Multimodal Raman spectroscopy and optical coherence tomography for biomedical analysis

Area of Science:

• Biomedical Optics
• Medical Imaging
• Spectroscopy

Background:

• Optical techniques offer fast, non-invasive disease detection.
• Raman spectroscopy (RS) quantifies biomolecular content but lacks morphological data.
• Optical Coherence Tomography (OCT) provides morphology but lacks molecular contrast.

Purpose of the Study:

• To review the integration of RS and OCT for enhanced biomedical analysis.
• To highlight the benefits of combining structural and biochemical tissue interrogation.
• To discuss design considerations and data interpretation for combined RS-OCT systems.

Main Methods:

• Review of existing literature on combined RS-OCT instrumentation.
• Analysis of design principles for multimodal optical systems.
• Exploration of data interpretation strategies for integrated spectral and structural imaging.

Main Results:

• Integrated RS-OCT systems enable simultaneous structural and biochemical tissue analysis.
• Multimodal approaches overcome limitations of individual techniques.
• Combined systems offer a more comprehensive toolkit for clinical diagnosis.

Conclusions:

• Integrating RS and OCT into a single instrument significantly enhances diagnostic capabilities.
• This multimodal approach provides a more complete picture of tissue health.
• Further development in RS-OCT holds promise for advanced clinical applications.
