1. A medical imaging system comprising:

  • an x-ray source for generating x-rays;

    calibration markers positioned in a path of the x-rays;

    an x-ray receiving device for receiving the generated x-rays and deriving a digital image representing objects through which the generated x-rays have passed, the digital image including representations of the calibration markers; and

    a processor coupled to the x-ray receiving device for performing image processing operations on the digital image, the image processing operations modifying the visual presence of the representations of the calibration markers, based on characteristics of an image area surrounding the calibration markers.
