Patent Number Title Of Patent Date Issued
6770885 Systems and methods for detecting ionizing radiation with an imaging system August 3, 2004
A radiation imaging system comprising a scintillator, an imager array, and a lamination layer. Lamination layer bonds and optically couples scintillator to imager array. Lamination layer is comprised of a lamination material that is substantially free from void spaces. Radiation imag
6724010 Solid state imager having gated photodiodes and method for making same April 20, 2004
A solid state imager is provided that comprises an imaging array of gated photodiodes. The imager comprises a plurality of photosensor pixels arranged in a pixel array, and each of the photosensor pixels includes a photodiode having a sidewall, the sidewall having a gate dielectric layer
6680216 Method of making imager structure January 20, 2004
In an imager having an array of light-sensitive elements and employing striped common electrodes, exposed edges of preimidized polyimide layers above the light-sensitive imaging elements are sealed with the material of the common electrode (e.g., indium tin oxide). Similarly, exposed
6661456 Imaging of pixel defects in digital detectors December 9, 2003
A method and apparatus for displaying an image generated by at least one detector of an imaging unit are disclosed herein. The method includes creating a pixel map identifying locations of bad pixels in an array of pixels in the image detected by the at least one detector, linking the
6465824 Imager structure October 15, 2002
In an imager having an array of light-sensitive elements and employing striped common electrodes, exposed edges of preimidized polyimide layers above the light-sensitive imaging elements are sealed with the material of the common electrode (e.g., indium tin oxide). Similarly, exposed
6465286 Method of fabricating an imager array October 15, 2002
RD-25953-17-A method of fabricating an imager array having a plurality of pixels is provided in which each pixel is made up of a photodiode and a corresponding thin film transistor (TFT) switching device, the method including the steps of depositing materials to form the photodiode islan
6455855 Sealed detector for a medical imaging device and a method of manufacturing the same September 24, 2002
An apparatus and method are provided for sealing a light imaging array and scintillator of an imaging device which prevents light or moisture from entering the sealed cavity while controlling the lateral expansion of the epoxy material during construction. The seal is formed by dispensin
6422750 Digital x-ray imager alignment method July 23, 2002
In a digital x-ray imager alignment method, a low exposure x-ray image of an object is taken. The dose is sufficient to create an image of an object and alignment bars on an antiscatter grid. The relative position of the alignment bars on the image is measured. The relative angle of the
6414315 Radiation imaging with continuous polymer layer for scintillator July 2, 2002
A radiation imager includes a light sensitive imaging array, a barrier layer formed over the light sensitive imaging array, a continuous polymer layer formed over the barrier layer, and a scintillator formed directly on the continuous polymer layer. The continuous polymer layer improves
6396046 Imager with reduced FET photoresponse and high integrity contact via May 28, 2002
A light block material disposed over the photosensitive region of a switching device (e.g., TFT) of a radiation imager is disclosed. The light block material prevents optical photons emitted from a scintillator from passing into the switching device and being absorbed. Cross-talk and noi
