Functions
std::pair< double, double >	getDetectorScaling (mat4 matrix, const ConeBeamGeometry &geom)
	Get the detector width and distance between detector plane and x-ray source for a projection matrix.
std::vector< vec2 >	project (SharedImageSet &cbData, int frame, std::vector< vec3 > in, ImageMath::CoordinateType coordinateType2d=ImageMath::CoordinateType::Texture)
	project 3D points onto a 2D plane, coordinate type of result is given by the coordinateType2d parameter.
std::vector< Geometry::LineSegment >	backproject (const SharedImageSet &cbData, int frame, std::vector< vec2 > in, ImageMath::CoordinateType coordinateType2d=ImageMath::CoordinateType::Texture)
	Computes the ray (world coordinates) from the source to a detector point, given by coordines in the detector plane using the coordinateType2d coordinate system.
void	makeConeBeamData (SharedImageSet &sis)
	Adjusts sis to fulfil the ConeBeamData concept, i.e. has ConeBeamMetadata, is topDown true, and has modality XRAY.
std::unique_ptr< SharedImageSet >	makeConeBeamData ()
	Generates a SharedImageSet that fulfils the ConeBeamData concept.
bool	isConeBeamData (const SharedImageSet &sis)
	returns true is sis is a valid representation of the concept ConeBeamData, i.e.
const ConeBeamMetadata &	getConeBeamMetadata (const SharedImageSet &sis)
	Shortcut to get ConeBeamMetadata from a SharedImageSet.
ConeBeamMetadata &	getConeBeamMetadata (SharedImageSet &sis)
	Shortcut to get ConeBeamMetadata from a SharedImageSet.
const DetectorPropertiesDataComponent &	createCurvedDetectorDataComponent (const SharedImageSet &sis)
	Shortcut to get or create DetectorPropertiesDataComponent from a SharedImageSet.
DetectorPropertiesDataComponent &	createCurvedDetectorDataComponent (SharedImageSet &sis)
	Shortcut to get DetectorPropertiesDataComponent from a SharedImageSet.
const DetectorPropertiesDataComponent *	getCurvedDetectorDataComponent (const SharedImageSet &sis)
	Shortcut to get DetectorPropertiesDataComponent from a SharedImageSet.
DetectorPropertiesDataComponent *	getCurvedDetectorDataComponent (SharedImageSet &sis)
	Shortcut to get DetectorPropertiesDataComponent from a SharedImageSet.

Function Documentation

getDetectorScaling()

std::pair< double, double > getDetectorScaling	(	mat4	matrix,
		const ConeBeamGeometry &	geom )

Get the detector width and distance between detector plane and x-ray source for a projection matrix.

Depending on which parameters are set in geom, this will use geom.detSizeX (generally) or geom.sourceDetDistance (for fan-beam systems) as the authoritative value.

isConeBeamData()

bool isConeBeamData

(

const SharedImageSet &

sis

)

returns true is sis is a valid representation of the concept ConeBeamData, i.e.

has ConeBeamMetadata, is topDown true, and has modality XRAY

getConeBeamMetadata() [1/2]

const ConeBeamMetadata & getConeBeamMetadata

(

const SharedImageSet &

sis

)

Shortcut to get ConeBeamMetadata from a SharedImageSet.

This method requires that the DataComponent exists in sis.components(). If this is not certain use isConeBeamData() to check first.

Deprecated

"Use ConeBeamMetadata::get(const SharedImageSet&) instead"

getConeBeamMetadata() [2/2]

ConeBeamMetadata & getConeBeamMetadata

(

SharedImageSet &

sis

)

Shortcut to get ConeBeamMetadata from a SharedImageSet.

Deprecated

"Use ConeBeamMetadata::get(SharedImageSet&) instead"

createCurvedDetectorDataComponent() [1/2]

const DetectorPropertiesDataComponent & createCurvedDetectorDataComponent

(

const SharedImageSet &

sis

)

Shortcut to get or create DetectorPropertiesDataComponent from a SharedImageSet.

It will get or create the DetectorPropertiesDataComponent in sis.components()

Deprecated

"Use DetectorPropertiesDataComponent::getOrCreate(const SharedImageSet&) instead"

createCurvedDetectorDataComponent() [2/2]

DetectorPropertiesDataComponent & createCurvedDetectorDataComponent

(

SharedImageSet &

sis

)

Shortcut to get DetectorPropertiesDataComponent from a SharedImageSet.

It will get the DetectorPropertiesDataComponent in sis.components() if exists, otherwise return a nullptr.

Deprecated

"Use DetectorPropertiesDataComponent::get(const SharedImageSet&) instead"

Deprecated

"Use DetectorPropertiesDataComponent::getOrCreate(SharedImageSet&) instead"

getCurvedDetectorDataComponent() [1/2]

const DetectorPropertiesDataComponent * getCurvedDetectorDataComponent

(

const SharedImageSet &

sis

)

Shortcut to get DetectorPropertiesDataComponent from a SharedImageSet.

It will get the DetectorPropertiesDataComponent in sis.components() if exists, otherwise return a nullptr.

Deprecated

"Use DetectorPropertiesDataComponent::get(const SharedImageSet&) instead"

getCurvedDetectorDataComponent() [2/2]

DetectorPropertiesDataComponent * getCurvedDetectorDataComponent

(

SharedImageSet &

sis

)

Shortcut to get DetectorPropertiesDataComponent from a SharedImageSet.

It will get the DetectorPropertiesDataComponent in sis.components() if exists, otherwise return a nullptr.
