failing to export images or pull images from dcm4chee web3

[Wade Allen]

I tried to find someone with a similar problem but haven't been successful yet...this has been eating at me for a few days and I need some help.

I have installed dcm4chee-2.17.1-mysql on an ubuntu machine along with the web3 interface, and successfully used dcmsnd to load images. I can see them listed in the web3 interface, but I haven't yet gotten them to the computer that needs them. My destination computer is a Windows 7 machine.

The program I'm using can successfully view the images on dcm4chee using the AE: DCM4CHEE on port 11112. I created another AE to transfer the images to my desired destination computer, and I called the AE: VM1 on port 11113 with the proper local IP.  Both AEs echo just fine from the web3 Application Entities menu.

However, once I try to pull an image using a script on the destination computer, it fails with the following output on the destination computer:

Association Acknowledged (Max Send PDV: 16372)
Received C-Echo RQ: MsgID 1

AffectedSOPClassUID: =VerificationSOPClass
Data Set: Not Present

Association Release

If I try to use the export button on the web3 interface to send an image using my VM1 AE, it also fails, with the following error on the web3 popup:

and the following is the end of a long stream of output from the dcm4chee machine:

I'm stuck! I don't know what I might be missing, and learning about this on my own has been difficult so far. Can someone see what I'm missing, or point me in the right direction to get an image transfer working? Thanks!

 "I created another AE to transfer the images to my desired destination computer, and I called the AE: VM1 on port 11113 with the proper local IP" - how/why did you do this?

Normally you add the AE,IP,Port of the destination to dcm4chee then export to it i.e. query DCM4CHEE and retrieve to the destination AE.

[Wade Allen]

Thanks for answering!

Unless I'm misunderstanding, I think I did what you're suggesting, fleetwoodfc. This is the first time I'm creating a PACS, though, so I surely did something wrong. Here's some more detail of what I did there:

1) Install dcm4chee and web interface
2) load images
3) create AE on the web interface with the following details (Title: VM1, Host: <destination computer's IP>, Port: 11113)
4) set up a listener script on the destination computer, through my program
5) tried the echo on the web interface...successful
6) chose an image on the web interface, tried to export with the destination AET: VM1...failed

What did I miss?

[fleetwoodfc]

Is VM1 a DICOM Store SCP ?

[Wade Allen]

VM1 is the title of the AE that refers to the destination computer. It has a storescp program on it, if that's what you mean?

The destination computer is a Windows 7 virtual machine running a listener script, and the machine has a file called storescp.exe that is called by the listener script. The listener is named pacs_listener.bat, the contents of which are below (with a few directories and names edited out):

CHCP 1252
start "pacs_listener" /min "<filepath of the storescp>" -v -od "<filepath of a destination subfolder>" -aet VM1 -dhl -ss CV -fe .dcm 11113

REM [PACS]
REM archive_folder = <filepath of a destination folder>
REM client_ae = VM1
REM client_port = 11113
REM host_name = <name of computer with DCM4chee installed>
REM host_ae = DCM4CHEE
REM host_port = 11112
REM echoscu --aetitle VM1 --call VM1 localhost 11113
REM findscu --aetitle VM1 --call DCM4CHEE --patient -k 0008,0052=PATIENT -k 0010,0010="*" -k 0010,0020="*" <name of computer with DCM4chee installed> 11112
REM movescu --aetitle VM1 --call DCM4CHEE --move VM1 --port 11113 --patient -k 0008,0052=PATIENT -k 0010,0010="*" <name of computer with DCM4chee installed> 11112

[fleetwoodfc]

The first thing to figure out is why the FileNotFound exception on DCM4CHEE - can you manually access the file /2013/9/12/15/E794ACD8/9C59BF4A/28481531

Great idea, I should have thought of that. Thanks for your extended help.

The file exists in my dcm4chee mysql server folder: /home/<username>/Documents/dcm4chee-2.17.1-mysql/server/default/2013/9/12/15/E794ACD8/9C59BF4A

It is a DICOM image file (about 535 kB) that I can see in a DICOM viewer.

NOTE that this is not the root directory...the filename starts under a Documents folder. If dcm4chee is calling /2013/9/... from root, it's not gonna find it. Let me flesh out that possibility.

Would permissions be an issue? We have a few usernames that have worked on this. I am not root, and thus am not the file's owner, but could change those. 

[Wade Allen]

Well, copying the files to root worked! I can export now without any problems.

I'm not sure why dcm4chee would store files in a different place than it expects them, unless for whatever reason there's an environmental variable that isn't being used properly to define the path...

Hrm. Well, unless you have any other ideas, I suppose I might be creating a script to do both a dcmsnd and mv every time I need to add a file.

Thanks so much for your help! Now that I have a working setup, I can play with it to understand more about why this happened.
