ABSTRACT:
A computed tomography apparatus which generates an image of an examined subject using Fourier reconstruction with a gridding algorithm operates so that this algorithm is efficiently implemented by employing a hardware unit in the form of an ASIC, which produces the additional formation of contributions in the Cartesian frequency matrix, derived from the polar support points.
