Abstract

The present invention provides a computer-readable storage medium including a set of instructions for a computer. The instructions include an access routine, a tracking routine, and a modifying routine. The access routine is configured to communicate a default hanging protocol between a network server and a display workstation. The default hanging protocol includes at least one default display rule for displaying a plurality of images at the display workstation. The default display rule is capable of directing the display workstation to present each of the images at a location on a display device of the display workstation and/or in a sequence in which each of the images is presented at the display workstation. The tracking routine is configured to monitor a selection of an additional display rule. The modifying routine is configured to dynamically modify the default hanging protocol based on the selection.

9. The set of instructions of claim 8, wherein said modifying routine is configured to modify said default hanging protocol after one or more of:

said number of times said additional display rule is selected exceeds one or more thresholds; and

said number of times said sequence of said additional display rules is selected exceeds one or more of said thresholds.

10. The set of instructions of claim 9, wherein said one or more of said thresholds are individually customizable.

11. The set of instructions of claim 1, wherein said modifying routine is configured to modify said default hanging protocol after a user is prompted for and provides permission to modify said default hanging protocol.

12. The set of instructions of claim 1, wherein said modifying routine is configured to make a modification to said default hanging protocol in order to create a modified default hanging protocol,

wherein said modification is based on at least a manual selection of said additional display rule by a user and said access routine is configured to communicate said modified default hanging protocol to at least one other user.

13. A method for dynamically altering a default hanging protocol, said method including:

providing access to said default hanging protocol, said default hanging protocol including at least one display rule, said display rule employed to direct a display workstation to present each of a plurality of images in a location on a display device and/or in a sequence in which each of said images is presented on said display device;

providing a tracking system capable of monitoring a selection of an additional display rule; and

providing a hanging protocol editor capable of dynamically creating a modified default hanging protocol, said modified default hanging protocol including said default hanging protocol and a modification to said default hanging protocol, said modification based on at least said selection of said at least one additional display rule.

14. The method of claim 13, wherein said step of providing access includes providing a set of instructions stored on a computer-readable storage medium capable of being communicated between a server and a display workstation, said set of instructions capable of performing said steps of providing said tracking system and providing said hanging protocol editor.

15. The method of claim 13, wherein said additional display rule is selected in order to alter one or more of:

said location at which each of said images is presented on said display device;

a location at which an additional image is presented on said display device;

said sequence in which each of said images is presented at said display workstation; and

a sequence in which a plurality of additional images is presented at said display workstation.

16. The method of claim 13, wherein said default hanging protocol is selected from a plurality of default hanging protocols based on one or more of:

a pre-processing function applied to at least one of said images; and

a computer-aided diagnosis of at least one of said images.

17. The method of claim 13, wherein said step of providing access includes providing access to said default hanging protocol after an identity of a user is authorized.

18. The method of claim 13, wherein said step of providing said tracking system includes said tracking system being capable of monitoring one or more of:
