Characterization Method for 3D Substructure of Nuclear Cell Based on Orthogonal Phase Images

Area of Science:

• Biophysics
• Optical microscopy
• Cell biology

Background:

• Optical models of blood cells are essential for understanding cellular behavior.
• Phase imaging techniques reveal detailed cellular structures based on refractive index variations.

Purpose of the Study:

• To introduce optical models of blood cells with symmetrical components.
• To develop a method for characterizing cell morphology and substructure using phase imaging and inflexion curves.

Main Methods:

• Simulating wrapped and unwrapped phase images from orthogonal directions of optical cell models.
• Analyzing phase mutation at cellular boundaries (nucleus-cytoplasm, cytoplasm-environment).
• Introducing and applying the inflexion curve equation to model cell features.

Main Results:

• Orthogonal phase images successfully captured phase mutations at cell boundaries.
• The inflexion curve analysis effectively described the size, morphology, and substructure of a mononuclear cell model.
• Simulation results validated the method's ability to characterize cellular substructures.

Conclusions:

• The inflexion curve method, based on orthogonal phase images, provides an effective way to describe cell substructures.
• This approach offers a potential new method for rapid identification of biological cells without scanning.
