dgate --imagelister on (not) local DICOM system

Hi,

I new with Conquest and at this forum. Hello everyone.

I have a question about dgate option: dgate --imagelister. It only list images on "local" machine? In docs i found

Quote

--imagelister:srv|pat|ser|fmt|file List (local) files in a series

. If it only list "local" files for what purpose is "srv" parameter?

------------------------------------
Let me describe my problem.

I have case to receive DICOM images via AJAX HTTP request, depending on type (jpeg/gif/dicom). Main difficulty is that I have several instances of Conquest on several servers in different locations.
Given I have 3 instances of Conquest in different location:

- Conquest MAIN
- Conquest HOSPITAL
- Conquest SMALL

Only MAIN server is open for WAN. HOSPITAL and SMALL are behind firewall, but all together is in VPN.

Some SET UP info:

Os is Ubuntu 7 (wheezy).

On MAIN Conquest acrnema.map i define DICOM system map:

MAIN       127.0.0.1      5678 unHOSPITAL   10.100.100.2 5678 unSMALL      10.100.100.3 5678 un

On HOSPITAL Conquest acrnema.map i define DICOM system map:

MAIN   10.100.100.1      5678 un

On SMALL Conquest acrnema.map i define DICOM system map:

MAIN   10.100.100.1      5678 un

My idea is that:

ON "MAIN" Conquest i create a micro PHP proxy app. It accepts some parameters and run system dgate command with option --wadorequest:parameters. My proxy app parse dgate --wadorequest response, and forward it to requestor server. So i can use Conquest on MAIN as a gateway to HOSPITAL and SMALL. And it works fine.

Problem is to retrieve UIDs

According to APPENDIX 6 of Conquest doc, i try to find studyUID, instanceUID, imageUID using dgate database option to get required parameters for wadorequest.
Using --seriesfinder to get studyUID and seriesUID.
Using --imagelister to get imageUID, but it doesn't work.

My code:

/pacs/test/dgate --patientfinder:"{AETITLE from acrnema.map}|{some string}"  // works fine, return list of patients matching to {string} on specified {aetitle} location


/pacs/test/dgate --seriesfinder:"{AETITLE from acrnema.map}|{some string}"  // works fine, return list of series matching to {string} on specified {aetitle} location


/pacs/test/dgate --serieslister:"{AETITLE from acrnema.map}|{patientId}|{studyUID}"  // works fine, return list of series for specified {patient} and {study} on specified {aetitle} location


/pacs/test/dgate --imagelister:"{AETITLE from acrnema.map}|{patientId}|{seriesUID}"  // NOT WORK, response is empty. that's for all {aetitle} MAIN, HOSPITAL, SMALL

What I do wrong?
Maybe You have some similar case?
Some other ideas how to retrieve images from DICOM servers behind firewall over HTTP?

Hi,

Thanks Marcel. That helped me much.
I don't know why i missed --imagefinder option?
I didn't see it before.

Now when i use

/pacs/test/dgate --imagefinder:"{AETITLE from acrnema.map}|{string}"  // works perfectly

However 'str' arg for imagefinder allow to find image by Patient Name or Patient ID. I think this could be enought for me, but is there any way to find image by seriesUID?

Hi,

Thanks Marcel.
now i understand everything.
