DICOM to MinIO

Script to upload directories of DICOM files to MinIO.

Requires:

• Python
• MinIO mc client
• gzip

Features:

• Compresses each directory on upload. Compression level is configurable (default gzip -9)
• Adds useful object metadata:

  {
    "X-Amz-Meta-Content-Md5": "8b0dcc24439db3359bdd926f025aa635",
    "X-Amz-Meta-Modalities": "CT,SR",
    "X-Amz-Meta-Total-Count": "4"
  }

• Verify checksum of existing objects, and --overwrite if specified

Directory format must be <prefix>/<YYYY>/<MM>/<DD>/<AccessionNumber>/, e.g., /PACS/2017/05/28/ABCD.

This can be used in a parallel loop like so:

$ find ~/tmp/PACS -mindepth 4 -maxdepth 4 -type d -print0 |
    xargs -P4 -0 -i bash -c './dicom-to-minio.py myminio/test-1/pacs ~/tmp/PACS ${1#/home/rkm/tmp/PACS/}' - "{}"
