Detailed Description

template<class TInputImage, class TOutputImage>
class rtk::FieldOfViewImageFilter< TInputImage, TOutputImage >

Computes the field of view mask for circular 3D geometry.

Masks out the regions that are not included in our field of view or creates the mask if m_Mask is true. Note that the 3 angle parameters are assumed to be 0. in the circular geometry: GantryAngle, OutOfPlaneAngle and InPlaneAngle. The rest is accounted for but the fov is assumed to be cylindrical.

◆ AddCollimationConstraints()

template<class TInputImage , class TOutputImage >

void rtk::FieldOfViewImageFilter< TInputImage, TOutputImage >::AddCollimationConstraints	(	const FOVRadiusType	type,
		_lprec *	lp
	)

Add collimation constraints. This function is always called from ComputeFOVRadius but it has an effect only if the geometry has the m_CollimationUInf or m_CollimationUSup which are non infinity (default).

◆ BeforeThreadedGenerateData()

template<class TInputImage , class TOutputImage >

void rtk::FieldOfViewImageFilter< TInputImage, TOutputImage >::BeforeThreadedGenerateData ( )

overrideprotectedvirtual

Reimplemented from itk::ImageSource< TOutputImage >.

◆ ComputeFOVRadius()

template<class TInputImage , class TOutputImage >

virtual bool rtk::FieldOfViewImageFilter< TInputImage, TOutputImage >::ComputeFOVRadius	(	const FOVRadiusType	type,
		double &	x,
		double &	z,
		double &	r
	)

virtual

Computes the radius r and the center (x,z) of the disk perpendicular to the y-axis that is covered by:

if RADIUSINF: the half plane defined by the line from the source to the two inferior x index corners which cover the opposite two corners.
if RADIUSSUP: the half plane defined by the line from the source to the two superior x index corners which cover the opposite two corners.
if RADIUSBOTH: the fan defined by the pairs of half planes. Returns true if it managed to find such a disk and false otherwise. The function may be called without out computing the output, but m_Geometry and ProjectionsStack must be set.
