Original Abstract

The magnetic resonance (MR) imaging techniques of tomography and spectroscopy are exploited in many applications. For the MR instruments to function properly it is necessary to maintain a high quality of homogeneity of the fundamental magnetic field. The pre-emphasis compensation of the generated gradient field increases the homogenity of the generated magnetic field and reduces the minimum switching times of the gradients. This enables measuring the MR images of incisions in the human body, the relaxation properties of nuclei, self-diffusion processes, flows of liquids and movements of solids faster and more accurately.
