Desktop Viewer
The viewer requests a list of certificate signatures from the server. If no list is provided, the viewer uses an internal list of signatures.
The viewer’s resource file has been updated to include Hungarian-language text as of viewer build
Advances in iCAD’s ProFound AI CAD objects have been incorporated into the viewer’s mammo features, including displaying the case score in the CAD header, displaying the case score as a percentage when defined as such, cross-correlating CAD findings in tomo series on 2D images, and updated representational graphics.
The stack ruler graphics used to identify DeepHealth CAD findings have been modified to indicate suspicion level. The graphics can be displayed in color if the color is specified in the CAD object. Color can be disabled from the Use color for CAD markers setting in Options/Presentation States/Mammography CAD SR.
When the scanner includes an estimated detector magnification factor, distance source to patient, or distance source to detector value and the imager pixel spacing value in an image object, the viewer will apply them when calculating linear distances if the Use Estimated Radiographic Magnification Factor setting in the Options/Images/Pixel Spacing panel is enabled. When not defined by the scanner, the defined pixel spacing values are used.
The ability to specify the user ID and password included in the XML file dropped when one is dropped has been extended to all reporting options, including external reporting systems configured using the generic XML file drop. The configuration fields are available in the External Reporting panel in the viewer settings tool.
The copyright year has been updated on the About panel.
Viewer access to the stream server is authenticated using the session ID.
To account for missing log data in the viewer logs, the logging tool has been overhauled. Improvements include adding error messages when logs could not be attached and sent to the server.
The spine label configuration panel has been updated to use an Evolution-style panel. All settings and features remain available.
The Hounsfield annotation tool includes the maximum pixel value contained within the ROI. By default, this value is included, along with the mean and standard deviation. All three values can be disabled by default for each modality type from the Annotations configuration settings panel. They can be shown/hidden for a specific image from the annotation tool’s context menu.
Some popup panels or configuration windows containing data tables did not include column headers to identify the associated data values. These have all been updated to include column headers.
The viewer configuration data file and structure have been overhauled. All existing settings remain available. The default configuration file contents use the resource values specified in the viewer resource file. This file is maintained and distributed in each build. A GUI tool are available from the browser to copy viewer profile settings between the system default, group and individual user accounts. These settings labels use the same value in both the viewer and web page.
DEPENDENCY NOTICE: This change requires medsrv 9.0.5.1 or later.
Under very specific and unlikely conditions, the compression algorithm could encounter a matrix boundary condition that caused the compression effort to fail, resulting in no processed image.
The advanced viewer settings are stored in the user’s profile settings and in the default profile file. Workstation-specific settings such as DICOM image tagging, cache settings and prefetch settings remain stored locally.
The zoom mode setting (Tools/Settings/Images/Zoom) now offers modality-specific options. Modality-independent settings have been moved to their own setting page. These additional pages are Image snapping, Magic glass and Mammography view.
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.
DEPENDENCY NOTICE: Dependencies exist. See details below.
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.
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.
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.
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.

The herpa download uses streaming through the stream server rather than
HTTP from the application server.

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.
The UDI displayed in the viewer details panel has been set to 0086699400025590.
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.
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.
The series matching feature used by the hanging protocol manager and for series grouping has been optimized for performance, removing unnecessary calculations as well.
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.
