We propose the ANFIS used for region of interest (ROI) detection in brain fMRI images. The ROI is used for estimating the tissue activity by Blood-Oxygen Level Dependent technique (BOLD). The result shows the ANFIS model can be used to fit the image time-intensity data. A 3 Gaussian membership functions were proposed to estimate the time-intensity relation. The result shows the rate of time-intensity relation to determine the tissue activity. The tissue activity should be determined the normal pattern of reading process. © 2011 IEEE.Mahidol UniversityEngineeringConference PaperSCOPUS10.1109/BMEiCon.2012.6172065
