Question

特定PACS的

C查找（请求工作清单）返回“不支持可选密钥” ，并且不返回任何数据。我还尝试使用空字符串“”代替null作为患者ID，现有患者ID等，因此结果相同。该请求适用于其他PACS。

这是怎么回事，如何解决？

请求代码（使用Fellow Oak DICOM fo-dicom）：

var cfind = DicomCFindRequest.CreateWorklistQuery();

List<Dicom.DicomDataset> dslist = new List<Dicom.DicomDataset>();

cfind.OnResponseReceived = (DicomCFindRequest rq, DicomCFindResponse rp) =>
{

    if (rp.Status != DicomStatus.Pending)
    {                 
        return;
    }           

    dslist.Add(rp.Dataset);
};

var client = new DicomClient();
client.AddRequest(cfind);

try
{                
    await client.SendAsync(destip, port, useTLS, callingAE, calledAE);
}
catch (Exception e)
{
    logger.Error(e);                
}

这是日志。

所以我解决了这个问题，“不支持可选键”是一条信息消息，实际上已接收到数据。

        request.OnResponseReceived += (req, rp) =>
        {
            if (rp.HasDataset)
            {
                dslist.Add(rp.Dataset);
            }

            if (rp.Status != DicomStatus.Pending && rp.Status != DicomStatus.QueryRetrieveOptionalKeysNotSupported)
            {                    
                return;
            }              
        };

只需添加状态的含义：它告诉您您的请求指定了Worklist-SCP不支持的匹配密钥。这意味着您可能会在响应中收到与查询条件不匹配且应由SCP过滤掉的工作清单记录。

WorklistQuery（C-FIND）返回C查找响应[2]：不支持可选键
