Edge-enhanced tomographic imaging with parallel projection differences

It is remarked that the angular derivative is an image operation easily implemented in tomographic systems by calculating the adjacent projection differences in sequence. This operation emphasizes distribution gradients. Numerical and experimental tests (absorption objects) are shown.
