  • Method and apparatus for preventing artifacts due to magnetic field outside of field of view
    Patent number: 6498485
    Abstract: In order to provide a gradient magnetic field application method and apparatus for preventing artifacts due to a magnetic field outside a field of view (FOV), and a magnetic resonance imaging apparatus employing such a gradient magnetic field application apparatus, in performing a plurality of RF excitations of spins of atomic nuclei within a subject to be imaged in the presence of a gradient magnetic field and producing an image based on magnetic resonance signals generated by the spins, at least the polarity of the gradient magnetic field in a first RF excitation (G90) and the polarity of the gradient magnetic field in the next RF excitation (G180) are made opposite to each other.
    Type: Grant
