NAME
dcmdump - Dump DICOM file and data setSYNOPSIS
dcmdump [options] dcmfile-in...
DESCRIPTION
The dcmdump utility dumps the contents of a DICOM file (file format or raw data set) to stdout in textual form. Attributes with very large value fields (e.g. pixel data) can be described as '(not loaded)'. String value fields will be delimited with square brackets ([]). Known UIDs will be displayed by their names prefixed by an equals sign (e.g. '=MRImageStorage'). Empty value fields are described as '(no value available)'.
If dcmdump reads a raw data set (DICOM data without a file format meta-header) it will attempt to guess the transfer syntax by examining the first few bytes of the file. It is not always possible to correctly guess the transfer syntax and it is better to convert a data set to a file format whenever possible (using the dcmconv utility). It is also possible to use the -f and -t[ieb] options to force dcmdump to read a dataset with a particular transfer syntax.

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 dcmdump 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.
