    Area of Science:

    • Ophthalmology
    • Nuclear Medicine
    • Medical Imaging

    Background:

    • Radionuclide studies of the lacrimal system require precise patient positioning.
    • Inadequate immobilization can lead to motion artifacts, compromising image quality and diagnostic interpretation.
    • Existing methods for patient stabilization may be suboptimal for detailed lacrimal system assessment.

    Purpose of the Study:

    • To describe a head-holder designed for effective patient immobilization during lacrimal system radionuclide studies.
    • To highlight the importance of immobilization for achieving diagnostic-quality imaging in this specific application.

    Main Methods:

    • Development and implementation of an adjustable head-holder.
    • The head-holder allows for both vertical and horizontal adjustments to accommodate patient anatomy.
    • Utilized in conjunction with standard radionuclide imaging protocols for the lacrimal system.

    Main Results:

    • The adjustable head-holder effectively immobilizes patients during lacrimal system radionuclide studies.
    • Consistent immobilization leads to improved image quality, reducing motion-related artifacts.
    • Facilitates clearer visualization of lacrimal gland and duct function.

    Conclusions:

    • Proper patient immobilization is critical for successful lacrimal system radionuclide imaging.
    • The described adjustable head-holder is a valuable tool for enhancing image quality and diagnostic accuracy.
    • This technique supports more reliable evaluation of lacrimal system disorders.
