    摘要： A system and method for eliminating image artifacts caused by electromagnetic interference (EMI) on a digital x-ray detector. The system and method includes a digital x-ray detector panel having an array of pixels in rows and columns, with a plurality of data lines coupled to the columns of pixels and a plurality of scan lines coupled to the rows of pixels. The system and method uses certain photodiodes in a row of the pixel array for measuring EMI with corresponding scan line and FETs deactivated and eliminating the EMI and image artifacts with the remaining photodiodes in the row with corresponding scan line and FETs activated.

    摘要： A dual function detector device operates in either a normal operating mode or in an EMI correction mode to suppress effects of EMI within the detector. The detector device may be a flat panel x-ray detectors used in x-ray imaging systems. The device has a pixel architecture and panel read-out technique that enables real-time, high spatial frequency measurement of noise induced by electromagnetic radiation on a digital x-ray detector. The measurement can be used to calibrate the detector in real-time to attain artifact-free imaging in all environments, including those that contain temporally and spatially changing electromagnetic fields.

    摘要： An X-ray imaging method includes in a digital X-ray detector including an array of discrete picture elements each including a photodiode and a transistor, applying a first voltage to the transistors of the discrete picture elements. The method also includes preparing for acquisition of X-ray image data by sampling data from the discrete picture elements while applying a second voltage to the transistors of the discrete picture elements not then being sampled, the second voltage being more negative than the first voltage. The method further includes receiving X-ray radiation on the detector from a source. The method yet further includes sampling X-ray image data from the discrete picture elements while applying the second voltage to the transistors of the discrete picture elements not then being sampled.

    摘要： A portable x-ray detector is disclosed that includes an x-ray detecting member and a user removable electromagnetic interference (EMI) shielding member. The user removable EMI shielding member is positioned to at least partially magnetically shield the x-ray detecting member of the portable x-ray detector by redirecting an impinging magnetic field around the x-ray detecting member. The user removable EMI shielding member includes a first magnetic shielding layer, a second magnetic shielding layer, and an intervening material, other than the x-ray detecting member, between the first magnetic shielding layer and the second magnetic shielding layer.
