摘要： The invention relates to a magnetic resonance imaging system which comprises means for generating a static magnetic field and a gradient coils system for generating a time varying magnetic gradient field by use of a first electrical current and a second electrical current. The gradient coils system is located in the magnetic field and the gradient coils system has a plurality of vibrational modes. Lorentz forces are generated due to the interaction of the first and/or second electrical currents with the superposition of the static magnetic field and the magnetic gradient field. The gradient coils system and/or the first electrical current are adapted so that the integral of the in-products of said Lorentz forces and a vibrational mode of said plurality of vibrational modes is at a value close to zero, wherein said in-products are determined for all points of the gradient coils system, and wherein the integral is determined by summing the in-products determined for all the points. As the above mentioned integral is close to zero or preferably zero, the Lorentz forces are not able to excite the vibrational mode (for example the lowest order bending mode) of the gradient coils system. Thus acoustical noise that is generated by a vibrating gradient coils system is reduced and the comfort for a patient that is examined by the magnetic resonance imaging system is therefore enhanced.

摘要： A panel-acoustic transducer comprises a plate-like actuator (4) and a panel (5). The panel (5) has two substantially perpendicular axes of symmetry (AS,Al). The plate-like actuator (4) is coupled to the panel in such a way that: —the actuator (4) is coupled to the panel substantially symmetrically with respect to both symmetry axes (AS,Al) of the panel (4); the plate-like actuator (4) is so arranged that, in operation, at least the first five odd excitation modes ((1,1), (3,1), (1,3), (3,3), (5,1)), in order of increasing frequency, are actuated with alternating signs. Cusps in the power spectrum of the transducer are thereby prevented.
