摘要: In one embodiment, a method of tomographic image construction includes performing sparsification on initial projection data for an object with a processor to provide sparsified projection data of the object. The method also includes backprojecting the sparsified projection data with the processor to provide a three-dimensional image of the object, and performing sparsification on the three-dimensional image with the processor to provide a sparsified image.
