    Area of Science:

    • Medical Imaging
    • Nuclear Medicine
    • Computer Graphics

    Background:

    • Tomographic images in nuclear medicine typically display 2D slices.
    • Visualizing 3D radionuclide distributions from these slices is challenging.

    Purpose of the Study:

    • To develop a method for direct perception of 3D radionuclide distribution morphology.
    • To improve the visualization of three-dimensional activity in nuclear medicine.

    Main Methods:

    • Utilized computer graphics to generate shaded surface images from tomographic data.
    • Developed a smooth shading algorithm based on local polynomial fitting for coarse spatial sampling.
    • Implemented a solid model approach for interactive data storage and viewing from any aspect.

    Main Results:

    • Successfully applied the technique to radionuclide tomograms of various organs.
    • Demonstrated the ability to perceive 3D morphology directly from iso-count surfaces.
    • The method allows interactive viewing of reconstructed activity distributions.

    Conclusions:

    • The iso-count surface display technique offers direct 3D perception of radionuclide distributions.
    • This visualization method is particularly promising for cardiac blood pool imaging.
    • The developed algorithm effectively handles the spatial limitations of radionuclide tomograms.
