Title: Innovations of Russell H. Nord

Introduction

Russell H. Nord is a notable inventor based in Fort Atkinson, Wisconsin, who has made significant contributions to the field of medical imaging. With a total of seven patents to his name, he has focused on developing advanced technologies for calibrating dual energy x-ray machines. His work has greatly enhanced the accuracy of body fat measurements and bone density assessments.

Latest Patents

One of Nord's latest patents is a variable composition phantom that simulates varying degrees of body fat for dual energy x-ray machine calibration. This invention provides a limited number of calibrated plates made from materials that mimic different body fat percentages. By combining these plates, a range of simulated body fat compositions can be precisely obtained. The plates can be customized in size to cover a broad area and may include a high-density end cap that triggers automatic region of interest detection for certain scanner systems.

Another significant patent is a spine phantom that simulates cortical and trabecular bone for the calibration of dual energy x-ray bone densitometers. This invention simplifies the construction of the phantom by equating the complex density variations of the spine to a set of easily machined flat surfaces of varying thicknesses. The spine phantom includes a vertebra-simulating body with a base surface that is perpendicular to the x-ray beam, defining an intervertebral section, a composite bone section, and cortical wall sections. These sections simulate the cartilage, cortical, and trabecular bone regions of a human spine. Additionally, the vertebra-simulating bodies can be embedded in an acrylic block lined with a vinyl layer to represent a human spine surrounded by soft tissue.
