c – 使用gdcm的“CompositeNetworkFunctions”进行DICOM C_MOVE

2023年10月11日 203次阅读

我试图使用gdcm的
CompositeNetworkFunctions从服务器获取DICOMS.

我的测试服务器使用“Orthanc”设置.

当我运行Move请求时,我得到：

terminate called after throwing an instance of 'gdcm::Exception'

what()：/ home / mameame / Build / GDCM / Source / Source / Common / gdcmException.h：74()：

当我发现Exception时,我发现它是一个“未处理的异常”,没有更多的信息.因此,我没有捕获它,而是使用gdb运行程序.这是我得到的：

这是我的代码：

mQuery.InitializeDataSet( mQueryLevel );
setSearchParameter( gdcm::Tag( 0x20, 0x000d ), studyUID.toStdString() );    // Study UID
setSearchParameter( gdcm::Tag( 0x20, 0x000e ), seriesUID.toStdString() );   // Series UID

std::cout << "New Move Query: " << mQuery.ValidateQuery(true) << std::endl;


mQuery.WriteQuery("MoveQuery.dcm");


bool res = gdcm::CompositeNetworkFunctions::CMove(
                "localhost", 4242,
                &mQuery,
                11110,
                "IMHOTEP",
                NULL,
                "/home/myname/TestPatient" );

mQueryLevel是gdcm :: eSeries

有趣的是,使用书面查询文件“MoveQuery.dcm”,我可以使用movescu下载文件：

movescu -v -p -aet IMHOTEP -od /home/myname/TestPatient/ --port 11110 localhost 4242 MoveQuery.dcm

我试过了：

> AET和CALL的不同值
>相对和绝对路径
>不同的端口(虽然不应该这样 – 毕竟我的movecu呼叫使用相同的端口！)
> mQuery目前的类型为gdcm :: MovePatientRootQuery,但我尝试过MoveStudyRootQuery,FindPatientRootQuery,FindStudyRootQuery
>在堆栈跟踪之后深入了解GDCM代码 – 但我不了解发生了什么
>也将“PatientID”的值添加到查询中,或仅提供“SeriesUID”(相同的结果)

在PatientID中也添加了查询,这里是MoveQuery.dcm的内容：

$dcmdump MoveQuery.dcm

最佳答案 C-GET服务在DICOM标准中没有退役. C-GET使用相同的连接从SCP检索图像,但C-MOVE使用并行连接,服务器将其角色切换到SCU(客户端),并尝试连接以移动目标AE(目标服务器).在这种情况下,您需要在您身边有一个DICOM监听器(SCP)来处理传入连接.

我想你是说Calling AE Title(C-Move服务请求者)是“IMHOTEP”,你应该有一个DICOM监听器监听端口“11110”.您正在请求远程AE“ORTHANC”(称为AE)将系列移动到C-Move Destination AE(这应该是您的“IMHOTEP”的DICOM侦听器(SCP)).
