我是使用dcm4che2库编程的新手,我正在编写一个简单的程序来查询PACS服务器,方法是将查询/检索级别设置为患者/系列/图像。
代码非常简单,在某些情况下,它工作正常:
dcmqr.setCalledAET("AET_REMOTE", true);
dcmqr.setRemoteHost("aa.bb.cc.dd");
dcmqr.setRemotePort(xxxx);
dcmqr.getKeys();
dcmqr.setDateTimeMatching(true);
dcmqr.setCFind(true);
dcmqr.setCGet(false);
dcmqr.configureTransferCapability(true);
dcmqr.setQueryLevel(DcmQR.QueryRetrieveLevel.IMAGE);
dcmqr.addMatchingKey(new int[]{Tag.PatientName},sPatientName);
dcmqr.addMatchingKey(new int[]{Tag.Modality},sModality);
dcmqr.addMatchingKey(new int[]{Tag.AccessionNumber},sAccession);
dcmqr.addMatchingKey(new int[]{Tag.SeriesNumber},sSeriesNumber);
dcmqr.addReturnKey(new int[]{Tag.SeriesDescription});
dcmqr.addReturnKey(new int[]{Tag.StudyDescription});
dcmqr.addReturnKey(new int[]{Tag.PatientBirthDate});
dcmqr.addReturnKey(new int[]{Tag.PatientSex});
List<DicomObject> result = null;
try{
dcmqr.start();
dcmqr.open();
result = dcmqr.query();
dcmqr.stop();
dcmqr.close();
}
catch(Exception e){
...
}
但是在某些情况下(每当我将查询/检索级别设置为&#34; Image&#34;)时,query()方法失败(&#34; DIMSE RSP中的意外消息ID&#34;)和抛出A-Abort命令,如下所示:
...

实际上,我无法理解这个错误意味着什么,并找出解决方案。 我想这是一个沟通问题.. 有人可以帮助我吗?
感谢。

您的日志记录表明您已发出查询请求#3,然后收到查询请求#2的响应。如果监听器现在期望3的响应,那么它将抛出异常,因为它已收到消息2的消息ID。
如果要循环查询调用以执行此操作,则可以尝试将实例指定为列表:
addMatchingKey( new int[] { Tag.SeriesInstanceUID }, "uid1\\uid2\\uid3" );
