Permissions control access to the functionality in the system. Permissions are role-based, meaning that you set permissions for groups of users. For example, when you define a set of permissions for the Clinicians role, all clinicians belonging to that role automatically inherit those permissions.
You can create two types of permissions:
General—give general access to functionality. They specify whether a user can see and use entire areas of the application or has access to specific tools. For example, you allow only certain roles access to diagnostic tools such as Histogram Equalization, whereas others, such as nurses, are not given access to this tool.
Study-Based—give access to functionality for a given set of studies. For example, you can implement a policy that allows radiologists full edit access to studies in the radiology department, but only view access to studies in the cardiology department.
To create permissions
From the Configure drawer menu
, select Users and Roles.In the navigation pane, select the role to create the permission for.
All of the roles and users beneath that role inherit the permission.
In the details pane, expand the Permissions bar.
Depending on the type of permission to create, switch to the General or Study-Based tab.
In the For permission list, right-click and select New.
Type a name for the permission.
All permissions in IMPAX must have a unique name, even when in different roles.
Select the operations that are allowed with this permission.
For study-based permissions, create the study access rules for the permission.
The permission is created. The changes are saved automatically when you switch context.
 | Note: You must have at least one study-based permission for each role (inherited or not), which defines the set of studies the users in the role can access. Otherwise users will not have access to any studies. |
