Abstract:
Provided is magnetic resonance imaging (MRI) acoustic system that includes a magnet that is included in a bore having an image-taking space where an object is able to be accommodated and that forms a magnetic field in the image-taking space to obtain an MR image of the object, an electro-acoustic transducer that is located outside of the bore, and includes coils through which a current for generating an attraction force or a repulsion force with respect to the magnetic field generated by the magnet and a vibrating plate that vibrates in response to the an attraction force or the repulsion force, and a controller that controls the intensity of the current inputted to the electro-acoustic transducer to generate a sound by using the magnetic field that is generated by the magnet.
