Gradient Health has announced the release of Atlas 2, an upgrade to its self-service medical imaging data platform used by AI developers worldwide.
The new version introduces deeper search capabilities, a redesigned developer experience and improved collaboration tools to streamline the process of building representative imaging datasets.
Atlas 2 provides immediate access to more than 20 million imaging studies, with a further 30 million in progress or contracting.
The platform now supports hundreds of DICOM tags, rich series-level metadata and longitudinal patient-level search, giving developers a level of visibility and precision that previously required significant manual effort or custom pipelines.
Searchability
Atlas 2 expands the depth of search with more metadata, more structure and more context. Developers can filter across hundreds of DICOM tags, explore series-level information and review patient-level histories. These capabilities make it easier to define cohorts that reflect real clinical scenarios and avoid blind spots that can limit model performance.
Usability
Atlas 2 introduces a faster and more intuitive interface designed to reduce friction at every stage of dataset creation. Navigation is simpler, cohort building is quicker and the overall workflow allows users to move from search to export with fewer steps. The platform is built for developers who need rapid access to imaging data at scale without compromising on quality.
Collaboration
Teams can now work together more effectively with shared cohorts, common workspaces and improved dataset analytics. Atlas 2 supports visibility across projects and allows groups to review, refine and manage datasets in a consistent way. This helps organizations maintain quality and accelerate development across multiple projects.
Josh Miller, CEO of Gradient, says: “The future of medical AI will be driven by developers who can access high quality imaging data quickly and responsibly, whether they are training targeted clinical tools or building large foundation models.
“Atlas 2 gives them that foundation. We designed it to remove friction, improve clarity, and support progress that improves outcomes for entire populations, not just those who are already well served.”
Atlas 2 is available immediately. Gradient will feature daily sessions throughout RSNA 2025 for attendees who want a guided look at the new capabilities. Developers not in Chicago can get started today with a free 7 day trial.
