BRAIN ACTIVITY MEASUREMENT DEVICE AND BRAIN ACTIVITY MEASUREMENT METHOD

摘要

[Problem] Provided is a brain activity measurement device capable of strictly guaranteeing reproducibility of measurements performed using functional magnetic resonance imaging and performed across a plurality of times. [Solution] An MRI device (10) wherein a data processing unit (32) determines rigid body transformation between an original tomographic image captured during a previous measurement and stored in a storage unit (36) and a pilot tomographic image captured during current imaging, and corrects the slice image position and direction for tomographic images during current imaging, on the basis of the determined rigid body transformation parameters, such that the mutual information amount between the original tomographic image and the pilot tomographic image is maximized.
