Digital Pathology AI Services
Precision Annotation for Pathology AI That Saves Lives
Looking for reliable Digital Pathology AI services, including WSI annotation, tissue segmentation, cell detection, and tumour grading across the UK, US, Europe, and Africa? Aya Data delivers precise pathology AI data to help industry leaders move models from pilot to production. Achieve your AI goals with us!
Expert Pathology AI Annotation
Digital pathology is transforming how cancer is diagnosed, how drugs are discovered, and how rare diseases are understood. But the AI models driving this revolution are only as good as their training data. Aya Data combines board−certified pathologists, specialist annotators, and rigorous quality control to deliver the precise, clinically validated labels your models need at scale, on time, and fully compliant with HIPAA, GDPR and ISO 9001.

Digital Pathology AI Services for Your Business
Whether you need expert annotation, hard−to−source pathology datasets, or a fully deployed AI model, we cover every stage of your pathology AI journey.
Whole Slide Image (WSI) Annotation
- Our pathologist−supervised annotation teams deliver pixel−precise labels across the full spectrum of digital pathology use cases: from coarse tissue−type segmentation to fine−grained cellular classification at scale.
- Tissue region segmentation (tumour, stroma, necrosis, normal)
- Tumour micro−environment mapping
- Polygon, bounding box, and semantic segmentation mask creation
- Cell−level detection and classification (mitosis, apoptosis, immune cells)
- Multi−stain annotation (H&E, IHC, FISH, PAS, Masson’s trichrome)
- DICOM−compatible output and format conversion
- Consensus review and inter−annotator agreement scoring
Pathology Data Acquisition
Sourcing high−quality pathology data is one of the hardest challenges in building medical AI. Our global network of hospital and research partners enables us to source, de−identify and deliver rare pathology datasets that are almost impossible to find elsewhere.
- Whole slide image sourcing across multiple tissue types and indications
- Multi−centre cohort datasets with clinical metadata
- HIPAA & GDPR−compliant de−identification pipelines
- Rare disease and paediatric pathology collections
- Synthetic data augmentation for class imbalance
- IRB and ethics documentation support
- Secure data transfer and storage on compliant cloud infrastructure

OUR NETWORK
Leverage Aya Data’s Healthcare Pathology Network
Building high−quality Pathology AI requires deep medical expertise. That’s why we work closely with leading pathologists and healthcare institutions to guide our annotation workflows, validate outputs, and ensure every pathology dataset meets the highest standards of clinical accuracy.
Data Annotation for Every Pathology Use Case
Our annotators use advanced tools QuPath, ASAP, PathML, V7 Darwin to deliver precise, clinically validated labels across the full breadth of digital pathology applications.
Tissue Region Segmentation
Accurate delineation of tissue regions is the foundational step for most pathology AI tasks. Our annotators label tumour, stroma, necrosis, fat, muscle, and normal tissue with pixel−level precision−providing the spatial context your models need to reason about a disease.
Cell Detection & Classification
Our specialist annotators label mitotic figures, tumour−infiltrating lymphocytes (TILs), apoptotic bodies, macrophages, neutrophils and other cell populations with high inter−annotator agreement (typically >0.92 Cohen’s κ).
Tumour Grading & Staging
Tumour grading requires a pathologist−level understanding of histological patterns. Our teams include clinically trained annotators who can apply established grading systems−Gleason for prostate, Nottingham for breast, Clark/Breslow for melanoma−to produce clinically meaningful training labels.
Biomarker & Spatial Analysis
Biomarker scoring is critical for immuno−oncology, companion diagnostics and precision medicine. Our annotators and AI−assisted scoring tools can produce validated labels for a wide range of prognostic and predictive biomarkers used in clinical trials and drug development.
IHC & Multi−Plex Quantification
Immunohistochemistry and multi−plex immunofluorescence unlock spatially resolved protein expression data that is increasingly critical in immuno−oncology and autoimmunity research.
