Systems and methods are disclosed for managing autonomous detector and imager subsystems communicating as nodes on a network. In an embodiment, an application server is provided which coordinates use of the autonomous imager and detector subsystems so that appropriate combinations of imagers and detectors are used for particular imaging applications. In another embodiment, the performance of a detector subsystem may be automatically evaluated prior to use, such as by one or more automated routines that monitor or measure factors related to detector performance. Additional systems, methods, and devices are also disclosed.

Application server for use with a modular imaging system

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.

Wireless communication in a medical imaging or monitoring system

A portable imaging detector and a method for operating the portable imaging detector are provided. The portable imaging detector includes a docking connector having a plurality of docking connector contacts. The method includes measuring a voltage at a first docking connector contact, and determining whether the portable detector is (i) operating in a digital cassette mode or is (ii) installed in either a cassette holder or a charging bin using the measured voltage. A detector state monitoring system is also discussed.

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.

Wireless X-ray detector operation coordination system and method

A method for imaging an object includes radiating the object of interest and sensing the radiation that penetrates through the object using a detector having at least one active area and at least one inactive area, determining when the radiation is completed using information received from the inactive area of the imaging detector, and reconstructing an image of the object using information received from the active area of the imaging detector. A medical imaging system and a computer-readable medium are also provided.

System and method for monitoring X-rays received by a portable imaging detector

A digital detector of a digital imaging system is provided. In one embodiment, the digital detector includes a flat-panel detector having a detector array for converting X-ray radiation into image data. The digital detector may also include a plurality of antennas, and the digital detector may be configured to transmit the image data via one or more antennas of the plurality of antennas. Additional systems, methods, and devices are also disclosed.

Wireless digital image detector

Systems, methods and apparatus are provided through which in some embodiments, row-correlated noise of a digital X-ray detector is monitored during idle operation of the digital X-ray detector and the magnitude of the row-correlated noise is compared to a visible threshold.

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.
