NAME

       dcdirdmp - ACR/NEMA DICOM PS3 ... DICOM PS3 - Describe DICOMDIR content

SYNOPSIS

       dcdirdmp [ -v|verbose|vv|veryverbose ] [ -showrecordinfo ] [ -description ] [ -p|paths ] [
                 -filename ]

DESCRIPTION

       dcdirdmp reads the named dicom input file and interprets it as a DICOMDIR file, that is  a
       DICOM file containing an instance of the Basic Directory IOD.

       If  the file contains a valid instance of the directory, the hierarchical record structure
       is traversed and displayed in a depth first manner. The default output  displays  selected
       attribute  values  for recognized types of directory record, including the Referenced File
       ID. The verbose options increase the amount of information dumped.

       Note that directory record offset values within attributes are in bytes from the start  of
       the  file  (including  meta-information  header  and  pre-amble)  and  these  point to the
       beginning of the Item  delimiter  that  introduces  each  item  in  the  directory  record
       sequence.  The  offset  values  displayed in the verbose output for the first attribute of
       each sequence item will therefore be 8 bytes greater, as the Item delimiter itself is  not
       displayed.

OPTIONS

       The 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:

       -v|verbose
              Display all attributes in each directory record.

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

       -showrecordinfo
              Display byte offset with each directory record entry, in hexadecimal.

       -description
              Display the Study and Series Description attribute values.

       -p|paths
              Show  Unix  style path information for each referenced file only (suppresses normal
              output).  Used, for example, to feed paths as command line arguments to some  other
              utility.

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