dcmmkcrv: Add 2D curve data to image

SYNOPSIS

dcmmkcrv [options] dcmimg-in curvedata-in dcmimg-out

The dcmmkcrv utility allows to create DICOM images containing curve data. Since curve data is hardly used by vendors today, this is intended as a means to test implementations that can read curve data. The utility reads an existing DICOM image and a text file containing the curve data in textual form. A DICOM curve data repeating group is created according to the options specified on the command line, added to the existing image and written back to file. The output file is encoded with the same transfer syntax used for the input file. This utility only supports the creation of two-dimensional curves.

PARAMETERS

dcmimg-in     DICOM input image file

curvedata-in  curve data input file (text)

dcmimg-out    DICOM output filename

OPTIONS

general options

        print this help text and exit

      --version
        print version information and exit

  -v  --verbose
        verbose mode, print processing details

curve creation options

curve type:

  -r  --poly
        create as POLY curve (default)

  +r  --roi
        create as ROI curve

curve value representation:

  +v  --data-vr  [n]umber: integer 0..4 (default: 4)
        select curve data VR: 0=US, 1=SS, 2=FL, 3=FD, 4=SL

  -c  --curve-vr  [n]umber: integer 0..2 (default: 0)
        select VR with which the Curve Data element is written
        0=VR according to --data-vr, 1=OB, 2=OW

repeating group:

  -g  --group  [n]umber: integer 0..15 (default: 0)
        select repeating group: 0=0x5000, 1=0x5002 etc.

curve description:

  -l  --label  s: string
        set Curve Label to s (default: absent)

  +d  --description  s: string
        set Curve Description to s (default: absent)

  -a  --axis  x: string, y: string
        set Axis Units to x\y (default: absent)

NOTES

Syntax of the Curve Data File

The curve data file is expected to be a plain ASCII text file containing numbers (integer or floating point) comprising the values of the point coordinates. Numbers must be separated by whitespace. No checking of the value range or value range conversion is performed. Example:

 256.451947    1.000000
 477.689863  128.822080
 128.822080  477.689863
  35.310137  128.822080
 256.451947    1.000000

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 behaviour 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) prior to any further evaluation. Please note that a command file cannot contain another command file. This simple but effective approach allows to summarize common combinations of options/parameters and avoids longish and confusing command lines (an example is provided in file share/data/dumppat.txt).

ENVIRONMENT

The dcmmkcrv 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 <PREFIX>/lib/dicom.dic will be loaded unless the dictionary is built into the application (default for Windows).

The default behaviour 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. 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.
