Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Lightweight DICOMweb Server with CouchDB

Note: this is a work in progress and not intended for production or clinical use.

More background information can found in https://na-mic.github.io/ProjectWeek/PW30_2019_GranCanaria/Projects/DICOMweb-CouchDB/

By default, the authentication is none and the application mode is development. You can change the authentication method by changing the auth attribute in config/development.js The value you put in should be the name of a json file in the config directory. A sample config for authentication should have the following information

{ "realm": "your-realm", "authServerUrl": "your-auth-server-port-and-port", "clientId": "your-client-id", "clientSecret": "your-secret" }

Installation

git clone git://github.com/dcmjs-org/dicomweb-server

cd dicomweb-server
npm install

Install CouchDB.

Initially your CouchDB database starts empty, but dicomweb-server will set up the internal database and design documents so there is no need to configure it.

You can run tests by running npm test.

Running

Be sure to have CouchDB running at localhost:5984 (the default), then start the dicomweb-server:

npm start

Usage

The server should be ultimately compatible with any DICOMweb client library.

We test with a Python implementation dicomweb_client.

Get study list:

dicomweb_client --url http://localhost:5985 search studies

Store a DATA_DIRECTORY of DICOM image files (here with the ".IMA" extension). Adjust the command line to match the location and naming of your files. (The -n25 option to xargs is for batching files, leading to fewer calls and thus less overhead.)

find DATA_DIRECTORY -iname \*.IMA -print0 | xargs -0 -n25 dicomweb_client --url http://localhost:5985 store instances

Use with a viewer

It's possible to use this server as a backend to the OHIF Viewer using a configuration like this.

     const dicomweb_serverConfig = {
        routerBasename: "/ohif",
        rootUrl: "http://localhost:2016/ohif",
        servers: {
          "dicomWeb": [
            {
              "name": "dicomweb_server",
              "wadoUriRoot": "http://localhost:5985",
              "qidoRoot": "http://localhost:5985",
              "wadoRoot": "http://localhost:5985",
              "qidoSupportsIncludeField": true,
              "imageRendering": "wadouri",
              "thumbnailRendering": "wadors",
              "requestOptions": {
                  "requestFromBrowser": true
              }
            },
          ]
        }
      };

Note that currently the imageRendering option must be wadouri
