Some embodiments include an x-ray detector, comprising a housing; a sensor array disposed in the housing and configured to generate image data in response to incident x-rays; a control logic disposed in the housing; a connector interface integrated with the housing; and an adapter removably couplable to the connector interface; wherein: the control logic is configurable to operate in a plurality of operating modes; and for a first operating mode of the operating modes, the control logic is configured to process the image data and/or transmit the image data through the adapter differently than for a second operating mode of the operating modes.

Modular x-ray detectors and systems

Some embodiments include a system, comprising: a plurality of pixels; a plurality of data lines coupled to the pixels; a plurality of switches coupling the pixels to the data lines; a plurality of readout circuits coupled to the data lines; control logic coupled to the readout circuits, the control logic configured to, for one of the pixels: acquire a first value for the pixel while the corresponding switch is in an off state; reset the corresponding readout circuit corresponding for the pixel; acquire a second value for the pixel after resetting the readout circuit; turn on the corresponding switch; acquire a third value for the pixel after turning on the corresponding switch; and combine the first value, the second value, and the third value into a combined value for the pixel.

Pixel noise cancellation system

Some embodiments include a method, comprising: integrating an input signal using an integrator to generate an integrated signal; comparing the integrated signal to a threshold; and injecting an offset signal into the integrator in response to comparing the integrated signal to the threshold such that the integrated signal passes the threshold.
