    A modified chin holder, adapted from an electroencephalography chair, effectively reduces head movement during CT scans. This innovation minimizes motion artifacts, improving computed tomography image quality.

    Area of Science:

    • Medical Imaging
    • Biomedical Engineering

    Background:

    • Head movement is a common source of artifacts in computed tomography (CT) imaging.
    • Motion artifacts degrade image quality and can obscure diagnostic details.

    Purpose of the Study:

    • To describe a modified chin holder for reducing head movement during CT scans.
    • To evaluate the effectiveness of the device in minimizing motion artifacts.

    Main Methods:

    • Modification of a commercially available electroencephalography chair to create a chin holder.
    • Utilizing the modified chin holder in computed tomography examinations.

    Main Results:

    • The modified chin holder significantly decreased patient head movement.
    • Resultant motion artifacts during computed tomography were substantially reduced.

    Conclusions:

    • The described chin holder is an effective tool for minimizing head motion in CT imaging.
    • This device can improve the diagnostic accuracy of CT scans by reducing motion-related artifacts.
