Syntax

Methods

CalcualteIntersectionLocalizer(FrameGeometry, FrameGeometry, out Point2, out Point2)

This method calculates the localizer line of the sourceFrame that can be drawn on the destinationFrame. You should call the method CanDrawLocalizer prior to check if localizer calculation is valid on the two frames.

This method returns the line of common pixels where the two images intersect. If the two images intersect, then it returns

true

and the out parameters are filled with values. Otherwise the method returns

false

Declaration

public static bool CalcualteIntersectionLocalizer(FrameGeometry sourceFrame, FrameGeometry destinationFrame, out Point2 startPoint, out Point2 endPoint)

Parameters

Type	Name	Description
FrameGeometry	sourceFrame	The geometry of the frame, that is viewed by the user
FrameGeometry	destinationFrame	The geometry of the scout frame, where the localizer line should be drawn on
Point2	startPoint	If the frames intersect, then this contains the start point of the localizer line in terms of pixels on destinationFrame
Point2	endPoint	If the frames intersect, then this contains the end point of the localizer lin in terms of pixels on destinationFrame

Returns

Type	Description
Boolean

CalcualteProjectionLocalizer(DicomDataset, DicomDataset, out List<Point2>)

This method calculates the localizer rectangle of the sourceFrame that can be drawn on the destinationFrame. You should call the method CanDrawLocalizer prior to check if localizer calculation is valid on the two frames. This method will return the 4 points of a rectangle, although most image sets are orthogonal, resulting in the rectangle being presented as a straight line on the scout image. Since the source image is projected on the destination image there might me a result even if the two images do not intersect

Declaration

public static void CalcualteProjectionLocalizer(DicomDataset sourceFrame, DicomDataset destinationFrame, out List<Point2> localizerPoints)

Parameters

Type	Name	Description
DicomDataset	sourceFrame	The dataset of the frame, that is viewed by the user
DicomDataset	destinationFrame	The dataset of the scout frame, where the localizer line should be drawn on
List<Point2>	localizerPoints	This contains the points of the localizer rectangle in terms of pixels on destinationFrame

CanDrawLocalizer(FrameGeometry, FrameGeometry)

This method performes some checks, if it is valid or allowed that the location of the sourceFrame is drawn on the destinationFrame. This check should be called at least once before the more computation intensive method CalcualteLocalizer is called.

Declaration

public static bool CanDrawLocalizer(FrameGeometry sourceFrame, FrameGeometry destinationFrame)

Parameters

Type	Name	Description
FrameGeometry	sourceFrame
FrameGeometry	destinationFrame

Returns

Boolean
