Showing only 100 patients to avoid performance issue.

I got this warning from my Orthan explorer and I can’t see all my patients, but if I use another viewer I am able to see the patient that I looking for. This is the error: "This is a large Orthanc server. Showing only 100 patients to avoid performance issue. Make sure to use lookup if targeting specific patients! " for another hand I am not able to see the videos that US machine sent me, just picture but not de videos for example for ECHOs.

Please carefully read this FAQ in the Orthanc Book:

As can be read, paging is not supported in the low-level Orthanc Explorer interface, but you can contribute to the Orthanc project by creating a plugin or a higher-level Web interface.

You can also simply use the lookup on the welcome screen of Orthanc Explorer.

for another hand I am not able to see the videos that US machine sent me, just picture but not de videos for example for ECHOs.

For US, the Orthanc Web viewer will only display multiframe cine images (use the wheel of the mouse to navigate between frames). If you need to display a MPEG2 or MPEG-4 video embedded in DICOM, please contribute to the Orthanc project by creating a plugin to display such videos:
