Document Type and Number:
Japanese Patent JP2737608
Kind Code:
B2
Abstract:
A magnetic resonance imaging apparatus using NMR phenomenon includes a main magnet, a first to a third gradient field coils, a RF coil, a gradient field controller, a RF controller and a data processor. The main magnet generates a uniform static magnetic field in a imaging space. The first to third gradient field coils for generating three gradient field pulses with magnetic strength varying in three orthogonal directions in the imaging space. The RF coil for transmits a RF signal and detects an NMR signal. The gradient field controller causes the first gradient field coil to generate a slice-selecting gradient field pulse the second gradient field coil to generate a phase-encoding gradient field pulse, causes the third gradient field coil to generate a reading gradient field pulse the RF controller causes the RF coil to transmit the RF signal and to apply a RF signal (MTC pulse) having a frequency slightly offset from a resonance frequency of free water protons.
