Summary
This study developed an automated high-resolution whole slide imaging system for digital pathology. The system digitizes both brightfield and fluorescence microscopy slides, enhancing collaboration and sample preservation in pathology.
Area of Science:
- Anatomic Pathology
- Biomedical Imaging
- Digital Pathology
Background:
- The last decade has seen significant advancements in anatomic pathology, driven by the need for safer and more collaborative diagnostic methods.
- Virtual microscopy (VM) systems offer automated digitization of microscopic samples, reducing physical handling risks and improving sample distribution.
- Existing VM systems face challenges in high-resolution digital imaging for pathology.
Purpose of the Study:
- To describe the development of an automated high-resolution whole slide imaging (WSI) system for digital pathology.
- To address hardware and software challenges in digitizing pathology samples.
- To enable both brightfield and fluorescence microscopy digitization.
Main Methods:
- Developed an automated WSI system incorporating both color and monochrome cameras with LED illumination.
- Integrated hardware control with acquisition software for full sample digitization.
- Quantified digital image quality using sharpness, contrast, and focus metrics.
Main Results:
- The system successfully digitized 150 tissue samples (brain, prostate, lung) across five magnifications (2.5× to 63×).
- Achieved high-resolution images for both brightfield and fluorescence microscopy.
- Image quality was validated using objective metrics.
Conclusions:
- The developed WSI system provides a robust solution for high-resolution digital pathology image acquisition.
- The system enhances collaboration and sample preservation through digital slide creation.
- This technology has the potential to significantly impact diagnostic workflows in anatomic pathology.
