Parabolic Radon transform and x-squared fk-transform - aliasing and efficiency

Abstract

this paper the aliasing is studied by comparing the PRT with the Nonuniform Discrete Fourier Transform (NDFT). Although we find the same main principals, there are some differences. Moreover, the new points of view can provide a better understanding of the results found. The similarity between the PRT and the NDFT can also be used for the utilization of fast algorithms
