MAGNETIC RESONANCE IMAGING SYSTEM WITH REDUCED UNINTENTIONAL MECHANICAL MOVEMENTS

摘要

A magnetic resonance imaging (MRI) system (1) with an active vibration control is provided, in that a number of piezo-electric actuators (6) are positioned between at least one element (2, 3, 5, 9, 10) of the MRI system (1) and an associated support surface (8) and being connected in series with each other; and a control unit (11, 11 ') is adapted to actively control the displacement of the number of piezo-electric actuators (6) in a way that unintentional mechanical movements of the MRI system (1) are reduced.
