Question

我想从我的网站上显示Dicom图像。所以我找到了基石库来做到这一点。

这是代码：

<!DOCTYPE HTML>
<html>
<head>
    <!-- twitter bootstrap CSS stylesheet - included to make things pretty, not needed or used by cornerstone -->
    <link href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" rel="stylesheet">

    <link href="cornerstone.min.css" rel="stylesheet">

</head>
<body>
<div class="container">

    <div class="page-header">
        <br>

    </div>

    <div class="row">
        <form class="form-horizontal">
            <div class="form-group">
                <input type="file" id="selectFile" >
            </div>
        </form>
    </div>

    <div style="width:512px;height:512px;position:relative;color: white;display:inline-block;border-style:solid;border-color:black;"
         oncontextmenu="return false"
         class='disable-selection noIbar'
         unselectable='on'
         onselectstart='return false;'
         onmousedown='return false;'>
        <div id="dicomImage"
             style="width:512px;height:512px;top:0px;left:0px; position:absolute">
        </div>
    </div>
</div>
</body>


<!-- jquery - currently a dependency and thus required for using cornerstoneWADOImageLoader -->
<script src="jquery.min.js"></script>

<!-- include the cornerstone library -->
<script src="cornerstone.min.js"></script>

<!-- include the dicomParser library as the WADO image loader depends on it -->
<script src="dicomParser.min.js"></script>

<!-- include the cornerstoneWADOImageLoader library -->
<script src="cornerstoneWADOImageLoader.min.js"></script>
<script src="../dist/cornerstoneFileImageLoader.js"></script>
<!-- jpeg 2000 codec -->
<script src="jpx.min.js"></script>

<script>


    $(document).ready(function() {

        var element = $('#dicomImage').get(0);
         cornerstone.enable(element);

        // Listen for the change event on our input element so we can get the
        // file selected by the user
        $('#selectFile').on('change', function(e) {
            // Add the file to the cornerstoneFileImageLoader and get unique
            // number for that file
            var file = e.target.files[0];
            alert("cambio il file");

            var index = cornerstoneFileImageLoader.addFile(file);

            // create an imageId for this image
            var imageId = "dicomfile://" + index;
            // load and display this image into the element
            var element = $('#dicomImage').get(0);
            cornerstone.loadImage(uriImageDesktop).then(function(image) {
                cornerstone.displayImage(element, image);
            });

        });

    });

</script>
</html>

使用此代码，我可以使用文件选择器显示单个HTML页面。有了这个组件，我可以导航到我的电脑，然后库加载Dicom图像。

现在，我想从URL传递Dicom图片的路径。

所以我正在尝试这样做

var uriImageDesktop = "C:\Users\michele\Desktop\deflate_tests\image";
            // load and display this image into the element
            var element = $('#dicomImage').get(0);
            cornerstone.loadImage(uriImageDesktop).then(function(image) {
                cornerstone.displayImage(element, image);
            });

此刻我需要静态dicom图像，但找不到。

问题是，如何从dicom文件中传递路径，然后显示它？

Answer 1

您在这里缺少图像加载器部分。基石要求图像加载器将您的链接转换为基石可读取的图像对象。如果您查看cornerstone's github repo，将会发现两个图像加载器。 WADO图像加载器可用于读取DICOM文件。尽管由于浏览器将无法访问服务器文件，但是您将必须构建一个后端来提供DICOM文件。如果您有一个uri来访问DICOM文件：

import * as cornerstone from "cornerstone-core"
import * as cornerstoneWADOImageLoader from "cornerstone-wado-image-loader"
cornerstoneWADOImageLoader.external.cornerstone = cornerstone

const uriServed = "http://xxx/deflate_tests/image"
const element = $('#dicomImage').get(0);
cornerstone.loadImage("wadouri:" + uriServed).then(image => {
  cornerstone.displayImage(element, image);
 });

NB ：如果您没有npm，只需将脚本链接到.js文件而不是导入（或者也可以在ES6 +中将其导入）

Answer 2

也许URI格式无效。该示例不包含方案。

file://c:/Users/user/Desktop/images/image.dcm

可能会更好。

如何在基石库中传递dicom文件的路径并显示它？
