An x-ray grid alignment circuit for coupling an x-ray grid to a detector includes a marker configured to be mounted to the x-ray grid, a sensor configured to be mounted to the detector, the sensor generating an alignment signal based on a position of the marker, and an alignment module configured to receive the alignment signal from the sensor and utilize the alignment signal to determine if the x-ray grid is coupled to a detecting face of the detector. A detector assembly including the x-ray grid alignment circuit and a method of coupling an x-ray grid to a detector are also provided.
