Title: Ivan Romadanov and Adaptive Dual-Energy X-Ray Imaging

Introduction

Ivan Romadanov is an inventor associated with Dalhousie University in Halifax, Canada. His patent work addresses adaptive dual-energy X-ray imaging, using pre-calibrated weighting factors to improve material cancellation and noise reduction.

Latest Patents

Romadanov is credited with one patent: “Adaptive Dual-Energy X-Ray Imaging Using Pre-Calibrated Weighting Factors.” The method first calibrates a fitting model using high- and low-energy images of a step phantom. It identifies regions of interest containing overlapping materials, measures their average image intensities, and determines material-cancellation and noise-cancellation weighting factors for each material and region.

The calibrated model is then applied to images of a subject. It generates subject-specific weighting-factor maps, which are used with the high- and low-energy images to support adaptive material cancellation and noise reduction.
