Abstract
An MRI apparatus has a waveform setting unit, an applying control unit, a reconstructing unit, and a display control unit. The waveform setting unit sets an asymmetric RF pulse Waveform. The applying control unit controls an application of a pulse in accordance with the RF pulse waveform. The reconstructing unit reconstructs an image based on a signal received by the application. The display control unit controls a display of the image.

11. An MRI apparatus for generating an MRI image using a binomial pulse for a same nuclide excitation, comprising:
-
a waveform setting unit configured to generate and set a deformed binomial pulse waveform by deleting a portion of the binomial pulse waveform and adding an flip angle calculated based on the deleted waveform to a rest of the waveform if a number of waves of the binomial pulse waveform is 3 or more; and an applying control unit configured to control application of a pulse in accordance with the deformed binomial pulse waveform set by the waveform setting unit.

12. An MRI apparatus for generating an MRI image using a binomial pulse for a same nuclide excitation, comprising:
-
a waveform setting unit configured to generate and set a deformed binomial pulse waveform by admeasuring an intensity or a flip angle which should be used for one waveform included in the binomial pulse waveform to the other waveform; and an applying control unit configured to control application of a pulse in accordance with the deformed binomial pulse waveform set by the waveform setting unit.
