Constructor & Destructor Documentation

template<class TPSF >

cmtk::DeblurringVolumeReconstruction< TPSF >::DeblurringVolumeReconstruction	(	const UniformVolume *	originalImage,
		const size_t	numberOfPasses,
		const int	interleaveAxis,
		const Types::Coordinate	psfScale = `1.0`
	)		`[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.
psfScale	Optional spatial scale factor for the PSF. Values larger than 1 increase PSF size, smaller than one decrease it.
