| titleOfInvention | Magnetic resonance apparatus |
| abstract | A magnetic resonance apparatus acquires a magnetic resonance signal matrix as follows. While a gradient field is applied to an object to be examined, a plurality of selective inversion pulses having different frequencies as high-frequency fields are sequentially applied to the object. Thereafter, a non-selective excitation pulse as a high-frequency field is applied to the object without application of a gradient field. In addition, a magnetic resonance signal generated upon application of the non-selective excitation pulse is acquired. Such a series of sequences are repeated a plurality of times, while the frequencies of the selective inversion pulses are sequentially selected to cause a magnetization vector of a nuclear spin of an area corresponding to either of "-1" and "1" an Hadamard matrix to be inverted by each selective inversion pulse. Chemical shift information is obtained by transforming a magnetic resonance signal matrix thus acquired in an aligning direction of the magnetic resonance signal matrix by an inverse Hadamard transform, and transforming the transformed matrix in a time base direction by an inverse Fourier transform. |
