Hey everyone, I have been working on major improvements to the visual DICOM browser:

What’s New

Performance for large datasets (both remote and local)

Optimized for >100GB databases

Lazy thumbnail generation in background

Use of model/views → batch model updates → less UI flickering and interactive filtering on local database

Better Slicer Integration

New/cleaner UI with visual operation status

Studies auto-sort by date (most recent first)

Smart query prioritization (top 2 studies get high priority)

and bug fixes

See full list in links section below
