The problem

Building one or two tools on top of Cornerstone.js is not that difficult. However, as the number of tools grow, you begin to encounter difficult problems:

  • Tools should behave and be configurable in a consistant way
  • Managing tools across multiple cornerstone enabled elements
  • Tools that need knowledge of a fellow tool's state
  • The ability to "drop-in" others' tools, and they "just work"
  • and many others

This library attempts to solve these problems, and in a highly pluggable and extensible way.

This solution

cornerstone-tools is a light-weight solution for building Tools on top of Cornerstone.js. It's only dependencies are libraries within the Cornerstone family. Instead of trying to "do everything" it aims to be extensible and pluggable to aid in the rapid development of new tools. Ideally, tools created using cornerstone-tools can be easily shared, allowing for the creation of a broader ecosystem.

Example

Below is a simplified example of creating a tool by extending cornerstone-tool's BaseTool class.

import cornerstone from 'cornerstone-core';
import { BaseTool } from 'cornerstone-tools';
import basicLevelingStrategy from '...';
 
export default class WwwcTool extends BaseTool {
  constructor(configuration = {}) {
    const defaultConfig = {
      name: 'Wwwc',
      strategies: { basicLevelingStrategy },
      supportedInteractionTypes: ['Mouse', 'Touch'],
      configuration: {
        orientation: 0,
      },
    };
    const initialConfiguration = Object.assign(defaultConfig, configuration);
 
    super(initialConfiguration);
  }
 
  mouseDragCallback(evt) {
    this.applyActiveStrategy(evt);
 
    cornerstone.setViewport(evt.detail.element, evt.detail.viewport);
  }
 
  touchDragCallback(evt) {
    evt.stopImmediatePropagation();
    this.applyActiveStrategy(evt);
 
    cornerstone.setViewport(evt.detail.element, evt.detail.viewport);
  }
}

Installation

This module is distributed via npm which is bundled with node and should be installed as one of your project's dependencies:

npm install --save cornerstone-tools

This library has peerDependencies listings for:

  • hammerjs - Better touch support
  • cornerstone-core
  • cornerstone-math - Simplifies and provides shared complex tool math logic
  • Any Cornerstone "Image Loader"
    • cornerstone-web-image-loader - JPEG/PNG images
    • cornerstone-wado-image-loader - DICOM images; also parses tags for tool use

If you need to support the IE11 Browser, you will need to provide polyfills as needed.

Setting up and configuring cornerstone-tools's depency can be the biggest hurdle to getting started. Be sure to check out our docs for assistance.
