Abstract

The present invention provides, in a magnetic resonance imaging device (MRD) comprising (a) a main longitudinal axis with a distal and proximal ends; (b) an open bore extended along the axis and terminated by an aperture located in the proximal end; and (c) a closure assembly which is shaped to fit the aperture; an RF shielding conduit (RFSC), having apertures shaped to permit passage of medical equipment tubing from the external environment of the MRD to inner space of the bore, affixed to the closure assembly, wherein the conduit is characterized by a length (l) and width (w), l:w ratio is greater than a predefined value n, thereby providing RF shielding.
