In an embodiment of the present invention, a vibrator for an elastic magnetic resonance image technique diagnoses the state of an object under test by providing fine vibrations to the object under test which is arranged on a gantry of magnetic resonance (MR) room through the elastic magnetic resonance image technique. The vibrator for the elastic magnetic resonance image technique comprises : a pneumatic producing unit which is installed outside the MR room and produces air pressure; a pneumatic transmission hose in which one end is located inside the MR room and the other end is connected to the pneumatic producing unit; a vibration body which is formed into a cylindrical shape having an opened one side and is connected to one side of the pneumatic transmission hose; a O-ring groove unit which is formed on the one edge of the vibration body along a circumferential direction of the vibration body; a vibration membrane which is installed on one side of the vibration body to form a hollow space in a space with the vibration body and forms the pneumatic provided to the hollow space through the pneumatic transmission hose as fine vibrations; an O-ring member which is fitted into the O-ring groove unit so that the edge of the vibration membrane is inserted into the O-ring groove unit; a sealing cover which is fitted into one side of the vibration body to cover the edge of the vibration membrane at the top of the O-ring member; and a vibration generating unit which generates fine vibrations by the pneumatic received from the pneumatic transmission hose when the pneumatic producing unit is operated.COPYRIGHT KIPO 2014
