Weasis comand syntax: dicom:rs

[Victor S]

Hello and happy holidays

I have Weasis installed and working fine with a DCM4CHEE server. 

I configured the DCM4CHEE server in Weasis 3.5.4, in "File/Preferences", "DICOM node list", "DICOM node" -> "ADD New" with the following properties:

AE Title: DCM4CHEE
Hostname: 10.116.84.126
Port: 11112
Usage type: Retrieve

Using these settings I can successfully retrieve studies from the DICOM server but I need to display studies programmatically so I would like to use Weasis commands.

I read the commands from here and I can successfully connect to "Apache Felix gogo" with "telnet localhost 17179" but I can't find the right syntax to load a study.

I tried many commands but I got no success yet. This is what I tried last: 

dicom:rs --url "http://10.116.84.126:11112/dcm4chee-arc/aets/DCM4CHEE/rs" -r "&studyUID={1.3.12.2.1107.5.3.34.31085.1.20190710173010}" --query-ext "&includedefaults=false"

Thank you

1. URL should be encoded before passing it to weasis?

2. weasis command should start with $, like "$dicom:get -w ....." or "$dicom:rs ..."

3. command line launch: "open weasis://{}

1. I don't use a browser so I don't think I need to encode the URL - I just try to use telnet as described here: https://nroduit.github.io/en/basics/commands/

    I also tried a browser but I think telnet should be more easy to debug as I remove some complexity.

2. In telnet mode, according to documentation from the link above, there should be no $ before the command.

3. Weasis is already opened, otherwise I could not connect with telnet.

But I did tried to encode the url and to add $ before the command but in those cases I receive the error: "gogo: SyntaxError: bad expression:"

I think the URL is wring but I don't know what to write. 

When I execute this command:

dicom:rs --url "http://10.116.84.126:11112/dcm4chee-arc/aets/DCM4CHEE/rs" -r "&studyUID={1.3.12.2.1107.5.3.34.31085.1.20190710173010}" --query-ext "&includedefaults=false"


in weasis logs I can see the folowing message: 

23.12.2019 11:26:54.078 *DEBUG* [Dicom Model-pool-8-thread-1] org.weasis.dicom.explorer.rs.RsQueryResult: QIDO-RS request: http://10.116.84.126:11112/dcm4chee-arc/aets/DCM4CHEE/rs/studies?0020000D={1.3.12.2.1107.5.3.34.31085.1.20190710173010}&includefield=00080020,00080030,00080050,00080061,00080090,00081030,00100010,00100020,00100021,00100030,00100040,0020000D,00200010&includedefaults=false

 at org.weasis.core.api.util.NetworkUtil.readResponse(NetworkUtil.java)

In the wildfly log I have:

11:30:12,446 INFO  [org.dcm4che3.net.Association] (EE-ManagedExecutorService-default-Thread-5) /10.116.84.126:11112<-/10.8.15.10:51592(2): i/o exception: java.io.EOFException in State: Sta2 - Transport connection open

I don't know what "unrecognized PDU" means.

I think the URL is wrong - port I used is 11112 so tried with the port 8080 - so the URL is now http://10.116.84.126:8080/dcm4chee-arc/aets/DCM4CHEE/rs

I also tried with a access_token like this:

dicom:rs --url "http://10.116.84.126:8080/dcm4chee-arc/aets/DCM4CHEE/rs" -r "&studyUID={1.3.12.2.1107.5.3.34.31085.1.20190710173010}" --query-ext "&includedefaults=false" -H "Authorization: &access_token={...long string....}"

In this case the Weasis error is:

23.12.2019 11:31:57.429 *DEBUG* [Dicom Model-pool-8-thread-1] org.weasis.dicom.explorer.rs.RsQueryResult: QIDO-RS request: http://10.116.84.126:8080/dcm4chee-arc/aets/DCM4CHEE/rs/studies?0020000D={1.3.12.2.1107.5.3.34.31085.1.20190710173010}&includefield=00080020,00080030,00080050,00080061,00080090,00081030,00100010,00100020,00100021,00100030,00100040,0020000D,00200010&includedefaults=false

 at org.weasis.core.api.util.NetworkUtil.readResponse(NetworkUtil.java)

and at Wildfly log I have nothing in this case.

I think I'm missing something essential.

Thank you.

From telnet, you can try the following command to download directly from the Orthanc web PACS:

dicom:rs --url "https://demo.orthanc-server.com/dicom-web" -r "patientID=5Yp0E" --accept-ext=";"

The URL configuration for dcm4chee UI is specific (to inject some variables like the UIDs). The common syntax of QUERYPARAMS in dicom:rs is derived from weasis-pacs-connector or IID IHE profile. Try to replace:

dicom:rs --url "http://10.116.84.126:11112/dcm4chee-arc/aets/DCM4CHEE/rs" -r "&studyUID={1.3.12.2.1107.5.3.34.31085.1.20190710173010}" --query-ext "&includedefaults=false"

with

dicom:rs --url "http://10.116.84.126:11112/dcm4chee-arc/aets/DCM4CHEE/rs" -r "studyUID=1.3.12.2.1107.5.3.34.31085.1.20190710173010" --query-ext "&includedefaults=false"

Also trying to launch weasis from command line like this:

PS C:\Program Files\Weasis> .\weasis $dicom:rs --url "http://pacsrack.belroza.local:8080/dcm4chee-arc/aets/DCM4CHEE/rs" -r "&patientID=2"  --query-ext "&includedefaults=false"

Weasis opens but does not load any images, not showing any errors either.

Whats the mistake?

Weasis 3.5.4, dcm4chee-arc 5.21

The question above was about how to use commands through telnet. It would be useful for readers to create a new post so that they can follow a discussion about only one topic.

Start by reading how to use the weasis protocol: https://nroduit.github.io/en/getting-started/weasis-protocol/

You don't' need to know where weasis is installed and you must encode the command part with an online URL encoder or from your favorite script language.
