AllocateImageAfterAdjoint()

void NoImageAcquisition::AllocateImageAfterAdjoint ( )

protectedvirtual

Note: This implementation is different to the reference implementaiton in reg_resp which adjusted the image size of the adjoint regardless of which acquisition simulation was selected. This could lead to a segmentation fault in some specific cases. As a result, here the image size is not adjusted for the no-image-acquisition class.

Implements ImageAcquisition.

AllocateMinimumSizeImgInFullImgSpace()

nifti_image * NoImageAcquisition::AllocateMinimumSizeImgInFullImgSpace ( nifti_image *  imgInFullImgSpace, nifti_image *  imgInAcquisitionSpace, unsigned int  dynamicImageTimePoint  )

virtual

Implementation of allocating the minimum-sized image in full image space. Here no image acquisition is simulated, hence the allocated image has to have the size of the image in acquisition space.

Parameters

imgInFullImgSpace	The full sized image
imgInAcquisitionSpace	The image in acquisition space
dynamicImageTimePoint	Time point of the dynamic image (not used).

Returns

An empty image with the size of imgInAcquisitionSpace

Implements ImageAcquisition.

CalculateAdjoint()

void NoImageAcquisition::CalculateAdjoint ( nifti_image *  imgInFullImgSpace, nifti_image *  imgInAcquisitionSpace, unsigned int  dynamicImageTimePoint  )

virtual

To achieve the required behaviour when not simulating any image acquisition, copy current image in acquisition space into the image after applying the adjoint. Image after adjoint still needs to be accessed via the corresponding getter function.

Parameters

imgInFullImgSpace	The full sized image
imgInAcquisitionSpace	The image in acquisition space
dynamicImageTimePoint	Time point of the dynamic image (not used here).

Implements ImageAcquisition.

SimulateImageAcquisition()

nifti_image * NoImageAcquisition::SimulateImageAcquisition ( nifti_image *  imgInFullImgSpace, nifti_image *  imgInAcquisitionSpace, unsigned int  dynamicImageTimePoint  )

virtual

Implementation of the image acquisition simulation. Since no image acqusition is simulated, the image in full space is simply returned. This needs to be considered when deleting images, check for equality.

Parameters

imgInFullImgSpace	Pointer to nifti image holding the image in full image space.
imgInAcquisitionSpace	Pointer to the nifti image in acquisition space.
dynamicImageTimePoint	The dynamic image time point in case time-dependent meta data needs to be used internally.

Implements ImageAcquisition.
