Abstract

A system and method for managing the archival and retention of data in a multiple-node PACS network. Data is distributed among network nodes such that a secondary node will not delete a received image study it has received from a primary node if the primary node is an originating source. Instead, the secondary node will execute data retention. Data retention is achieved by including a delete retention attribute within the metadata associated with the received image data on the secondary node and requiring that the secondary node enforce data retention if a data retention attribute is identified within the metadata stored on the secondary node.

Claims

1. A system for archiving and retention of image data within a multiple node image storage network, said system comprising:

(a) a primary network node for storing and sending transmitted image data, where said transmitted image data includes metadata;

(b) a secondary network node coupled to the primary network node for receiving and storing the transmitted image data as received image data, where said received image data includes metadata,

(c) said secondary network node also including a data protection module configured for;

(i) determining whether the primary network node is the originating source of the image data;

(ii) if (i) is true, then including a data retention attribute within the metadata for the received image data stored on the secondary network node; and

(iii) reading the metadata on the secondary network node and enforcing data retention if the metadata includes a data retention attribute.

2. The system of claim 1, wherein data retention consists of ensuring that the received image data is not deleted from the secondary network node.

3. The system of claim 1, wherein data retention consists of ensuring that the transmitted image data is not deleted from the primary network node.

4. The system of claim 1, wherein once the data retention attribute is included within the metadata for the received image data on the secondary network node, the primary network node deletes the transmitted image data from the primary network node.

5. The system of claim 1, wherein the image storage network is a PACS network and the primary and secondary network nodes are primary and secondary PACS.

6. The system of claim 1, wherein the transmitted and received image data is medical imaging data according to the DICOM specification.

7. The system of claim 1, wherein the secondary network node is also configured to send the received image data and wherein the system further comprises a third network node coupled to the secondary network node for receiving the received image data as twice received image data, and wherein said third network node also includes a data protection module configured for:

(iv) determining whether the secondary network node is the originating source of the image data;

(v) if (iv) is true, then including a data retention attribute within the metadata for the twice received image data on the third network node; and

(vi) reading the metadata on the third network node and enforcing data retention if the metadata includes a data retention attribute.

8. A method for archiving and retention of image data within a multiple node image storage network having primary and secondary network nodes, said method comprising:

(a) storing transmitted image data on the primary network node and sending transmitted image data to the secondary network node, where said transmitted image data includes metadata;

(b) receiving and storing the transmitted image data as received image data on the secondary network node, where said received image data includes metadata,

(c) determining whether the primary network node is the originating source of the image data;

(d) if (c) is true, then including a data retention attribute within the metadata for the received image data stored on the secondary network node; and

(e) reading the metadata on the secondary network node and enforcing data retention if the metadata includes a data retention attribute.

9. The method of claim 8, wherein data retention consists of ensuring that the received image data is not deleted from the secondary network node.

10. The method of claim 8, wherein data retention consists of ensuring that the transmitted image data is not deleted from the primary network node.

11. The method of claim 8, wherein once the data retention attribute is included within the metadata for the received image data on the secondary network node, the primary network node deletes the transmitted image data from the primary network node.

12. The method of claim 8, wherein the image storage network is a PACS network and the primary and secondary network nodes are primary and secondary PACS.

13. The method of claim 8, wherein the transmitted and received image data is medical imaging data according to the DICOM specification.

14. The method of claim 8, wherein the secondary network node is also configured to send the received image data and wherein the system further comprises a third network node coupled to the secondary network node for receiving the received image data as twice received image data, and further comprises:

(i) determining whether the secondary network node is the originating source of the image data;

(ii) if (i) is true, then including a data retention attribute within the metadata for the twice received image data on the third network node; and

(iii) reading the metadata on the third network node and enforcing data retention if the metadata includes a data retention attribute.

15. A non-transitory computer-readable medium upon which a plurality of instructions are stored, the instructions for performing the steps of the method as claimed in claim 8.
