CFind在研究级别上失败-不支持SOP类或找不到抽象语法的可接受的表示上下文

Han*_*ans 7 c# dicom fo-dicom

该应用程序尝试在患者级别进行CFind，获取研究，进行研究，获取系列，最后得到图像。

该代码在查询两个不同的PACS实现时有效，但在研究级别的第三个失败。

发出患者请求的代码部分

var request = DicomCFindRequest.CreatePatientQuery(patientId: _patientid, patientName: _patientname);

var client = new DicomClient();
client.AddRequest(request);
await client.SendAsync(destip, port, useTLS, callingAE, calledAE);

对于学习水平

request = DicomCFindRequest.CreateStudyQuery(patientId: _patientid);

通过检查日志并比较工具中的日志，似乎应该有一个抽象语法列表，而不仅仅是一个？还是什么问题？

var request = DicomCFindRequest.CreatePatientQuery(patientId: _patientid, patientName: _patientname);

var client = new DicomClient();
client.AddRequest(request);
await client.SendAsync(destip, port, useTLS, callingAE, calledAE);

来自jdicom的日志，该日志可以在学习级别执行cfind请求

request = DicomCFindRequest.CreateStudyQuery(patientId: _patientid);

编辑，
这是一致性声明。 https://sectramedical.blob.core.windows.net/uploads/2018/04/pacs-dicom-conformance-statement-20.1.pdf

但是，如果不支持CFind，将使用哪种方法检索研究和序列？我在这里迷路了，但我非常感谢您抽出宝贵的时间来提示。

这是其他工具的日志（由于帖子的最大长度而被截断了），该工具设法列出了患者和研究内容，并且一些屏幕截图显示了可能的结果。Radiant还提供了一个屏幕截图，该屏幕截图也可以连接，显示患者并显示图像。

从您对问题的出色描述来看，对我来说似乎很明显，您正在测试的第三个PACS显然不支持“研究根查询”。

您的关联请求是正确构成的，除了每个Presentation Context只能提出一个抽象语法外，不可能提出其他建议。但是，PACS随后会回答：

Presentation Contexts:  1
  Presentation Context:  1 [RejectAbstractSyntaxNotSupported]
       Abstract Syntax:  Study Root Query/Retrieve Information Model - FIND
       Transfer Syntax:  Implicit VR Little Endian: Default Transfer Syntax for DICOM
Run Code Online (Sandbox Code Playgroud)

告诉您根本不支持此服务。

通信失败的日志似乎已缩短。从dcm4chee日志中，您可以得出还提出了另一个Q / R信息模型。这是患者根模型：

1    1.2.840.10008.5.1.4.1.2.1.1     3     Patient Root Query/Retrieve Information Model - FIND SOP Cl...
  ts-0     1.2.840.10008.1.2               Implicit VR Little Endian Transfer Syntax
Run Code Online (Sandbox Code Playgroud)

知道是否支持此功能将很有趣。因为如果没有，您正在与之交谈的系统几乎不能称为“ PACS”。我建议看一下有关系统的DICOM符合性声明。它应该传达您是否在与正确的应用程序实体（标题）对话，以及是否支持Query / Retrieve服务类的特定信息模型。

如果您发布了完整的日志文件，则表示上下文可能取决于您放置查询的方式：

var request = DicomCFindRequest.CreatePatientQuery(patientId: _patientid, patientName: _patientname);
Run Code Online (Sandbox Code Playgroud)

在这种情况下，您可能需要尝试CreateStudyQuery（），该方法还可以指定患者参数。

简而言之，DICOM信息模型：

  • 患者根：患者ID唯一标识患者。
  • 研究根：患者信息被视为研究级别的辅助信息

[编辑] 查看Sectra PACS的DICOM符合性声明后：也许您连接到错误的应用程序实体。Sectra PACS似乎具有不同的应用程序实体（即相同的IP，可能是相同/不同的端口，但具有不同的AET）来处理存储和查询/检索服务。您要处理的AET看起来可疑：

Calling AE Title:       TEST_01
Called AE Title:        DICOM_STORAGE
Remote host:            xxx.29.51.150
Remote port:            7817
Implementation Class:   Unknown [1.2.752.24.3.3.25.7]
Implementation Version: WISSTOSCP_20_1
Run Code Online (Sandbox Code Playgroud)

请注意被称为AE标题和实现版本。两者似乎都属于存储SCP，根据DCS的说法，它根本不支持任何查询/检索服务。

因此，我认为您需要更改要查询的AE的配置。

  • DCS很有帮助。请看我的编辑。 (2认同)
  • 这听起来不只是希望，而且我很确定它会起作用 (2认同)
  • @Hans RetrieveAETitle指定您应将后续“检索”（即C-GET或C-MOVE）定向到的SCP的应用程序实体标题（AET）。对于所有Q / R级别，应由同一AET处理“查询”（C-FIND）。 (2认同)
  • 正确，但在DCS中，只有一个应用程序实体用于查询和检索。因此，AET DICOM_QR_SCP也很可能也适合解决查询问题。 (2认同)
