<template>
 <div class="dicom" ref="dicomImage"></div>
</template>
<script>
import * as cornerstone from "cornerstone-core";
import * as dicomParser from "dicom-parser";
// 不建议 npm 安装 cornerstoneWADOImageLoader 如果你做了 会很头疼
let cornerstoneWADOImageLoader = require('../../../static/dist/cornerstoneWADOImageLoader.js')
// import {cornerstoneWADOImageLoader} from "../../../static/dist/cornerstoneWADOImageLoader.js";
//指定要注册加载程序的基石实例
cornerstoneWADOImageLoader.external.cornerstone = cornerstone;
//配置 webWorker (必须配置)
//注意这里的路径问题 如果路径不对 cornerstoneWADOImageLoaderWebWorker 会报错 index.html Uncaught SyntaxError: Unexpected token <
var config = {
 webWorkerPath: "/static/dist/cornerstoneWADOImageLoaderWebWorker.js",
 taskConfiguration: {
 decodeTask: {
  codecsPath: "/static/dist/cornerstoneWADOImageLoaderCodecs.js"
 }
 }
};
cornerstoneWADOImageLoader.webWorkerManager.initialize(config);
export default {
 name: 'previewDicom',
 props: {
  imageId: {
   type: String,
   required: true
  }
 },
 data () {
  return {
  }
 },
 // watch:{
 // imageId(newValue,oldValue){
 //  var url = `wadouri:${this.imageId}`;
 //  this.loadAndViewImage(url);
 // } 
 // },
 mounted() {
  var url = `wadouri:${this.imageId}`;
  this.loadAndViewImage(url);
 },
 methods: {
  loadAndViewImage(imageId) {
   //找到 要放置 Dicom Image 的元素
   // var element = document.getElementById("dicomImage");
   console.log(1334);
   let element = this.$refs.dicomImage
   cornerstone.enable(element)
   // cornerstone.loadAndCacheImage 函数 负责加载图形 需要 图像地址 imageId
   cornerstone.loadAndCacheImage(imageId).then(
    function(image) {
     var viewport = cornerstone.getDefaultViewportForImage(element, image);
     cornerstone.displayImage(element, image, viewport);
    },
    function(err) {
     console.error(err)
    }
   );
  } 
 }
}
</script>
<style scoped>
.dicom{
 height: 100%;
}
</style>

引入组件，注册，使用：

 <div class="son" v-for="(item,key) in dicomList" :key="key" @click="imgClcik(item.url)">
 <preview-dicom :imageId="item.url"></preview-dicom>
 </div>

dicomList:[
  {
   url:'http://127.0.0.1/testDICOM/CTStudy/3.719KB.DCM',
  },
  {
   url:'http://127.0.0.1/testDICOM/CTStudy/3.719KB.DCM',
  },
  {
   url:'http://127.0.0.1/testDICOM/CTStudy/test.dcm',
  },
  {
   url:'http://127.0.0.1/testDICOM/CTStudy/1.5191KB.DCM',
  },
  {
   url:'http://127.0.0.1/testDICOM/CTStudy/1.5191KB.DCM',
