Summary
Optical coherence tomography (OCT) provides high-resolution, real-time, in situ imaging of tissue structure. This optical biopsy technology offers a powerful alternative to traditional methods in medical diagnostics and interventional guidance.
Area of Science:
- Biomedical Engineering
- Medical Imaging
- Ophthalmology
Background:
- Optical coherence tomography (OCT) is an emerging high-resolution cross-sectional imaging technology.
- It functions analogously to ultrasound but utilizes light instead of sound waves.
- OCT provides micron-scale, real-time imaging of tissue structure in situ.
Purpose of the Study:
- To review the principles and technological advancements of OCT.
- To describe the potential biomedical and clinical applications of OCT.
- To highlight OCT's role as an optical biopsy and its advantages over conventional histopathology.
Main Methods:
- Review of existing OCT technology and literature.
- Discussion of OCT integration with catheters and endoscopes for intraluminal imaging.
- Exploration of OCT's capabilities for in situ and real-time tissue visualization.
Main Results:
- OCT enables high-resolution, micron-scale cross-sectional imaging of tissue.
- Combined with catheters/endoscopes, OCT facilitates intraluminal imaging of organ systems.
- OCT serves as an optical biopsy, providing real-time, in situ tissue assessment.
Conclusions:
- OCT is a powerful diagnostic imaging technology offering significant advantages over conventional methods.
- Its ability to image in situ and in real-time reduces risks associated with biopsies and aids interventional procedures.
- OCT holds substantial potential for diverse biomedical and clinical applications.
