Whole Slide Tissue Image Library

for AI and Machine Learning Development

Accelerate AI-powered pathology research with access to high-quality whole slide images (WSI) linked to rich clinical, molecular, and outcomes data. Discovery’s WSI library enables the development of machine learning models for cancer detection, biomarker discovery, patient stratification, and treatment-response prediction. 

High-Resolution Images Paired with Comprehensive Metadata

Discovery’s WSI library is designed for AI and digital pathology applications, each dataset combines high-resolution tissue images with curated metadata to support robust model development and validation.

  • 40x H&E Whole Slide Images (WSI)
  • Scanned on the Aperio GT450 platform
  • ArtifactDetect™ image quality assessment
  • TumorDetect™ tumor content characterization
  • Pathology reports
  • Donor demographics
  • Additional clinical, biomarker, treatment and response information where available

ArtifactDetect and TumorDetect are research use only products available on PathAI’s AISight® Image Management System, not for use in diagnostic procedures.
