Constructor & Destructor Documentation

template<class TInterpolator >

cmtk::InverseInterpolationVolumeReconstruction< TInterpolator >::InverseInterpolationVolumeReconstruction	(	const UniformVolume *	originalImage,
		const int	numberOfPasses,
		const int	interleaveAxis
	)		[inline]

Constructor for interleaved image motion correction.

Take original image. Set interleaved image count and stacking axis. Construct separate 3D image stacks for interleaved passes. Allocate corrected image.

Parameters:

originalImage	Smart pointer to the original image with motion artifacts.
numberOfPasses	The number of interleaved passes, i.e., the number of pass images that comprise the final image.
interleaveAxis	Between-slice axis of the interleaved acquisition.
