前言

实现一个简单的mpr + vr 功能。
cornerstone3D已经全都实现了，修改为自己的界面。
查看官方示例-cursor3d
cornerstonejs源码位置packages\tools\examples\cursor3D\index.ts
效果如下：
在这里插入图片描述

一、程序结构

1. view3d.vue

包含Toolbar3d.vue组件和DispalyerArea3D.vue组件
Toolbar3d.vue与前面章节中的Toolbar.vue组件一样，主要放置一些操作按钮

2. DisplayerArea3D.vue

包含四个窗口div: axial, sagittal, coronal, vr
cornerstone3D相关的函数全写到mprvr.js中，由DisplayerArea3D.vue调用

3. mprvr.js

实现MPR类，整理了下官方示例-curso3d中的代码，方便调用

二、代码

3. mprvr.js

把官方示例中的代码整理成一个类， MPR

1）init函数

创建toolGroup，管理mpr三个窗口的操作工具，添加工具WindowLevelTool、CrosshairsTool、PanTool、ZoomTool、StackScrollTool
创建vrToolGroup，管理vr窗口操作工具，添加工具TrackballRotateTool、ZoomTool、PanTool
创建renderingEngine
定义mpr三个 ViewportType.ORTHOGRAPHIC类型窗口, 方向分别为：Enums.OrientationAxis.AXIAL，Enums.OrientationAxis.CORONAL，Enums.OrientationAxis.SAGITTAL
定义vr 一个ViewportType.VOLUME_3D类型窗口，方向指定为Enums.OrientationAxis.CORONAL

2）loadImages函数

加载imageIds, 生成volume数据
四个窗口添加到renderingEngine
激活窗口操作工具
绘制窗口，设置vr窗口配色方案

3）getSliceCount, getSliceIndex 函数

获取mpr窗口slice位置，显示在右上角

4） resize函数

窗口尺寸变化时，调用此函数重绘，否则显示的图像比例变形

5） bindRenderEvent, bindCameraEvent

用于绑定cornerstone3D 中的IMAGE_RENDERED, CAMERA_MODIFIED事件
IMAGE_RENDERED发生时调用UpdateText可以绘制四个角落的文字
CAMERA_MODIFIED发生时可能mpr的三个窗口方向发生变化，用于以后更新方位文字

6）destory函数

删除绑定元素，清理缓存

getDicomInfo函数

获取姓名，性别、年龄等信息，显示在窗口右上角
