Orthanc 0.9.0

[Sébastien Jodogne]

Dear Orthanc users, 

Orthanc 0.9.0 is out!

This major release notably features a DICOM Query/Retrieve client inside Orthanc Explorer, that is also accessible through the REST API. Other changes include the support of FreeBSD, many optimizations and bugfixes.

Enjoy,

Sébastien-

Thanks for this great release! :)  (Just had time after the school holidays to play around with 0.9.0).

A couple of things:

1. I've having trouble constructing a CURL request for modalities/{dicom}/query. I've tried modifying the requests from https://code.google.com/p/orthanc/wiki/FAQ#How_Can_I_Run_a_C-Find_SCU_Query_(experimental) (yes, I know they're the depreceated ones) but can't seem to retrieve the query IDs.

2. I'm having some problems using the Q/R from Explorer to Siemens Syngo.Via. (The Explorer Q/R works with my other systems, notably Osirix.) The query is formed properly (can be viewed in /queries), but no answers are returned. No error message appears in the Orthanc command line. I am attempting to change configurations but no such luck so far. (Something weird I noticed is that I can still successfully do a C-FIND using /modalities/SyngoVia/find )

Dear Emsy,

Thanks for your feedback!

1. Yes, the documentation is still very sparse and I'm currently working on it. I will also soon publish my set of integration tests for other people to have more sample code. In the meantime, here is a sample query:

# curl -X POST http://localhost:8042/modalities/pacs/query -d '{ "Level" : "Series", "Query" : { "PatientName" : "*JOD*" }}'

Then, you can trigger a retrieve of one answer to this query, with the modality whose AET is "SAMPLE" as a target, as follows:

# curl http://localhost:8042/queries/344455cc-45ff-4196-8f7d-7b43c20d402e/answers/0/retrieve -d 'SAMPLE'

Other useful URIs are listed in the reference of the REST API:

https://docs.google.com/spreadsheets/d/1muKHMIb9Br-59wfaQbDeLzAfKYsoWfDSXSmyt6P4EM8/pubhtml?gid=525933398&single=true

Obviously, you can monitor the behavior of Orthanc Explorer to get more insight about how to use this API (e.g. using the developer mode of Chromium or Firefox).

2. I unfortunately have no access to Syngo.Via, so I cannot provide any help on this topic. Maybe it does not support the SERIES query retrieve level, but only the STUDY one?

HTH,

Hi! Thanks for the sample query and the tip about using developer tools *embarrassed look*.

I've found the problem with querying Syngo.Via.

Here's the query/{id}/query?simplify generated by Orthanc Explorer

{
   "AccessionNumber" : "*",
   "PatientBirthDate" : "*",
   "PatientID" : "123456",
   "PatientName" : "*",
   "PatientSex" : "*",
   "SpecificCharacterSet" : "ISO_IR 192",
   "StudyDate" : "*",
   "StudyDescription" : "*"
}

I managed to successful query Syngo.Via by removing changing the date values from "*" to " ":

{
   "AccessionNumber" : "*",
   "PatientBirthDate" : " ",
   "PatientID" : "123456",
   "PatientName" : "*",
   "PatientSex" : "*",
   "SpecificCharacterSet" : "ISO_IR 192",
   "StudyDate" : " ",
   "StudyDescription" : "*"
}

Syngo.Via won't respond if date values are:

*

2015-

Syngo.Via will only respond if full dates are used:

19700101-

20150101-

-20141231

20150101-20150601

*Note: Because Orthanc Explorer always sends "*" in PatientBirthDate, Syngo.Via will never return an answer.

Gosh, I love playing around with this! 

Next issue (haven't had time to investigate this yet): QueryRetrieveLevel "Series" returns *EVERY* series in Osirix... ("Study" level works in Osirix. Both "Study" and "Series" levels work in Syngo.Via) 

Regards,

Emsy

Just a headsup:

To get Query/Retrieve working from Orthanc with AGFA Impax 6.x i had to add the "SyngoVia" patch to get it working.

 

Regards,

Robert

Dear Robert,

Thanks for your feedback! I have just added a new "AgfaImpax" modality manufacturer (that is currently only an alias for "SyngoVia" to make things clearer):
