request an authentication key;

responsive to receiving an authentication key of the authenticated user, allow modification of the default protocol by the authenticated user; and

responsive to receiving an authentication key of a non-authenticated another user, restrict modification of the default protocol by the non-authenticated user.

6. The system of claim 5 , wherein the computing device includes further instructions executable to:

responsive to the subsequent request to perform the imaging scan, output, to the display or another display operably coupled to the computing device, the protocol manager interface including a workflow comprising the one or more displayed action items of the modified protocol.

7. The system of claim 5 , wherein the protocol manager interface displayed for receiving input from the authenticated user is distinct from the protocol manager interface displaying the workflow to the non-authenticated user.

8. The system of claim 6 , wherein the input from the authenticated user includes selection, on the protocol manager interface, of an action item from the one or more displayed action items, and wherein the computing device includes further instructions executable to:

responsive to the input from the authenticated user,

display a message box associated with the selected action item;

receive content in the displayed message box from the authenticated user;

automatically display the received content in the selected action item while removing existing content from being displayed in the selected action item; and

when performing the imaging scan, output the workflow with the selected action item displaying the received content.

9. The system of claim 8 , wherein the received content specifies one or more new action items linked downstream of the selected action item, and wherein the computing device includes further instructions executable to:

upon receiving the content, automatically remove all action items of the default protocol downstream of the selected action item;

populate the modified protocol with the one or more new action items displayed downstream of the selected action item; and

when performing the imaging scan, output the workflow with the one or more new action items displayed downstream of the selected action item.

10. The system of claim 8 , wherein the displayed message box further includes category elements categorizing the modification to the selected action item, the category elements including at least a first category element associated with a guidance message and a second category element associated with a decision point, wherein the displayed message box prompts the authenticated user to select one of the first and second category element, and wherein when the second category element is selected, the received content includes at a first set of new action items associated with a first response element of the decision point and a second, different set of new action items associated with a second response element of the decision point.

11. The system of claim 10 , wherein the computing device includes further instructions executable to:

at a time of the imaging scan, prompt the non-authenticated user to select one of the first and second response element;

responsive to selection of the first response element, output the workflow with the first set of new action items displayed downstream of the selected action item while removing all action items of the default protocol downstream of the selected action item; and

responsive to selection of the second response element, output the workflow with the second set of new action items displayed downstream of the selected action item while removing all action items of the default protocol downstream of the selected action item.

12. The system of claim 1 , wherein the computing device includes further instructions executable to:

store the modified protocol in a protocol library as a function of the default protocol; and

modify a visual attribute of the stored modified protocol including a visual attribute of the one or more modified action items, the modified visual attribute distinguishing the modified protocol from the default protocol in the protocol library.

13. A system, comprising:

a display; and

a computing device operably coupled to the display and storing instructions executable to:

output, to the display, for an authenticated user, a first displayed protocol manager interface including a default manufacturer-installed protocol for an imaging system, the displayed default protocol including one or more action items displayed in a sequence;

responsive to input from the authenticated user, modify, at the displayed first user interface, the default protocol including modifying the one or more displayed action items and/or the sequence; and store the modified protocol along with the default protocol in a protocol library; and

output, to the display or another display operably coupled to the computing device, for the authenticated user or a non-authenticated user, a second protocol manager interface including a workflow displayed during the imaging scan, the displayed workflow comprising the one or more displayed action items of the modified protocol, wherein the imaging system is a computerized tomography imaging system, wherein the modified protocol includes imaging system parameters including gantry motor setting, table motor settings, and X-ray source voltage and current settings; and wherein the computing device includes further instructions executable to automatically operate the imaging system in accordance with the imaging system parameters defined in the modified protocol during the imaging scan.

14. The system of claim 13 , wherein the computing device includes further instructions executable to:

receive, on the first user interface, the input from the authenticated user before the imaging scan, including a selection of an action item, for modification, from the one or more action items of the default protocol, new content with which to modify the selected action item, and a set of new action items linked to the selected action item, the set of new action items including action items from another default protocol or another modified protocol; and

display on the second user interface, during the imaging scan, the workflow with prior content of the selected action item replaced with the new content, and with action items of the default protocol downstream of the selected action item replaced with the set of new actions items.

15. The system of claim 14 , wherein the computing device includes further instructions executable to:

display, on the first and second user interface, the selected action item with a visual attribute that is different from the visual attribute of remaining unselected action items of the modified protocol; and

in response to input from the authenticated or non-authenticated user, display a comparison of the selected action item of the default protocol with the selected action item of the modified protocol.

16. The system of claim 13 , wherein the computing device includes instructions executable to: responsive to the authenticated user modifying the default protocol, send a notification to the manufacturer of the imaging system, the notification including the modified protocol.

17. A method for a computed tomography (CT) imaging system, comprising:

displaying a default protocol defining a default workflow for operating the CT imaging system during a scan, the default protocol including one or more action items executed in a sequence; at least a portion of the one or more action items specifying imaging system parameters for the imaging scan;
