How to import DICOM files

Weasis can open DICOM files from various ways and sources: drag and drop, local device, DICOM ZIP, DICOM CD/DVD, DICOM Query/Retrieve, and from commands locally or remotely.

Note

An popup error message is displayed when DICOM files cannot be read (from v4.3.0) or when a network error occurs. In the latter case a message asking to download again the missing files.
