Axial resolution is a critical factor in determining the quality of OCT images. It defines the system’s capability to distinguish between structures along the depth or axial direction. With resolutions reaching the micrometer range, OCT systems are adept at providing intricate visualizations of tissue layers and microstructures.

The system emits light, usually in the near-infrared spectrum, which is then divided into optical and reference beams. The optical beam interacts with the tissue, creating interference patterns. These patterns are processed to reconstruct detailed cross-sectional images of the tissue.

TD-OCT employs a moving reference mirror to enable depth scanning, while SD-OCT uses a spectrometer to enable simultaneous depth information capture, therefore improving signal-to-noise ratios and imaging speeds.

The addition of Optical Coherence Tomography Angiography (OCTA) has further enhanced the precision and informativeness of blood vessel imaging. This article explores the key components and capabilities of OCT systems, their diverse applications, and their significant impact on diagnosing and managing diseases such as age-related macular degeneration (AMD) and macular edema.

By analyzing changes in the OCT signal over time, it is possible to create detailed maps of the vascular network, which are key to performing perfusion evaluations and identifying vascular abnormalities.
