    Area of Science:

    • Medical Imaging
    • Biomedical Engineering
    • Radiology

    Background:

    • Magnetic Resonance Imaging (MRI) is crucial for spinal diagnostics.
    • Current MRI coil technology can necessitate patient repositioning for different imaging needs.
    • Optimizing coil design can improve diagnostic workflow and image quality.

    Purpose of the Study:

    • To design and construct an adaptable overlapping surface coil assembly for spinal MRI.
    • To enable efficient switching between different coil sizes without patient repositioning.
    • To maintain or improve image quality during spinal MRI examinations.

    Main Methods:

    • Development of an overlapping surface coil assembly with integrated small and large coil elements.
    • Implementation of a switching mechanism allowing seamless transition between coil sizes.
    • Evaluation of image quality and diagnostic utility in spinal MRI applications.

    Main Results:

    • Successful design and construction of the overlapping surface coil assembly.
    • Demonstrated ability to switch between coil sizes without patient repositioning.
    • No degradation in image quality observed during screening and detailed spinal studies.

    Conclusions:

    • The developed overlapping surface coil assembly is effective for spinal MRI.
    • This coil design enhances imaging efficiency by eliminating the need for patient repositioning.
    • The system supports a streamlined workflow from initial screening to detailed diagnostic imaging.
