McKesson PACS system - product name is Horizon Medical Imaging running version 11.5.1

Is there any reason that I would not be able to send JPEG 2000 Dicom Images from my ClearCanvas Server to the product mentioned above?  We currently have a Novarad system that has no issues sending studies to it.

I either get :

Unexpected Network Error: Unknown
or
Cannot Understand

I've adjusted some of the buffer send and rec sizes in the config file and rebooted... but it's still broke.

On the other end... Here is some errors they sent to us:

____

We’re getting an uneven length error in the C-STORE request.
 
These usually point to an issue on the modality (in this case the novarad server) side of things.  Other import requests from modalities at the site are coming in fine.

Thank you for taking the time to provide insight.

I would concur, these types of errors usually point to bad DICOM data.

I guess the first step would be to look at the Study Details for the study, and specifically at the Study Storage tab. This will confirm the transfer syntax for the study is actually JPEG2000. The second step would be to actually capture a log file when the error occurs. When a codec doesn't exist for an image that is compressed, we're supposed to only send the image out in the compressed transfer syntax. It almost appears like the image is compressed, but we attempt to send the image as uncompressed.

Anyways, if you could let us know the stored transfer syntax for the study, then a log when attempting the transfer and failing, we may be able to help.

novapacs has a setting called "VR Toggle" that is enabled on your system. this is why it is accepting this study.

can you provide more of your igen log from your HMI system?

Sorry all.  I had to step away from this project for a while.  I appreciate the help and I hope to post more details later today or tomorrow.

Steve,

Here are the details from the study tab. I'm not sure I know which/what log you are wanting. Would you please tell me how to get this log?

It looks like you've confirmed that the images are encoded as lossy JPEG 2000, according to the ImageServer.

The log files are in the "Logs" directory of your install directory. You should be able to just test the send to the McKesson system, then open the log file for today, and see if there's an error. Searching by the AE Title of the McKesson system in the log should help you find the appropriate logs. Make sure you match up the timestamp to when you ran the test, in case there's other activity in the logs. I guess we're looking for some sort of error that occurs, and potentially some other informational logs about how the ImageServer is attempting to send the study.

From the logs, it looks like we are negotiating things properly. The JPEG 2000 transfer syntax is being negotiated, and from your previous post, the study is encoded as JPEG 2000 according to the ImageServer.

Would it be possible for you to send the specific study to another application and see if it can receive it? Seems like that would help pinpoint if the problem is in our software or the McKesson software.

To another AE at a different facility? I believe they are all the same solution at the facilities.

How about to another application like eFilm or something similar that can support JPEG2000 transfers?
