For clinical fMRI applications, it is desirable that parameter estimates and statistical results be displayed in real-time. An fMRI retinotopy experiment was conducted using a random visual field excitation paradigm. Real-time mapping of the visual field was simulated, post-experiment, using recursive, multi-parameter Kalman filter estimation of the visual field sensitivity profile for each voxel.
