    Area of Science:

    • Neuroscience
    • Computer Science
    • Image Reconstruction

    Background:

    • Accurate three-dimensional (3D) reconstruction of biological specimens is crucial for understanding complex structures.
    • Previous methods often required expensive hardware or complex software.
    • The need for accessible tools for detailed anatomical studies persists.

    Purpose of the Study:

    • To present a novel, low-cost software package for generating true perspective 3D reconstructions from serial sections.
    • To demonstrate the package's capability using a specific application in neuroanatomy.

    Main Methods:

    • Development of a software package for Apple II Plus computer.
    • Utilized a graphic tablet for data sampling and a menu-driven program for control.
    • Programs were initially written in BASIC and later translated to machine language for efficiency.
