HTT update 20210930

All Updates

30 September 2021 Update

We are pleased to announce some recent accomplishments of the High-throughput truthing project (HTT).

The HTT project’s objective is to create a validation dataset fit for a regulatory purpose. Pursuing this objective is expected to inform regulatory frameworks and be instructive to others to develop their own validation datasets. For more detailed information about the project and/or to register as a pathologist-data-collector, please visit

Current and upcoming activities

10 Sept-1 Oct: Joint TILs Annotation and Discussion Sessions with Pathologists

  • Dr. Victor Garcia and Dr. Brandon Gallas are leading discussions to identify critical instructions for our annotation trainings that will lead to less pathologist variability (generally) and improve our future validation dataset (specifically).
  • We’d be happy to circulate summaries of the discussions and the feedback we will give to pathologists.
  • We plan to present the results at Pathology Informatics and in a publication.
