1. An x-ray laminography imaging system that utilizes a stationary x-ray source and generates a moving pattern of x-ray spots on a target anode synchronously with rotation of an x-ray detector to reduce or eliminate the need to move an object being imaged, the system comprising:

  • first logic configured to gather empirical calibration data generated during physical calibration of the system during which a stationary x-ray source generates a moving pattern of x-ray spots on a target anode synchronously with rotation of an x-ray detector, the empirical data corresponding to offsets to locations at which the x-ray spots are formed on the target anode;

    second logic configured to analytically derive calibration data from the empirical data; and

    third logic configured to calibrate the system using the empirical data and the analytically-derived calibration data.
