or http://localhost:3002/api/dico…tudyInstanceUIDs/metadata

depending on settings

I guess we can send the entire object as easiest fix. Or delete the pixeldata:

x:Load(....)

x.PixelData = nil

Marcel,

The first metadata searched is from studies and after, series. It´s not from instances.

Here is a metadata from

https://server.dcmjs.org/dcm4c…8695661986996009/metadata

Is possible get it from conquest?

Another problem is you are returning tags in lowercase as

'0020000d' and OHIF doesn't like that. It needs '0020000D'

Code

I did a test changing the tags from lowercase to uppercase and I can get the studies.

But I can't get thumbs for now.

marcelvanherk · Aug 16th 2022

Hi,

we need to implement metadata, e.g. as follows in Lua (study level only for now)

Code

function remotemetadata(ae, level, st)
local remotecode =
[[
local ae=']]..ae..[[';
local level=']]..level..[[';
local dicomweb=]]..tostring(isdicomweb)..[[;
local q2=DicomObject:new();
q2.QueryRetrieveLevel='IMAGE'
q2.StudyInstanceUID=']]..st..[['
q2.SOPInstanceUID=''
local r = dicomquery(ae, 'IMAGE', q2)
local d = DicomObject:new()
d:Read(':'..r[0].SOPInstanceUID)
r = d:Serialize(true,false,true)
local s=tempfile('txt') local f=io.open(s, "wb") f:write(r) returnfile=s f:close()
]]
local f = servercommand('lua:'..remotecode)
return f
end;


function metadata(server, st)
local ae = server or servercommand('get_param:MyACRNema')
b=remotemetadata(ae, 'STUDY', st);
io.write(b)
end

This requires a fix in dgate64.exe; sequences are not properly serialised in dicomweb format throwing the parser later.

Then I get one step further, but OHIF fails to pass StudyInstanceUID from the browser, and SeriesInstanceUID in the viewer.

Marcel

Fixed the bug in dgate.exe

Marcel

marcelvanherk · Aug 16th 2022

This what I get for the WADO request:

Code

http://127.0.0.1/api/dicom/wadouri?requestType=WADO&studyUID=1.2.826.0.1.52132.298498737761445842638386012988770619979&seriesUID=undefined&objectUID=1.2.826.0.1.52132.106253457334200129843823671565739706880&contentType=application/dicom&transferSyntax=*

Somehow the seriesUID is lost

Marcel

jweste · Aug 16th 2022

The Ohif problem with studyinstanceuid is because a tag is in lowercase. I used tag in hexa uppercase and it works

marcelvanherk · Aug 16th 2022

That works but my simplistic metadata only shows one image. Dgate.exe updated on github

marcelvanherk · Aug 16th 2022

This metadata works:

Code

function remotemetadata(ae, level, st)
  local remotecode = 
[[
  local ae=']]..ae..[[';
  local level=']]..level..[[';
  local dicomweb=]]..tostring(isdicomweb)..[[;
  local q2=DicomObject:new();
  q2.QueryRetrieveLevel='IMAGE'
  q2.SeriesInstanceUID=''
  q2.StudyInstanceUID=']]..st..[['
  q2.Rows=''
  q2.Colums=''
  q2.PatientID=''
  q2.PatientName=''
  q2.SOPInstanceUID=''
  q2.InstanceNumber=''
  local r = dicomquery(ae, 'IMAGE', q2)
  r = r:Serialize(true,false,true)
  local s=tempfile('txt') local f=io.open(s, "wb") f:write(r) returnfile=s f:close()
]]
 local f = servercommand('lua:'..remotecode)
 return f
end;

Where do you get rid of the .data in your code?

Marcel

jweste · Aug 16th 2022

Here is

Code

[attach=992][/attach]

jweste · Aug 16th 2022

How do you managed to show all series?

marcelvanherk · Aug 16th 2022

Using the metadata function from above (just edited)

And does the .data thing affect the app at all?

Marcel

The last metadata function is broken to me.

>> And does the .data thing affect the app at all?

Yes. I will have to change the app after we solve the ohif problem

Luiz

jweste · Aug 16th 2022

The latest metadata function, there is an error in browser console and the image is not loading

this one works for me:

 local f = servercommand('lua:'..remotecode)

To me the loading is stucked. The first function works, but load only one serie.

Can you post your complete queryfunctions.lua file?
