1. A method for rendering volume radiographic image content of a subject, the method executed at least in part on a computer and comprising:

  • forming a volume image by processing a plurality of 2-D projection images of the subject, the volume image having Hounsfield values;

    extracting a first image slice from the volume image;

    modifying the extracted first image slice from the volume image by;

    (i) defining two or more spatial frequency bands from first image slice data; and

    (ii) applying one or more viewer adjustments to the first image slice data, wherein the one or more viewer adjustments condition the image data to enhance image content in at least one of the defined two or more spatial frequency bands;

    generating a set of one or more display rendering parameters according to the two or more frequency bands and according to viewer adjustments made to the first image slice;

    extracting a second image slice from the volume image, the second image slice having Hounsfield values;

    applying the generated set of display rendering parameters to the second image slice obtained from the volume image to render an adjusted image slice; and

    preserving the Hounsfield values of the second image slice by corresponding the Hounsfield values of the second image slice with the adjusted image slice;

    displaying, storing, or transmitting the adjusted image slice; and

    in response to a user request, displaying at least one of the preserved corresponding Hounsfield values.
