@niivue/dcm2niix

@niivue/dcm2niix is a JavaScript + WASM library for converting DICOM files to nifti. This library is intended to be used in the browser, not in a Node.js environment.

All operations are performed using the WASM build of dcm2niix. The processing takes place in a separate worker thread, so it won't block the main thread in your application.

Usage

The @niivue/dcm2niix JavaScript library offers an object oriented API for working with the dcm2niix CLI. Since dcm2niix is a CLI tool, the API implemented in @niivue/dcm2niix is just a wrapper around the CLI options and arguments.

Example

// assuming you have an html input element to get directories.
// <input type="file" id="fileInput" webkitdirectory multiple>
import { Dcm2niix } from '@niivue/dcm2niix';

const dcm2niix = new Dcm2niix();
// call the init() method to load the wasm before processing any data
await dcm2niix.init();
// fileInput is the id of the input element with options: webkitdirectory and multiple
fileInput.addEventListener('change', async (event) => {
    inputFileList = event.target.files;
});
// inputFileList is the value from the input element with options: webkitdirectory and multiple
const resultFileList = await dcm2niix.input(inputFileList).run()  
console.log(resultFileList);
// Do something with the resultFileList (normal browser File Objects)
// perhaps view them with @niivue/niivue :)
