Background:

• Traditional 2D analysis of cell nuclei has limitations in accurately capturing complex morphology.
• Confocal laser scanning microscopy (CLSM) offers high-resolution optical sectioning capabilities.
• Quantitative analysis of nuclear features is crucial for disease diagnosis and understanding cellular processes.

Purpose of the Study:

• To develop and validate a 3D imaging method for cell nuclei acquisition and processing using CLSM.
• To enable accurate 3D visualization and quantitative analysis of cell nuclei.
• To differentiate between normal and abnormal cervical cell nuclei based on their 3D morphological features.

Main Methods:

• Employed contour-based surface rendering and volume rendering pipelines for 3D image reconstruction.
• Utilized a 3D labeling algorithm incorporating slice information for feature extraction.
• Quantified nuclear volume, surface area, and spherical shape factor for comparative analysis.

Main Results:

• Demonstrated statistically significant differences in 3D nuclear size between normal and abnormal cervical cells.
• The developed 3D method overcomes limitations of 2D analysis, enhancing quantification accuracy and reproducibility.
• Successfully extracted key 3D quantitative features of cell nuclei.

Conclusions:

• 3D visualization and quantification of cell nuclei provide critical medical information for objective diagnosis.
