11. The image management system as recited in claim 10 in which one of said parameters is the subject of the image.

12. The image management system as recited in claim 7 in which one of said parameters is the subject of the image.

13. The image management system as recited in claim 1 in which the metadata further includes information related to at least one of the patient, a patient study, a series, a patient body part, an imaging modality, and a procedure type.

14. The image management system as recited in claim 2 which includes an audit log stored in the database and the database management system is operable to record in the audit log information related to the metadata stored in the database.

15. The image management system as recited in claim 14 in which the information related to the metadata includes the dates on which the metadata is accessed and the identities of requesting users.

16. An image management system connected to receive messages which contain image data and associated metadata from an image producing device, which comprises:

a plurality of storage devices, where at least one of the storage devices has a cost characteristic that differs from the cost characteristics of the other storage devices;

means connected to receive the messages and a request message, wherein the request message includes a storage request category;

processor means coupled to the means for receiving and being operable to examine metadata in received messages and parameters in a set of stored rules related to the request category to determine in which of said plurality of storage devices the associated image data should be stored when the set of stored rules is related to the store category; and

means for storing the associated image data in the storage device determined by the processor means.

17. The image management system as recited in claim 16 in which one of the plurality of stored rules identifies one of said plurality of storage devices and one or more parameters that must be satisfied to store image data in that storage device.

18. The image management system as recited in claim 17 in which one of said parameters is the subject of the image and the metadata indicates the subject of its associated image data.

19. The image management system as recited in claim 17 which includes a workstation coupled to the processor means for enabling a user to input and edit said stored rules.

20. The image management system as recited in claim 17 in which:

the request message further includes a restore request category;
