Abstract

The invention comprises a system and method for receiving a DICOM image file from a first DICOM storage service class user, employing rules on the DICOM image file and forwarding the DICOM image file to a second DICOM storage service class user in accordance with the rules. After router configuration information, remote server configuration information, routing rules information and replacement rules information is received from a user, a DICOM image file received over a communication network from the first DICOM storage service class user in accordance with the router configuration information is modified in accordance with the replacement rules information, and the modified DICOM image file is routed to the at least one computing device in accordance with the routing rules.

Claims

1. A method for receiving a DICOM image file from a first DICOM storage service class user, employing rules on the DICOM image file and forwarding the DICOM image file to a second DICOM storage service class user in accordance with the rules, the method comprising:

providing at least one automated processor operatively coupled to non-transitory processor readable media;

receiving, by the at least one automated processor from a user via an electronic user interface;

router configuration information, the router configuration information representing at least a DICOM storage service class provider for receiving the DICOM image file from the first DICOM storage service class user;

remote server configuration information, the remote server configuration information representing a plurality of computing devices operable to send or receive DICOM image files over a communication network;

routing rules information, the routing rules information representing first data conditions for transmitting to at least one of the plurality of computing devices the DICOM image file; and

replacement rules information, the replacement rules information representing second data conditions for modifying at least one DICOM tag data value in the DICOM image file;

receiving, by the at least one automated processor over the communication network the DICOM image file from the first DICOM storage service class user in accordance with the router configuration information, wherein the DICOM image file represents at least part of a medical study for a patient, and, further wherein the DICOM image file is in conformance with DICOM as existing on Feb. 22, 2005;

examining, by the at least one automated processor, the at least one DICOM tag data value in the DICOM image file and modifying, by the at least one automated processor, the at least one DICOM tag data value in the DICOM image file in accordance with the replacement rules information; and

examining, by the at least one automated processor, the routing rules information; and

routing, by the at least one automated processor, the modified DICOM image file to the one of the plurality of computing devices in accordance with the at least one modified DICOM tag data value in the DICOM image file and the routing rules information.

2. The method of claim 1, wherein the router configuration information includes at least one of a port number, a local application entity title, and a default server name.

3. The method of claim 2, wherein the DICOM image filed is received by a computing device represented by the default server name in the event no matching routing rules are met.

4. The method of claim 1, further comprising:

storing the user replacement rules information in at least one database;

storing the routing rules information in the at least one database;

storing the remote server configuration information in the at least one database; and

storing the router configuration information in the at least one database.

5. The method of claim 1, wherein the communication network is the internet.

6. The method of claim 1, wherein the electronic user interface includes graphical screen controls enabling the user to add, edit or delete the remote server configuration information, the routing rules information and the replacement rules information.

7. The method of claim 1, wherein the first and second data conditions are based upon values or formatting of data in DICOM data fields.

8. The method of claim 1, wherein the router configuration information includes an internet protocol address, an application entity title, and a port number.

9. The method of claim 1, wherein the DICOM image file is received in one DICOM format and routed in the one DICOM format.

10. The method of claim 9, wherein the DICOM format is JPEG lossless, Explicit VR Little Endian, Implicit VR Little Endian or JPEG Lossy.

11. The method of claim 1, further comprising:

examining a histogram of the DICOM image;

calculating an average pixel value and standard deviation; and

deriving an optimum window size and position based on the average pixel value and the standard deviation.

12. A system for receiving a DICOM image file from a first DICOM storage service class user, employing rules on the DICOM image file and forwarding the DICOM image file to a second DICOM storage service class user in accordance with the rules, the system comprising:

a computing device including an electronic user interface operable on the computing device to receive from a user;

router configuration information that represents at least a DICOM storage service class provider for receiving the DICOM image file from the first DICOM storage service class user;

remote server configuration information that represents a plurality of computing devices operable to send or receive DICOM image files over a communication network;

routing rules information that represents first data conditions for transmitting to at least one of the plurality computing devices the DICOM image file; and

replacement rules information that represents second data conditions for modifying at least one DICOM tag data value in the DICOM image file;

wherein the computing device is programmed and configured to;

receive over the communication network the DICOM image file from the first DICOM storage service class user in accordance with the router configuration information, wherein the DICOM image file represents at least part of a medical study for a patient, and, further wherein the DICOM image file is in conformance with DICOM as existing on Feb. 22, 2005;

examine the at least one DICOM tag data value in the DICOM image file and modify the at least one DICOM tag data value in the DICOM image file in accordance with the replacement rules information; and

examine the routing rules information and route the modified DICOM image file to the one of the plurality of computing devices in accordance with the at least one modified DICOM tag data value in the DICOM image file and the routing rules information.

13. The system of claim 12, wherein the router configuration information further includes at least one of a port number, a local application entity title, and a default server name.

14. The method of claim 13, wherein the DICOM image filed is received by a computing device represented by the default server name in the event no matching routing rules are met.

15. The system of claim 12, further comprising a database that stores the user replacement rules information, the routing rules information, the remote server configuration information and the router configuration information.

16. The system of claim 12, wherein the communication network is the internet.

17. The system of claim 12, wherein the electronic user interface includes graphical screen controls enabling the user to add, edit or delete the remote server configuration information, the routing rules information and the replacement rules information.

18. The system of claim 12, wherein the first and second data conditions are based upon values or formatting of data in DICOM data fields.

19. The system of claim 12, wherein the router configuration information further includes an internet protocol address, an application entity title, and a port number.

20. The system of claim 12, wherein the DICOM image file is received in one DICOM format and routed in the one DICOM format.

21. The system of claim 20, wherein the DICOM format is JPEG lossless, Explicit VR Little Endian, Implicit VR Little Endian or JPEG Lossy.

22. The system of claim 12, further comprising an automatic window size and position module operable to examine a histogram of the DICOM image, to calculate an average pixel value and standard deviation and to derive an optimum window size and position based on the average pixel value and the standard deviation.
