In this tutorial, you will learn how to display a reference line in the Medical Viewer Cells.
- Open Visual Studio 2005 or later.
- From File menu > choose Project.
- The new project dialog appears.
- From project types, expand the Other languages node, and click on the Visual C# node.
- From the template list on the left side of the dialog, choose Windows Forms Application.
- Type the project name as "Working With Reference Lines" in the Project Name field, and then choose OK.
- Select OK to create the project.
- From View menu > choose Solution explorer.
- On the Solution explorer tree, right click on the References node and select Add Reference.
- On the Add Reference dialog, select the Browse tab, and add the following dll's:
- Leadtools.dll
- Leadtools.Codecs.dll
- Leadtools.MedicalViewer.dll
- Leadtools.Medical3D.dll
- Leadtools.Dicom.dll
- Leadtools.Codecs.Cmp.dll
- Switch to Form1 code view (right-click Form1 in the solution explorer then select View Code ) and add the following lines at the beginning of the file:
[Visual Basic]Imports Leadtools Imports Leadtools.Codecs Imports Leadtools.MedicalViewer Imports Leadtools.Medical3D Imports Leadtools.Dicom[C#]using Leadtools; using Leadtools.Codecs; using Leadtools.MedicalViewer; using Leadtools.Medical3D; using Leadtools.Dicom; - In Form1, create a new method InitClass(). Add the following code in the InitClass() method:
[Visual Basic]Private Sub InitClass() RasterSupport.Unlock(RasterSupportType.Dicom, " Your Dicom Key") RasterSupport.Unlock(RasterSupportType.Medical, "Your Medical Key") RasterSupport.Unlock(RasterSupportType.Medical3d, "Your Medical 3D Key") ' Create a new instance of the Codecs class, which will be used to load the images. Dim _codecs As RasterCodecs = New RasterCodecs() ' Create a new instance of the Medical Viewer. The layout will be divided to 2X2. Dim viewer As MedicalViewer = New MedicalViewer(2, 2) ' Fit the view to the whole form viewer.Dock = DockStyle.Fill ' Add the viewer to the form Controls.Add(viewer) End Sub[C#]void InitClass() { RasterSupport.Unlock(RasterSupportType.Dicom, " Your Dicom Key"); RasterSupport.Unlock(RasterSupportType.Medical, "Your Medical Key"); RasterSupport.Unlock(RasterSupportType.Medical3d, "Your Medical 3D Key"); // Create a new instance of the Codecs class, which will be used to load the images. RasterCodecs _codecs = new RasterCodecs(); // Create a new instance of the Medical Viewer. The layout will be divided to 2X2. MedicalViewer viewer = new MedicalViewer(2, 2); // Fit the view to the whole form viewer.Dock = DockStyle.Fill; // Add the viewer to the form Controls.Add(viewer); }Note: For more information on how to acquire the above unlock keys, please contact LEAD Technologies support.
- Call the InitClass method from inside the Form1 constructor and place the call after InitializeComponent();
- Run the program and you will see a 2x2 layout.
-
Note: For the next step, you will need to have a DICOMDIR file. We provide DICOMDIR sample files which can be downloaded from here. For more information on building 3D objects from a DICOMDIR, please see Loading a DICOMDIR To Create a 3D Object.
Note: If you encounter an "Invalid File Format" or "Feature Not Supported" exception, please refer to the topic Invalid File Format/Feature Not Supported.
Download the sample DICOMDIR and uncompress the contents to the folder: C:\Leadtools_DICOMDIR.
- Add the following code to the Form1 class. This code is for loading the images from the DICOMDIR, sorting them and extracting all the useful information:
