DICOM: Annotate DICOM images in WinForms

In This Topic

The annotations may be displayed over the DICOM image in WinForms image viewer.

For each annotation is implemented a class, which defines the way the annotation appearance is displayed and how the user can interact with the annotation:

Rectangle annotation - appearance and interaction with annotation is defined using DicomRectangleAnnotationView class
Ellipse annotation - appearance and interaction with annotation is defined using DicomEllipseAnnotationView class
Point annotation - appearance and interaction with annotation is defined using DicomPointAnnotationView class
Polyline annotation - appearance and interaction with annotation is defined using DicomPolylineAnnotationView class
Multiline annotation - appearance and interaction with annotation is defined using DicomMultilineAnnotationView class
Range line annotation - appearance and interaction with annotation is defined using DicomRangeLineAnnotationView class
Arrow annotation - appearance and interaction with annotation is defined using DicomArrowAnnotationView class
Text annotation - appearance and interaction with annotation is defined using DicomTextAnnotationView class

The DicomAnnotationTool class allows to display and edit the annotations of DICOM image in WinForms image viewer.

Here is C#/VB.NET code that demonstrates how to display annotations of DICOM file in WinForms image viewer:

// create a DICOM visual tool
Vintasoft.Imaging.Annotation.Dicom.UI.VisualTools.DicomAnnotationTool annotationTool = 
    new Vintasoft.Imaging.Annotation.Dicom.UI.VisualTools.DicomAnnotationTool();
// set the DICOM visual tool as active visual tool in image viewer
viewer.VisualTool = annotationTool;

// load a presentation state file
Vintasoft.Imaging.Codecs.ImageFiles.Dicom.DicomFile presentationStateFile = 
    new Vintasoft.Imaging.Codecs.ImageFiles.Dicom.DicomFile(presentationStateFilePath);
// add DICOM annotations from the presentation state file to the DICOM visual tool
annotationTool.AnnotationDataController.AddAnnotationDataSet(presentationStateFile.Annotations);

// load a DICOM file in the image viewer
viewer.Images.Add(dicomFilePath);

VB.NET

' create a DICOM visual tool
Dim annotationTool As New Vintasoft.Imaging.Annotation.Dicom.UI.VisualTools.DicomAnnotationTool()
' set the DICOM visual tool as active visual tool in image viewer
viewer.VisualTool = annotationTool

' load a presentation state file
Dim presentationStateFile As New Vintasoft.Imaging.Codecs.ImageFiles.Dicom.DicomFile(presentationStateFilePath)
' add DICOM annotations from the presentation state file to the DICOM visual tool
annotationTool.AnnotationDataController.AddAnnotationDataSet(presentationStateFile.Annotations)

' load a DICOM file in the image viewer
viewer.Images.Add(dicomFilePath)
