iQ-VIEW 4.1 now supporting Key Object Selection (KOS)
We are excited to announce the release of iQ-VIEW 4.1 – the latest release of our diagnostic DICOM viewer. This new version includes enhancements for both radiologists and administrators, providing features that aid the diagnostic reading process and offer improved configuration flexibility.
Find out below which features have been added recently.
What’s new in iQ-VIEW 4.1?
For radiologists
- Designation and management of key images
iQ-VIEW now provides full support for creating and managing DICOM Key Object Selection (KOS) documents directly within the viewer. Radiologists can mark and unmark key images with a single interaction, visually identify key images across series, and navigate them efficiently via a dedicated key object viewer. Key images are clearly indicated throughout the UI (thumbnails, scrollbar markers, and series preview), can be reordered via drag-and-drop, and support cross-study references, including prior studies. This enables structured, standards-compliant highlighting of clinically relevant images. - Filter for non-local studies
The status filter in the Network tab of iQ-VIEW has been extended to include non-local studies, allowing radiologists to display studies that exist only on external systems (e.g., remote PACS nodes) and have not yet been downloaded locally. - Enhanced synchronization features
The viewer now offers improved synchronization across multiple tiles, enabling coordinated comparison of images. Slice position, zoom/pan (PRO), and windowing (PRO) can be synchronized to support a more efficient diagnostic workflow. - Better overlay readability
In the Local Settings dialog, radiologists can now easily customize the color of the text overlay in the viewer to suit their preferences. This is particularly useful for improving readability and reducing interpretation errors when working with low-quality or grainy images.
For administrators
- Enhanced “Write each image to a new series” option
The existing server administration option to write each image to a new series, previously limited to US images, has been extended to also support CR, DX, and MG modalities. The supported modalities can be combined freely, or the series splitting behavior can be fully disabled. - Transfer syntax names
The “Preferred transfer syntax (when sending)” combo box in the DICOM settings dialog, which previously displayed only the numeric UID, now also shows a human-readable transfer syntax alias, simplifying identification of the selected syntax. - Configurable default modality for import
Administrators can now configure a default modality for the document import workflow via the iQ-VIEW.ini file. When importing repeatedly from the same modality (e.g., DOC), this removes the need to manually change the modality for each import.
- Improved logging performance and configuration options
Logging in iQ-VIEW has been enhanced to use non-blocking, asynchronous processing, significantly reducing performance impact and improving system responsiveness, even with debug logging enabled. Log file size limits and log rotation behavior are now configurable, allowing better control of disk usage. - Automated overflow cleanup
A new overflow management section in the server administration dialog now allows you to specify a time for the automatic periodic cleanup of locally stored studies without having to restart iQ-VIEW.
