Prosthetic Valve Voltage Effect on Blood Cell and Protein Deposit Areas from SEM Imaging

5.5 KB Excel dataset from figshare, uploaded by Lokeswara Rao Sajja and last updated on 2026-05-06. It quantifies the effect of electrical voltage on the deposition of red blood cells, platelets, and acellular protein coagulum on prosthetic valves using scanning electron microscopy (SEM). The data provides absolute and relative area measurements for these deposits aggregated across images for each voltage condition.

Use Cases

• Modeling the relationship between applied voltage and deposit area based on the aggregated area measurements.
• Comparing the relative adhesion of red blood cells, platelets, and acellular protein under different electrical conditions.
• Analyzing the distribution of deposit-free zones versus covered areas on the valve surface.
• Validating in-vitro test protocols for prosthetic valve materials using quantitative SEM image analysis.

Strengths

• Data is openly licensed under CC-BY-4.0.
• Provides quantitative area measurements (μm²) and relative percentages for three deposit types.
• Aggregates measurements across multiple SEM images per experimental condition.

Limitations

• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The 5.5 KB file size indicates a very small dataset with limited scope.
• Description metadata is limited; actual data quality and experimental details require verification.
