Abstract:
1. A method of reconstructing a tomographic image, comprising: a) forward-projecting said tomographic image along a list of individual geometrical lines using a graphics processing unit (GPU), wherein said individual geometrical lines comprise list-mode event data or a list of weighted lines, and wherein said forward-projecting comprises multiple independent forward projections of said tomographic image onto individual lines; wherein said forward-projecting further comprises: b) back-projecting said list of individual geometrical lines into a 3-dimensional volume using said GPU, wherein said back projecting comprises multiple independent back projections of said individual lines onto said 3-dimensional volume; c) utilizing results of said forward-projecting and said back projecting to reconstruct said tomographic image; and d) providing said reconstructed tomographic image as an output.
