Abstract
A nuclear magnetic resonance (NMR) tomography method for investigating a target object, wherein radio frequency (RF) pulses are irradiated into a target volume and/or RF pulses from the target volume are detected, wherein the target volume is determined by the frequency of the RF pulses and/or through magnetic field gradients, and wherein the target object is moved relative to the NMR tomograph during NMR data acquisition, is characterized in that the frequency of the RF pulses and/or the magnetic field gradients is/are changed during NMR data acquisition such that the target volume covered by the RF pulses is moved relative to the NMR tomograph at the same speed and direction of motion as the target object during NMR data acquisition. This provides a method for investigating a target object which moves relative to the NMR tomograph during NMR data acquisition, which can be carried out in a fast and simple manner.
