gdcmdump - Online in the Cloud

PROGRAM:

NAME

gdcmdump - dumps a DICOM file, it will display the structure and values contained in the
specified DICOM file.

SYNOPSIS

gdcmdump [options] dcm_file
gdcmdump [options] dcm_directory

DESCRIPTION

The gdcmdump command line program dumps a DICOM file to the console. For those familiar
with dcmdump (DCMTK) output, gdcmdump has some minor differences. Namely:

· For Implicit Transfer Syntax gdcmdump will print ?? instead of the dictionary VR

gdcmdump has a limited private dictionary that is used to lookup private element whenever
possible.

PARAMETERS

dcm_file DICOM input filename
dcm_directory DICOM input directory

OPTIONS

specific options
-x --xml-dict generate the XML dict (only private elements for now).
-r --recursive recursive (input is a directory)
-d --dump dump value (limited use).
-p --print print value instead of simply dumping (default).
-c --color print in color.
-C --csa print SIEMENS CSA Header (0029,[12]0,SIEMENS CSA HEADER).
-P --pdb print GEMS Protocol Data Block (0025,1b,GEMS_SERS_01).
--elscint print ELSCINT Protocol Information (01f7,26,ELSCINT1).
--vepro print VEPRO Protocol Information (0055,20,VEPRO VIF 3.0 DATA).
or VEPRO Protocol Information (0055,20,VEPRO VIM 5.0 DATA).
--sds print Philips MR Series Data Storage (1.3.46.670589.11.0.0.12.2) Information (2005,32,Philips MR Imaging DD 002).
-A --asn1 print encapsulated ASN1 structure >(0400,0520).
--map-uid-names map UID to names.

general options
-h --help
print this help text and exit

-v --version
print version information and exit

-V --verbose
verbose mode (warning+error).

-W --warning
warning mode, print warning information

-E --error
error mode, print error information

-D --debug
debug mode, print debug information

special options
-I --ignore-errors dumps even if file is corrupted (advanced users only, see disclaimers).

TYPICAL USAGE

Printing Implicit Transfer Syntax
The VR are not found in the file, thus are presented with a "(??)", and right next to it
(if found) the correct VR.

Print Private Attributes
GDCM has a limited private dictionary. Whenever possible, it will try to lookup the
private data element.
