Voice Capture Device, Voice Capture Method, and Program

摘要

This invention is a technology developed to clearly obtain voice produced by a subject being measured by using MRI (magnetic resonance imaging) equipment for the purpose of brain informa tion research. MRI equipment uses a powerful superconducting magnet to quickly change the mag netic field in taking pictures, so that a strong pulse-like current flows through the coil. Subsequent coil vibrations generate intense MRI equipment noise and electromagnetic induction noise, along with other types of noise. Consequently, it has thus far been impossible to clearly obtain voice pro duced by the subject while operating the MRI equipment. This invention is an idea conceived as one solution to address that problem.
