Abstract:
In an MR imaging system provided with an imaging volume disposed to receive a subject for acquisition of MR data, a removably insertable apparatus for reducing acoustic noise associated with operation of the MR system comprising,a substantially horizontal platform fixed within said imaging volume to support said subject during MR data aquisition; a frame which is removably insertable into said imaging volume for placement upon said platform, said frame, when in place upon said platform, defining a space within said imaging volume which is disposed to receive said imaging subject, at least a portion of said frame comprising a cylindrical section immediately surrounding a received subject, and a layer of material attached to said removably insertable frame, said material being insertable into said imaging volume with said fame and capable of absorbing substantial amounts of acoustic energy in the audio frequency range which is present in said imaging volume, said material also being highly transmissive to RF signals required for said MR data acquisition.
