Package Exports

med-img-reader

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (med-img-reader) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

med-img-reader

Read a dicom series in the browser using ITK series reader. Viewer example

Installation

npm install med-img-reader

Usage example

First things first

const {FS, MedImgReader} = require('med-img-reader');

Example how to get some dicom files and write them in the browser

getDicomFiles(){
    const self = this;

    var series_dir = '/some_dir';

    try{
    //This package uses FS from emscripten, for more information on FS read the documentation at https://emscripten.org/docs/api_reference/Filesystem-API.html
      FS.stat(series_dir);
    }catch(e){
      FS.mkdir(series_dir);
    }
    
    //Use your own mechanism to request the dicom file from your server. You can use 'axios' for example or http from angular etc.
    return self.getDicomBufferSomeHow()
    .then(function(res){
      if(res.data){
        var img_filepath = series_dir + '/mydcmfile';
        try{
          //This will write the dicom file in the FS file system in the browser
          FS.writeFile(img_filepath, new Uint8Array(res.data), { encoding: 'binary' });  
        }catch(e){
          console.error(e);
        }
      }else{
        console.error(res);
      }
    });
}

Example how to read the dicom series

readSeries(series_dir){
    try{
      const medImgReader = new MedImgReader();
      medImgReader.SetDirectory(series_dir);
      medImgReader.ReadDICOMDirectory();    
      return Promise.resolve(medImgReader);
    }catch(e){
      return Promise.reject(e);
    }
}

Example to manipulate the image data

getTheActualImageData(medImgReader) {
    medImgReader.GetOrigin();
      medImgReader.GetSpacing();
    medImgReader.GetImageBuffer();//This is the array with the actual values of the dicom series
    medImgReader.GetNumberOfComponentsPerPixel();
    medImgReader.GetDirection();
    medImgReader.GetDimensions();
