PixelToWorld Method (DicomImage3D)

In This Topic

Calculate the real world location of a point displayed on a 3D image

Syntax

Visual Basic
C#

'Declaration
 
Public Function PixelToWorld( _
   ByVal Point As System.Drawing.PointF, _
   ByVal DisplaySize As System.Drawing.Size _
) As System.Windows.Media.Media3D.Point3D

public System.Windows.Media.Media3D.Point3D PixelToWorld( 
   System.Drawing.PointF Point,
   System.Drawing.Size DisplaySize
)

Parameters

Point
DisplaySize

Remarks

This method is suitable for MPR and Slab images, and whilst it will provide a value for "projectional" MIP and VR images the point will be on the "central plane" of that view, and is not really localised to a single point in space.

Example

DicomImage image = new DicomImage("your_3D_dicom_image.dcm");
DicomVolume volume = new DicomVolume(image);
                     
RenderMode3D renderMode = RenderMode3D.VR;
DicomImage3D image3D = new DicomImage3D(volume, renderMode);   
            
Size displaySize = new Size(image3D.Size.Width, image3D.Size.Height);
PointF pixelLocation = new PointF(displaySize.Width / 2, displaySize.Height / 2);
Point3D worldPoint = image3D.PixelToWorld(pixelLocation, displaySize);        
             
Viewer.Images.Add(image3D);

Requirements

Target Platforms: .NET CLR 4.8 or higher
