Class ParallelBackprojector2D

java.lang.Object

edu.stanford.rsl.tutorial.parallel.ParallelBackprojector2D

public class ParallelBackprojector2D
extends java.lang.Object

Implementation of a simple parallel backprojector. In order to create the image, the angular range and the angular sampling and the detector element size and detector element sampling has to be defined. We show both, a ray driven and a pixel driven backprojector. See L. Zeng. "Medical Image Reconstruction: A Conceptual tutorial". 2009, page 8
