Step‑by‑step: How digital pathology works
To appreciate these innovations, it helps to understand a typical digital pathology workflow, which illustrates how automation and AI integrate with microscopy:
- Sample preparation and staining. A tissue biopsy is fixed, embedded in paraffin, sectioned into thin slices and stained (e.g., hematoxylin–eosin). Proper fixation preserves cellular morphology and antigenicity.
- Slide scanning. The glass slide is loaded onto a whole‑slide scanner, which moves the stage in a grid pattern. High‑resolution objective lenses capture overlapping images of each field. The scanner stitches these images together into a single gigapixel‑scale digital slide. Advanced scanners correct for focus automatically and adjust illumination to ensure uniform brightness across the slide.
- Image storage and viewing. The digital slide is saved in a secure database and compressed for efficient transmission. Pathologists access the slide via a web viewer or dedicated software, where they can zoom, annotate, and measure structures. Integration with laboratory information systems ensures patient metadata accompanies the images.
- AI‑assisted analysis. Deep‑learning algorithms analyze the slide for specific features—such as mitotic counts, tumor infiltrating lymphocytes or biomarker expression. AI highlights suspicious regions, quantifies percentages of positive cells and generates preliminary reports. In some systems, AI triage orders the slide queue so that the most urgent cases are reviewed firstpmc.ncbi.nlm.nih.gov.
- Remote consultation and reporting. Because slides are digital, pathologists can share them instantly with colleagues worldwide. Subspecialists review the images remotely, discuss findings via teleconferencing and finalize the diagnosis. Reports and annotations are stored alongside the images for quality assurance and education.
Digital pathology not only speeds diagnosis but also creates a dataset for research. Machine‑learning models require large numbers of annotated images; digital archives of slides paired with clinical outcomes enable the development of prognostic models and biomarker discovery.
