Dicom C-move 請求QR服務

個人理解 Dicom C-get 就是在沒有設置任何驗證情況下請求QR服務，而C-move是有驗證的情況下請求QR服務。一般都是C-move，因為機器都需要驗證。

Dicom C-move 原理：自己寫一個SCU程序，通過scu發送請求給QR服務，再用自己的SCP來接收QR的C-Store回傳的影像。

需要引用Dicom.Core 4.0.8.0或以下

 

  /// <summary>
        /// C-Store SCP AE Title：影像歸檔目的地的 AE Title，之所以這樣寫，是因為 C-Move 既可以是兩方通信，也可以是三方通信，如果是兩方通信，那么 C-Move SCU 同時需要提供 C-Store SCP 的功
        /// 能，這里就可以寫 C-Move SCU 的 AE Title；如果是三方通信，那么這個影像歸檔的目的地之需要提供 C-Store SCP 的功能，所以這里的參數就要寫C-Store SCP 的 AE Title；
        /// StudyInstanceUID：檢查唯一標識；
        /// C-Move SCP IP：C-Move 服務端的 IP 地址或機器名；
        /// C-Move SCP Port：C-Move 服務端的端口；
        /// C-Move SCU AE Title：C-Move 客戶端應用實體的名稱；
        /// C-Move SCP AE Title：C-Move 服務端應用實體的名稱；
