• Hematology

Background:

• Accurate simulation of light scattering by biological particles like red blood cells is crucial for understanding optical properties of blood.
• Existing methods may be computationally intensive, limiting accessibility for researchers.
• Red blood cells (RBCs) are complex scatterers due to their size relative to visible light wavelengths.

Purpose of the Study:

• To develop a computational framework for rapid simulation of light scattering by multiple red blood cells.
• To provide an accessible approach for researchers using standard desktop computers.
• To validate the simulation framework against experimental data.

Main Methods:
