Title: The Innovations of Ronald G Walters

Introduction

Ronald G Walters is a notable inventor based in Aurora, OH (US), recognized for his contributions to the field of computerized tomography. With a total of six patents to his name, Walters has made significant advancements in imaging technology that enhance diagnostic capabilities.

Latest Patents

One of Walters' latest patents is the "Method and apparatus for back projecting image data into an image matrix." This invention includes a back projector designed to assist in the reconstruction of computerized tomography projection data. It provides a fast and universal back projection system that can accommodate virtually any scanner geometry. The back projector operates based on an algorithm that scales an image matrix pixel location to determine a pointer into a projection data memory. A linearization memory contains pointers into this projection data memory, and the pixel location is used to determine the proper location within the linearization memory, preferably using a linear interpolation process. The projection data is extracted using a similar interpolation process.

Another significant patent is the "Dual energy computerized tomography system." This invention describes a dual energy method for CT scanning, where scanning is performed at low and high energy levels, each at a preselected dose level. Detected electronic signals are digitized, and a look-up table generates a pair of values from each pair of signals, one representing a photoelectric component and the other a Compton component. Each value undergoes spatial filtering by a convolution filter function designed to enhance the signal-to-noise ratio in the resultant combined image.
