dcmjs

Overview

dcmjs is a javascript cross-compilation of dcmtk (dcmtk.org) for use in a javascript environment. Uses emscripten.

See http://dcmjs.org

See License.txt for information on using and contributing.

This package is intended for use in browser environments. For server side use probably you want to call to the corresponding natively compiled dcmtk executables.

Usage

The module dcmjs allows to selectively execute a dcmtk application.

• To list available application:

require('dcmjs').run(['list'])

$ node dcmjs-cli list

Output:

dcm2pnm
dcmdump
dcm2xml
dcmftest

• To execute an application:

require('dcmjs').run(['dcmdump'])

$ node dcmjs-cli dcmdump

Output:

$dcmtk: dcmdump v3.6.1 DEV $

dcmdump: Dump DICOM file and data set
usage: dcmdump [options] dcmfile-in...

parameters:
  dcmfile-in                    DICOM input file or directory to be dumped
[...]

• Notes:

  • Node executables can access the local file system. Read here for more details.

  • To use dcmjs on a browser see the demos at http://dcmjs.org/

  • To learn how to use dcmjs from javascript, see javascripts/utils.js and dump/index.html

Prerequisites

• Install Git: http://git-scm.com/downloads

• Install Docker: https://docs.docker.com/engine/installation/

• Install dockcross-web-wasm:

docker pull dockcross/web-wasm
docker run dockcross/web-wasm > ~/bin/dockcross-web-wasm
chmod u+x ~/bin/dockcross-web-wasm

For more details, see https://github.com/dockcross/dockcross#readme

Building

The following commands will checkout dcmjs project and build dcmjs.js using dockcross-web-wasm.

git clone git://github.com/commontk/dcmjs
cd dcmjs
dockcross-web-wasm cmake -Bdcmjs-build -H. -GNinja
dockcross-web-wasm ninja -Cdcmjs-build

When done, you will have these files in the dcmjs-build/dcmjs-build/bin folder:

$ ls -1 dcmjs-build/dcmjs-build/bin/
dcmjs-cli
dcmjs.js
dcmjs.js.gz
dcmjs.wasm
dcmjs.wasmt

File IO using node

To support using the javascript module with node, the current folder is mounted as /working. This means that input files must be in in the current directory or a sub-directory.

For example, assuming we have the these files:

/home/awesome/downloads/dcmjs-cli
/home/awesome/downloads/dcmjs.js
/tmp/data/sr.dcm

The following is expected to work:

cd /tmp
node /home/awesome/downloads/dcmjs-cli dsr2xml /working/data/sr.dcm

Add / Remove applications
