is a notable inventor based in Huntingdon Valley, Pennsylvania, recognized for his contributions to medical imaging technology. With a total of eight patents to his name, Abend has developed innovative methods that enhance the monitoring and analysis of blood flow.

Latest Patents

Among his latest patents is a device and method for mapping and tracking blood flow and determining parameters of blood flow. This invention provides a method for affordable three-dimensional imaging of blood flow using a low-profile, easily-attached transducer pad. It allows for real-time blood-flow vector velocity and long-term unattended Doppler-ultrasound monitoring, even with patient or pad movement. The pad and its associated processor collect and Doppler process ultrasound blood velocity data in a three-dimensional region using a planar phased array of piezoelectric elements. The invention effectively locks onto and tracks points in three-dimensional space that produce locally maximum blood velocity signals. The integrated coordinates from this tracking process are utilized to create a three-dimensional map of blood vessels, which can be displayed for selecting multiple points of interest for expanded data collection and continuous blood flow monitoring. This three-dimensional map also facilitates the calculation of vector velocity from measured radial Doppler.

Another significant patent involves transmitter patterns for multi-beam reception, which similarly enhances medical applications by providing affordable three-dimensional imaging of blood flow. The design of the thinned array, which features greater than half-wavelength element spacing, contributes to the device's affordability and low profile. The full aperture is utilized for both transmission and reception, ensuring no loss of sensitivity or dynamic range. By extending the physical array without increasing the number of active elements, the angular field of view is increased, further enhanced by utilizing a convex non-planar surface.
