Question

我正在尝试将dicom文件（dicomized pdf report file）发送到多个PACS系统。在某些情况下，我可以这样做，而在其他一些情况下，我的日志中没有任何错误地发送了dicom。

这是我的java代码：

public void sendDicomPdfToPacs(String dcmFilePath) throws Exception, IOException {

    Path tmpPdfDcm = Paths.get(dcmFilePath+".dcm");

    GlobalConfig cfg = new GlobalConfig();
    String localPacsAet = "";
    String localPacsIp="";
    int localPacsPort=0;
    localPacsAet = cfg.getLocalPacsAet1();
    localPacsPort = cfg.getLocalPacsPort1();
    localPacsIp = cfg.getLocalPacsIp();

    DcmEcho dcmEcho = new DcmEcho("device");
    dcmEcho.setRemoteHost(localPacsIp);
    dcmEcho.setRemotePort(localPacsPort);
    dcmEcho.setCalledAET(localPacsAet, true);
    dcmEcho.setCalling("DCMROUTER");

    Boolean dcmPacsStatus=false;

    try {
        dcmEcho.open();
        dcmPacsStatus=true;
        log.info("PACS is up and running");
        dcmEcho.close();
    } catch (IOException ex) {
        ...
    }


    if(dcmPacsStatus) {
        DcmSnd dcmsnd = new DcmSnd("device");

        //Set parameters AET
        dcmsnd.setCalledAET(localPacsAet);
        dcmsnd.setRemoteHost(localPacsIp);
        dcmsnd.setRemotePort(localPacsPort);
        dcmsnd.setCalling("DCMROUTER");

        //Set other default parameters
        dcmsnd.setOfferDefaultTransferSyntaxInSeparatePresentationContext(false);
        dcmsnd.setSendFileRef(false);
        dcmsnd.setStorageCommitment(false);
        dcmsnd.setPackPDV(true);
        dcmsnd.setTcpNoDelay(true);
        //Add DICOM file
        dcmsnd.addFile(tmpPdfDcm.toFile());
        // Configure transfer capability
        dcmsnd.configureTransferCapability();
        try {
            dcmsnd.start();
            log.info("Dicom Send initiated...");
        } catch (Exception e) {
            ...
        }

        try {
            long t1 = System.currentTimeMillis();
            dcmsnd.open();
            long t2 = System.currentTimeMillis();
            Logger.getLogger("Connected to " + localPacsAet + " in " + ((t2-t1)/1000F)+ "s");
            dcmsnd.send();
            dcmsnd.close();
            log.info("Released connection to " + localPacsAet);
        } catch (IOException e) {
           ...
        }  finally {
            dcmsnd.stop();

            /* delete dicom file! */
           ...

        }
    } else {
        log.info("Local PACS is down... Can not perform DICOM send request.");
    }
}

如果我尝试发送到Osirix PACS，那么dicom文件将成功发送...

如果我尝试发送到其他PACS系统（例如Agfa），那么我收到以下消息到我的日志：

所以我猜这个特殊的PACS因为以下原因而拒绝了我的发送请求：

A-ASSOCIATE-RJ[result=1, source=1, reason=2]: permanent application-context-name-not-supported

那是什么意思？我在这里缺少什么？

Answer 1

你是对的。 PACS可能不支持Encapsulated PDF SOP类。您可以通过将日志放在DEBUG上来获取更多信息 - 如果启用了DEBUG日志记录，您收到的A-ASSOCIATE-RJ消息将指示不支持哪种表示上下文（SOP类+传输语法）。

http://medical.nema.org/dicom/2013/output/chtml/part08/sect_9.3.html是标准中的相关部分。

简单地存储数据可能在Agfa PACS系统中可配置。与您建议的演示文稿上下文联系网站的PACS管理员，他们可以添加它。

Answer 2

服务器提供的关联拒绝原因是“不支持应用程序上下文名称”。这意味着SCU正在为SCP不支持的应用程序上下文名称提出UID。尝试使用DICOM 3.0的默认应用程序上下文名称UID - “1.2.840.10008.3.1.1.1”

Dcm4che无法将dicom文件发送到多个PACS - 永久性应用程序上下文名称不支持
