Abstract
An electromagnetic shielding device for an MRI apparatus having a fastener for fastening the shielding device to a shielding element in the apparatus so as to surround said opening of a cavity and which shielding device is electrically connected to ground, wherein the fastener electrically connects the shielding device to the shielding element at the cavity opening; wherein the shielding device is flexible and is cylindrical and/or in a truncated cone shape, and has at least a passage opening for the body part; the shielding device is adapted to be fastened or compressed at said opening to the body part with a predetermined force in such a way as to close said opening and generate a low-impedance electrical contact between the body part and said shielding device to prevent or reduce the infiltration of electromagnetic noise from outside to inside said detection cavity; the shielding device is made of a first inner conductive material layer and an outer insulating fabric layer; and further includes at least one additional electrically conductive material layer overlapping and electrically connected to the first inner electrically conductive material layer.
