    Area of Science:

    • Ophthalmology
    • Biomedical Optics
    • Medical Imaging

    Background:

    • High-quality swept-source optical coherence tomography (SS-OCT) and optical coherence tomography angiography (OCTA) depend on precise k-sampling.
    • Current hardware-driven k-sampling methods in SS-OCT systems present challenges related to cost, alignment, imaging depth, and clocking stability.

    Purpose of the Study:

    • To introduce and validate an optimized numerical k-sampling method as a cost-effective alternative to hardware k-clock systems.
    • To demonstrate the capability of numerical k-sampling for high-resolution and deep-tissue imaging in SS-OCT and OCTA.

    Main Methods:

    • Developed and implemented an optimized numerical k-sampling algorithm to process SS-OCT data.
    • Evaluated the axial resolution, signal roll-off, and imaging depth achieved with the numerical method.
    • Applied the method to structural OCT and OCTA imaging of macular and deeper ocular tissues.

    Main Results:

    • Achieved high axial resolution (4.9-µm FWHM in air) and low signal roll-off (2.3 dB loss) over a 4-mm imaging depth.
    • Demonstrated the ability to visualize fine anatomic and microvascular structures, including the lamina cribrosa.
    • Confirmed the effectiveness of the numerical method for both structural OCT and OCTA.

    Conclusions:

    • The optimized numerical k-sampling method offers a viable, hardware-free solution for high-quality SS-OCT and OCTA.
    • This technique facilitates detailed imaging of ocular structures, beneficial for diagnosing retinopathy and optic neuropathy.
