how should I retrive images from conquestDicom server

[vishu2111]

hi,

how should I retrieve images from conquestDicom server because sendMoveRequest() method is not available.

[J. Riesmeier]

Could you please be more specific! What do you mean by "sendMoveRequest() method is not available"?

[vishu2111]

can you tell me how should I retrive dicom images from pacs server?

[J. Riesmeier]

This is still not very specific, so my answer will also be quite general: If you want to write your own program, see this example in the support Wiki (requires DCMTK snapshot 3.6.1); otherwise, use the movescu command line program.

this is the program. I am not getting
sendMOVERequest() method on scu object I have created. I am using dcmtk 3.6.
so what should I do?

Thank You ....

[J. Riesmeier]

As I told you in my previous posting (and as it is also written on the Wiki page), you need a more recent DCMTK snapshot version 3.6.1, and not the current release version 3.6.0!!

[vishu2111]

where should I get dcmtk 3.6.1.
Please provide me the link sor the same

Thanks...
