NAME

echoscu - DICOM verification (C-ECHO) SCU

SYNOPSIS

 
 echoscu [options] peer port

DESCRIPTION

The echoscu application implements a Service Class User (SCU) for the Verification SOP Class. It sends a DICOM C-ECHO message to a Service Class Provider (SCP) and waits for a response. The application can be used to verify basic DICOM connectivity.

PARAMETERS

 
 peer  hostname of DICOM peer
 
 port  tcp/ip port number of peer

NOTES

DICOM Conformance

The echoscu application supports the following SOP Classes as an SCU: 
 
 VerificationSOPClass                1.2.840.10008.1.1

Unless the --propose-ts option is used, the echoscu application will only propose the transfer syntax

 
 LittleEndianImplicitTransferSyntax  1.2.840.10008.1.2

COMMAND LINE

All command line tools use the following notation for parameters: square brackets enclose optional values (0-1), three trailing dots indicate that multiple values are allowed (1-n), a combination of both means 0 to n values.

Command line options are distinguished from parameters by a leading '+' or '-' sign, respectively. Usually, order and position of command line options are arbitrary (i.e. they can appear anywhere). However, if options are mutually exclusive the rightmost appearance is used. This behaviour conforms to the standard evaluation rules of common Unix shells.

In addition, one or more command files can be specified using an '@' sign as a prefix to the filename (e.g. @command.txt). Such a command argument is replaced by the content of the corresponding text file (multiple whitespaces are treated as a single separator) prior to any further evaluation. Please note that a command file cannot contain another command file. This simple but effective approach allows to summarize common combinations of options/parameters and avoids longish and confusing command lines (an example is provided in file share/data/dumppat.txt).

ENVIRONMENT

The echoscu utility will attempt to load DICOM data dictionaries specified in the DCMDICTPATH environment variable. By default, i.e. if the DCMDICTPATH environment variable is not set, the file <PREFIX>/lib/dicom.dic will be loaded unless the dictionary is built into the application (default for Windows).

The default behaviour should be preferred and the DCMDICTPATH environment variable only used when alternative data dictionaries are required. The DCMDICTPATH environment variable has the same format as the Unix shell PATH variable in that a colon (':') separates entries. The data dictionary code will attempt to load each file specified in the DCMDICTPATH environment variable. It is an error if no data dictionary can be loaded.
