A Horos alternative for editing and anonymizing DICOM files

Horos is a free, open-source DICOM viewer for macOS, with PACS networking and 3D rendering. dcmage does less viewing and more file work: it edits tags, de-identifies studies and records every change, in the browser or as a Mac app. The two can be used side by side.
