New Features and Enhancements

Viewer Build 4

Track cache blob changes during viewer session

DEPENDENCY NOTICE: This feature requires medsrv-9.0.4.

When the contents of a blob in global cache changes, the viewer gets notified so it can decide whether or not to reload the image data.

Viewer Build 3

DEPENDENCY NOTICE: Dependencies exist. See details below.

Support opening non-cached ("uncooked") studies in the desktop viewer

DEPENDENCY NOTICE: This feature requires medsrv-9.0.3.0

When a user opens an unprocessed (ie, uncooked) study in the main viewer, whether it’s initiated from the worklist or WMI client, or when it’s by itself or part of a collection (ie, group open), the viewer notifies the user that the data is unavailable and being created on-the-fly. If the user doesn’t want to wait, he/she has the option to terminate the session. When the information is fully available, the viewer is automatically updated and the study data is displayed.

Apply viewed state to grouped thumbnails

The viewed state icon used in the thumbnail panel to identify series with unviewed images has been extended to grouped series thumbnails. When displayed, at least one image in one of the series in the group has not been rendered in an image frame. Additionally, the in-grid icon indicating the series is currently loaded into an image frame has been extended to grouped series thumbnails. When displayed, at least one series in the series group is loaded into an image frame. In both cases, expand the series group to identify the affected series.

Viewer profile checksum

The viewer adds a checksum to the profile when saving it and the server calculates a checksum and assures it matches the submitted checksum before it overwrites the saved profile. When the viewer requests the checksum from the server for validation, the server sends the calculated checksum.

Restore viewer profile from backup

Users can manage backed up viewer profiles and overwrite the applied viewer profile with a backup from the saved profile panel, accessible from the Manage Backed-up Profiles item in the default Session menu.

Viewer Build 2

DEPENDENCY NOTICE: Dependencies exist. See details below.

Herpa streaming

DEPENDENCY NOTICE: This feature requires medsrv-9.0.2.
The herpa download uses streaming through the stream server rather than HTTP from the application server.

Incorporate gwav4 compression

DEPENDENCY NOTICE: This feature requires medsrv-9.0.2.
The streaming technology has added support for gwav version 4, permitting better initial quality from smaller thumbnail images. The viewer still accepts gwav3 and gwav1, if offered by the server.

Viewer Build 1

UDI for v9 viewer

The UDI displayed in the viewer details panel has been set to 0086699400025590.

Baseline viewer code base on v8.0

The baseline code base for version 9.0 viewer is viewer-8.0.85, desktopApp-8.0.31 and plugins-8.0.8 and includes the new (v9) caching mechanism (cache into memory, only), optimized image loading and only hyper+ streaming support.

Remove settings for retired features

All configurable settings and visible indications for and about retired features have been removed, including prefetch settings, cache management settings and HTTP-based streaming settings.

Series matching algorithm performance improvement

The series matching feature used by the hanging protocol manager and for series grouping has been optimized for performance, removing unnecessary calculations as well.

Server provided stream server addresses

The viewer uses the stream server assigned by the server when streaming data during the session. If no stream server is provided, the viewer uses the server that sent the session (PBS) data.
