Comparison of DICOMweb for WSI Between Orthanc & DCM4CHEE

Hi,

I’m hopeful someone can help me out with this challenge. I’ve been attempting to utilize Orthanc as DICOMweb service for OHIF and SLIM viewers. I have both viewers working against a DCM4CHEE service and Orthanc service. The performance difference between Orthanc DICOMweb with WSI Plugin and DCM4CHEE is significant.

I’m using the same images in both (WSI DICOM files from TCIA Imaging Data Commons, even sending from Orthanc to DCM4CHEE. I’ve looked through all the settings I can find for optimizing Orthanc DICOM Web but can’t seem to figure it out. Is this the normal behavior for DICOMweb on WSI DICOM files in Orthanc?

If anyone is willing to look at my settings or provide some suggestions I would love to get Orthanc to work for this. Let me know what files or log output would be most helpful and I will gladly add it to this post.

Hello,

If you don’t provide us with a concrete use case, including sample DICOM instances, we cannot provide any support.

Kind Regards,
Sébastien-
