Abstract

A method and apparatus for extracting information from a medical image data and transferring the extracted information in a separate format from the medical image data is disclosed. A network element is employed to monitor a network for medical image data transmitted on a network. The network element monitors the data packets on the data network to identify and retrieve the data packets containing medical image data. The medical image is reconstructed and the network element identifies and extracts desired information from within the medical image data. The network element then compresses the medical image data, and separately formats the extracted information from the medical image data. The medical image data and the extracted information are then transmitted to the image archive system via the network.

Claims

1. A method for extracting information from a medical image, the method comprising the steps of:

receiving by a network element data packets containing image data;

reconstructing by the network element at least a portion of the image data from the retrieved data packets;

extracting by a network service in conjunction with the network element predetermined information from the reconstructed image data;

formatting by the network service in conjunction with the network element, the data message into a first format;

formatting by the network service in conjunction with the network element the extracted information into a second format; and

transmitting the data message in the first format to the image archive system and the extracted information in the second format.

2. The method of claim 1 wherein the step of receiving by a network element comprises the steps of:

monitoring, by the network element, a network for data packets containing the image data;

identifying, by the network element, data packets on the network containing the image data; and

retrieving, by the network element, from the network the identified data packets.

3. The method of claim 1 wherein the step of transmitting the extracted information includes transmitting the extracted information in an out of band signal.

4. The method of claim 1 wherein the step of extracting the predetermined information comprises the step of extracting predetermined commands from the image data.

5. The method of claim 1 wherein the predetermined information comprises metadata from the image data.

8. The method of claim 1 wherein the step of formatting the extracted information includes formatting the extracted information without a compression scheme.

9. The method of claim 1, wherein the image archive system is a picture archive and communication system (PACS) device.

6. The method of step 1 wherein the step of formatting the image data in a first format, includes formatting the image data using a first compression scheme.

7. The method of step 1 wherein the step of formatting the extracted information includes formatting the extracted information using a second compression scheme.

10. A system for extracting information from a medical image transmitted on a network, the system comprising:

a network element coupled to the network; and

a compression/extraction service associated with the network element and configured to;

receive a data packet containing image data;

reconstruct a portion of the image data from the retrieved packet;

extract predetermined information from the image data;

format the image data in a first format;

format the extracted information in a second format; and

transmit the image data in the first format and the extracted information in the second format to the image archive system.

11. The system of claim 10 wherein to receive data packets, the network element is further operative to:

monitor a network for a data packet containing image data;

identify data packets on the network containing the image data; and

retrieve the data packets identified as containing the image data.

12. The method of claim 11 wherein the network element is further configured to extract metadata from the image data.

14. The method of claim 10 wherein the network element is configured to transmit the extracted commands in an out of band signal.

16. The method of claim 10 wherein the network element is further configured to format the extracted information without compressing the extracted information.

17. The method of claim 10, wherein the image server and database system is a picture archive and communication system (PACS) device.

18. The system of claim 10 wherein the network element is operative to transmit the DICOM extracted commands in an out of band signal.

13. The method of step 12 wherein the network element is further configured to format the image data using a first compression scheme.

15. The method of step 10 wherein the network element is further configured to format the extracted information using a second compression scheme.
