Simulation of CT reconstruction artifacts associated with multiple-rotation fan-beam data collection.
Artifacts in reconstructed image caused by the errors in projection data depend on the source of the error itself, on the data collection mode and on the reconstruction algorithm. The effect of the multiple-rotation fan-beam data collection modes and corresponding reordered parallel convolution-backprojection algorithms on reconstruction artifacts of this type is analysed.
