GetNewViewPerspective(DicomDataSet,RasterViewPerspective,OrientationConfiguration) Method

Summary

Gets a new RasterViewPerspective that results from applying an OrientationConfiguration to a given RasterViewPerspective.

Syntax

C++/CLI

public static RasterViewPerspective GetNewViewPerspective( 
   this DicomDataSet ds, 
   RasterViewPerspective currentViewPerspective, 
   OrientationConfiguration orientation 
)

[ExtensionAttribute()] 
public: 
static RasterViewPerspective GetNewViewPerspective(  
   DicomDataSet^ ds, 
   RasterViewPerspective currentViewPerspective, 
   OrientationConfiguration^ orientation 
)

Parameters

ds
The DicomDataSet that contains the image orientation vectors

currentViewPerspective
The input RasterViewPerspective to which the PlaneOrientation will be applied.

orientation
An OrientationConfiguration that will be applied to the current view perspective.

Remarks

This overload gets the image orientation vectors from the ds.

The input view perspective is defined by two values: the original RasterViewPerspective, and a row and column orientation vector (which are read from the ds by searching for the DicomElement that has a tag of ImageOrientationPatient which contains the orientation vectors.). This method returns the new RasterViewPerspective that results from applying an OrientationConfiguration to the input view perspective. Note that the orientation contains three lists of conditions (one for each 3D axis) that can be applied to the image contained in the ds if the condition is met.

Example

This example does the following:

Loads a DICOM dataset that contains orientation vectors that orient it as a coronal slice
Creates an OrientationConfiguration that contains a coronal PlaneOrientation that corresponds to a horizontal flip
Applies the above to a view perspective, and returns the resulting view perspective
