Dual-Axis OCT Gets Under Skin

Facebook X LinkedIn Email
Optical coherence tomography (OCT), long considered the gold standard for imaging and diagnosing diseases of the eye, could be used to identify and evaluate conditions deep beneath the skin. A team led by Duke University’s Adam Wax has developed a method to increase the depth at which light can penetrate skin. The team adapted dual-axis OCT (DA-OCT) for this purpose and increased the imaging depth of conventional OCT by almost 50%, providing depth penetration in skin imaging at 1.3 µm. Though OCT can easily access the retina through the eye’s cornea and lens, it is...Read full article

    optical coherence tomography
    Optical coherence tomography (OCT) is a non-invasive imaging technique used in medical and scientific fields to capture high-resolution, cross-sectional images of biological tissues. It provides detailed, real-time, and three-dimensional visualization of tissue structures at the micrometer scale. OCT is particularly valuable in ophthalmology, cardiology, dermatology, and various other medical specialties. Here are the key features and components of optical coherence tomography: Principle of...
