REAL-TIME FMRI

The invention provides a method of medical imaging. The method comprises: receiving, for a current active time window (204A-N) and during a brain activity analysis session (200, 500), fMRI data of a region of interest (309) of a subject (318) in an active state. A transverse relaxation, T2*, map may...

Zusammenfassung:	The invention provides a method of medical imaging. The method comprises: receiving, for a current active time window (204A-N) and during a brain activity analysis session (200, 500), fMRI data of a region of interest (309) of a subject (318) in an active state. A transverse relaxation, T2, map may be generated from the fMRI data using a predefined model of fMRI data variations. The generated T2 map maybe compared with a reference T2* map. A blood-oxygen-level dependent (BOLD) response of the region of interest (309) during the current active time window (204A-N) may be estimated using the results of the comparison.
