Sorry, but are you talking about wado-rs?

Only to you know, the image with pat id: 0009703828 (HEAD EXP2) from conquest github folder

is not showing in ohif latest version.

Is these params, level and function of queryfunctions correct to wado-rs, in the code below?

/*-------------------------Retrieve DICOM objects (WADO-RS)--------------------------------

/studies/{study}

-----------------------------------------------------------------------------------------*/

router.get("/rs/studies/:study", async (req, res) => {

const StudyInstanceUID = req.params.study;

const query = url.parse(req.url, true).query;

let params = { QueryRetrieveLevel: "SERIES", StudyInstanceUID };

const tparams = getParams(params, tags, query);

params = JSON.stringify(tparams);

...

const cmd = `--dolua:dofile([[${APIFOLDER}/queryfunctions.lua]]);series([[${CQAE}]],[[${params}]],[[${dicomweb}]])`;

....

});

/*-------------------------Retrieve DICOM objects (WADO-RS)--------------------------------

/studies/{study}/series/{series}

-----------------------------------------------------------------------------------------*/

router.get(

"/rs/studies/:studyInstanceUid/series/:seriesInstanceUid",

async (req, res) => {

const query = url.parse(req.url, true).query;

const StudyInstanceUID = req.params.studyInstanceUid;

const SeriesInstanceUID = req.params.seriesInstanceUid;

let params = {

QueryRetrieveLevel: "IMAGE",

StudyInstanceUID,

SeriesInstanceUID,

SOPInstanceUID,

};

....

const cmd = `--dolua:dofile([[${APIFOLDER}/queryfunctions.lua]]);images([[${CQAE}]],[[${params}]],[[${dicomweb}]])`;

/*-------------------------Retrieve DICOM objects (WADO-RS)--------------------------------

/studies/{study}/series/{series}/instances/{instance}

-----------------------------------------------------------------------------------------*/

router.get(

"/rs/studies/:studyInstanceUid/series/:seriesInstanceUid/instances/:sopInstanceUid",

async (req, res) => {

const query = url.parse(req.url, true).query;

const StudyInstanceUID = req.params.studyInstanceUid;

const SeriesInstanceUID = req.params.seriesInstanceUid;

const SOPInstanceUID = req.params.sopInstanceUid;

let params = {

QueryRetrieveLevel: "IMAGE",

StudyInstanceUID,

SeriesInstanceUID,

SOPInstanceUID,

};

....

const cmd = `--dolua:dofile([[${APIFOLDER}/queryfunctions.lua]]);images([[${CQAE}]],[[${params}]],[[${dicomweb}]])`;

....

);

Hi,

I think weasis is using QIDO retrieve that is not implemented. We switched OHIF to wadouri, can you do the same with weasis?

Not implemented yet in QIDO:

thumbnail

instances/{uid}

Hi, Marcel,

A basic beginner doubt.

What means the term "Instance" in dicom. I have used as if it were the dicom image.

For sample. In this text from docs, from wado-rs, it says:

"10.4.1.1 Target Resources

10.4.1.1.1 Instance Resources

Instance Resources (defined in Table 10.4.1-1 are used to retrieve Instances.

Retrieving a Series Instances resource retrieves all the individual Instances contained in the Series. Retrieving a Study Instances resource retrieves all the individual Instances contained in all the Series."

Hi, Marcel

Here is:

conquest_dicom_vue_clientV5.zip

conquest_server_qido_wado_apiV5.zip

I will do

Great. I'm out for some time. I will test ASAP

Kkkkkk. Update your node to latest LTS.

Your node is ancient

Do you mean ohif source code?

If yes, don´t use npm.

Use yarn (https://classic.yarnpkg.com/la…s/install/#windows-stable)

After install yarn do: "yarn install" and after "yarn dev"

I tried compile with npm and didn't works.

The ohif config is into: ...ohif\Viewers\platform\viewer\public\config\default.js

I am testing with this config:

dicomWeb: [
      {
        name: 'CONQUESTSRV1',
        wadoUriRoot: 'http://localhost:3002/api/dicom/wadouri',
        qidoRoot: 'http://localhost:3002/api/dicom/rs',
        wadoRoot: 'http://localhost:3002/api/dicom/rs',
        qidoSupportsIncludeField: true,
        imageRendering: 'wadouri',
        thumbnailRendering: 'wadouri',
        enableStudyLazyLoad: false,
        supportsFuzzyMatching: false,
      },
    ],

I am comparing with the ohif online demo in https://v3-demo.ohif.org

But I didn't find anything wrong

I believe some tag is not found

Here is the functions you posted.

You see something causing it in the code since one works(but show only one serie) and the other doesn't?

// works
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;
  
// doesn't work
    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;

You want test with the latest source code, just download it.

Do "yarn install" and "yarn dev"

Ok, But I needed to use dev mode to looking at the ohif source why it don´t work.

But the source code is complicated.

And it uses react. I´m not a specialist in react.

I use vuejs.

I tried dgate 32 and 64. The latest metadata function doesn´t work with OHIF.

I am using OHIF latest version executing in dev mode

I updated only dgate 32bits

Can you post your complete queryfunctions.lua file?

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

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