    A new instrument creates high-quality medical image hard-copies using a computer-driven plotter and light source. This versatile system generates both monochrome and color prints from digital data, including nuclear magnetic resonance (NMR) images.

    Area of Science:

    • Medical Imaging
    • Biomedical Engineering
    • Computer Graphics

    Background:

    • High-quality hard-copy medical images are essential for diagnosis and research.
    • Existing methods for producing medical image hard-copies may have limitations in terms of quality, color reproduction, or versatility.
    • Digital imaging technologies generate vast amounts of data requiring effective visualization methods.

    Purpose of the Study:

    • To describe a novel and versatile instrument for producing high-quality monochrome and color hard-copy medical images.
    • To present examples of nuclear magnetic resonance (NMR) images produced by the system.
    • To introduce a refinement allowing the display of two variables within a single image.

    Main Methods:

    • Utilizes a computer-driven raster to scan a time-modulated light source over standard photographic print paper on an X-Y plotter.
