dcmage is a free DICOM workbench for researchers and imaging data teams. Edit nested metadata, apply PS3.15 de-identification profiles, review burned-in text redactions and inspect 3D MPR views. Core imaging processing runs on your device. The browser app at https://app.dcmage.com needs no account; a Mac App Store version is also available. Native Windows is in development. For research, data management and technical review, not diagnosis.
