The only way to import images into the DICOM viewer right now is to upload directly using the import tool. This is problematic for two reasons: 1. large sets of data are handled better through Drive or Sync than a web interface and 2. data already in Box need to be downloaded and then imported (uploaded) again using the import tool, which is not practical when working with 10s-100s of GB of DICOM data. There should be a mechanism to import data already stored on Box into the DICOM viewer.

This may be similar to a different issue: https://pulse.box.com/forums/909778-help-shape-the-future-of-box/suggestions/36114310-direct-dicom-upload-endpoint-desired
