我正在尝试将 dicom 文件（dicomized pdf 报告文件）发送到多个 PACS 系统。在某些情况下，我可以做到这一点，而在其他一些情况下，没有在我的日志中没有任何错误的情况下发送 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，则 dicom 文件正在成功发送...

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

所以我猜这个特定的 PACS 拒绝了我的发送请求，因为：

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

那么这是什么意思呢？我在这里想念什么？

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些表示上下文（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。

在 Agfa PACS 系统中简单地存储数据可能是可配置的。联系站点的 PACS 管理员并提供您建议的演示上下文，他们可能会添加它。

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议一个 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”
