概述

LEADTOOLS存储服务管理器DICOM侦听服务通过一个或多个C-FIND Reponses来响应收到的C-FIND请求。 C-FIND Reponses包含请求中指定的DICOM属性。

要使用自定义数据库模式，必须定义配置文件，以便DICOM侦听服务使用适当的属性填充C-FIND Reponses，并使用数据库中的相应数据设置属性值。

LEAD Storage Server Manager附带的默认配置文件名为QueryIOD.xml。 默认配置定义为返回数据库的属性和属性序列。 对于教程数据库，我们不返回项目序列。

QueryIOD.xml的结构如下。 它由<patientLevel>，<studyLevel>，<seriesLevel>和<imageLevel>元素组成，每个元素都包含一个或多个<element>元素。

<query> 
<patientLevel> 
<element>...</element> 
<element>...</element> 
... 
</patientLevel> 

<studyLevel> 
<element>...</element> 
<element>...</element> 
... 
</ studyLevel > 

< seriesLevel > 
<element>...</element> 
<element>...</element> 
... 
</ seriesLevel > 

<imageLevel> 
<element>...</element> 
<element>...</element> 
... 
</ imageLevel > 
</query>

每个<element>元素对应于C-FIND请求中的属性，并提供数据库中相应值的映射。

以下是教程数据库的示例<element>。 它将DICOM元素PatientID（0010,0010）映射到相应的表名（MyPatientTable）和列（PatientName）。

<element tag="(0010,0010)" 
     tagName="PatientName" 
    vr="PN" 
    minVM="1" 
    maxVM="1" 
    vmDivider="1" 
    keyType="Required" 
    matchingType="WildCard" 
    tableName="MyPatientTable"  
    matchingEntity="My.Medical.Storage.DataAccessLayer.Entities.MyPatient,My.Medical.Storage.DataAccessLayer" 
    columnsName="PatientName" />

MyQueryIOD.xml的全部内容如下：

<?xml version="1.0" encoding="utf-8" ?> 
<query> 
   <patientLevel> 
      <element tag="(0010,0010)"
