    Abstract: A gain correction and calibration technique for digital imaging systems is provided. In one embodiment, a method may include acquiring a plurality of dark images via a digital detector of an X-ray system. Acquiring the plurality of dark images may include acquiring data from a plurality of data channels of the digital detector during an analog test mode of the digital detector in which calibration voltages are applied to the data channels. The method may also include calibrating a channel gain map of the detector based on the plurality of dark images. Additional systems, methods, and devices are also disclosed.

    Abstract: Systems and methods are provided for managing power consumption of a medical imaging detector by the use of triggering signals, environmental condition data, and/or determination of a variable time interval triggering event that is unique for each power consumption state. Systems and methods are provided for managing power and temperature of a device, after receiving a request for a function to be performed by the device determining an “on” trigger component, an “off” trigger component, associated circuits for performing the received function, providing power to the associated circuits upon the occurrence of the “on” trigger component, and removing power to the associated circuits upon the occurrence of the “off” trigger component. Further, an instruction is described for determining and displaying a variable time interval that is indicative of a time to change from one state to a desired state.

    Abstract: Systems and methods are provided for offset correction of images from a flat panel detector. In some embodiments, the apparatus and method develops one or more offset maps, acquired during system idle, for the imaging system at a plurality of exposure windows. In some embodiments, exposure parameters acquired for the imaging system before image acquisition are used to select an offset map to subtract from subsequent X-ray images. In some further embodiments, executable instructions are disclosed for directing a processor to compile one or more offset map and exposure parameters to subtract based on a selected offset map noise elements from X-ray images and thereby minimizing the time between image acquisition and display of processed images.
