# 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 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

      -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.:

    $ gdcmdump GE_DLX-8-MONO2-PrivateSyntax.dcm

### 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

    (0029,0010)siemens csa header
    Image shadow data (0029,xx10)

### 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)
