    DICOM Microscopy Viewer

    Vanilla JS library for web-based visualization of DICOM VL Whole Slide Microscopy Image datasets and derived information.

    The viewer allows visualization of slide microscopy images stored in a DICOMweb compatible archive. It leverages the dicomweb-client JavaScript library to retrieve data from the archive.

    Features

    • Display of different image types: VOLUME/THUMBNAIL, OVERVIEW, LABEL
    • Annotation of regions of interest (ROI) as vector graphics based on 3-dimensional spatial coordinates (SCOORD3D): POINT, MULTIPOINT, POLYLINE, POLYGON, ELLIPSE, ELLIPSOID
    • Assembly of concatenations
    • Decoding of compressed pixel data, supporting baseline JPEG, JPEG 2000, and JPEG-LS codecs
    • Correction of color images using ICC profiles
    • Additive blending and coloring of monochromatic images of multiple optical paths (channels), supporting highly-multiplexed immunofluorescence imaging
    • Overlay of image analysis results in the form of DICOM Segmentation, Parametric Map, Comprehensive 3D SR, or Microscopy Bulk Simple Annotations

    Documentation

    Documentation of the JavaScript Application Programming Interface (API) is available online at herrmannlab.github.io/dicom-microscopy-viewer.

    Getting started

    Note that the dicom-microscopy-viewer package is not a viewer application, it is a library to build viewer applications.

    Below is an example for the most basic usage: a web page that displays a collection of DICOM VL Whole Slide Microscopy Image instances of a digital slide. For more advanced usage, take a look at the Slim viewer.

    Basic usage

    The viewer can be embedded in any website, one only needs to

    • Create an instance of VolumeImageViewer. The constructor requires an instance of DICOMwebClient for retrieving frames from the archive as well as the metadata for each DICOM image as an instance of VLWholeSlideMicroscopyImage.

    • Call the render() method, passing it the HTML element (or the name of the element), which shall contain the viewport.

    import * as DICOMMicroscopyViewer from 'dicom-microscopy-viewer';
    import * as DICOMwebClient from 'dicomweb-client';
    
    // Construct client instance
    const client = new DICOMwebClient.api.DICOMwebClient({
      url: 'http://localhost:8080/dicomweb'
    });
    
    // Retrieve metadata of a series of DICOM VL Whole Slide Microscopy Image instances
    const retrieveOptions = {
      studyInstanceUID: '1.2.3.4',
      seriesInstanceUID: '1.2.3.5'
    };
    client.retrieveSeriesMetadata(retrieveOptions).then((metadata) => {
      // Parse, format, and filter metadata
      const volumeImages = []
      metadata.forEach(m => {
        const image = new DICOMMicroscopyViewer.metadata.VLWholeSlideMicroscopyImage({
          metadata: m
        })
        const imageFlavor = image.ImageType[2]
        if (imageFlavor === 'VOLUME' || imageFlavor === 'THUMBNAIL') {
          volumeImages.push(image)
        }
      })
    
      // Construct viewer instance
      const viewer = new DICOMMicroscopyViewer.viewer.VolumeViewer({
        client,
        metadata: volumeImages
      });
    
      // Render viewer instance in the "viewport" HTML element
      viewer.render({ container: 'viewport' });
    });
