ParaVision is designed as a multiple user/operator application. Each user can have multiple operators. Any user data (MR data, protocols, scan programs, RF coil configurations, methods, etc.) is solely attributed to the user that is currently logged in into the application. However, this date is accessible for all operators that are using the same user account.

The user data are private per default. ParaVision provides the functionality to publish private user data and import them to other users. The pre-installed default user in ParaVision is »MR User«. In most cases all operators in a laboratory use the same MR User account. The Datasets are labeled with the name of individual operator. If for privacy reasons multiple users are required to protect user data from unauthorized access, additional users can be created and used.

In order to prevent unwanted damage of the scanner configuration, certain program features that relate to the configuration of the software are password protected. The password is requested every time when such a feature is started. The system administrator is responsible to set up an adequate policy within the group of users/operators.
