The three-dimensional projection reconstruction is to reconstruct a three-dimensional image, or a three-variable function to be more general, from a set of its plane integrals onto lines. A projection refers to such an integral. This reconstruction problem arises for instance in zeugmatographic, magnetic resonance imaging. A method based on the inverse Radon transform is already known for the three-dimensional reconstruction. However, the quality of the images reconstructed by numerical computation of this transform has not been made clear. We have studied the image property by computer simulation. We reconstructed spherical objects and studied the directionality and an approximation to the point spread function of the method.
