如何在遠程dicom服務器中推送壓縮的CT文件？

Question

我使用DcmSnd工具將壓縮的CT文件推送到遠程Dicom服務器中，問題是在使用DcmQr從同一服務器檢索未壓縮的文件時，我獲得了所有文件，但以圖像形式出現，它為我提供了所有文件的失敗狀態。

class:  1.2.840.10008.5.1.4.1.2.2.1/Study Root Query/Retrieve Information Model - FIND
status: ff01

然后，它開始對所有文件進行解壓縮

我用於將文件推送到遠程dicom Server的DcmSnd工具是否適合壓縮文件？

Answer 1

我不知道DcmSnd，但是您可以嘗試Orthanc ，它支持通過DICOM協議發送壓縮文件（即，它支持C-Store SCU的JPEG / JPEG2k傳輸語法）。

Answer 2

根據以上日志，您的關聯請求的呈現上下文“ 5”和“ 11”僅包含CT圖像存儲的未壓縮傳輸語法。 Sever接受您的建議，並使用表示上下文“ 11”（即Explicite VR Little Endian）以約定的傳輸語法發送數據。 嘗試將帶有壓縮傳輸語法的CT圖像存儲抽象語法的附加表示上下文添加到關聯請求命令中。
