DCKEY(1)					       DICOM PS3 - Extract attribute values						  DCKEY(1)

NAME

       dckey - ACR/NEMA DICOM PS3 ... Extract attribute values

SYNOPSIS

       dckey  [  -ignorereaderrors  ] [ -v|verbose ] [ -filename ] [ -describe ] [ -brief ] [ -d|decimal ] [ -key|k  elementname|(0xgggg,0xeeee) ]
		 ...

DESCRIPTION

       dckey reads the named dicom input file and displays the values of the selected attributes.

       Binary attributes are written in hexadecimal with a preceding "0x" and numeric string  attributes  are  written	in  decimal  as  they  are
       encoded, unless the -decimal option is specified.

OPTIONS

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

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

       -describe
	      Display the tag, name, value representation and value length of the attribute.

       -brief
	      Display  the  keyword  of the attribute, and equals sign, and then the value, for use in scripts that automatically extract multiple
	      values in the same dckey invocation. Implies -noerror.

       -ignorereaderrors
	      Attempt to extract key values even if errors encountered whilst parsing DICOM file.

       -noerror
	      Do not report an error if the requested attribute was not found, just an empty value or line. Implied by -brief.

       -d|decimal
	      Display the first (or only) value of a numeric attribute as a decimal value.

       -k|key  elementname|(0xgggg,0xeeee)
	      Add a key to the list of attributes to be extracted. The attribute may  also  be	specified  as  a  hexadecimal  pair  of  the  form
	      (0xgggg,0xeeee), which also allows private attributes to be fetched.

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

       % dckey -key Rows -key Columns -key ImageLocation

       (0x0028,0x0011) US Columns VR=<US> VL=<0x0002> [0x0100]
       Error - Not found - (0x0028,0x0200) US Image Location

       % dckey -k Rows -k ImagePositionPatient
	     -k StudyDate -k StudyTime
	     -k SOPClassUID test.dc3

       0x0200
       % dckey -d -k Rows test.dc3
       512
       % dckey -brief -k Rows -k Columns test.dc3
       Rows=0x200
       Columns=0x200

BUGS

       Attempts to extract sequences or OB,OW attributes may fail nastily.

       The order in which the attributes are extracted and written is not the same order as they are specified on the command line, and should not
       be depended on.

       The -describe and other options cannot be used at the same time.

       The -decimal option uses a double conversion before displaying the value and there may be sign extension and  precision	issues	with  some
       values.

       The  reading  of  the  attributes  from the DICOM file will not proceed past the top level Pixel Data attribute, in order to accelerate the
       speed of reading.
