発明の名称 (英語) MAGNETIC RESONANCE DEVICE AND METHOD 新技術説明会
発明の概要(英語) The purpose of the present invention is to provide a magnetic resonance device having new element technology which detects a magnetic resonance signal with a high sensitivity. The magnetic resonance device is provided with: a magnetic field generating unit 1 which generates a magnetic field to be applied to a sample S; an excitation high frequency generating unit 2 which generates an excitation high frequency; a transmission coil 31 which irradiates the sample S disposed in the magnetic field, with the excitation high frequency; a reception coil 41 which receives a magnetic resonance signal generated by the sample S excited by the excitation high frequency; an electrical-to-mechanical transducer 42 which transforms a voltage of the magnetic resonance signal to a vibration of a capacity coupling film M; and a vibration measuring unit 5 which measures the vibration of the film M on the basis of optical interference.
従来技術、競合技術の概要(英語) BACKGROUND ART
Nuclear magnetic resonance (NMR: Nuclear Magnetic Resonance) device, and to analyze the sample, arranged in the static magnetic field space of the sample being irradiated with the high frequency excitation, in the sample measurement object included in the nuclear magnetic resonance signal emitted from the nuclei of the detected device. The frequency of the high-frequency excitation is applied, the magnitude of the static magnetic field is applied, nuclear spins in the sample to be observed according to the type has been determined, a nuclear magnetic resonance frequency may be referred to as the resonant frequency.
In general, such a signal obtained by the nuclear magnetic resonance phenomenon, the energy to be handled becomes extremely small, essentially in a weak signal. Therefore, a nuclear magnetic resonance in a high sensitivity is an important question.
In the following Patent Document 1, between the transmission coil and receiving coil of the electromagnetic coupling by reducing the influence of, so as to improve the detection sensitivity of the probe for a nuclear magnetic resonance apparatus has been disclosed.
In the following Patent Document 2, by digital quadrature lock-in detection methods, nuclear magnetic resonance signal of high sensitivity reception method is disclosed.
Non-Patent Document 1 and Patent Document 3 is the following, a method for optically detecting the radio wave by a nanomechanical transducer has been disclosed.
