NAME

gdcmdump - .TH "gdcmdump" 1 "Fri Oct 29 2010" "Version 2.0.16" "GDCM"

NAME

gdcmdump - .SH "SYNOPSIS"

gdcmdump [options] dcm_file
gdcmdump [options] dcm_directory

DESCRIPTION

The gdcmdump command line program dumps a DICOM file to the console. For those familiary with dcmdump 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

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).
  -A --asn1      print encapsulated ASN1 structure >(0400,0520).

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.

Eg.:

Print Private Attributes

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

SIEMENS CSA Header

Using this option it is possible to dump as a readable text what is contained in the private attribute as found in typical SIEMENS MR DICOM file.

Eg.:

$ gdcmdump --csa MR_SIEMENS_forceLoad29-1010_29-1020.dcm

GEMS Protocol Data Block

Using this option it is possible to dump as a readable text what is contained in the private attribute as found in typical GEMS MR DICOM file.

Protocol Data Block : 0025,xx1b,GEMS_SERS_01

$ gdcmdump --pdb GE_MR_0025xx1bProtocolDataBlock.dcm

Encapsulated ASN1 Structure

This option is mainly used for dumping the ASN1 structure of the encrypted Attribute (0040,0520)

$ gdcmdump encrypted.dcm
