There are two entry points in the UI to initiate a download. The first is in the Request Management UI (Tab 3), the second is in the Cache Management UI (Tab 5).

Each of these entry points require users to configure download settings before download can proceed. Users must set up

1. A download location (where the downloaded studies will be stored).
2. Encryption options

Encrypted studies have obfuscated versions of file names for the studies, series, and images (as opposed to the unencrypted version that uses the study/series/images ID from DICOM headers ). In addition, an image cannot be viewed (in mi2b2 client or any other DICOM image viewer) without a correct key. The aim of encryption is to add an additional layer of protection on the imaging data.

This document describes the interface by which users can configure these settings. For details about the encryption algorithm, strength, and the process of encrypting downloaded images, please review to the technical note on Encryption.
