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 performing an X-ray exposure via an X-ray radiation source responsive to a source controller. The method also includes sampling X-ray image data via a digital detector without communication of timing signals from the source controller. The method further includes combining the sampled X-ray image data of at least one imaging frame or two or more imaging frames with at least one of the frames spanning a duration in which the exposure occurred, to produce X-ray image data capable of being reconstructed into a user-viewable image.

摘要： The effects of electromagnetic interference (EMI) on X-ray image data is corrected by characterizing the EMI and processing the image data to subtract the EMI effects from the image data. The X-ray image data, along with offset data, are collected in a conventional manner, affected by EMI if present, and EMI-characterizing data is immediately collected thereafter by disabling rows of a digital detector (FET off). The EMI-characterizing data, then, is not affected by the presence of image data, and can be used to characterize the amplitude and frequency of the EMI. The EMI-characterizing data is assured of being in phase with the collected image and offset data due to its collection in the same image acquisition sequence immediately following the collection of image and offset data. Artifacts due to the presence of EMI are thus eliminated from reconstructed images based upon the corrected data.

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.
