Java 从dcm4che2迁移到dcm4che3

我在java项目中使用了下面提到的来自该存储库的dcm4che2 API

dcm4che-core-2.0.29.jar

org.dcm4che2.data.DicomObject  
org.dcm4che2.io.StopTagInputHandler  
org.dcm4che2.data.BasicDicomObject  
org.dcm4che2.data.UIDDictionary  
org.dcm4che2.data.DicomElement  
org.dcm4che2.data.SimpleDcmElement  
org.dcm4che2.net.service.StorageCommitmentService  
org.dcm4che2.util.CloseUtils  

dcm4che-net-2.0.29.jar

org.dcm4che2.net.CommandUtils  
org.dcm4che2.net.ConfigurationException  
org.dcm4che2.net.NetworkApplicationEntity  
org.dcm4che2.net.NetworkConnection  
org.dcm4che2.net.NewThreadExecutor  
org.dcm4che3.net.service.StorageService  
org.dcm4che3.net.service.VerificationService  

目前我想迁移到dcm4che3，但在我从该存储库下载的dcm4che3中找不到上面列出的API

您能为我提供另一种方法吗？

正如您已经观察到的，基本的IComboject已经成为历史——与其他许多项目一样

新的“Dicom对象”是属性——对象是属性的集合

因此，您创建属性，用RQ行为（C-FIND等）所需的标记填充它们，而您得到的回报是另一个Attributes对象，您可以从中提取所需的标记

在我看来，dcm4che 2.x在处理个人价值表示的问题上是模糊的。dcm4che 3.x更加清晰

迁移需要重写有关如何查询以及如何处理单个标记的代码。另一方面，dcm4che 3.x使新代码不那么复杂

一个相当完整的例子，从PACS中检索给定登录号的研究；设置查询并处理结果：

    String modality = null;
    String accessionNumber = "1234567890";

    //--------------------------------------------------------
    // HERE follows setup of a query, using an Attributes object
    //--------------------------------------------------------
    Attributes query = new Attributes();

    // Indicate character set
    {
        int tag = Tag.SpecificCharacterSet;
        VR vr = ElementDictionary.vrOf(tag, query.getPrivateCreator(tag));
        query.setString(tag, vr, "ISO_IR 100");
    }

    // Study level query
    {
        int tag = Tag.QueryRetrieveLevel;
        VR vr = ElementDictionary.vrOf(tag, query.getPrivateCreator(tag));
        query.setString(tag, vr, "STUDY");
    }

    // Accession number
    {
        int tag = Tag.AccessionNumber;
        VR vr = ElementDictionary.vrOf(tag, query.getPrivateCreator(tag));
        query.setString(tag, vr, accessionNumber);
    }

    // Optionally filter on modality in study if 'modality' is provided,
    // otherwise retrieve modality
    {
        int tag = Tag.ModalitiesInStudy; 
        VR vr = ElementDictionary.vrOf(tag, query.getPrivateCreator(tag));
        if (null != modality && modality.length() > 0) {
            query.setString(tag, vr, modality);
         } else {
            query.setNull(tag, vr);
         }
    }

    // We are interested in study instance UID
    {
        int tag = Tag.StudyInstanceUID;
        VR vr = ElementDictionary.vrOf(tag, query.getPrivateCreator(tag));
        query.setNull(tag, vr);
    }

    // Do the actual query, needing an AppliationEntity (ae), 
    // a local (local) and remote (remote) Connection, and 
    // an AAssociateRQ (rq) set up earlier.

    // 1) Open a connection to the SCP
    Association as = ae.connect(local, remote, rq);

    // 2) Query
    int priority = 0x0002; // low for the sake of demo :)
    as.cfind(UID.StudyRootQueryRetrieveInformationModelFIND, query, null,
             new DimseRSPHandler(as.nextMessageID()) {

        @Override
        public void onDimseRSP(Association assoc, Attributes cmd,
                               Attributes response) {

            super.onDimseRSP(assoc, cmd, response);

            int status = cmd.getInt(Tag.Status, -1);
            if (Status.isPending(status)) {
                //--------------------------------------------------------
                // HERE follows handling of the response, which
                // is just another Attributes object
                //--------------------------------------------------------
                String studyInstanceUID = response.getString(Tag.StudyInstanceUID);
                // etc...
            }
        }
    });

    // 3) Close the connection to the SCP
    if (as != null && as.isReadyForDataTransfer()) {
        as.waitForOutstandingRSP();
        as.release();
        as = null;
    }

有没有更合适的方法来处理响应，而不是执行

@Override public void onDimseRSP（…

）？有一个版本的

cfind（）

返回一个

DimseRSP

对象，而不是

void

，但我无法使它工作，因为它似乎是异步的，我不知道如何让程序在检查返回的内容之前等待响应。我找到了解决方案。这是方法：

DimseRSP rsp=assoc.cfind（…）；assoc.waitforoutstandingsp（）；while（rsp.next（））{Attributes data=rsp.getDataset（）；//然后处理数据…}
