Image Streaming

Streaming Settings	Default	Description
Downloading mechanism	Stream	Sets the image downloading mechanism used by the viewer. Available modes are: - HTTP protocol - Stream - Hybrid rendering (experimental only, do not enable with out eRAD support assistance)
Show stream detailed information	Disabled	Viewer shows detailed information about the stream connection(s), when the mouse is over the stream indicator icon. See Stream Server Status
Stream Logging	Disabled	Detailed logging for streaming communication
Streaming Image Behavior	Show thumbnail	Determines how streaming images behave when they are not downloaded yet

Logging

Logging Settings	Default	Description	File Path	File Base Name
Create log file	Enabled	When enabled, the viewer will create a log file about user activity.	%LOCALAPPDATA%\eRAD PACS Viewer\Logs	log-<yyyy>-<mm>-<dd>--<24hr>-<min>-<sec>.txt
WMI logging	Disabled	When enabled, the viewer will write WMI activity into the log file.	%LOCALAPPDATA%\eRAD PACS Viewer\Logs	log-<yyyy>-<mm>-<dd>--<24hr>-<min>-<sec>.txt
Create crash log	Enabled	If the eRAD PACS viewer crashes, this setting allows the viewer to create a log file to help identify the problem.	%LOCALAPPDATA%\eRAD PACS Viewer\Logs	crashinfo-<yyyy>-<mm>-<dd>--<24hr>-<min>-<sec>.txt
Create net dumps	Enabled	Net dumps are created when the viewer encounters a network problem. As these errors have a tendency to happen multiple times in a row, the corresponding logs usually contain redundant information. Consider disabling net dump sending to preserve server storage and network bandwidth	%LOCALAPPDATA%\eRAD PACS Viewer\Logs	netDump-<yyyy>-<mm>-<dd>--<24hr>-<min>-<sec>.txt
Maximum age of unsent log files (in days)	30	Log files older than the specified age are automatically purged. If set to 0, log files are kept indefinitely.
Maximum age of sent log files (in days)	3	Log files sent to the server are purged if they're older than the maximum age. If set to 0, sent log files are kept indefinitely.
Maximum number of log files	25	If the number of log files in any category (session, crash, net) exceeds the maximum amount, the oldest log is purged. Set to 0 to allow any number of log files. Applied on a per category basis.

General Settings

Hybrid Mode Rendering

NOTE: These settings are for experimental use only and should not be altered without guidance from eRAD personnel.

Hybrid mode rendering	Default	Description
Stream port overriding	-1	Default value (-1) means the viewer will use the port defined on the server for streaming.
Stream secure port overriding	-1	Default value (-1) means the viewer will use the secure port defined on the server for streaming.
Stream packet size	0	Define packet size in bytes. 0 value means auto packet size will be used.
Streamed image base minimum size by ratio	8.000	Minimum first chunk size in relative size of full image.
Streamed image base size in kilobyte	3.000	First chunk size in kilobyte of the minimum resolution image. This chunk has high priority.
Streamed image base resolution	256	Minimum resolution of the image for the first chunk size calculation. If an image is less than this size, the viewer will request the base size of the image.
Streamed image linear factor	1.000	Linear area factor of the first chunk size calculation.
Streamed image exponent factor	1.000	Exponent area factor of the first chunk size calculation.
DICOM only Herpa	Enabled	Configures the viewer to download only the DICOM data and important thumbnails in the Herpa. The viewer will reneder the missing thumbnails from the images.
