Optical coherence tomography (OCT) provides high-resolution subsurface imaging using infrared light. This advanced diagnostic tool is increasingly used in clinical practice, particularly for the gastrointestinal tract and pancreaticobiliary system.
Area of Science:
- Biomedical Optics
- Medical Imaging Technology
Background:
- Optical coherence tomography (OCT) is a non-invasive imaging technique established in 1991.
- It utilizes infrared light to visualize subsurface microstructures in biological tissues.
- Challenges in optical imaging include light scattering and absorption by living tissues.
Purpose of the Study:
- To highlight the evolution and clinical applications of OCT.
- To discuss OCT's utility in imaging complex biological systems.
Main Methods:
- OCT employs backscattered or backreflected infrared light.
- It achieves high-resolution, cross-sectional, subsurface tomographic imaging.
- Analysis focuses on the feasibility and effectiveness of OCT in biomedical contexts.
Main Results:
- OCT technology has transitioned from a laboratory tool to a clinical diagnostic modality.
- Significant advancements have expanded its applications in recent years.
- Successful implementation in imaging the gastrointestinal tract and pancreaticobiliary system is noted.
Conclusions:
- OCT is a powerful imaging modality with growing clinical significance.
- Its ability to image microstructures non-invasively makes it valuable for diagnostics.
- Further applications in medicine are anticipated, especially in challenging biological environments.
