I used the following lines but get the following syntax error:

[lua]
QueryConverter0 = if Association.Calling ='MAYAM' then Data.Modality = 'CR' end
RetrieveConverter0 = if Association.Calling ='MAYAM' then Data.Modality = 'CR' end

Error
[PACS] *** lua syntax error [string "if Association.Calling ='MAYAM' then Data.Modality = 'CR' end"]:1: 'then' expected near '=' in 'if Association.Calling ='MAYAM' then Data.Modality = 'CR' end'

Please also guide me if i am wrong: QueryConverter0 command receive the query at server end and RetrieveConverter0 sends the modified result.

Please provide some more details on QueryConvertors and also how can i use them in lua scripting (example please).

--HM

Can you please provide me the list of query convertors and filters with little bit example.

I know that only the nodes registered on conquest can retrieve images from a study. But I need two things that I don't know if they can be done:

1-Can I limit some nodes to query and retrieve only one type (eg.: a specific node can access only CR studies, another one which can query and retrieve only XA studies...)?
2-Can I limit queries only to registered nodes? Only the registered nodes can retrieve the images, but all of them can query the existing studies. Is there any way to limit this?

What about my previous question in response to which i posted the dicom.ini file you requested.

Sorry for the late reply. Please find my dicom.ini enteries

MAGDevices = 6
MAGDevice0 = D:\Images\
MAGDevice1 = D:\QIH\
MAGDevice2 = D:\UMC\
MAGDevice3 = D:\AH\
MAGDevice4 = D:\PMH\
MAGDevice5 = D:\hY9\

NightlyCleanThreshhold = 0
NightlyMoveThreshhold = 0
NightlyMoveTarget =

ExportConverters =3
ExportConverter0 = copy %f to D:\TestFolder
ExportConverter1 = append "%d%t%t%t%u%t%t%t%i%t%t%t%s%n" to c:\log.txt
ExportConverter2 = save jpg as C:\JPG\%i-%m.jpg

[lua]
ImportConverter0 = dofile('storage.lua')

I wanted to know if i want to set a DICOM Tag of incoming Image and then forward it. Should i add these lines in the end or should i use lua to do the required tasks.

[lua]
ImportConvertor = 2
ImportConverter0 = dofile('hammad.lua')
ImportConverter1 = set 0008,0080 to "XXXXX"

On running the above line i get the following error

[PACS] *** lua run error [string "set (0008,0080) to "XXXXX""]:1: attempt to call global 'set' (a nil value) in 'set (0008,0080) to "XXXXX"'

Hi

Is there any way to put restriction that specific AET or Port only retrieve Axial, Sageital and Coronal images no volume data.

I want this to save my bandwidth and Doctors in Clinics only need Axial, Sageital and Coronal images to view no volume data.

Help Required.

Marcel i also figure some strange working in the flow and sequence of converters. Instead of Export Converter 0 to be executed first 1 is executed first then 0 and in the last 2. Why is that?? Appended below is my server log:-

[PACS] Exportconverter2.0 executes: save jpg as C:\JPG\10801-CR.jpg

I simply close the server four times and both converters start working. But i noticed that first export converters then import converters. In my case this sequence works.

--HM

Sure. But i will first test by changing the sequence . First Import Converter then Export Converter and update you.

--HM

But as i mentioned in my case only export converters were executed not import one.

Please update me is there any time difference between the execution of bot converters i mean import converters will run after x seconds after export or vice versa.

Hi

I had define three export converter that works fine . Details of Export converter is as follow:-
1. First Export Converter copy incoming images to a specified folder
2. Second Export Converter make a log file of the incoming dicom images.
3. Third Export Converter make Jpeg of incoming dicom images

All of the above three converters work fine. But when i add an Import Converter in the end of dicom.ini file that calls a lua script then Export Converters are executed but import converter don't call the lua script.

My dicom.ini file is something like this

ExportConverters = 3
ExportConverter0 = copy files to folder
ExportConverter1 = make log file
ExportConverter2 = make JPEG

[lua]
ImportConverter0 = dofile('script.lua')

And i also want to make one thing clear that Export Converter are always define before [lua] tag starts or i can define after the [lua] Import Converter ..........
In this scenario the export converter is not executed just like import converter .

Please also define the sequence in which both of them are define.

--HM

Yes they are same. No changes in the dicom.ini file.

These large images are of DX and Mammo. Even i simply unzip these images and placed even single image in incoming folder i get the same error and even by sending via dcm4chee toolkit. When i send these Mammo images to Mayam using dcm4chee toolkit and throw the images from its archive to Server console the server accepts the same images. WHY IS THAT????

I test this with all the images that give me error like Nuclear Medicine Images, Mammoo, DX and CR.

--HM

I am facing some issue of slow response and application hanging in new alpha release.

The scenario is like this :-

1. Copied dicom studies zip files and uncompressed in Conquest incoming folder (size almost 5GB)
2. Push Dicom Studies (uncompressed size almost 2 GB) using dcm4chee toolkit
3. Push Dicom Studies (uncompressed size almost 2 GB) again using dcm4chee toolkit
4. Push Dicom Studies (uncompressed size almost 650 MB) using EFILM
5. Push Dicom Studies (uncompressed size almost 1 GB) using MAYAM
6. Push Dicom Studies (uncompressed size almost 1 GB) using Clear Canvas Workstation
7. Query and Retrieve studies from conquest using MAYAM, EFILM, KODAK MXR, VITREA , Clear canvas and Weasis (via web interface)

And sometimes i also get this error message on server console :
"[PACS] ***VR:ReAlloc out of memory allocating 1342177280 bytes
[PACS] ***A fatal error occurred (out of memory) - closing server";

I restarted the server by clicking on "KILL AND RESTART SERVER" but no success until i close the whole application and start the application again.

At the time of error CPU utilization was around 45% and RAM used was around 55% to 75%.

But same test works fine with the older versions.

Thanks Marcel for your help and patience. That worked fine. I got it done via lua scripting.

--HM

Okie and how to add that newly created tag in each image (sorry because of lack of knowledge regarding conquest in detail working)...

i had added the private tag that you mentioned in dicom.sql and regenerate the database. Now this new filed with name HID is created in database. Now how can i set this field value?

I test your statement it returns 1 as per your comment. But how can i update it as you said that importconvertor will work after second image???

Please guide

Is this correct ???

in dicom.sql
{ 0x0009, 0x1234, "HOSPID", 10, SQL_C_CHAR, DT_STR },

hammad.lua file

iif Data.InstitutionName == 'ABC Hospital' then
Data.Storage='MAG2'

print('------ testing an SQL statement --------')
print ('Hospital Name is :'..Data.InstitutionName);
print ('Study Instance Saved is :'..Data.StudyInstanceUID);
print ('*****************************************************');
print ('**********Start of Sql Statement***********************');
print ('******************************************************');
sql("UPDATE DICOMSTUDIES SET HOSPID= 'ABCH' where dicomstudies.StudyInsta='Data.StudyInstanceUID'");
print ('******************SUCCESS************************************');
--sql(format("UPDATE dicomstudies SET Data['0009,1234']='ABCCH' where dicomstudies.StudyInsta='%s', Data.StudyInstanceUID));

end

Records are not updated and I get no errors but as all statements are executed. Please guide me.
--HM

Thanks Marcel.... I will test and update you..

Hi

I had created a new column HOSPCODE in database table name DICOMSTUDIES. Now i want to set the value of HOSPCODE on the basis of Hospital Name. My entry in dicom.ini file is as below:-

[lua]
global = print ('hello world');

ImportConverter0 = if Data.InstitutionName == 'ABC Children Hospital' then Data.Storage='MAG2' and set HCODE to "ABCCH" and Data.Modality == 'CT' then Data:Compress('jk') end;

or i should write each separate importconvertor like this.

[lua]
global = print ('hello world');

ImportConverter0 = if Data.InstitutionName == 'ABC Children Hospital' then Data.Storage='MAG2' end;
ImportConvertor1 = if Data.InstitutionName == 'ABC Children Hospital' then set HCODE to "ABCCH" end;
ImportConvertor2 = if Data.InstitutionName == 'ABC Children Hospital' and Data.Modality == 'CT' then Data:Compress('jk') end;

In this way i uses 3 Importconvertors to perform the same task and i want to avoid this due to the limitation of Importconvertor (i.e Importconvertor 1 to 99). Please guide me how can i use nested IF statements in lua.

Standard Nightly Cleanup comes in action when enabled and disk threshold level is reached.

If i go with the option 1, i uses the dgate command deletestudy and study date???
