A 3D imaging and visualization workflow, using confocal microscopy and advanced image processing for brachyuran crab...

Area of Science:

• Zoology
• Microscopy
• Imaging Science

Background:

• Confocal laser scanning microscopy (CLSM) provides detailed morphological information for arthropods.
• Existing CLSM protocols lack standardized postprocessing for optimal image enhancement.
• Brachyuran crab zoeal stages are complex models for evaluating imaging techniques.

Purpose of the Study:

• To present a comprehensive CLSM protocol for arthropod visualization.
• To integrate micro-computed tomography (micro-CT) postprocessing techniques for improved image quality.
• To demonstrate the application of this protocol using brachyuran crab zoeal stages.

Main Methods:

• A multi-step protocol including sample cleaning, staining, digestion, and mounting.
• Confocal laser scanning microscopy data acquisition across multiple microscope brands (Leica, Nikon, Olympus, Zeiss).
• Image postprocessing using open-source software: ImageJ for data standardization and Drishti for surface rendering.

Main Results:

• The presented methodology successfully generated high-resolution, detailed 3D visualizations of arthropod morphology.
• Postprocessing techniques significantly improved image clarity and surface detail compared to standard CLSM.
• The protocol is robust and validated across different confocal microscope systems.

Conclusions:

• This protocol enhances the utility of CLSM for nondestructive arthropod morphological studies.
• Integration with micro-CT postprocessing offers superior image quality and data analysis potential.
• The open-source software approach ensures accessibility and reproducibility for researchers.
