NAME
       drtdump - Dump DICOM RT file and data set


SYNOPSIS
       drtdump [options] drtfile-in...

DESCRIPTION
       The  drtdump  utility  dumps  the contents of a DICOM Radiation Therapy
       (RT) object (file format or raw data set) to stdout  in  textual  form.
       The  output  consists  of  essential  information on the RT object in a
       format that is probably easier to read than the more generic  one  from
       dcmdump.

       If drtdump reads a raw data set (DICOM data without a file format meta-
       header)  it  will attempt to guess the transfer syntax by examining the
       first few bytes of the file. It is not  always  possible  to  correctly
       guess  the  transfer syntax and it is better to convert a data set to a
       file format whenever possible (using the dcmconv utility). It  is  also
       possible  to  use the -f and -t[ieb] options to force drtdump to read a
       dataset with a particular transfer syntax.

LOGGING
       The level of logging output of  the  various  command  line  tools  and
       underlying  libraries  can  be  specified by the user. By default, only
       errors and warnings are written to the  standard  error  stream.  Using
       option  --verbose  also  informational messages like processing details
       are reported. Option --debug can be used to get  more  details  on  the
       internal  activity,  e.g.  for debugging purposes. Other logging levels
       can be selected using option --log-level. In --quiet  mode  only  fatal
       errors  are reported. In such very severe error events, the application
       will usually terminate. For  more  details  on  the  different  logging
       levels, see documentation of module 'oflog'.

       In  case  the logging output should be written to file (optionally with
       logfile rotation), to syslog (Unix) or the event log  (Windows)  option
       --log-config  can  be  used.  This  configuration  file also allows for
       directing only certain messages to a particular output stream  and  for
       filtering  certain  messages  based  on the module or application where
       they are generated.  An  example  configuration  file  is  provided  in
       <etcdir>/logger.cfg.

COMMAND LINE
       All  command  line  tools  use  the  following notation for parameters:
       square brackets enclose optional  values  (0-1),  three  trailing  dots
       indicate  that multiple values are allowed (1-n), a combination of both
       means 0 to n values.

       Command line options are distinguished from parameters by a leading '+'
       or '-' sign, respectively. Usually, order and position of command  line
       options  are  arbitrary  (i.e.  they  can appear anywhere). However, if
       options are mutually exclusive the rightmost appearance is  used.  This
       behavior  conforms  to  the  standard  evaluation  rules of common Unix
       shells.

       In addition, one or more command files can be specified  using  an  '@'
       sign  as  a  prefix to the filename (e.g. @command.txt). Such a command
       argument is replaced by the content  of  the  corresponding  text  file
       (multiple  whitespaces  are  treated  as a single separator unless they
       appear between two quotation marks) prior to  any  further  evaluation.
       Please  note  that  a command file cannot contain another command file.
       This simple but effective  approach  allows  one  to  summarize  common
       combinations  of  options/parameters  and  avoids longish and confusing
       command lines (an example is provided in file <datadir>/dumppat.txt).

ENVIRONMENT
       The drtdump utility  will  attempt  to  load  DICOM  data  dictionaries
       specified  in the DCMDICTPATH environment variable. By default, i.e. if
       the  DCMDICTPATH  environment   variable   is   not   set,   the   file
       <datadir>/dicom.dic  will be loaded unless the dictionary is built into
       the application (default for Windows).

       The  default  behavior  should  be  preferred   and   the   DCMDICTPATH
       environment  variable  only used when alternative data dictionaries are
       required. The DCMDICTPATH environment variable has the same  format  as
       the  Unix  shell PATH variable in that a colon (':') separates entries.
       On Windows systems, a semicolon (';') is used as a separator. The  data
       dictionary  code  will  attempt  to  load  each  file  specified in the
       DCMDICTPATH environment variable. It is an error if no data  dictionary
       can be loaded.
