    摘要： A system for eliminating image artifacts caused by electromagnetic interference (EMI) on a portable digital x-ray detector that is capable of non-contact wireless inductively coupled power transfer and capacitively coupled communication and data transfer. An X-ray imaging system comprising a portable digital X-ray detector inductively and capacitively coupled to a power source and communication device that is coupled to a detector receptacle of the X-ray imaging system when the portable digital X-ray detector is located within the detector receptacle to transfer power from a power supply of the power source and communication device to the portable digital X-ray detector and transfer communication and data between the power source and communication device and the portable digital X-ray detector.

    摘要： Systems, methods and apparatus are provided through which in some embodiments field-effect-transistor (FET) leakage is estimated recursively from a pixel value obtained when the FET is off. The corrected pixel value is then obtained by subtracting the FET leakage estimate from the pixel value read when the FET is on. A weighing factor is introduced for the FET leakage estimation to achieve the balance between image noise and correction resolution.

    摘要： An improved design for a solid state X-ray detector that decreases the amount of moisture diffusion that occurs through seals used to attach a cover to a glass substrate panel, thereby protecting the scintillator from moisture damage. In one embodiment, a second hermetic or semi-hermetic seal is introduced between the scintillator and the outside environment to increase the path moisture must travel to reach the scintillator. In another embodiment, a metal frame, preferably a Kovar® frame, is hermetically or semi-hermetically sealed to the cover and glass substrate panel, thereby decreasing the amount of moisture diffusion through the semi-hermetic seal as compared to the prior art.
