DCDUMP(1)					      DICOM PS3 - Describe DICOM file content						 DCDUMP(1)

NAME

       dcdump - ACR/NEMA DICOM PS3 ... DICOM PS3 - Describe DICOM file content

SYNOPSIS

       dcdump [ -v|verbose ] [ -filename ]

DESCRIPTION

       dcdump  reads  the named dicom or acr-nema input file and describes the information contained, attempting to interpret the structure of the
       message, including nested sequences (cf. andump).

       The group and element number, dictionary and explicit value representation, description of tag, value length and value of the  element  are
       displayed, optionally with an offset byte count from the start of the file.

OPTIONS

       The attribute values, description and verbose output go to standard error.

       Binary  attributes are written in hexadecimal with a preceding "0x". Numeric string attributes are written in decimal. Attribute values are
       displayed in hexadecimal or string format as determined by the value representation.

       The basic input switches are described in dcintro(1). Options specific to this program are:

       -verbose
	      Display byte offset from file start and message start, in hexadecimal, and dump contents while reading and once read.

       -filename
	      Show the name of the file supplied in the arguments; a hyphen will be reported if no filename was supplied.
