1. A method of improving the consistency of coronary calcium scoring, the method comprising:

  • imaging a phantom with an imaging device to produce an image of the phantom;

    measuring a spatial resolution from the image of the phantom;

    comparing the measured spatial resolution of the image of the phantom against a reference spatial resolution;

    choosing a filter algorithm, wherein when filter is applied to the phantom image a filtered image is produced having a spatial resolution substantially matching the reference spatial resolution;

    subsequent to choosing a filter algorithm, obtaining an image of a subject;

    applying the filter algorithm to the image of the subject to create a filtered image that has a spatial resolution that substantially matches the reference spatial resolution; and

    computing a coronary calcium score from the filtered image.
