OCT Images Blood Vessels that Feed Cancer

Facebook X LinkedIn Email
VIENNA and MUNICH, Oct. 9, 2012 — An optical coherence tomography (OCT) technique that noninvasively maps the network of tiny blood vessels in the epidermis could soon help doctors better diagnose, monitor and treat skin cancer. Scientists at Medical University Vienna (MUW) are the first to use the high-resolution three-dimensional imaging method to visualize the network of blood vessels beneath the outer layer of the skin — the epidermis — that feed cancerous lesions. A laser light source developed at Ludwig Maximilian University was used to maximize image quality. It also enabled unprecedented high-speed...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...
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
