Two useful techniques in three-dimensional electron microscopy: quarter-micron serial sectioning and stereoscopy

N König, H Van der Loos

    Journal of Neuroscience Methods
    |February 1, 1980
    PubMed
    Summary

    Quarter-micron serial sectioning offers a practical middle ground for 3-D microscopy, providing sturdier, high-contrast images. This method requires fewer sections for reconstruction, improving efficiency in electron microscopic studies.

    Area of Science:

    • Microscopy
    • 3-D Imaging
    • Electron Microscopy

    Background:

    • Ultrathin sections are commonly used in electron microscopy.
    • Existing methods may not always require maximal electron microscope resolution.
    • 3-D analyses often demand higher resolution than light microscopy.

    Purpose of the Study:

    • To introduce and advocate for quarter-micron serial sectioning as an advantageous technique.
    • To highlight the benefits of quarter-micron sections over ultrathin sections in electron microscopy.

    Main Methods:

    • Serial sectioning at a quarter-micron thickness.
    • Utilizing light microscopy for analysis where electron microscopy resolution is not essential.

    Main Results:

    • Quarter-micron sections are sturdier and provide high-contrast images.
    • Each section contains more 3-D information, retrievable via stereoscopy.
    • Fewer sections are needed for 3-D reconstruction of tissue elements.

    Conclusions:

    • Quarter-micron serial sectioning is a valuable technique for 3-D analyses.
    • This method offers improved efficiency and image quality for specific electron microscopic applications.
    • It presents a practical alternative to ultrathin sectioning when maximal resolution is not required.
