Open Resources for Advanced Imaging Research

CAI2R provides MRI data, tools for clinical translation, image reconstruction code, RF simulation tools, and image analysis software.

We also offer RF hardware.

To enable and encourage innovation throughout the field of biomedical imaging, we openly share advanced research resources. Many resources can be downloaded through this website; Some are hosted on dedicated micro-sites or maintained on version-controlled repositories, such as Github.

  • Raw k-space data and DICOM images from thousands of MRI scans of the knee, brain, and prostate, curated for machine learning research on image reconstruction.

  • Reproducibility data for two seminal machine learning MR image reconstruction studies.

  • Simultaneously acquired positron emission tomography and magnetic resonance data of the brain, plus joint image reconstruction code.

  • MRI data from suspensions of spherical polystyrene microbeads for research on gradient-echo and spin-echo signal decay in the presence of microstructural sources of magnetic susceptibility.
