1. A magnetic resonance imaging apparatus comprising:
- a data acquiring unit configured to acquire a signal train of magnetic resonance signals from an object by a spin echo method for applying a refocus pulse repeatedly following an excitation pulse with changing a flip angle of the refocus pulse; and
an image generating unit configured to generate frames of image data having mutually different contrasts, based on mutually different portions of the signal train of the magnetic resonance signals.

2. A magnetic resonance imaging apparatus comprising:
-
a data acquiring unit configured to acquire a signal train of magnetic resonance signals from an object by a spin echo method for applying a refocus pulse repeatedly following an excitation pulse with changing a flip angle of the refocus pulse, along a sweep pattern representing a change of the flip angle appropriate for mutually different contrasts; and an image generating unit configured to generate frames of image data having the different contrasts, based on mutually different portions of the signal train of the magnetic resonance signals.
