New in 0.2.0
PACS query and retrieve. Search a DICOM archive by patient, ID, accession, date range or modality, drill into a study’s series, and retrieve just the series you need. The viewer prefers C-GET, which brings images back over the same connection as the query and needs no open port; servers that only support C-MOVE are handled too, with an optional receiver that is off unless you turn it on. Opened series and archived studies can be sent back to a PACS from the save menu or the archive.
Also in this release: automatic anatomy labelling (117 structures on CT, 50 on MR) running entirely on your own machine, and a full segmentation editor with region growing, watershed and surface export.
Verifying the download
Because this build is not yet notarised by Apple, it is worth checking that the file you received is the one published here. In Terminal:
shasum -a 256 ~/Downloads/Neuroin-DICOM-Viewer-0.2.0-macOS-arm64.dmgThe output should match the SHA-256 above exactly. If it does not, delete the file and download it again.
First launch on macOS
This build is not yet notarized by Apple, so the first launch needs one extra step: open the DMG, drag Neuroin DICOM Viewer into Applications, then right-click (or Control-click) the app → Open → Open. Double-clicking the first time shows a “developer cannot be verified” message — that is macOS Gatekeeper’s standard prompt for non-notarized apps, not a problem with the download. After the first launch it opens normally.
