Latest Patents

One of Schaetzing's latest patents is a method and apparatus for automatic tonescale generation in digital imaging. This invention provides a robust technique for adaptively generating tonescale transformation functions that are effective across various imaging systems, exposure conditions, and body parts. The method utilizes the histogram of the digital input image, the cumulative distribution function of the histogram, and the entropy of subsections of the histogram to create a final tonescale transformation. By dividing the histogram into regions of interest, low-signal foreground, and high-signal background, the tonescale is constructed to be linear over the region of interest while smoothly transitioning to nonlinear portions in the other regions. This adaptive approach ensures that the final image meets specific output density constraints, optimizing its diagnostic utility.

Another significant patent involves a rule-based technique to automatically determine the final scan gain in storage phosphor radiography. In this process, a storage phosphor plate absorbs x-ray energy and emits light when stimulated by visible light. The invention provides a method for setting the amplification gain during the scanning process by utilizing a preliminary read-out (pre-scan) to automatically determine the final scan gain. This technique maximizes the information extracted from the phosphor, enhancing the quality of the radiographic image.
