The Power of Digital Pathology in Research

1. Leica Biosystems Proprietary Information. For Research Use Only. Not For Use in Diagnostic The Power of Digital Pathology In Research. Caitríona Lyons PhD.

2. Introduction • Caitríona Lyons PhD • Based in Dublin, Ireland • Current Role: • Product Manager Image Analysis, Leica Biosystems • Previous Roles: • Product Owner Image Analysis, Leica Biosystems • Image Analysis Specialist, Leica Biosystems • Education • BSc (Hons) Biomedical Science • PhD Medicine and Health • Postdoc Immunology

3. Agenda • History of Pathology • What is Digital Pathology • Power of Digital Pathology • Leica Biosystems Role in Digital Pathology • The Future of Digital Pathology • Final Thoughts 3 SCAN MANAGE ANALYZE

4. History of Digital Pathology • Pathology has been around for over 100 years • Telepathology has been around for nearly 50 years • Past decade: a true digital transformation has been happening • Whole slide imaging technology • Advances in software applications • Integration into different environments

5. What is Digital Pathology • Acquisition, management, sharing and interpretation of pathology information in a digital environment • High-resolution digital images are captured with a scanning device that can be viewed on a computer screen or mobile device • Both bright-field and fluorescent images can be captured

6.• Access to the right expertise on the right slide with the right tools • Efficient workflows • Remote access • Ability to view your images and data from anywhere • Freedom from the microscope • Quantitative Image Analysis at a level of detail impossible by eye • Maintain integrity of data • Searchable digital archive

7. • Tools to flag and help review complex or unusual slides / cases • Annotation of slides • Automatic micron measurement • Easy, accurate measurement of features • Number, color and intensity • View multiple slides side-by-side

8 • Maintains the integrity of the tissue on the slide • High to low throughput of glass slides • Walkaway scan protocol • Scans almost any brightfield or fluorescent stains • Supports 1x3 and 2x3 glass slide formats

9 • Images and data generated from the scanner can be meaningfully organized into specimens, cases and projects • Library of images generated from scanner is now: • Searchable • Accessible • Controllable

10 • Utilizes the managed images with image analysis applications to: • Identify cohorts of cells • Identify and score specific assays • Phenotype cells • Provides a permanent record of your results for every cell on a digital slide • Results that are: • Reproducible

11 • Identification of cohorts of cells, like infiltrating lymphocytes and tumor in breast H&E tissue • Identification and Scoring of specific assays, such as PD- L1 membrane stain in annotated regions of interest of lung tumor • Cell phenotyping, in this instance of cultured rat neurons based on antibody

12.

13 • Uses Machine Learning • Identification / Quantification of Disease vs Normal • Uses include oncology, toxicology, nephrology, injury & inflammation • Rapid / Consistent Annotation of Tissue(s) • Heterogeneous samples • Limited access to expert review • Validation or QC Aperio GENIE

14. Artificial Intelligence – AI John McCarthy in the 1955 proposal for the 1956 Dartmouth Conference “…every aspect of learning or any other feature of intelligence can in principle be so precisely described that a machine can be made to simulate it…” Machine Learning – ML Arthur Samuel, an IBM scientist, in 1959 “…field of study that gives computers the ability to learn without being explicitly programmed...” Deep Learning – DL 1965 – 1st deep learning model was developed by Alexey Grigoryevich Ivakhnenko and Valentin Grigorevich Lapa The Future of Digital Pathology: Artificial Intelligence

15. AI may provide the solution: • Aids in research • Automates assay(s) • Automates Image Analysis • Data is ready and available before the slide is open Range of H&E supported H&E Tumor mask from Prototype Cytokeratin – additional ground truth to exploit

16. Removes bias by allowing quantitative analysis Allows you to access your images from anywhere Consolidates your physical slides with digital images Provides a permanent archive of images The Future is Bright, The Future is Digital
