Hello everyone, I am using orthancteam docker image version version 25.5.1 and OHIF as the viewer. I have been sending MPR images already recostructed by the modality machine to the backend. The problem I have is when now scrolling in the viewer, the UI indicates ‘loading’ but then takes a very long time to load sometimes never.
this is what i have in the orthanc configuration options
“DicomWeb”: {
“Enable”: true,
“Root” : “/dicom-web/”,
“EnableWado” : true,
“WadoRoot” : “/pacs/wado”,
“StudiesMetadata” : “Full”,
“SeriesMetadata” : “Full”,
“EnableMetadataCache”: true,
“MetadataWorkerThreadsCount”: 4
},
and for ohif configuration is as:
window.config = {
extensions: ,
modes: ,
maxNumberOfWebWorkers: 3,
showLoadingIndicator: true,
omitQuotationForMultipartRequest: true,
showWarningMessageForCrossOrigin: false,
useSharedArrayBuffer: “TRUE”,
showPatientInfo: ‘visible’,
investigationalUseDialog: {option:“never”},
strictZSpacingForVolumeViewport: true,
maxNumRequests: {
interaction: 100,
thumbnail: 75,
// Prefetch number is dependent on the http protocol. For http 2 or
// above, the number of requests can be go a lot higher.
prefetch: 25,
},
dataSources: [
{
friendlyName: ‘Orthanc local’,
namespace: ‘@ohif/extension-default.dataSourcesModule.dicomweb’,
sourceName: ‘dicomweb’,
configuration: {
name: ‘dicomweb’,
wadoUriRoot: ‘/pacs/wado’,
qidoRoot: ‘/dicom-web/’,
wadoRoot: ‘/dicom-web/’,
qidoSupportsIncludeField: true,
supportsReject: true,
imageRendering: ‘wadors’,
thumbnailRendering: ‘wadors’,
enableStudyLazyLoad: true,
supportsFuzzyMatching: true,
supportsWildcard: true,
singlepart: ‘bulkdata,video,pdf’,
acceptHeader: [ ‘multipart/related; type=application/octet-stream; transfer-syntax=*’],
useBulkURI: false,
},
}],
defaultDataSource: ‘dicomweb’,
};
how do i go about modifying inorder to improve the load speed in the OHIF viewer? Thanks in advance.
