leadtools提供了封装后的dicom插件，可以非常方便的开发出dicom 通讯部分的组件，本篇博客讲解如何使用相关的接口进行代码编写，实现Dicom协议中的查询操作。
1.用vs2015创建一个winform项目，引用下面的dll，并在代码里引用
using Leadtools; using Leadtools.Dicom; using Leadtools.Dicom.Scu.Common; using Leadtools.Dicom.Scu; using Leadtools.MedicalViewer; using System.Net; using System.IO;
2.创建下面的对象
// CFind highlevel 对象 private QueryRetrieveScu _cfind; private DicomScp _server = new DicomScp(); private TreeNode _currentnode; private MedicalViewer _viewer;
3.初始化服务器和客户端参数，
本次用的服务器即是开发包中运行pacs服务器设置程序后，创建的L19_PACS_SCP64
在查询过程中主要是使用MatchStudy和MatchSeries事件来获取相应的结果，使用Moved事件来接收传输过来的图片
private void initServer() { _server = new DicomScp(); _server.AETitle = "L19_PACS_SCP64"; _server.PeerAddress = IPAddress.Parse("10.32.1.75"); _server.Port = 534; _server.Timeout = 30; }
private void initCfind() { _cfind = new QueryRetrieveScu(); _cfind.AETitle = "L19_CLIENT64"; _cfind.HostPort = 1030; //查询Study _cfind.MatchStudy += _cfind_MatchStudy; //查询Series _cfind.MatchSeries += _cfind_MatchSeries; //MOVE _cfind.Moved += _cfind_Moved; }
private void _cfind_MatchSeries(object sender, MatchEventArgs<Series> e) { TreeNode seriesnode = new TreeNode(e.Info.Date != null ? e.Info.Date.Value.ToShortDateString() : "未知"); seriesnode.Tag = e.Info; _currentnode.Nodes.Add(seriesnode); } private void _cfind_MatchStudy(object sender, MatchEventArgs<Study> e) { TreeNode studynode = new TreeNode(e.Info.Patient.Name.Full); studynode.Tag = e.Info; querytree.Nodes.Add(studynode); }
public delegate void ReceiveFindMovedDelegate(Leadtools.Dicom.Scu.Common.MovedEventArgs e); private void _cfind_Moved(object sender, MovedEventArgs e) { ReceiveFindMoved(e); } //加载图片 void ReceiveFindMoved(MovedEventArgs e) { if (InvokeRequired) { Invoke(new ReceiveFindMovedDelegate(ReceiveFindMoved), e); } else { ImageInstance instance = e.Instance as ImageInstance; int cols = 1; int rows = 1; RasterImage ri = instance.Images; if (instance != null && instance.Images != null) { int pageCount = instance.Images.PageCount; if (pageCount > 1) { // Display at most 6 x 6 (36) frames if (pageCount >= 36) { cols = 6; rows = 6; } else { cols = (int)Math.Floor(Math.Sqrt(pageCount)); rows = (int)Math.Ceiling((double)pageCount / cols); } } MedicalViewerMultiCell m = GetCell(); m.Rows = rows; m.Columns = cols; if (m.Image != null) { for (int pageIndex = 0; pageIndex < instance.Images.PageCount; pageIndex++) { instance.Images.Page = pageIndex + 1; try { m.Image.AddPage(instance.Images); } catch (Exception ex) { Console.WriteLine(ex.Message); } } } else { m.Image = instance.Images; } if (pageCount > 1) { m.SetTag(0, MedicalViewerTagAlignment.TopLeft, MedicalViewerTagType.Frame); m.ShowTags = true; } m.SetTag(1, MedicalViewerTagAlignment.BottomLeft, MedicalViewerTagType.WindowLevelData); // Give the medical viewer cell the focus if (_viewer.Cells.Count > 0 && _viewer.Cells[0] is MedicalViewerBaseCell) { (_viewer.Cells[0] as MedicalViewerBaseCell).Selected = true; } m.SetScaleMode(MedicalViewerScaleMode.Fit); } } }
初始化完成后即可使用下面的命令来查询
查询study
_cfind.Find(_server, new FindQuery());
查询特定study的series
FindQuery query = new FindQuery(); Study study = td.Tag as Study; query.QueryLevel = QueryLevel.Series; query.PatientId = study.Patient.Id; query.StudyInstanceUID = study.InstanceUID; _cfind.Find(_server, query);
用Move方法检索图片，参数依次为服务器对象，客户端aetitle，Study InstanceUID，Series InstanceUID
_cfind.Move(_server, _cfind.AETitle, (e.Node.Parent.Tag as Study).InstanceUID, (e.Node.Tag as Series).InstanceUID);
下面是对应的项目代码，Store和Find功能都包含在里面
