Research use only

This is a research demonstration and is not a medical device. It has not been validated or approved for clinical use, and it must not be used for diagnosis, treatment or any other clinical decision. Scores can be wrong. RADAR ships no calibrated thresholds; scores of 50% or more are shown as positive for display only.

Files you choose are read and processed inside this browser tab, using your GPU or CPU. No image data or results are uploaded anywhere. The only downloads are this page and the model files (~116 MB from Hugging Face), which are fetched once and cached in the browser. After the first visit the page also works with the internet turned off.

What you need

  • Browser: a recent desktop Chrome or Edge (tested). Firefox and Safari may work in CPU mode but are untested. Phones and tablets are not supported.
  • Memory: 8 GB RAM minimum, 16 GB recommended. The tab peaks at about 4 GB during a run.
  • CPU: any 64-bit CPU. A run takes about 35 s on a 16-core desktop; expect a few minutes on a 4-core laptop.
  • GPU (optional): WebGPU mode needs about 8 GB of free GPU memory and takes about 5 s on a desktop GPU. If it fails, Auto mode falls back to the CPU.
  • Storage and network: about 150 MB of browser storage, and an internet connection for the first visit only.

Drop a CT here: a zip of a DICOM study, a DICOM folder, loose DICOM files, or a .nii / .nii.gz volume.

From a study, the largest axial CT series with "abd" in its description or body part is used; otherwise the largest CT series. Only that series' slices are read.
