CT analysis for research, on your own computer.

Apollo does not upload your scans.

Images, metadata, and results are processed on your own computer, and exports are saved where you choose. There is no account, and license keys are checked without a network connection.

Apollo does need an internet connection to install a model and to download its weights the first time it runs. TotalSegmentator, which several analyses use, also reports each run to its authors by default, with details such as the task, platform, software versions, and a random installation ID, but nothing from the scan.

From a folder of DICOM to an exported table.

1. Import

   Add folders, ZIP archives, or individual files, and Apollo sorts the DICOM inside into studies and series.

2. Check

   Every series is quality-checked on import, with a plain explanation of each finding.

3. Choose the analyses

   Apollo shows which analyses can run on each series, and why the others cannot.

4. Run

   Queue one scan or a whole cohort; a scan that fails is flagged and the rest carry on.

5. Export

   Export the results to CSV, Excel, or JSON.

Published models, and measurements Apollo computes itself.

Apollo runs 18 analyses. Those from open-source projects are listed with their license and source. Coverage is deepest in the chest, and reaches head, abdomen, spine, and pelvis studies as well.

Each result notes how it was produced.

Every result records the model and its version, the quality-control status of its series, and the DICOM slices it was computed from.

What Apollo does not claim.

Apollo is research software. It is not FDA-cleared and does not produce management recommendations. Sybil’s attention overlays show where the model looked, not that a region is cancer. Density and attenuation values depend on the scanner and protocol, so compare them within a consistently acquired cohort. Checking models against their authors' reference outputs is work in progress, starting with Sybil.
