leadtools爲web端提供了wcf接口來供用戶能夠登陸pacs系統，檢索，查看以及上傳影像。本篇博客講解如何建立一個網頁來實現上傳功能，經過WCF進行dicom文件的上傳時，是將dicom文件轉換爲base64數據流，分段進行傳輸。html

本篇博客運行的前提是已經部署完成Leadtools HTML5 Web Viewer，能夠正常瀏覽。參考https://www.evget.com/article/2018/2/6/27757.htmljquery

在部署完成後，將下面的代碼複製到一個HTML文件中，便可運行進行測試。另外須要添加html文件所需的jquery.min.js到同文件夾路徑下。web
