Conquest DICOM Server 1.5.0c released

Hi Conquest users and friends,

This is the long awaited 1.5.0c release. Much time has gone into bug fixes and json integration culminating in a first release of DICOMWeb functionality.

You can download the release here:

http://natura-ingenium.nl/dicomserver/dicomserver150c.zip

This is the corresponding Github commit for 1.5.0c:

https://github.com/marcelvanhe…83a796ac54416c6d5f24d7517

New features are: Fixes, Json and DICOMWeb support; regenerate with wildcard; hash anonymisation; allow rename images; Docker examples; sample webpages with DICOMWeb based viewers from Ohif and Luiz Oliveira, who greatly helped the DICOMWeb work.

As usual you can update by extracting dgate.exe or dgate64.exe and conquestdicomserver.exe, but also quite a few other files have changed - mainly in the web interface, lua code and installer. The web interface no longer required cgi, but uses PhP instead.

The latest source code (1.5.0c+) can be browsed on: https://github.com/marcelvanherk/Conquest-DICOM-Server

Please report bugs and successes!

Marcel

This is the buglist, starting with leftover bugs from earlier versions, per category:

Documentation bugs

D1) process study by file.lua does not allow () around argument (changed on Git)

GUI bugs

G1) browse tab does not work if user of server service and server gui are differerent.

Web interface bugs

DICOM Communication bugs

C1) Multiple instance matching incomplete

Installer bugs or limitations (low priority)

I1) last line of dicom.ini does not read if no CR - futured

I2) web installer should copy OHIF (in github) and luiz html folders and compile servertask

I3) Web installer on windows does not offer a 'regen' by itself

I4) Fedora uses /var/www, and nohup has an issue. Therefore provide specific web install scripts for other linux flavours, e.g. fedora.sh. Fedora also requires "sudo setenforce Permissive" for the web server and install to work; also acrnema.map must be copied locally to the cgi-bin/newweb folder rather than pointing to the server folder.

I5) Oracle linux issues see below; add mysql/mariadb option

Unconfirmed bugs:

U1) I was also expecting DicomObject:Read('stu\ser\sop') to work with virtual servers but I tested it again and sadly no luck there

U2) Show header in wadoviewer (wado text) open sometimes as dgate.exe downloads

Below ---- newly found bugs for 1.5.0c will be collected (also see above)

N1) Too long queries do not give a proper error message in GUI

N2) luaSetVR does not padd odd string to even (fix on Github)

N3) Need retry SqliteExec on SQLITE_LOCKED (fix on Github)

N5) Dicom printing from script or gui fails for compressed images

N8) DICOMWeb app was hardcoded for AE CONQUESTSRV, fix sneaked into the release zip, 1 sept 2022

------------ Release

N9) Internal networking is unreliable on Centos7

N10) dicomweb frame code boundary string is incorrect (fix on Git)

N11) studymodality did not display in newweb studies list (fix on Git)

N12) .htaccess in app/ohif has rewriterules reversed (fix on Git)

N13) data processed though incoming has CallingAE of 16 spaces in ImportConverter

N14) progressbar in GUI fails to close on very short operations from browser

N15) export:xx,,,,binary does not work

N16) Change or modify should not allow empty patientIDs

N17) default api path in ohiftop should not refer to localhost e.g. wadoUriRoot: '/api/dicom/wadouri' (fix on Git)

N18) dgatesop.lst is out of sync with the GUI on install (fix on Git)

N19) api query on modality does not pass query parameters (fix on Git)

N20) SCP/SCU Role Selection Sub-Item Structure is not sent (fix on Git)

N21) Update license to Apache

N22) Add optional delay to incoming scanner to avoid reading partial files (when 'at' does not block) (fix on Git)

N23) The GUI ignores ACRNemaMap in dicom.ini

N24) Ladle on Linux: 1. The file lua/JSON.lua needs to be renamed to lua/json.lua; 2. All the urls contain dgate.exe eg http://127.0.0.1:8086/cgi-bin/…match=&patientnamematch=*; Ladle now also uses app/newweb and app/ohif - deprecating cgi-bin interface (fix on Git)

N25) app/newweb may add HTML header to zip files if using userlogin (not confirmed)

N26) Association.ConnectedIP is unreliable; Proposed fix on Git using thread local storage by msz-kp

N27) the "by" clause is not checked in into_queue_unique(q, data, 230), extend to 490 characters. (fix on Git)

N28 ) servertask --deletepatient: acts as if it is --dolua. (fix on Git)

N29) The supplied postgress DLL uses a deprecated login method can use libcrypto-3-x64.dll; libiconv-2.dll; libintl-9.dll; libpq(64).dll; libssl-3-x64.dll; libwinpthread-1.dll from recent release

N30) Set utf8todb and utf8fromdb for PostGres (fix on Git)

N31) C-GET compression was not functional and left group 2 items (fix on Git)

N32) Temp file in ladle script was not deleted (fix on Git)

Hi,

you need to fill in the worklist database from an external source, such as an HL7 file (example attached). The scanner queries this database.

Marcel

What file?

Marcel

Hi,

thanks for looking at this, I have done little work with Ladle on Linux. I will add you reports to the buglist, and fix them asap.

Marcel

The setting seems not to be saved in the configuration file.

Hi,

I think autodelete only works when there is a single MAG device.

Marcel

Thanks for the feedback but I will delete your post in case it may be a placeholder for spam.

I've downloaded the release from the provided link and checked out the corresponding Github commit. It's fantastic to see the new features, including fixes, Json and DICOMWeb support. The addition of regenerate with wildcard, hash anonymization, and the ability to rename images is very helpful. The Docker examples and the sample webpages with DICOMWeb based viewers from Ohif and Luiz Oliveira are also impressive contributions.

I appreciate the instructions on how to update by extracting the necessary files. It's good to know that there have been changes in the web interface, lua code, and installer. The transition from CGI to PhP for the web interface sounds like a positive improvement.

Hi,

hi try http://127.0.0.1:8086/app/ohif and /app/newweb. DICOMWeb is at /api/dicom. It is served by the internal server (for small loads) at port 8086. Use apache+php, then served at port 80.

Marcel

Yes, no problem
