    Low-Cost, Portable System Takes OCT Beyond Ophthalmology

    esearchers have developed a way to perform optical coherence tomography (OCT) in hard-to-reach areas of the body such as joints. The advance could help bring this high-resolution biomedical imaging technique to new surgical and medical applications. OCT can image structures measured in microns, making it ideal for seeing subtle changes in tissue that might indicate disease or damage. Although OCT is now the standard of care in ophthalmology, making a high-quality OCT instrument compact enough for use inside the body has been challenging. In The Optical Society (OSA) journal Optics Letters, researchers from Duke University report how they used a ...

    1. We saw a need for OCT image guidance in arthroscopic surgery, a minimally invasive procedure that uses an endoscope to address joint damage.
    2. By developing a new portable, low-cost version of OCT, we show that the success of this imaging approach will no longer be limited to ophthalmology applications.
