The inheritance of preferences by roles and users in the hierarchy can be merged or non-merged. The following tables outlines which types of preferences are merged or non-merged so you can determine where to set these preferences in your hierarchy of roles and users.
There are two special categories of merged preferences: wizards and hanging protocols. When a user opens the Customize window, IMPAX 6.5.1 displays wizards and hanging protocols for the user and for all inherited roles. All wizards and hanging protocols are displayed even if multiple wizards and hanging protocols have the same name.
All automatically triggered wizards (for example, Patient Viewed trigger) are executed together, regardless if the wizard was created by the user or inherited from a parent role.
Hanging protocols do not follow the rule of user preferences overriding parent preferences. If there are multiple automatic hanging protocols with the same trigger (for example, MR spine), only the parent hanging protocol is applied.
 | Note: A user role can enable or disable wizards that are inherited from a parent role. |
Merged preferences
| Category | Type | Description |
|---|---|---|
| Toolbars | Merged by role, modality, and body part | The buttons in the top toolbar and context toolbar can be customized for each modality and body part. For each modality and body part, IMPAX first looks for user settings. If they do not exist, the toolbar settings from an inherited role are used. |
| Screen Formats and Display Settings | Merged by role, modality, and body part | The list of screen formats and display settings can be customized for each modality and body part (for example, Study View Mode, Series View Mode, and Window Level Default Scope). For each modality and body part, IMPAX first looks for user settings. If they do not exist, the screen format and display settings from an inherited role are used. |
| Modality settings | Merged by role, modality, and body part | The default tool, Window Level, and calibration settings can be customized for each modality and body part. For each modality and body part, IMPAX first looks for user settings. If they do not exist, the screen format and display settings from an inherited role are used. |
| Cine view settings | Merged by role, modality, and body part | The Cine Viewer settings can be customized for each modality and body part. For each modality and body part, IMPAX first looks for user settings. If they do not exist, the screen format and display settings from an inherited role are used. |
| Wizards | Merged by role | Wizards for the user and for all inherited roles are displayed in the Customize dialog. All wizards are displayed even if multiple wizards have the same name. All automatically triggered wizards (for example, Patient Viewed trigger) will run. You can enable or disable wizards from an inherited role. |
| Hanging protocols | Merged by role | Hanging protocols for the user and for all inherited roles are displayed in the Customize dialog. All wizards are displayed even if multiple wizards have the same name. If two automatic hanging protocols have the same triggers (for example, modality and body part) the inherited role hanging protocol takes precedence over the user hanging protocol. |
| Display Annotations | Merged by role and modality | The list of default annotations can be customized for each modality. Default annotations for the user and all inherited roles are displayed in the list. The user annotations and the inherited role annotations are separated by a dashed line. |
Non-merged preferences
| Category | Description |
|---|---|
| Comparative Review Sequence | The Comparative Review Sequence is not merged. Any user changes override role settings. |
| User Profile and Workflow | The User Profile settings (for example, Available Series palette, Configurable Study Save, and Workflow settings) are not merged. Any user changes override role settings. |
| Keyboard Shortcuts | The keyboard shortcut mappings are not merged. Any user changes override role level settings. |
| Window Level Presets | The window level presets are not merged. Any user changes override role settings. |
| Site Series Descriptions | The list of default series descriptions used to build hanging protocols is not merged. Any user changes override role settings. |
| Window position and sizing | IMPAX remembers the position and sizing of all popup windows. These implicit settings are not merged. Any user changes override role settings. |
