Latest Patents

Foster's latest patents focus on the development of filmless photon imaging apparatus and sensor plates. These inventions are particularly effective in high-resolution mammography and other medical imaging applications. The sensor plates and apparatus provide rapid production of high-resolution images that exhibit higher sensitivity and a wider dynamic range than contemporary X-ray systems. The novel sensor plate structures enhance image quality with increased sensitivity, a dual plate design that improves pixel read-out speed, and the ability to produce differential dual energy images. Additionally, electrically isolated segments allow for concurrent reading of multiple pixels, significantly reducing overall image processing time. The plates utilize a homogeneous photoconductive material, such as amorphous selenium, and are read by exposing each pixel-sized area to a small diameter scanning light beam. This innovative design promises low-cost manufacturing of both sensor plates and associated apparatus. The application of electric fields during plate preparation, exposure, and read-out further enhances sensor plate performance. A unique optical system employing an elongated light source within a rotating drum enables the scanning of precisely-positioned light beams across the sensor, achieving variable resolution operation by adjusting slit and beam widths.
