Abstract

A method includes sending from a first medical device to a second medical device a request for data using a communication protocol that includes messages for conveying medical measurement results. In response to the request, at least one message is produced in the second medical device that includes the requested data and a dummy payload instead of the medical measurement results, and the at least one message is sent from the second medical device to the first medical device using the communication protocol.

First claim

The invention claimed is:

1. A method, comprising:
sending over a network from a first medical device to a second medical device a request for data using a non-real-time communication protocol that comprises messages for conveying medical measurement results; and
in response to the request, producing in the second medical device at least one message that comprises the requested data and a dummy payload instead of the medical measurement results, and sending over the network the at least one message from the second medical device to the first medical device using the communication protocol;
wherein at least one network association between the first and second medical devices is opened when the first medical device sends the request to the second medical device and is closed when the network association is terminated by the first medical device;
wherein sending the at least one message comprises sending the data in multiple messages in response to the request while the at least one association is open; and
wherein the medical measurement results comprise an image, and wherein the dummy data comprises a dummy image.

2. The method according to claim 1 , wherein sending the request comprises opening at least one association between the first medical device and the second medical device, and wherein sending the at least one message comprises sending the data in one or more bursts while the at least one association is open.

3. The method according to claim 1 , wherein the communication protocol comprises a Digital Imaging and Communications in Medicine (DICOM) protocol.

4. The method according to claim 1 , wherein the first medical device comprises a position tracking system.

5. The method according to claim 1 , wherein the second medical device comprises a fluoroscopic imaging system.

6. The method according to claim 1 , wherein the first medical device comprises a position tracking system, wherein the second medical device comprises a fluoroscopic imaging system, and wherein sending the at least one message comprises sending one or more messages that report respective spatial positions of the fluoroscopic imaging system.

7. The method according to claim 6 , and comprising presenting the reported positions of the fluoroscopic imaging system to an operator, using the position tracking system, without activating the fluoroscopic imaging system.

8. The method according to claim 6 , and comprising compensating, based on the reported positions, for a distortion caused by the fluoroscopic imaging system to a magnetic field of the position tracking system.

9. A system, comprising:
a first medical device, which is configured to send over a network a request for data using a non-real-time communication protocol that comprises messages for conveying medical measurement results; and
a second medical device, which is configured to produce, in response to the request, at least one message that comprises the requested data and a dummy payload instead of the medical measurement results, and to send over the network the at least one message to the first medical device using the communication protocol;
wherein at least one network association between the first and second medical devices is opened when the medical session is initiated, and is closed when the network association is terminated by the first medical device;
wherein the second medical device is configured to send the data in multiple messages in response to the request while the at least one association is open; and
wherein the medical measurement results comprise an image, and wherein the dummy data comprises a dummy image.

10. The system according to claim 9 , wherein the first and the second medical devices are configured to open at least one association between the first medical device and the second medical device upon sending the request, and wherein the second medical device is configured to send the data in one or more bursts while the at least one association is open.

11. The system according to claim 9 , wherein the communication protocol comprises a Digital Imaging and Communications in Medicine (DICOM) protocol.

12. The system according to claim 9 , wherein the first medical device comprises a position tracking system.

13. The system according to claim 9 , wherein the second medical device comprises a fluoroscopic imaging system.

14. The system according to claim 9 , wherein the first medical device comprises a position tracking system, and wherein the second medical device comprises a fluoroscopic imaging system that is configured to send, in response to the request, one or more messages that report respective spatial positions of the fluoroscopic imaging system.

15. The system according to claim 14 , wherein the position tracking system is configured to present the reported positions of the fluoroscopic imaging system to an operator, without activation of the fluoroscopic imaging system.

16. The system according to claim 14 , wherein the magnetic position tracking system is configured to compensate, based on the reported positions, for a distortion caused by the fluoroscopic imaging system to a magnetic field of the position tracking system.
