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 single scan using a spin echo method repeatedly applying a refocus pulse, with changing flip angles, following an excitation pulse, a first sweep pattern of changing flip angles and a different second sweep pattern of changing flip angles being mixed in the single scan; and
an image generating unit configured to generate first image data corresponding to the first sweep pattern and second image data corresponding to the second sweep pattern, using the signal train acquired by the single scan, the first image data, and the second image data having different contrasts.

Abstract
According to one embodiment, a magnetic resonance imaging apparatus includes a data acquiring unit and an image generating unit. The data acquiring unit is 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. The image generating unit is configured to generate frames of image data having different contrasts, based on different portions of the signal train of the magnetic resonance signals.
