A computer controlled system for multiple site microcirculatory measurements

Area of Science:

• Biomedical Engineering
• Microscopy Techniques
• In Vivo Imaging

Background:

• Intravital microscopy requires precise spatial data acquisition.
• Studying tissue heterogeneity and vascular architecture is crucial for understanding physiological and pathological processes.
• Current methods may lack the speed and accuracy for dynamic in vivo studies.

Purpose of the Study:

• To develop and validate a novel system for automated intravital microscopy.
• To enable high-resolution spatial mapping of optical signals within living tissues.
• To apply the system for analyzing tissue metabolism and vascular network topology.

Main Methods:

• Development of a computer-controlled motor-driven microscope stage.
• Integration of optical signal recording with X-Y (and Z) coordinate acquisition.
• Automated, repetitive movement between selected tissue sites for data collection.

Main Results:

• The system successfully records optical signals and precise spatial coordinates (X-Y, Z) up to 100 cm2.
• Demonstrated capability for rapid, repetitive site-to-site measurements.
• Successful mapping of topological features, tissue metabolism heterogeneity, and vascular network architecture.

Conclusions:

• The developed system significantly enhances intravital microscopy capabilities.
• It allows for detailed spatial and temporal analysis of biological processes in vivo.
• This technology provides a powerful tool for research in tissue metabolism and vascular biology.
