如何在远程dicom服务器上推送压缩的CT文件？

Question

我使用DcmSnd工具推送压缩的CT文件在远程Dicom server.The的问题是，当检索未压缩的文件从同一服务器使用DcmQr我得到所有的文件，但以图像的形式，它给我失败的状态为所有文件。

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

然后它开始解压所有的文件

我用来将文件推送到远程dicom服务器的DcmSnd工具是否适用于压缩文件？

Answer 1

我不知道DcmSnd，但是你可以试试Orthanc，它支持通过DICOM协议发送压缩文件(即它支持C-Store SCU的JPEG/JPEG2k传输语法)。

Answer 2

根据上面的日志，您的助理请求的演示上下文“5”和“11”仅包含用于CT图像存储的未压缩传输语法。服务器接受您的建议，并使用演示上下文“11”以约定的传输语法发送数据(这是显式VR Little Endian)。尝试使用压缩传输语法将CT Image Storage抽象语法的其他演示文稿上下文添加到您的关联请求命令。
