Method Detail

backprojectRayDrivenCL

public Grid2D backprojectRayDrivenCL(Grid2D sino)

backprojectRayDriven

public Grid2D backprojectRayDriven(Grid2D sino)

Ray driven implementation of the Backprojector. This methods still contains a bug. ParkerWeighting does not work. Use Pixel-Driven instead.

Parameters:

sino - the sinogram for backprojection

Returns:

the backprojected image

backprojectPixelDrivenCL

public Grid2D backprojectPixelDrivenCL(Grid2D sino)

backprojectPixelDriven

public Grid2D backprojectPixelDriven(Grid2D sino)

The pixel driven solution for back-projection.

Parameters:

sino - the sinogram

Returns:

the image

backprojectPixelDriven_HighResRegion

public Grid2D backprojectPixelDriven_HighResRegion(Grid2D sino,
                                          float PixelScaling,
                                          double[] ROIcenter)

The pixel driven solution for back-projection in a given range and with a given resolution.

Parameters:

sino - the sinogram

Returns:

the image
