Solid-State X-Ray Detector Glass Panel for Digital Mammography
Summary
This article describes a glass panel component of a solid-state X-ray detector. The panel features an array of approximately 1,100 x 900 pixels, each containing a field-effect-transistor (FET) switch and a light-detecting diode. X-rays cause a scintillation material to emit visible light, which is accumulated by the pixels for storage and computer readout. Originally designed for digital mammography, this technology demonstrated significant improvements in dynamic range and readout speed compared to CCD technology.

· 3 pulledEtched onto the panel is an array of about 1,100 x 900 picture elements ("pixels").
X-rays make a separate scintillation material "glow" visible light, reducing the total amount of energy needed to create an image.
Originally intended for digital mammography applications, this glass panel demonstrated enormous dynamic-range and readout-speed improvements over the charge-coupled-device (CCD) technology it replaces.
