OCT (Optical Coherence Tomography) is a non-invasive optical imaging technique that uses low-coherence interferometry to provide cross-sectional images of tissue microstructure with 1-15 micrometer resolution. It was developed in 1991 by Huang et al.

What is OCT?

• Non-invasive optical imaging technique
• Uses low-coherence interferometry
• Provides cross-sectional tissue microstructure images
• Achieves 1-15 micrometer resolution
• Developed in 1991 by Huang et al.

OCT works by using a broadband light source that emits light, which is then split into reference and sample arms. The sample arm reflects off tissue layers, and the resulting interference pattern generates depth-resolved images.

How OCT Works

The slide compares two types of OCT images: Time-domain OCT (TD-OCT), which uses traditional time-of-flight measurements but has slower speeds limiting resolution and suitability for early diagnostics, and Spectral-domain OCT (SD-OCT), an advanced Fourier-domain method offering faster scanning, higher sensitivity, and detailed visualization of retina layers and coronary arteries for modern clinical use. SD-OCT is preferred due to its improved speed and image quality over TD-OCT.

Types of OCT Images

The slide highlights key medical applications of OCT technology, with 70% accuracy in retinal disease diagnosis for ophthalmology and 50% improvement in stent visualization for cardiology. It also notes over 10 million annual OCT scans worldwide and non-invasive skin cancer detection as a dermatology breakthrough.
