Abstract

Claims (29)

1. A method for performing network based load balancing of medical image data among a plurality of image archive resources by a network service deployed on a network element implemented on the network, the method comprising the steps of:

monitoring, by the network service, a parameter associated with each of the plurality of image archive resources indicative of an available capacity of each of the plurality of image archive resources;

receiving, by the network service, medical image data to be load balanced to a selected at least one of the plurality of image archive resources, the medical image having embedded therein instructions associated with a task to be performed by the selected at least one of the plurality of image archive resources in connection with processing the medical image data, the task being addressed to the at least one image archive resource for execution by the at least one image archive resource and being embedded within a DICOM message;

extracting the instructions, by the network service, from the DICOM message, the instructions being associated with the task that is addressed to the at least one image archive resource for execution by the at least one image archive resource;

determining from the instructions, by the network service, a level of complexity of the task that is addressed to the at least one image archive resource for execution by the at least one image archive resource;

selecting, by the network service, at least one of the plurality of image archive resources to be used to perform the task in connection with processing the medical image data, the step of selecting using, as a selection function, the available capacity of each of the plurality of image archive resources and the level of complexity of the task that is to be performed by the selected at least one image archive resource; and

transferring, by the network service, the medical image data to the selected one of the plurality of image archive resources.

2. The method of claim 1 wherein the step of selecting comprises selecting the one of the image archive resources having the greatest available capacity relative to the complexity level of the task to be performed.

3. The method of claim 1 , wherein the plurality of image archive resources comprises a plurality of Picture Archive Systems (PACS).

4. The method of claim 3 wherein the parameter is one of the group consisting of the PACS server load, or the PACS storage time.

5. The method of claim 1 wherein, the parameter is an image archive resource load.

6. The method of claim 1 , wherein the selection function is further based on a priority level of the task and a priority level of the image archive resource.

7. The method of claim 6 , wherein the step of selecting comprises selecting the one of the plurality of image archive resources having a priority less than or equal to the priority level of the task.

8. An apparatus for performing network based load balancing of medical image data among a plurality of image archive resources, the apparatus comprising:

a network element coupled to a network and configured to send and receive data via the network; and

a network service coupled to the network element, the network service configured to:

monitor a parameter associated with each of the plurality of image archive resources indicative of an available capacity of each of the plurality of image archive resources;

receive medical image data to be load balanced to a selected at least one of the plurality of image archive resources, the medical image having embedded therein instructions associated with a task to be performed by the selected at least one of the plurality of image archive resources in connection with processing the medical image data, the task being addressed to the at least one image archive resource for execution by the at least one image archive resource and being embedded within a DICOM message;

extract the instructions from the DICOM message, the instructions being associated with the task that is addressed to the at least one image archive resource for execution by the at least one image archive resource;

determine from the instructions a level of complexity of the task that is addressed to the at least one image archive resource for execution by the at least one image archive resource; and

select at least one of the plurality of image archive resources to be used to perform the task in connection with processing the medical image data using, as a selection function, the available capacity of each of the plurality of image archive resources and the level of complexity of the task that is to be performed by the selected at least one image archive resource; and

transfer the medical image data to the selected one of the plurality of image archive resources.

9. The apparatus of claim 8 wherein the network service is operative to select the one of the image archive resources having the greatest available capacity relative to the complexity level of the task to be performed.

10. The apparatus of claim 8 , wherein the plurality of image archive resources comprises a plurality of Picture Archive System (PACS).

11. The apparatus of claim 10 wherein the parameter is one of the group consisting of the PACS server load or the PACS storage time.

12. The apparatus of claim 8 wherein the parameter is an image archive resource load.

13. The apparatus of claim 8 , wherein

the selection is further based on a priority level of the task and a priority level of the image archive resource.

14. The apparatus of claim 13 , wherein the selection is based on selecting the one of the plurality of image archive resources having a priority less than or equal to the priority level of the task.
