Learn how Novartis leverages HALO’s GraphQL API to streamline oncology pipelines


HALO/HALO Link offer a comprehensive set of image viewing, analysis and display tools. However, linking HALO results to external tools such as legacy LIMS software and emerging image analysis and AI frameworks has been challenging. The emergence of Indica Labs’ GraphQL API has allowed our group to, for the first time, connect our HALO Link system to critical internal tools such as our heavily-customized eSlide Manager (outside of the 3rd party integration offered by Indica). In addition, we can now enable bidirectional integration of custom Python analyses focused on both image analysis and machine learning solutions for complex pathology-based projects. This presentation will illustrate a suite of tools developed by our group utilizing the GraphQL framework to streamline existing workflows within Novartis and begin to integrate pathology-based tools from across the organization into the HALO environment.

Learning Objectives

  • Learn how Novartis connected HALO Link to a heavily-customized eSlide Manager  
  • Discover how Novartis is using integrated Python scripts for image analysis and machine learning
  • See how Novartis is using the GraphQL framework to streamline existing workflows
