Abstract

In this paper, we will introduce a resampling method for in vivo projection reconstruction (PR) magnetic resonance (MR) signals. We will describe the physical processes causing the inaccurate sampling of these signals. Based on the theoretical properties of the signal, a technique to reduce the influence of this effect on the signals will be proposed. The method will be validated using simulations and in vivo MR signals. The corrected signals will be shown to be a better approximation of the signals that would be expected on a theoretical basis.
