    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: The present disclosure is directed towards a method of changing wireless communication channels in a connected host and client system. For example, in one embodiment, the link quality of a connection is monitored by the host or the client. If the connection has a link quality below a predetermined threshold but remains intact, a channel switch request is sent, synchronization packages are exchanged between the host and client on the current channel, the channel of the system is changed to a new channel, and the system resumes communications on the new channel.

    摘要: In one embodiment, a method for coordinating operation of X-ray detectors in a wireless X-ray system includes detecting multiple wireless X-ray detectors within an operative range of an X-ray base station, the detected X-ray detectors each having one of multiple possible statuses, including an active status corresponding to a designation of the X-ray detector as a desired recipient of radiation during a current X-ray imaging sequence, an inactive status corresponding to a designation of the X-ray detector as not the desired recipient of radiation during a current X-ray imaging sequence, and an unenabled status corresponding to the X-ray detector not being configured to operate with the X-ray base station. The method also includes determining the current status of each detected X-ray detector and displaying on a user-viewable screen a visual indication of the status of each detected X-ray detector.
