Member Enumeration Documentation

◆ SliceOrientation

enum camitk::Slice::SliceOrientation

Common slices orientation: axial, sagittal, coronal axial_neuro.

Axial, Sagittal and Coronal orientation are given in Radiologist point of view. The neurologist point of view is displayed in axial_neuro.

The ImageComponent is supposed to be given in RAI orientation ! (see Image Reorientation Action Documentation). AXIAL: from feet to head of the patient CORONAL: from the front to back of the patient SAGITTAL: from the right to left of the patient AXIAL_NEURO: from head to feet (other side of AXIAL)

ARBITRARY: any arbitrary orientation.

◆ Slice()

camitk::Slice::Slice	(	vtkSmartPointer< vtkImageData >	volume,
		SliceOrientation	AXIAL_ORIENTATION,
		vtkSmartPointer< vtkWindowLevelLookupTable >	lookupTable = `nullptr`
	)

Constructor.

◆ ~Slice()

camitk::Slice::~Slice ( )

override

virtual destructor

Member Function Documentation

◆ addProp()

bool camitk::Slice::addProp	(	const QString &	name,
		vtkSmartPointer< vtkProp >	prop
	)

overridevirtual

insert an additional prop, defining it by its name (default visibility = false)

Returns: true if the additional prop was added (i.e. another additional prop of the same name does not exist)

void camitk::Slice::reslicedToVolumeCoords	(	const double *	ijk,
		double *	xyz
	)

ijk	given resliced coordiantes (generally from a pixel picked in the pickPlane)
xyz	output (should be allocated before calling this function) volume coordinates (with image at the origin in RAI convention) computed from the inputTodo: put this method in abstract slice

x	The absciss value of the selected pixel
y	The ordinate value of the selected pixel
z	The depth value of the selected pixel. In the plane, it's always +/- 0.01 in order to the pixel actor to be visible over the slice.
