Abstract |
AB |
[DE] Dargestellt und beschrieben ist ein Verfahren zur Erfassung von Störfeldern an einem Installationsort eines Magnetresonanztomographie-Systems, wobei die von einer externen Störquelle erzeugten statischen und/oder dynamischen Magnetfelder an dem Installationsort gemessen werden und wobei die Messung mit einem tragbaren oder transportablen Messgerät (1) zumindest vor der Installation des Magnetresonanztomographie-Systems an dem Installationsort vorgenommen wird.
[EN] The method involves measuring static and dynamic magnetic fields produced by an external interference source e.g. vehicle, at an installation place, using a portable measuring device (1) before installation of a magnet resonance tomography system at the installation place. The magnetic fields are measured at preset field intensity and a preset frequency. Vibrations are produced in the installation place by the external interference source. A gradient of the magnetic fields and a spatial distribution and strength of the vibrations are measured. An independent claim is also included for a measuring instrument for collecting perturbative fields at an installation place of a magnet resonance tomography system. |
