Monitoring patients' cooperation for a given cognitive task is required in the clinical fMRI. The current study is aiming to develop a real-time fMRI platform to monitor the patient performance during the language task, which is usually done covertly. Successive estimation of task-related activation, deactivation and inter-regional connectivity was performed to evaluate patient's task involvement. The effect of scan numbers was assessed to determine minimal scan numbers in detecting the brain status. The preliminary results demonstrated the feasibility of real-time patient monitoring in the neurosurgical application of fMRI.
