Recently, magnetic resonance imaging (MRI) devices are used in many medical institutions on the grounds of safety and convenience. An open-configuration MR system is introduced at Shiga University of Medical Science in order to conduct microwave coagulation therapy by using near-real-time MR images. However, this system has a fatal defect. When MRI device works to take images, it also generates serious noises (MR noise). Hence, an operator and other medical staff (ex. nurses and anesthetists… CONTINUE READING
