Title: Innovations by Hans Roehrig
Introduction
Hans Roehrig is a notable inventor based in Tucson, Arizona, recognized for his contributions to imaging technology. He holds two patents that focus on enhancing the quality of x-ray and gamma-ray images. His work has significant implications in fields such as radiation therapy, dental imaging, and industrial imaging.
Latest Patents
One of his latest patents is titled "Image spot noise reduction employing rank order." This invention addresses the issue of white spot noise in x-ray or gamma-ray images produced as an array of pixels. The method involves producing two or more successive images in registry and inspecting the pixel values at each location. By selecting the lowest ranking pixel value for each pixel location, the output image is substantially free of spot noise. This technique is particularly beneficial for portal imaging in various medical and industrial applications.
Another significant patent is "CCD and phosphor screen digital radiology apparatus and method for high." This system is designed to locate regions of varying density in biological tissue, such as the breast. It includes a controlled x-ray source, a phosphor screen, a cooled, slow scan CCD camera, and a variable magnification optical system. The control system digitizes signals from the CCD camera to produce digital data representative of tissue densities. This invention aids in the rapid and precise identification of high-density breast tissue, which may indicate tumor or microcalcification sites.
