Visilab Viewer offers a standardized solution for whole slide image (WSI) viewing, enabling interoperability and efficient navigation of digital pathology slides. This DICOM-compliant platform enhances usability and data exchange in anatomical pathology.
Area of Science:
- Digital Pathology
- Medical Imaging Informatics
- Computational Pathology
Background:
- Increasing adoption of digital scanners in anatomical pathology.
- Lack of standardized whole slide image (WSI) format necessitates interoperability.
- Need for shareable and computable clinical information in pathology.
Purpose of the Study:
- To describe Visilab Viewer, a robust solution for interacting with WSIs.
- To ensure compatibility with any WSI based on the Digital Imaging and Communications in Medicine (DICOM) standard.
- To provide a platform for shareable and computable clinical information.
Main Methods:
- Development of Visilab Viewer, a web platform integrated with a DICOM-compliant web architecture.
- Implementation of specific modules for DICOM pyramid structure information and browser cache aggregation.
- Testing and comparison with three existing web viewers using 10 WSIs.
Main Results:
- Visilab Viewer demonstrated superior performance in quantitative (load time, frame loading) and qualitative (speed, usability) assessments.
- Achieved successful interoperability testing at the 2nd worldwide DICOM Connectathon with multiple scanner vendors.
- The architecture facilitated fast and fluid navigation over tissue slides.
Conclusions:
- Visilab Viewer provides unrestricted navigation and visualization of pathology samples.
- The platform enhances fluidity and usability through optimized slide display modules.
- Visilab Viewer successfully exchanges DICOM data, validated by Connectathon participation.
