    Area of Science:

    • Medical Imaging
    • Radiologic Technology

    Background:

    • Accurate alignment of the tomographic tube and cassette is crucial for image quality in conventional tomography.
    • Existing methods for assessing this alignment can be complex or time-consuming.

    Purpose of the Study:

    • To describe a simple, effective test object for assessing linear tomographic tube and cassette-movement alignment.
    • To provide a tool for quality assurance during the installation and performance testing of tomographic units.

    Main Methods:

    • The described test object features two offset pinholes.
    • One pinhole is positioned above the fulcrum plane, and the other is below it.
    • This configuration allows for visual assessment of alignment.
