Apparatus for controlling the operation of an MRI system

An MRI system is provided that includes a physiological sensor used for gating the MRI system and an MRI control terminal wirelessly connected to the sensor. The physiological sensor is used to monitor a physiological parameter of a user, such as pressure pulse, and communicate data regarding the monitored physiological parameter to the MRI control terminal. The MRI control terminal processes the data received from the physiological sensor and determines whether a triggering condition on the data is met. When it is determined that the triggering condition is met, the MRI control terminal initiates the acquisition of a data set. The acquisition of the data set involves initiating a pre-programmed pulse sequence and acquiring RF signals emitted from the patient's tissue as a result of the execution of the pre-programmed pulse sequence.
