Abstract

See full text

To efficiently generate an accurate morphological image and the temperature change distribution image, a pulse sequence for acquiring a plurality of echo signals having different echo times is executed, while excited spins are encoded with the same phase. Among thus obtained plural echo signals, the echo signal 405 acquired in the echo time TE1 suitable for obtaining morphological information (anatomic information) is used to reconstruct a morphological image. Further, the PPS method is applied to the echo signal 406 acquired in the echo time TE2 suitable for thermometry so as to generate the temperature change distribution image. The echo signal used for generating the morphological image may be a spin echo signal or a gradient echo signal.
